§56-3-645: BEV $120 / PHEV&hybrid $60 biennial
Sets millage + flat fees for property tax
Base reg e.g. 4,001–5,000 lb = $40 biennial
Used only if “use sales tax instead of IMF”
~3–4 mi/kWh typical BEV
~half of biennial base + DMV
South Carolina electric vehicle owners pay a biennial $120 registration surcharge on battery-electric vehicles and $60 on plug-in hybrids and conventional hybrids, on top of normal weight-based registration. At titling, most dealer purchases trigger an Infrastructure Maintenance Fee of 5% of the purchase price, capped at $500, instead of standard sales tax in many cases. Counties also levy an annual vehicle property tax on assessed value. Home electricity averages about 16 cents per kilowatt-hour statewide—below the national average—with Duke Energy, Dominion Energy South Carolina, and Santee Cooper offering time-of-use and EV programs. South Carolina offers no state EV purchase rebate in 2026, and federal Clean Vehicle credits generally expired after September 30, 2025. This guide explains every major South Carolina EV fee and energy cost in plain English, with step-by-step examples.
South Carolina has charged dedicated EV and hybrid registration fees since 2018 under Act 3516, codified in S.C. Code §56-3-645. Battery-electric and fuel-cell vehicles pay $120 every two years; plug-in hybrids and other hybrid vehicles that use both motor fuel and electricity pay $60 every two years. These amounts are collected at titling or renewal and go to the Infrastructure Maintenance Trust Fund, replacing some gasoline tax EV drivers do not pay at the pump.
Unlike Michigan’s fuel-tax-indexed surcharge, South Carolina’s EV fee is a flat biennial amount—unless future legislation passes. Senate Bill 831 in 2025 proposed raising the BEV fee substantially but did not become law as of 2026. Calculators should use $120 / $60 unless the General Assembly enacts changes.
Upfront titling often includes the IMF cap of $500 on many new cars, which can be less than 6% sales tax on a $40,000 vehicle ($2,400) but still adds to first-year cash. Ongoing county property tax varies by where you register—Greenville, Richland, Charleston, and other counties publish vehicle tax estimators online.
Operating cost favors home charging: EIA data for May 2026 put South Carolina residential electricity near 16.2 cents per kWh. Duke and Dominion time-of-use plans, plus Duke’s off-peak EV bill credit (about $7.50 per month on qualifying programs), can lower effective charging cost further. This guide is for South Carolina shoppers, Upstate and Lowcountry EV owners, and anyone building a fee or total-cost-of-ownership tool.
How South Carolina EV fees evolved
South Carolina’s EV registration surcharge did not appear overnight. The General Assembly passed Act 3516 in 2017, and the fees took effect in January 2018. At that time, lawmakers set a flat biennial amount—$120 for vehicles powered exclusively by electricity or hydrogen, and $60 for vehicles that combine motor fuel with electricity. Act 70 in 2021 clarified when and how SCDMV collects those amounts at titling and renewal. Revenue flows to the Infrastructure Maintenance Trust Fund, the same fund that receives IMF proceeds and gasoline tax revenue.
In 2025, Senate Bill 831 proposed raising the BEV fee substantially—well above the current $120 level—but that bill did not become law as of 2026. Calculators and budget planners should continue to use $120 and $60 unless the Legislature enacts a change. South Carolina does not currently impose a per-mile road-use charge on EVs; the biennial flat fee is the primary EV-specific road funding mechanism.
South Carolina also does not offer a special “EV” license plate with fee waivers or HOV lane privileges. EVs and hybrids use standard plates and pay the same specialty plate surcharges as any other vehicle if the owner chooses a college, vanity, or organizational plate (often $40 to $160 biennially on top of base fees).
Biennial EV and Hybrid Registration Fees
Under S.C. Code §56-3-645:
- Battery-electric or hydrogen (fuel-cell) vehicle: $120 every two years
- Plug-in hybrid or hybrid using motor fuel and electricity: $60 every two years
- Conventional gasoline vehicle: $0 additional EV/hybrid fee
The fee is in addition to the normal biennial registration fee based on weight. It is not prorated as a per-mile charge. Fuel-cell vehicles count as exclusively electric for this purpose.
Example 1: BEV Annualized EV Fee
Scenario: Battery EV; $120 collected every two years at renewal.
Biennial EV surcharge: $120.00 Annualized equivalent: $60.00/yr (vs. $0 for pure ICE registration add-on)
Example 2: PHEV vs. BEV Over Four Years
Scenario: Two renewals in four years.
BEV: 2 × $120 = $240 over 4 years ($60/yr avg) PHEV: 2 × $60 = $120 over 4 years ($30/yr avg) BEV pays $120 more over 4 years than PHEV
Non-plug hybrids (standard Prius-class) also pay the $60 biennial hybrid fee because they use both fuel types under the statute’s wording.

Base Registration Fees by Weight
South Carolina’s base vehicle registration fee is biennial and depends on gross vehicle weight. Passenger EVs typically fall in the lighter brackets:
- 0–4,000 lbs: $30
- 4,001–5,000 lbs: $40
- 5,001–6,000 lbs: $50
- Continuing in roughly $10 increments per 1,000 lbs through higher classes
- 9,001–10,000 lbs: $110 (example from SCDMV schedule)
A typical 4,500-pound EV might pay $40 base registration plus $120 EV fee every two years—$160 total biennial, or $80 per year averaged. Heavier trucks and large SUVs climb the schedule: an 8,200-pound vehicle might pay $80 biennial base registration, and a 9,500-pound vehicle might pay $110. South Carolina also assesses a small annual SCDMV fee (commonly cited as $1 per year) on top of the biennial weight fee.
| Weight range (lbs) | Biennial base fee | Typical vehicle examples |
|---|---|---|
| 0–4,000 | $30 | Compact EVs, small sedans |
| 4,001–5,000 | $40 | Mid-size EVs (Model 3, Ioniq 6) |
| 5,001–6,000 | $50 | Crossover EVs, many PHEV SUVs |
| 6,001–7,000 | $60 | Large crossover, light truck |
| 7,001–8,000 | $70 | Full-size SUV, pickup |
| 8,001–9,000 | $80 | Heavy SUV, electric truck |
| 9,001–10,000 | $110 | Large truck, commercial van |
Most battery-electric passenger cars sold in 2026 fall between 4,000 and 6,000 pounds, putting base biennial registration in the $40 to $50 range before the $120 EV surcharge.
Example 1: 5,500 lb SUV EV Biennial Registration
Scenario: Weight bracket 5,001–6,000 lbs; BEV.
Base biennial registration: $50.00 Biennial EV surcharge: $120.00 SCDMV annual fee (approx.): $2.00/yr ────────────────────────────────────────── Biennial total: $170.00 Annualized: $85.00/yr
Example 2: Same Weight ICE (No EV Fee)
Base biennial registration: $50.00 EV surcharge: $0.00 ────────────────────────────────────────── Biennial total: $50.00 EV premium (biennial): $120.00

Infrastructure Maintenance Fee, Title, and Titling
South Carolina replaced traditional sales tax on many vehicle purchases with an Infrastructure Maintenance Fee (IMF) under S.C. Code §56-3-627 and related provisions:
- Dealer purchase: 5% of purchase price (gross proceeds), capped at $500
- Private sale: 5% of fair market value, capped at $500
- First-time out-of-state vehicle brought into SC: one-time $250 titling fee in defined situations
When IMF applies, standard sales tax often does not—but high-value transactions and specific fact patterns may differ. Title fees and registration card fees (commonly cited around $15 title and small document fees) add to the stack. Plan roughly $30 in standard DMV titling charges plus IMF.
IMF vs. sales tax: which applies?
This distinction confuses many first-time South Carolina buyers. The IMF is a 5% fee on the vehicle purchase price, capped at $500. South Carolina’s state sales tax rate is 6%, and many counties add a local option tax of up to about 2%, for a combined rate that can reach 8% in some jurisdictions. On a $40,000 vehicle, 6% sales tax alone is $2,400—far more than the $500 IMF cap. That is why IMF often saves money at titling on mid- and high-priced vehicles.
On lower-priced vehicles, the math reverses. A $6,000 used car triggers IMF of $300 (5% × $6,000), which may be less than sales tax would have been at 7% ($420). The cap binds at $10,000 purchase price: 5% of $10,000 equals exactly $500. Any vehicle priced above $10,000 pays the flat $500 IMF maximum when IMF rules apply.
Gasoline vehicles purchased from dealers may be subject to IMF or sales tax depending on transaction structure and vehicle type. EV buyers should not assume IMF always applies—confirm with the dealer and SCDMV. Private-party sales use fair market value for the 5% calculation rather than the sticker price.
Example 1: IMF on $40,000 New BEV From Dealer
Scenario: 5% of price = $2,000, but cap binds.
5% of $40,000 = $2,000.00 IMF cap: $500.00 ────────────────────────────────────────── IMF due at titling: $500.00
Any vehicle hitting the cap pays the same $500 IMF regardless of whether it is electric or gasoline.
Example 2: IMF on $8,000 Used EV
Scenario: Private or dealer sale below cap threshold.
5% of $8,000 = $400.00 Cap not binding ────────────────────────────────────────── IMF due: $400.00
Important: If 5% of purchase price is under $500, IMF equals 5%. If ICE purchase is taxed under sales tax instead of IMF in your transaction, 6% state tax plus local option tax (up to about 2% in some counties) may apply instead—confirm with dealer or SCDMV for your deal structure.

County Vehicle Property Tax
South Carolina counties levy an annual ad valorem property tax on vehicles. Tax is assessed on vehicle value using county millage rates—often roughly 0.5% to 1% of value in planning examples, but varies by county and assessment method. Many counties provide online vehicle tax calculators (Richland, Greenville, and others).
Vehicle property tax is usually paid one year in advance at registration renewal. Include county in any calculator; defaults can use a statewide midpoint for illustration only.
South Carolina assesses vehicles using a declining-value method in many counties. A new car’s assessed value may start near purchase price and decrease each year according to county schedules. Millage rates vary: Greenville County, Richland County (Columbia area), Charleston County, and Horry County (Myrtle Beach area) each publish separate rate tables. A millage rate of 300 mills on $50,000 assessed value means 300 ÷ 1,000 × $50,000 = $150 in tax, but actual county formulas include assessment ratios and exemption credits that make online estimators the most reliable source.
For budgeting purposes, many planners use 0.5% to 1.0% of vehicle value as an annual property tax range. A $35,000 EV might cost $175 to $350 per year depending on county and year of ownership. This tax applies equally to EVs and gasoline cars—there is no EV exemption.
Example 1: Property Tax at 0.7% on $50,000 Value
Scenario: Year-one assessed value near purchase price; illustrative rate.
Assessed value: $50,000 Millage equivalent 0.7%: $350.00/yr (+ biennial reg and EV fee lines)
Example 2: Same Car in Lower-Mill County (0.5%)
Property tax: $50,000 × 0.005 = $250.00/yr Savings vs. 0.7% county: $100.00/yr

South Carolina Electricity Rates and Charging Costs
U.S. EIA Electric Power Monthly data for May 2026 cite South Carolina average residential electricity near 16.18 cents per kWh and commercial near 11.6 cents per kWh—below the U.S. average.
Major utilities (2026 planning figures)
- Duke Energy Carolinas: roughly 14 cents/kWh residential; off-peak EV programs and about $7.50/month credit on qualifying EV charging riders
- Dominion Energy South Carolina: roughly 15 cents/kWh; new time-of-use with peak hours 4–8 p.m. from July 2026
- Santee Cooper: roughly 11 cents/kWh with EV time-of-use options
- Municipal and cooperatives: often 12–16 cents/kWh
Public Level 2 and DC fast charging typically cost more than home rates—plan a 10% to 20% premium or higher for DCFC. Assume about 90% charging efficiency for home Level 2. Charging efficiency accounts for energy lost in the inverter, battery management system, and cable—so the grid delivers slightly more kilowatt-hours than the battery stores.
| Provider | Service area | Rate (¢/kWh) | Notes |
|---|---|---|---|
| Duke Energy Carolinas | Upstate, western SC | ~13.9 | EV off-peak credit ~$7.50/mo |
| Dominion Energy SC | Midlands, coastal SC | ~15.1 | TOU peak 4–8 p.m. (July 2026) |
| Santee Cooper | Statewide (co-op areas) | ~11.4 | EV TOU and charger rebates |
| Municipal & co-ops | Various cities | 12–16 | Greenville, Columbia, Horry, etc. |
| EIA statewide average | All residential | 16.18 | May 2026 data |
Duke Energy Carolinas filed for a roughly 4.3% rate increase effective August 2026. Dominion’s approved 2025 settlement raised typical bills about 7.6%. When building a long-term ownership estimate, consider that electricity rates may rise over five or ten years, though EV efficiency gains and off-peak programs can offset part of that increase.
For public charging, Electrify America, ChargePoint, and Tesla Supercharger networks in South Carolina often charge $0.35 to $0.50 per kWh or bill by the minute. A driver who charges 20% of miles on the road at $0.40/kWh and 80% at home at $0.15/kWh will pay more than an all-home-charging owner. Calculators should let users split home vs. public charging share.
Example 1: Annual Home Charging (12,000 mi, 3.5 mi/kWh)
Scenario: 90% efficiency; $0.162/kWh statewide average.
Car energy: 12,000 ÷ 3.5 ≈ 3,429 kWh Grid draw: 3,429 ÷ 0.90 ≈ 3,810 kWh Cost: 3,810 × $0.162 = $617.22/yr Cost per mile: ≈ 5.1¢
Example 2: Duke Off-Peak vs. Dominion Peak Mix
Scenario: 85% charging at $0.12 off-peak; 15% at $0.18 peak; same grid kWh.
Off-peak 85%: 3,239 × $0.12 = $388.68 Peak 15%: 571 × $0.18 = $102.78 ────────────────────────────────────────── Annual electricity: $491.46 Minus Duke EV credit (~$7.50/mo): ~$90/yr Net after credit (illustrative): ~$401/yr

Incentives and Expired Credits
Federal purchase credits: IRC §30D (up to $7,500 new) and §25E (up to $4,000 used) generally expired for vehicles acquired after September 30, 2025. No federal purchase credit on typical 2026 South Carolina buys unless law changes.
Home charger credit (IRC §30C): 30% up to $1,000 for qualifying residential charger installs placed in service before July 1, 2026. After that date the credit phases out under current guidance.
South Carolina state: No direct EV purchase rebate or sales-tax exemption. S.C. Code §12-28-110 provided a 25% alternative fueling infrastructure credit (charger installations) on a phased schedule; the relevant credit period for new claims ended around January 1, 2026 for many projects—confirm with the Department of Revenue for any carryforward.
Utility programs: Santee Cooper, York Electric Cooperative, and others offer EV time-of-use rates or charger rebates. Enter utility-specific amounts if applicable.
Other federal provisions: The 2024 One Big Beautiful Bill Act temporarily allowed deduction of EV loan interest up to $10,000 per year for qualifying borrowers, but eligibility rules are complex and the provision is scheduled to expire in 2029. Most South Carolina buyers in 2026 will not see a direct purchase rebate from state or federal sources. The practical incentives left are lower operating cost from cheap home electricity, possible utility TOU savings, and the home charger tax credit if installed before July 2026.
Santee Cooper’s residential EV programs include time-of-use rates that reward overnight charging and rebates for Level 2 home charger installation in some service territories. York Electric Cooperative offers similar EV rate riders. These programs change periodically—check your utility’s website when you plug in your address.
Example 1: Charger Install With Federal §30C Only
Scenario: $1,200 install completed June 2026; eligible for §30C.
Install cost: $1,200.00 Federal credit 30% (max $1,000): -$360.00 State infrastructure credit: $0 (2026) ────────────────────────────────────────── Net after federal credit: $840.00
Example 2: 2026 Purchase With No Credits
Federal §30D / §25E: $0 South Carolina purchase rebate: $0 Full IMF and property tax apply

How a South Carolina EV Cost Calculator Works
A South Carolina calculator should combine titling IMF, biennial registration (base + EV fee), county property tax, and electricity, then compare to ICE fuel and fees.
Recommended inputs
- Vehicle type: BEV, PHEV, hybrid, or ICE
- Purchase price; dealer vs. private; out-of-state transfer flag
- Empty or gross weight (base registration bracket)
- County (property tax millage or estimator output)
- Annual miles; mi/kWh or kWh/mi; charging efficiency
- Utility (Duke, Dominion, Santee Cooper, custom $/kWh)
- Home vs. public charging share
Core formulas
- IMF: min(5% × price, $500) when IMF applies; or $250 out-of-state fee when applicable.
- Biennial registration: weight fee + ($120 BEV or $60 hybrid/PHEV).
- Annualized reg: biennial total ÷ 2.
- Property tax: assessed value × county rate (from estimator).
- Annual energy: (miles ÷ mi/kWh) ÷ efficiency × $/kWh.
- ICE fuel: (miles ÷ mpg) × $/gal.
- TCO: price + IMF + sum of annual (energy + property tax + reg + EV fee annualized) over horizon.
Calculator inputs and defaults
A well-designed South Carolina EV cost calculator collects the inputs below. Defaults should reflect typical 2026 values so casual users get a reasonable estimate without researching every field.
| Input | Range | Default | Notes |
|---|---|---|---|
| Vehicle type | BEV, PHEV, hybrid, ICE | BEV | Sets $120 vs. $60 fee |
| Purchase price | $0–$200,000 | $50,000 | Drives IMF or sales tax |
| Model year | 2010–2026 | 2026 | Credit cutoff Sept. 2025 |
| Annual mileage | 0–50,000 mi | 12,000 | U.S. average ~12–13k |
| Utility provider | Dropdown list | Duke SC | Sets default $/kWh |
| Electricity rate | $0.06–$0.50/kWh | $0.16 | Override utility default |
| Charging location | Home / public | Home | Public adds ~20% premium |
| Charging efficiency | 70–95% | 90% | Includes inverter losses |
| Sales tax rate | 0–10% | 6% | State + local if IMF N/A |
| Registration county | SC counties | State average | Property tax millage |
| Purchase date | Date picker | Today | §30C charger deadline |
Step-by-step calculator flow
First, the user selects vehicle type and enters purchase price, weight class, and whether the purchase is from a dealer, private seller, or out-of-state transfer. The tool computes IMF (or sales tax if selected) and one-time title fees. Second, the user enters annual mileage, utility provider, and charging preferences. The tool calculates annual electricity cost and, if comparing to ICE, annual gasoline cost using a default MPG and fuel price the user can adjust.
Third, the user selects registration county or accepts a statewide average for property tax. Fourth, the results panel shows itemized upfront costs, annual recurring costs, and total cost of ownership at 1-, 3-, 5-, and 10-year horizons. A comparison chart plots cumulative EV cost against an equivalent gasoline vehicle. Per-mile energy and fuel costs appear prominently so drivers can see the operating-cost advantage even when upfront EV price is higher.
Example 1: Calculator Walkthrough — $50,000 BEV
Scenario: 6,000 lb class ($50 biennial base); BEV; 12,000 mi; 3.0 mi/kWh; $0.16/kWh; IMF $500; property tax $350/yr.
IMF (one-time): $500.00 Biennial reg: $50 + $120 = $170.00 Annualized reg + EV: $85.00 Energy: (12,000÷3)÷0.9 × $0.16 ≈ $711.11 Property tax: $350.00 ────────────────────────────────────────── Annual recurring (approx.): $1,146.11 ICE compare 30 mpg @ $3.50/gal: Fuel $1,400 + reg ~$25/yr + tax ~$280 ≈ $1,705/yr (no $120 EV line)
Example 2: Per-Mile Energy vs. Gasoline
EV: $0.16/kWh ÷ 3.0 mi/kWh ÷ 0.90 ≈ 5.9¢/mi (energy) Gas: $3.50/gal ÷ 30 mpg ≈ 11.7¢/mi (fuel) Fuel gap at 12,000 mi: ~$696/yr EV fee premium ~$60/yr (annualized) Net fuel+fee edge: ~$636/yr (before property tax parity)

Complete Example 2: $50,000 BEV vs. $40,000 ICE (5-Year Sketch)
Scenario: BEV IMF $500; ICE sales tax 7% = $2,800; similar property tax; BEV energy ~$640/yr; ICE fuel ~$1,400/yr.
5-yr BEV operating (energy+tax+reg): 5 × ~$1,070 ≈ $5,350 + $50,000 purchase + $500 IMF ≈ $55,850 5-yr ICE operating: 5 × ~$1,720 ≈ $8,600 + $40,000 + $2,800 tax ≈ $51,400 ICE lower total if purchase price lower and no credits; BEV saves ~$650/yr on fuel+fee net in many cases
Complete Example 3: PHEV ($35,000, 13,000 mi)
Scenario: 80% electric miles at 3.5 mi/kWh; 20% gas at 42 mpg; hybrid fee $60 biennial.

Complete Example 4: Out-of-State Transfer to Charleston
Scenario: 2024 BEV first titled in Georgia, moved to Charleston County in 2026. Purchase price when new was $45,000; current fair market value ~$32,000. One-time $250 out-of-state titling fee applies. Property tax in Charleston area ~0.65% of value.
One-time out-of-state titling fee: $250.00 Title and registration card (est.): $18.00 First SC biennial reg ($40 + $120): $160.00 ────────────────────────────────────────── Upfront (no new IMF on transfer): $428.00 Annual recurring: Property tax ($32k × 0.65%): $208.00 Reg + EV (annualized): $80.00 Electricity (10,000 mi, 3.2 mi/kWh at $0.151/kWh Dominion): $521.00 ────────────────────────────────────────── Annual total recurring: $809.00 Note: No IMF on transfer if already titled; EV fee still applies at SC registration
Moving an EV into South Carolina triggers the $250 titling fee in defined situations but does not re-impose IMF if the vehicle was previously titled elsewhere. The $120 biennial EV surcharge still applies at first South Carolina registration.

Common Questions
How often do I pay the $120 EV fee?
Every two years at registration renewal (or at initial titling for the first period). That averages $60 per year for a BEV.
Is the IMF the same as sales tax?
IMF is a separate 5% fee capped at $500 on many vehicle purchases. When IMF applies, traditional sales tax often does not. High-value deals and specific transaction types may differ—ask your dealer or county.
Do plug-in hybrids pay $120 or $60?
$60 biennial under the hybrid/combination-power definition. Full battery-electric and fuel-cell vehicles pay $120.
Is there a South Carolina EV purchase rebate in 2026?
No state purchase rebate or tax credit for buying an EV. Utility charger rebates and TOU rates may still help.
Can I still get the federal EV tax credit?
Generally not for vehicles acquired after September 30, 2025. Home charger credit may apply for qualifying installs through June 30, 2026.
Will the EV fee increase?
S.B. 831 (2025) proposed a much higher fee but did not pass as of 2026. Watch the General Assembly for updates.
How does county property tax work?
Each county sets millage on your vehicle’s assessed value. Use your county auditor’s online estimator for the best number.
Does a standard Toyota Prius pay the hybrid fee?
Yes. Non-plug hybrids that use both gasoline and electricity (through regenerative braking and hybrid drive) fall under the $60 biennial hybrid fee in S.C. Code §56-3-645. Only vehicles powered exclusively by electricity or hydrogen pay the $120 amount.
What standard DMV fees apply beyond registration?
Expect about $15 for a new title, $3 for a registration card, and the $1 annual SCDMV fee. Personalized or specialty plates add $40 to $160 biennially depending on plate type. These apply to all vehicle types, not just EVs.
How do I estimate break-even vs. a gas car?
Compare total cost of ownership over your planned ownership period. EVs often save $600 to $800 per year on fuel versus a 30 mpg gasoline car at $3.50 per gallon, but higher purchase price, IMF, and the $60-per-year annualized BEV fee can delay break-even. Without federal purchase credits in 2026, break-even may take five years or more unless the EV purchase price is close to the gas alternative.
Does South Carolina tax public charging?
Public charging networks set their own per-kWh or per-minute rates. South Carolina does not add a separate state tax on EV charging sessions beyond normal sales tax on the charging service where applicable. Home charging uses your residential utility rate.
Where the Numbers Come From
EV and hybrid biennial fees come from S.C. Code §56-3-645 and SCDMV collection rules under Act 3516 and Act 70. IMF amounts follow §56-3-627. Weight-based registration follows SCDMV published schedules. Property tax rates come from county auditors and treasurers. Electricity averages use EIA May 2026 data; utility-specific figures use Duke, Dominion, and Santee Cooper tariff materials. Federal credit dates follow IRS guidance on §30D and §30C.
Update calculator defaults when the Legislature changes EV fees, when SCDMV revises weight brackets, when counties adjust millage, or when utilities file new rate cases. Refresh IMF cap ($500) only if statute changes.
For accuracy, pull property tax from the buyer’s county estimator rather than a statewide guess. Hard-code biennial fees as $120 / $60 until law changes. Gasoline price defaults should reflect regional South Carolina pump prices—AAA and EIA publish state-level averages that typically run $3.20 to $3.80 per gallon in 2026 planning scenarios.
EV efficiency defaults of 3.0 to 3.5 miles per kWh suit most modern battery-electric sedans and crossovers. Larger electric trucks may achieve 2.0 to 2.5 mi/kWh; efficient compact models may exceed 4.0 mi/kWh. Let users override efficiency when they know their vehicle’s EPA rating or real-world average from the dashboard.
Maintenance costs are outside the scope of most registration-and-fuel calculators, but EVs generally require less routine maintenance (no oil changes, fewer brake replacements due to regenerative braking). That advantage is not modeled here but can tilt long-term ownership economics further toward EVs beyond what fuel savings alone show.

Key Takeaways for South Carolina EV Owners
South Carolina EV costs combine a $120 biennial BEV fee (or $60 for hybrids/PHEVs), weight-based biennial registration, IMF up to $500 at titling, and annual county property tax. There is no per-mile road charge—the flat biennial fee is the main EV-specific line.
Electricity is a relative strength: about 16 cents per kWh statewide, with off-peak programs often lower. At 12,000 miles and 3.5 mi/kWh, home charging often costs $550 to $650 per year versus $1,400 or more for gasoline at 30 mpg and $3.50 per gallon. The annualized $60 BEV fee is small compared with that fuel gap but matters for low-mileage drivers.
No state purchase incentive and no federal purchase credit on most 2026 buys mean upfront price and county tax drive the budget. Use your county estimator, utility TOU plan, and actual weight class in any calculator.
Monitor Columbia for fee legislation—2025 proposals would have raised BEV fees sharply if enacted. Until then, $120 every two years remains the statutory amount.
