10-Year TCO Scoreboard: With the $7,500 Federal Credit Gone, a $42K EV Beats a $30K Gas Car by $750
We ran the full 10-year total cost of ownership for a representative pairing: a $42K EV vs a $30K gas car of similar size and feature set, both driven 15,000 miles/year for a decade. Here’s where the money actually goes.
The full TCO breakdown
| Cost category | Gas car | EV | EV advantage |
|---|---|---|---|
| Purchase price | $30,000 | $42,000 | −$12,000 |
| Fuel (10 yr × 150K mi) | $17,500 | $6,000 | +$11,500 |
| Maintenance | $6,000 | $3,000 | +$3,000 |
| Insurance | $15,000 | $18,750 | −$3,750 |
| Resale value at year 10 | −$6,500 | −$8,500 | +$2,000 |
| 10-year total cost | $62,000 | $61,250 | +$750 |
The headline: the EV wins by $750 over 10 years, well within the noise of any one person’s actual rates. Until September 30, 2025, a qualifying EV could also take the US federal clean vehicle credit of up to $7,500 (IRC Section 30D), which made it an $8,250 win. The IRS says that credit is not available for vehicles acquired after that date.
Where each line comes from
Purchase. The EV starts $12K above the gas car. The $7,500 federal credit used to cut that premium to $4,500; for an EV acquired after September 30, 2025, the full $12K gap stands unless a state program or the dealer closes some of it.
Fuel. Gas car at 30 MPG × $3.50/gal × 150,000 miles = $17,500. EV at 3.5 mi/kWh × $0.14/kWh × 150,000 miles = $6,000. The $11,500 savings is the EV’s biggest TCO advantage — and the input most sensitive to your specific situation.
If you charge primarily at home overnight: $0.10-$0.15/kWh, EV stays cheap. If you charge primarily at public DC fast chargers: $0.30-$0.45/kWh, fuel cost climbs to $13,000-$18,000 — gas car wins on fuel.
Maintenance. Gas car: oil changes ($1,500), brake pads/rotors ($1,800), spark plugs/belts ($700), transmission service ($300), miscellaneous (~$2,000) = ~$6,000-$7,000. EV: tires ($1,800), brake fluid ($200), cabin filters/wipers ($300), miscellaneous ($700) = ~$3,000.
The EV maintenance edge isn’t just about oil. Regenerative braking dramatically extends brake life. No transmission. Fewer fluids. Fewer moving parts.
Insurance. EVs cost 15-25% more to insure. Higher repair costs (specialized parts, fewer shops), higher replacement values, and limited shop networks all push premiums up. Over 10 years, $3,750 working against the EV.
Resale value. Both depreciate ~80% over 10 years. EV depreciation is more variable: Tesla holds value well, some older non-Tesla EVs depreciate faster than ICE due to rapid tech improvement making older models look obsolete.
Without the federal credit, it’s a coin flip
- EV TCO: $61,250
- Gas TCO: $62,000
The EV wins by $750 over 10 years, roughly $75 a year. That’s noise. Specific rates and habits flip this either direction.
The cases where the EV still wins clearly:
- High annual mileage (20K+ miles/year)
- Cheap home electricity ($0.10/kWh or below)
- Expensive gas ($4.50+/gallon)
The cases where gas wins:
- Low annual mileage (8K or less)
- Expensive electricity ($0.25+/kWh)
- Primary reliance on DC fast charging
- No home charging available
What changes the answer most
Annual mileage. The EV’s fuel-cost advantage scales linearly with miles. At 8K mi/year, the 10-year fuel savings drop to ~$6,000. At 25K mi/year, they grow to $19,000. Mileage is the single biggest swing factor.
Home vs DC fast charging. Home charging at $0.14/kWh: EV fuel cost $6,000 over 10 years. DC fast at $0.40/kWh: EV fuel cost $17,000. Same car, same miles. The infrastructure question is huge.
Incentives. The US federal credit of up to $7,500 ended for vehicles acquired after September 30, 2025. Some states still offer their own credits or rebates. Without any, EVs need either lower purchase prices or higher mileage to break even.
Electricity rate. National average $0.14/kWh. CA: $0.30+/kWh. WA + parts of TN: $0.10/kWh. Local variance can move the EV’s fuel cost by 2x.
Where this scenario doesn’t apply
- Used EVs. Different math entirely — depreciation already absorbed, but battery health and out-of-warranty repair risk are concerns. Worth analyzing separately.
- Heavy-duty or fleet use. Commercial trucks, vans with continuous use have different fuel/maintenance ratios.
- Cold climates. EV range drops 20-40% in extreme cold; this affects “real” miles per kWh and may require higher-capacity battery, raising the entry price.
- Apartment or street parking. No home charging access. Public charging dependency makes the EV case much weaker.
What to actually do
- Get specific gas + electricity rates for your area.
- Run the calculator with your actual annual mileage.
- Check whether your state still offers an EV credit or rebate; the federal one is gone.
- Check whether you can install home charging.
- If home charging is a no, run the math at DC fast charge prices before committing.
