EV vs Gas Car Maintenance Cost Calculator
How does EV maintenance cost vs a gas car compare? Enter your annual mileage — this calculator annualizes both sides from illustrative per-mile assumptions ($0.10 for gas and $0.06 for EVs) and shows the 5-year gap.

Estimate basis & methodology
Estimate basis: cost figures are illustrative U.S. budgeting assumptions. A dated source table has not been verified for these ranges; they should not be treated as current national averages. Actual costs vary by vehicle, location and shop. Get a written quote before authorizing any repair.
How the estimate works: gas cars are modeled at ~$0.10/mile of maintenance (oil, brakes, fluids, filters) and EVs at ~$0.06/mile (tires, brakes, cabin filter) — the 40% gap follows from these model inputs and is not a guarantee for a particular vehicle. Tires are included on both sides.
Key figure
Model assumption: this comparison uses fixed per-mile rates. It does not calculate vehicle-specific brake or tire life; driving conditions, tires and service requirements can change the result.
Worked example (you can verify by hand)
Input: 12,000 miles/year.
- Gas: 12,000 × $0.10 = $1,200/yr → $6,000/5yr
- EV: 12,000 × $0.06 = $720/yr → $3,600/5yr
- Saving: $2,400
Expected output: EV saves about $2,400 over 5 years (estimate).
Limitations — what this cannot do
- Excludes fuel/charging, insurance and depreciation — maintenance only.
- The mileage-only model returns zero at zero miles and omits time-based service costs that can still apply.
- Out-of-warranty EV battery replacement is rare but very expensive; not modeled here.
- Your tire costs dominate the EV side — check your actual tire prices.
FAQ
Are EVs really cheaper to maintain?
This model assumes 40% lower per-mile maintenance for EVs. Actual costs depend on the vehicle, tires, repairs and driving conditions; compare the applicable service schedules and quotes.
What maintenance does an EV need?
Mostly tires, cabin air filter, brake fluid checks, and inspections. No oil, spark plugs, transmission fluid, or exhaust work.
Do EV brakes last longer?
Regenerative braking can reduce friction-brake use, but pad life and service needs depend on the vehicle and conditions. Follow the manufacturer's inspection guidance.
What about EV battery replacement cost?
Rare within warranty (typically 8yr/100k mi). Out of warranty it's $5,000–$20,000+ depending on pack — the one catastrophic cost EVs carry, offset by its rarity.
