The Real Financial Comparison Between Electric and Gas Vehicles in 2026

Last updated July 2, 2026

The federal EV tax credit of up to $7,500 that existed under the Inflation Reduction Act expired on September 30, 2025. Buyers who finalize vehicle purchases after that date cannot claim the credit on their 2026 tax returns, which changes the total-cost comparison between electric and gas vehicles significantly. At an average electricity rate of $0.17 per kWh and a typical EV efficiency of 3.5 miles per kWh, the cost to drive one mile electrically is approximately $0.049, compared to $0.155 per mile for a 25 MPG gas vehicle at $3.88 per gallon. The annual fuel cost difference for 15,000 miles is approximately $1,590 in favor of the EV.

The purchase price premium for EVs relative to comparable gas vehicles varies by model but generally runs $3,000 to $10,000 above the gas equivalent after the credits expired. At $1,590 in annual fuel savings and lower maintenance costs from fewer moving parts, no oil changes, and regenerative braking that extends brake life, the payback period on the price premium has extended compared to when the credit was available. For buyers in states with strong utility time-of-use rates who charge overnight at $0.08 to $0.10 per kWh, the per-mile cost drops significantly and the total-cost comparison improves considerably.

Modeling the EV versus gas comparison using your actual electricity rate, driving mileage, and the real price premium for comparable models without the federal credit. In many markets and use cases the EV still wins on total cost of ownership over a five to seven-year period, but the margin has narrowed. State incentives in California, Colorado, and New York partially offset the federal credit expiration for buyers who qualify.
