EV vs. Gas Savings & Break-Even Calculator

An electric car usually costs more to buy and less to run. This calculator works out both sides: the annual fuel-versus-electricity saving from your mileage and local prices, and the break-even year when that saving pays back the EV’s higher price.

One figure to get right: the federal clean-vehicle tax credit (up to $7,500 new, $4,000 used) ended for vehicles acquired after September 30, 2025, so the calculator defaults it to $0. Only state and utility incentives remain, and they vary — enter yours if you have them.

Standards & Sources

Last verified: November 2026

  • IRC §30D clean-vehicle credit — terminated

    The federal new- and used-EV tax credits ended for vehicles acquired after September 30, 2025. Only state and utility incentives remain, and they vary by location.

  • EPA fuel economy ratings

    MPG and miles-per-kWh figures are EPA combined estimates; real-world efficiency depends on climate and driving.

How to use this calculator

  1. Enter your annual mileage and your local gas price and electricity rate.
  2. Enter each car’s efficiency — MPG for the gas car, miles per kWh for the EV.
  3. Enter the price of each car and any state or utility incentive (the federal credit has ended).
  4. Read the annual savings, five-year savings, and the break-even year.

Frequently Asked Questions

Is an EV cheaper than a gas car?

Usually cheaper to run and often more expensive to buy. Whether it comes out ahead depends on your mileage, local electricity and gas prices, and the price gap — the calculator finds the break-even year.

Is there still a federal EV tax credit?

No. The federal clean-vehicle tax credit (up to $7,500 new and $4,000 used) ended for vehicles acquired after September 30, 2025. Only state and utility incentives remain, and they vary.

How much does it cost to charge an EV vs. buy gas?

At a typical home electricity rate, charging usually costs well under half of what the equivalent gasoline would — but public fast-charging can cost much more. The calculator uses the rate you enter.
