EV vs Gas Savings Calculator: When Does an Electric Car Pay Off?

Will an electric car pay for itself in fuel savings? Enter your state, your car and how much more the EV costs to buy. At U.S. average prices, a Tesla Model Y charged at home saves about $1,133 a year against a 30-mpg gas car, so a $5,000 higher price pays back in roughly 4.4 years. Mixing in fast charging on road trips stretches that out, and this calculator shows by how much.

Tesla Model Y (27.5 kWh/100 mi), 100% home charging, 12,000 miles a year, 30-mpg gas car. EIA electricity (August 2026) and gas (week of October 12, 2026).

What this calculator leaves out

  • Maintenance: EVs skip oil changes, but tires can wear faster on heavy models.
  • Insurance and registration fees, which some states set higher for EVs.
  • Charger installation, typically $1,000 to $2,500 for Level 2 (our guide).
  • Resale value and battery health, which vary a lot by model.

Frequently asked questions

How long does it take for an EV to pay for itself?

At U.S. average prices and home charging, a Model Y saves about $1,133 a year on fuel versus a 30-mpg car, so a $5,000 premium takes about 4.4 years. It’s faster in cheap-power states and with longer commutes.

Does fast charging change the math?

A lot. Superchargers average $0.62 per kWh for non-members, over three times the home price, so drivers who mostly fast-charge can end up paying as much as for gas.

Is an EV cheaper than gas in every state?

With home charging, yes in nearly every state. The gap is smallest where electricity is expensive and gas is cheap.
