EV vs Gas Cost Calculator
How Much Does Your EV Actually Save?
See your real monthly and 5-year savings — fuel, maintenance and insurance included — using your state’s actual 2026 EIA electricity rate, current AAA gas prices, and the break-even year against the EV’s higher purchase price.

The Full Cost Picture. Not Just Fuel.
Most calculators compare fuel only. This one adds the two costs that decide your real monthly spend — maintenance and insurance — plus the upfront price gap.
What EV Buyers Actually Want to Know
At the national-average defaults — an $11,000 price gap, 12,000 mi/yr, $0.1805/kWh and $4.09/gal — payback lands around 9–11 years. It drops fast with higher mileage or cheap electricity (4–6 years in low-rate states) and stretches out where power is expensive, like Hawaii. Move the sliders for your own number.
For home charging, yes in nearly every state. At average rates an EV costs roughly $84/month less once you net out fuel, maintenance and the higher EV insurance. The advantage is largest where electricity is cheap and gas is pricey, and smallest in high-rate states. The big upfront price premium is separate — that’s what the break-even year above accounts for.
No. The federal EV credit (IRC §30D) ended for vehicles delivered after September 30, 2025 under the One Big Beautiful Bill Act. Some state programs remain — Colorado ($5,000), California up to $7,500 via CVRP, Oregon up to $7,500. Drop any rebate you qualify for into the EV Price slider above.
