How to Use the EV Cost Calculator

1 Enter the EV efficiency (miles per kWh) and your electricity rate.
2 Enter the EV purchase price.
3 Enter gas vehicle MPG, gas price, and purchase price for comparison.
4 Set your annual driving miles and ownership period.
5 Click Compare Costs to see the full breakdown.

The EV Cost Calculator compares total ownership costs between electric and gas vehicles, including purchase price and fuel costs. EV fuel cost is calculated as electricity price divided by efficiency (miles/kWh). Gas fuel cost is gas price divided by MPG. The tool shows cost per mile, annual fuel costs, and total savings over your ownership period.

The average EV gets about 3-4 miles per kWh, and the average US electricity rate is ~$0.13/kWh, resulting in about $0.03-0.04 per mile. The average gas car at 28 MPG with $3.50/gallon gas costs about $0.125 per mile — roughly 3x more expensive to fuel. EVs also have lower maintenance costs (no oil changes, fewer brake replacements).
