How to Compare EV vs Gas Costs

Enter your trip distance, your gas vehicle's MPG and fuel price, then your EV's efficiency (miles per kWh) and electricity rate. The calculator shows a side-by-side comparison and calculates your savings.

Average EV Efficiency

Most modern EVs get between 3-4 miles per kWh. Tesla Model 3 averages about 3.8 mi/kWh, while larger EVs like the Ford F-150 Lightning average around 2.1 mi/kWh. Check your vehicle's EPA rating for the most accurate number.

Electricity Rates

The US national average electricity rate is about $0.13/kWh, but rates vary widely — from $0.08/kWh in some states to over $0.25/kWh in others. If you charge during off-peak hours, your rate may be even lower.
