EV Savings Calculator

See total annual savings switching to an EV — fuel plus maintenance, not just charging cost.

This covers total annual savings (fuel + maintenance). Just need charging cost per mile? See the EV Charging Cost Calculator.

This tool provides a planning estimate based on the assumptions shown below the results — it is not a quote, and actual costs and savings will vary by installer, local rates, and your specific home.

How this calculator works

Fuel savings = (annual miles ÷ gas MPG × gas price) − (annual miles ÷ EV efficiency × electricity rate). Maintenance savings = annual miles × (gas maintenance cost/mile − EV maintenance cost/mile). Total savings combines both. This covers total cost of ownership savings — for charging cost alone, see our EV Charging Cost Calculator.
