Frequently Asked Questions

How is EV payback calculated? ＋

Payback is estimated by dividing the EV price premium by the annual difference between gasoline spending and EV charging spending.

Are local gas prices included? ＋

The calculator uses editable gas and electricity price inputs. Use your local bill or current local fuel price for the most useful comparison.

Does battery degradation factor into savings? ＋

This calculator focuses on energy-cost savings and simple premium payback. Battery health, resale value, incentives, insurance, and maintenance can change the full ownership cost.

Methodology & Trust

How the EV savings estimate works

Gas cost is estimated from annual distance, gasoline efficiency, and fuel price. EV cost is estimated from annual distance, EV efficiency, home/public charging mix, and electricity prices.

Solar offsets reduce charging cost only as a planning assumption. Actual savings depend on net metering rules, charging time, battery storage, tariff design, and whether excess generation would otherwise be exported.

Payback is a simple energy-savings payback, not a complete ownership model. Add incentives, maintenance, financing, insurance, depreciation, and resale value before making a purchase decision.
