Use current energy assumptions
Enter gasoline cost per mile and EV electricity cost per mile from your actual efficiency and price. A fuel snapshot can provide context, but your home-charging, public-charging, or regional price may differ.
Review /guides/driver-vehicle-costs/ for EIA snapshot timing and the difference between default and user-edited price.
Include the fixed difference
A purchase premium, financing difference, or annual fixed-cost difference can delay the break-even point even when EV energy cost is lower.
The calculator shows annual scenario totals and returns null when the per-mile difference cannot produce a break-even.
Treat incentives and eligibility separately
Vehicle cost per mile gives a detailed cash-cost ledger. Tax incentives or loan-interest eligibility are not assumed here; check the separate eligibility tool and current rules.
Frequently asked questions
Does this include an EV tax credit?
No. Incentives depend on vehicle and taxpayer facts and are not automatically included.
Is electricity always cheaper than gas?
Not necessarily. Enter your actual efficiency and prices; the model reports whichever scenario is lower.
What is break-even miles?
It is the mileage needed for per-mile savings to recover the entered fixed-cost difference, when a positive difference exists.
