What it is
The Department of Energy's Vehicle Cost Calculator (via the Alternative Fuels Data Center) compares total cost of ownership across ICE, hybrid, PHEV, and EV options. Enter your annual miles, fuel prices, electricity rates, and vehicle preferences. The tool models fuel costs, maintenance, insurance, financing, and federal/state incentives over a user-defined ownership period. Results show total cost of ownership and cumulative emissions for each option side by side.
Why we picked this
The DOE calculator is the original and most comprehensive vehicle cost comparison tool, which most commercial EV calculators wrap or simplify. It includes variables that simple 'gas vs electric' comparisons miss: maintenance cost differences (EVs have 40 to 50% lower maintenance), battery degradation, resale value projections, state-specific incentives, and time-of-use electricity rates. For households deciding between an EV, hybrid, and ICE replacement, this tool provides the most complete financial picture available from a neutral source.
Key takeaways
- EVs have 40 to 50% lower lifetime maintenance costs than ICE vehicles due to fewer moving parts: no oil changes, transmission service, or exhaust system repairs.
- The federal EV tax credit ($7,500 for qualifying vehicles through 2032) combined with state incentives can reduce the effective purchase price of an EV by $10,000 to $15,000.
- At average US electricity rates ($0.16/kWh), fueling an EV costs approximately $0.04 per mile, compared to $0.12 to $0.16 per mile for gasoline at $3.50 to $4.50 per gallon.
