EV vs Gas Total Cost of Ownership Calculator

How this calculator works

This tool uses standard deterministic formulas to produce your result. Every input you enter is shown in the calculation so you can verify the math and adjust any assumption.

• Inputs: all numeric, with helpful defaults based on current national averages.
• Math: deterministic — the same inputs always produce the same output.
• Output: a clear number you can act on, plus supporting breakdown.

All defaults come from the GetAutoCalcs reference data file, reviewed quarterly. You should override every default with your actual number for the most accurate result.

EV vs Gas Total Cost of Ownership Calculator

Compare the true 5-year cost of owning an EV vs a comparable gas car.

Why this matters

Most auto-finance and EV decisions hinge on a handful of numbers — interest rate, loan term, annual mileage, fuel price, purchase price. Small changes to any of these can shift your total cost by thousands of dollars. A good calculator makes the tradeoffs visible so you can decide with confidence.

Tips for getting the most accurate estimate

• Use your actual numbers. Defaults are a national average, not your reality. Your quoted APR, your electric rate, your actual MPG — these matter more than any benchmark.
• Compare scenarios. The real value of a calculator is comparing options: a longer vs shorter loan term, putting more money down, or pricing an EV vs a gas equivalent. Run the numbers twice with different inputs.
• Check the methodology. Every calculator on this site shows its formula. If the number surprises you, verify it against the math.

What this calculator does not cover

These estimates are a starting point, not a commitment. Actual offers from a dealer, lender, or utility will depend on your specific credit profile, location, and timing. Registration and title fees, dealer documentation fees, and extended warranty costs are generally excluded unless noted.
