What this calculator estimates
Compare annual gasoline and electric-vehicle energy costs for the same driving distance. The calculation runs locally in your browser and is intended for planning and comparison.
How to use it
Enter the requested values, select Calculate, review the headline result and supporting figures, then change one input at a time to compare another scenario.
How the calculation works
Gas cost is annual miles divided by MPG times gas price. EV cost is annual miles times kWh per 100 miles times the electricity rate.
Input checklist
The Gas vs Electric Car Cost Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.
- Annual miles driven: verify that this value uses the unit, period, and definition shown by the calculator.
- Gas vehicle fuel economy (MPG): verify that this value uses the unit, period, and definition shown by the calculator.
- Gas price per gallon ($): verify that this value uses the unit, period, and definition shown by the calculator.
- EV energy use (kWh per 100 miles): verify that this value uses the unit, period, and definition shown by the calculator.
- Electricity price per kWh ($): verify that this value uses the unit, period, and definition shown by the calculator.
Practical interpretation
Use the Gas vs Electric Car Cost Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: Gas cost is annual miles divided by MPG times gas price. EV cost is annual miles times kWh per 100 miles times the electricity rate. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.
Checks before relying on the result
Actual project prices vary with location, labor rates, material grade, site conditions, permits, waste, contractor pricing, and scope changes. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.
Important limitations
Vehicle price, charging losses, maintenance, insurance, taxes and changing energy prices are excluded.
