Why this page exists

EV-versus-gas comparisons become much easier to trust when both sides are reduced to the same monthly mileage and energy-cost frame. This calculator helps visitors compare estimated EV driving cost with gas driving cost and see the monthly difference under one simple set of assumptions.

EV vs gas cost calculator

Compare the estimated monthly driving cost of an electric vehicle with a gas vehicle.

$101

Estimated monthly savings from the EV side compared with the gas side under the assumptions entered.

Estimated EV driving cost$47

Estimated gas driving cost$148

Estimated monthly difference$101

Miles driven per month950

Driving about 950 miles per month at 29.0 kWh per 100 miles costs about $47 on the EV side.
A gas vehicle at 28.0 MPG and $4.35 per gallon costs about $148 over the same monthly mileage.
Under these assumptions, the EV side is cheaper by about $101 per month.

This is a planning estimate. Real driving cost can vary with weather, charging losses, traffic, driving style, maintenance, and local fuel or electricity pricing.

How it works

What the calculator is doing

Enter the miles driven per month.

Add the EV efficiency and electricity rate to estimate the electric side of the comparison.

Add gas MPG and gas price to estimate the gas side and compare the monthly difference.

Understanding your result

The monthly difference is the most practical output because it turns the EV-versus-gas idea into a recurring cost comparison instead of only a theory about efficiency.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Compare current gas driving with a possible EV

Use the same monthly mileage across both sides so the cost difference reflects the powertrain assumptions rather than a different driving pattern.

Stress-test fuel and electricity pricing

Adjusting both energy prices can help show whether the comparison still holds under different local conditions.

Use a commute-based monthly mileage estimate

This works well when you want a recurring transportation-cost comparison tied to a realistic monthly driving amount.

FAQ

Common questions

How is the EV side calculated?

This calculator uses monthly mileage, EV efficiency in kWh per 100 miles, and electricity rate per kWh to estimate electric driving cost.

How is the gas side calculated?

It divides monthly miles by gas MPG, then multiplies the gallons used by the gas price per gallon entered.

Does this include maintenance or insurance?

No. It focuses on direct driving-energy cost only, so maintenance, insurance, and financing are not part of this comparison.
