EV vs Gas Cost Calculator
Compare annual driving costs for an electric vehicle and a gas car based on your driving habits.
In short
Enter your miles per year, gas price and MPG, electricity price and EV efficiency (kWh per 100 miles), plus maintenance guesses. We compute annual fuel or charging cost for each, add maintenance, and show which costs less per year and per month.
Use this calculator to estimate whether an EV or gas car costs less per year based on miles driven, fuel prices, efficiency, and maintenance.

How it works
We estimate yearly fuel cost for the gas car as miles divided by MPG times gas price. EV charging cost is miles divided by 100 times kWh per 100 miles times your electricity rate. We add the annual maintenance figures you enter for each side, then show totals, the maintenance difference alone, and how much the cheaper option costs per year and per month.
Common assumptions
Your real costs depend on driving mix, winter range, home vs public charging prices, and tires or brakes. Maintenance is highly variable; use dealer or insurer estimates if you have them. This is a simple annual snapshot, not a lease, loan, or total-cost-of-ownership comparison over many years.
FAQ
- Is an EV always cheaper than a gas car?
- Not always. It depends on mileage, electricity rates, gas prices, and maintenance assumptions. This calculator helps you compare for your situation.
- What does “annual maintenance comparison” mean?
- It is gas annual maintenance minus EV annual maintenance from your inputs. A positive number means you assumed higher yearly upkeep on the gas car than on the EV.
- How do I read the annual total cost difference?
- It is total annual cost for gas minus total for EV (energy plus maintenance). A positive value means the EV is cheaper for the year; a negative value means the gas car is cheaper.
- What is kWh per 100 miles?
- It’s how many kilowatt-hours of electricity the EV uses to drive 100 miles. Typical values are roughly 25–40 kWh per 100 miles depending on the vehicle.
