EV Savings Calculator
Estimate annual and five-year gas savings when switching from a gas or diesel vehicle to an EV.
Use this calculator to estimate how much money you could save by switching from a gas or diesel vehicle to an EV. Choose the EV you are considering, then adjust miles driven, current MPG, gas price, electricity rate, charging efficiency, and estimated maintenance costs.
Compare Gas vs. EV Driving Costs
Choose an EV, enter your current fuel economy and local energy prices, and estimate annual and five-year savings. Presets use approximate EPA-style efficiency figures, but every field is editable.
How to Use the Results
The annual savings estimate compares fuel plus basic maintenance assumptions. It does not include purchase price, insurance, registration, tires, financing, incentives, depreciation, or public fast-charging costs. Those items matter, but fuel and charging cost is usually the question shoppers want answered first.
Other Costs to Consider When Switching to an EV
Fuel savings are only one part of the ownership picture. EVs also tend to remove several maintenance items that gas and diesel owners are used to paying for, but they can add a few costs of their own.
Maintenance is usually simpler
Most EVs do not need oil changes, transmission fluid service, spark plugs, belts, exhaust work, or radiator flushes in the way many gas vehicles do. Common routine items are usually tire rotations, cabin air filters, wiper blades, washer fluid, and periodic inspections.
Brake pads often last longer
Regenerative braking and one-pedal driving can dramatically reduce normal brake-pad use. You still need the brake system inspected and serviced when required, but many EV owners see much longer brake-pad life than they did with gas vehicles.
Tires still matter
EVs are often heavy and make instant torque, so tire wear can be higher if you drive aggressively or skip rotations. Tire replacement is one of the main ongoing EV costs to keep in the budget.
Insurance can vary
Some EVs may carry higher insurance premiums because of purchase price, repair cost, parts availability, battery-related repair procedures, or performance. Always quote insurance before assuming the EV will be cheaper overall.
Why the EV Presets Are Estimates
EV efficiency changes with speed, weather, wheel size, terrain, tire choice, towing, and driving style. The built-in presets are practical starting points based on EPA-style kWh-per-mile ranges for common EVs. If you know your exact vehicle efficiency, choose custom and enter it directly.
Helpful Rule of Thumb
Most efficient Tesla models are often around 0.24 to 0.30 kWh per mile in mixed driving. Larger EVs and electric trucks can use much more energy, which is why a Cybertruck or Rivian will not have the same charging cost as a Model 3 or Model Y.
