EV vs Gas: Which Costs Less?
Compare purchase price, incentives, fuel or charging, maintenance, and resale value over the years you expect to own the car.
Electric vehicle
Apply only incentives you expect to qualify for.
Gas vehicle
Use the same vehicle class for a fair comparison.
Driving
Ownership horizon often changes the winner.
About the EV vs Gas: Which Costs Less?
Electric and gas vehicles differ in almost every cost category — a higher typical purchase price for EVs offset by lower energy costs and often lower maintenance, plus incentives and resale value that can shift meaningfully by model and location. This calculator compares total ownership cost across purchase price, incentives, energy or fuel, maintenance, and resale value over the years you plan to own the vehicle, so the comparison reflects your actual driving pattern rather than a generic national average. It's useful whenever you're cross-shopping an EV against a comparable gas vehicle and want to know which one is actually cheaper to own over your specific ownership horizon and mileage.
How this calculator works
The recommendation is only as useful as its assumptions. Here is the exact framework used on this page.
Ownership cost = purchase price − eligible incentive + energy or fuel cost + maintenance − resale value. EV energy = miles ÷ miles per kWh × electricity price; gas fuel = miles ÷ MPG × gasoline price.
Calculation steps
- Energy use is calculated from annual miles and vehicle efficiency, then multiplied by local electricity or gasoline price and years owned.
- Purchase incentives reduce EV acquisition cost only when the user expects to qualify. Resale value offsets total ownership cost at the end of the horizon.
- Maintenance is entered directly because vehicle, warranty, climate, and local labor rates produce more variation than a single national assumption can capture.
Important assumptions
- Efficiency and energy prices remain constant unless the user enters a blended forecast.
- Insurance, financing, registration, and charger installation are excluded unless folded into another input.
- Resale values are nominal future estimates.
Frequently asked questions
Common questions about inputs, assumptions, and interpreting the result.
01How is EV charging cost calculated?+
Annual kWh equals annual miles divided by miles per kWh. That usage is multiplied by your blended electricity price and years owned. Use a price that reflects home, workplace, and public charging.
02Should charging losses be included?+
Yes when possible. Wall-to-battery losses mean purchased electricity can exceed energy stored in the battery. You can account for losses by using a slightly lower effective miles-per-kWh figure or a higher blended electricity price.
03How is gasoline cost calculated?+
Annual gallons equal annual miles divided by combined MPG. Gallons are multiplied by the expected average gasoline price and ownership years.
04Can I automatically claim the EV tax credit?+
No. Vehicle, price, battery sourcing, dealer reporting, income, ownership, and placed-in-service rules can affect eligibility. Enter only the incentive you have verified for the specific purchase.
05What expenses are not included?+
The current comparison excludes financing, insurance, registration, taxes, home-charger installation, and repairs beyond the annual maintenance inputs. Add material differences to purchase price or maintenance before relying on the result.
06How should I estimate resale value?+
Use current forecasts conservatively and test a low-resale scenario. Battery condition, incentives for new vehicles, technology changes, mileage, and used-vehicle demand can materially affect EV and gas resale values.
07Why does ownership horizon matter so much?+
An EV may have a higher net purchase price but lower energy and maintenance costs. More years and miles create more time for operating savings to recover the upfront premium.
08Does lower ownership cost mean lower environmental impact?+
Not necessarily. This tool measures dollars, not lifecycle emissions. Electricity generation, battery production, vehicle size, manufacturing, and driving patterns matter for environmental comparisons.
