Electric Car Break Even Calculator

Reviewed by Calculator Editorial Team

Determine when your electric car will pay for itself by comparing the total cost of ownership over time. This calculator helps you understand the financial break-even point by accounting for upfront costs, fuel savings, and other expenses.

How the Break Even Calculator Works

The electric car break even calculator estimates when your electric vehicle (EV) will pay for itself by comparing the total cost of ownership with a traditional gasoline car. The calculation considers:

  • Initial purchase price of the electric car
  • Cost of gasoline for a comparable car
  • Electricity cost for charging the EV
  • Annual maintenance costs for both vehicles
  • Depreciation of both vehicles

The calculator assumes you drive the same distance each year and compares the cumulative costs over time. The result shows how many years it will take for the EV to be financially equivalent to the gasoline car.

Key Assumptions

This calculator uses average US values for electricity costs, gasoline prices, and maintenance expenses. Actual results may vary based on your location, driving habits, and vehicle specifications.

Formula Used

The break even point is calculated using the following formula:

Break Even Formula

Break Even Years = (Initial Cost Difference) / (Annual Savings)

Where:

  • Initial Cost Difference = EV Purchase Price - Gasoline Car Purchase Price
  • Annual Savings = (Gasoline Cost per Year) - (Electricity Cost per Year) + (Maintenance Savings per Year)

The calculator then compares the cumulative costs of both vehicles over time to determine when the EV becomes the more economical choice.

Worked Example

Let's calculate the break even point for a scenario where:

  • Electric car purchase price: $35,000
  • Gasoline car purchase price: $25,000
  • Annual gasoline cost: $3,000
  • Annual electricity cost: $1,200
  • Annual maintenance savings (EV vs gasoline car): $200

Example Calculation

Initial Cost Difference = $35,000 - $25,000 = $10,000

Annual Savings = ($3,000 - $1,200) + $200 = $1,000

Break Even Years = $10,000 / $1,000 = 10 years

In this example, the electric car will pay for itself after approximately 10 years of ownership.

Year EV Cumulative Cost Gasoline Car Cumulative Cost
0 $35,000 $25,000
5 $35,000 + ($1,000 × 5) = $40,000 $25,000 + ($3,000 × 5) = $40,000
10 $35,000 + ($1,000 × 10) = $45,000 $25,000 + ($3,000 × 10) = $55,000

The table shows that at year 10, both vehicles have the same cumulative cost, marking the break even point.

Frequently Asked Questions

How accurate is the electric car break even calculator?
The calculator provides an estimate based on average values. Actual results may vary depending on your location, driving habits, and vehicle specifications.
Does this calculator account for tax incentives?
No, this calculator does not include federal, state, or local tax incentives. You may want to factor these into your calculations if you qualify for them.
What if I drive more miles per year?
The calculator assumes a standard annual mileage. If you drive more, you'll need to adjust the electricity and gasoline costs proportionally.
How often should I recalculate the break even point?
It's a good idea to review your calculations annually or when significant changes occur, such as price changes or new incentives.
