Overview

This calculator compares the multi-year total cost of ownership (TCO) of an electric vehicle (EV) versus a comparable internal combustion engine (ICE) vehicle. It accounts for purchase price, incentives, energy/fuel costs, maintenance, and resale value.

Use the fields to enter realistic prices and operating assumptions; results are estimates for planning and require adjustment to match your local incentives and driving patterns.

EV Purchase Price (before incentives)

Manufacturer MSRP or negotiated price before federal/local incentives. · Min 0 · Max 250000

EV Down Payment

Initial cash or trade-in applied at purchase. · Min 0 · Max 250000

Federal EV Tax Credit (or equivalent)

Enter the expected federal tax credit amount (if applicable). · Min 0 · Max 7500

Local Incentive / Rebate

State, city or utility rebates amount applied at purchase. · Min 0 · Max 20000

Annual Miles Driven

Typical miles driven per year. · Min 0 · Max 200000

Electricity Cost ($/kWh)

Average residential electricity price. Include off-peak charging rates if applicable. · Min 0 · Max 1

EV Efficiency (kWh per mile)

Vehicle energy consumption in kWh per mile (e.g., 0.25–0.35 kWh/mi). · Min 0.05 · Max 1

EV Annual Maintenance & Insurance ($/year)

Average yearly maintenance, insurance, and other operating costs beyond energy. · Min 0 · Max 20000

Comparable ICE Purchase Price

Purchase price for a comparable gasoline vehicle. · Min 0 · Max 250000

ICE Down Payment

Initial cash or trade-in for ICE vehicle. · Min 0 · Max 250000

Fuel Cost ($/gallon)

Average retail gasoline price per gallon. · Min 0 · Max 20

ICE Fuel Efficiency (mpg)

Miles per gallon for the selected ICE vehicle. · Min 1 · Max 200

ICE Annual Maintenance & Insurance ($/year)

Average yearly maintenance, insurance, and other operating costs for ICE vehicle. · Min 0 · Max 20000

Years Owned / Analysis Period

Length of ownership used to calculate multi-year costs. · Min 1 · Max 20

Estimated EV Resale Value After Period

Estimated vehicle trade-in or resale value at end of analysis period. · Min 0 · Max 300000

Estimated ICE Resale Value After Period

Estimated trade-in or resale value for the ICE vehicle. · Min 0 · Max 300000

How to read the result

What it means: The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
Next step: Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
Calculation limits: The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).

Methodology

Core formulas: annual energy cost for the EV = annual miles × EV efficiency (kWh/mile) × electricity cost ($/kWh).

Total ownership cost (EV) = upfront net purchase (price − incentives − down payment) + cumulative operating costs over the analysis period − resale value.

Total ownership cost (ICE) uses the same structure but substitutes fuel costs and ICE maintenance. All assumptions are user-editable.

Data sources and references are listed below; where possible we use government and agency data for typical ranges (EPA, U.S. DOE, state incentive databases). Users should verify current incentive amounts and local energy prices.

Glossary+

Total Cost of Ownership (TCO): The full lifecycle cost to own and operate a vehicle over a specified period, including purchase price, incentives, energy/fuel, maintenance, and resale.
Resale Value: Estimated value recovered when selling or trading in the vehicle at the end of the analysis period.
kWh per mile: Energy consumption metric for EVs, representing kilowatt-hours used to travel one mile.

Key takeaways

This tool provides a transparent, editable TCO comparison. It is intended for planning, not financial advice.

Review and update incentives, energy prices, and resale assumptions to reflect your local market before making decisions.

Worked examples

Commuter — Typical scenario (8 years)

An urban commuter drives 12,000 miles/year. Compare a $40k EV with a $35k ICE.

High mileage driver (12 years)

A long-distance driver covering 25,000 miles/year where fuel savings compound faster.

Short-term ownership (3 years) — resale sensitivity

When ownership period is short, resale value and upfront incentives dominate the result.

Frequently asked questions

What inputs matter most?

Key drivers are purchase price net of incentives, annual miles driven, electricity vs fuel cost, vehicle efficiency, and resale value. Adjust these to see sensitivity.

Are incentives and tax credits handled automatically?

No — incentives and tax credits vary widely. Enter the expected values in the designated fields. Consult official program pages to confirm eligibility and amounts.

Where do your assumptions come from?

Assumptions are drawn from public sources (EPA, U.S. DOE, state incentive databases) and peer-reviewed literature where available. See citations for links and verify local data.
