Total Cost of Ownership

Users can customize key variables to estimate costs and savings over time.

By adjusting these inputs, users can better understand the long-term financial impact of switching to an EV and identify the vehicle option that best fits their driving and budget needs.

Your Cost Settings

Your zip code determines regional fuel prices and which incentives you qualify for. Financing terms like loan length, rate, and down payment set your true monthly cost of ownership.

Vehicles

Your baseline vehicle is the benchmark and the clean vehicle is what you're weighing against it. We compare purchase price, fuel, and maintenance for each, so the savings are grounded in real numbers.
Notes:
  1. Vehicle Condition controls which Model Years are available: New shows the two most recent model years, while Used shows all available years.
  2. MSRP defaults to the base price for a brand-new vehicle of the selected model year. It does not account for depreciation or added options. If the actual purchase price differs, this field can be updated.
  3. Maintenance Rate is a per-mile cost covering routine manufacturer-recommended service, wear-and-tear repairs, and tires. The rate is derived from cost data averaged over 5 years and 75,000 miles, then applied to the specified annual mileage and lifetime. Total maintenance cost therefore scales with these inputs rather than a fixed mileage.
  4. Monthly Insurance Premium is optional and should reflect the current premium for the selected Baseline Vehicle.

Vehicle Usage & Lifecycle

Annual mileage and ownership duration are the biggest cost drivers in any TCO model. Every extra 5,000 miles a year can shift the lifetime total by thousands, so accuracy here pays off.

Infrastructure & Charger Configuration

Where and how you charge has a major impact on lifetime energy costs. Home Level 2 charging is typically 3 to 4 times cheaper than public DC fast charging, so the split between the two shapes your total.

Fuel & Energy Pricing

Accurate prices make your projection reliable. We've prefilled regional averages based on your zip code. Update them if you have a special utility rate or a better local estimate.
Note: Gas prices change often. The override toggle can be used to enter a current local price.

Incentives

Federal, state, and utility incentives can cut the net price of a clean vehicle by thousands. Including them shows your true cost advantage over the baseline.
