EV vs Gas Calculator Formula and Mathematical Explanation
The core of an EV vs Gas Calculator lies in comparing the total cost of ownership for each vehicle type over a defined period. This involves calculating initial costs, ongoing operational costs, and factoring in depreciation and incentives.
Step-by-Step Derivation:
The total cost of ownership for each vehicle is calculated as follows:
1. Annual Fuel Cost:
- Gas Car Annual Fuel Cost:
(Annual Miles Driven / Gas Car MPG) * Gas Price per Gallon - EV Annual Fuel Cost:
(Annual Miles Driven / EV Efficiency (miles/kWh)) * Electricity Cost per kWh
2. Annual Operating Cost (excluding fuel):
- Gas Car Annual Operating Cost:
Gas Car Maintenance Cost per Year + Gas Car Insurance Cost per Year - EV Annual Operating Cost:
EV Maintenance Cost per Year + EV Insurance Cost per Year
3. Total Annual Cost:
- Gas Car Total Annual Cost:
Gas Car Annual Fuel Cost + Gas Car Annual Operating Cost - EV Total Annual Cost:
EV Annual Fuel Cost + EV Annual Operating Cost
4. Total Ownership Cost (over ‘Years of Ownership’):
- Gas Car Total Ownership Cost:
(Gas Car Purchase Price + (Gas Car Total Annual Cost * Years of Ownership)) - (Gas Car Purchase Price * (Gas Car Resale Value % / 100)) - EV Total Ownership Cost:
(EV Purchase Price + EV Charger Installation Cost + (EV Total Annual Cost * Years of Ownership) - Federal EV Tax Credit - State/Local EV Incentives) - (EV Purchase Price * (EV Resale Value % / 100))
5. Total Savings/Cost Difference:
- Savings with EV:
Gas Car Total Ownership Cost - EV Total Ownership Cost - A positive value indicates savings with an EV, while a negative value indicates the gas car is cheaper.

Key Factors That Affect EV vs Gas Calculator Results
The outcome of an EV vs Gas Calculator is highly sensitive to several variables. Understanding these factors is crucial for accurate comparisons and informed decision-making.
- Annual Mileage Driven: This is perhaps the most significant factor. Higher annual mileage amplifies the impact of fuel/electricity cost differences. If you drive a lot, the lower per-mile cost of electricity for an EV can lead to substantial savings over time, making the EV vs Gas Calculator lean heavily towards electric.
- Fuel and Electricity Costs: Fluctuations in gas prices and local electricity rates directly impact the operational costs. Regions with high gas prices and low electricity rates will favor EVs, while the opposite can make gas cars more competitive. The EV vs Gas Calculator relies on your current input for these, so keep them updated.
- Vehicle Purchase Price: EVs often have a higher upfront purchase price than comparable gas cars. This initial cost can be a significant barrier, especially for shorter ownership periods. The EV vs Gas Calculator helps determine if the long-term savings offset this initial premium.
- Government Incentives and Tax Credits: Federal, state, and local incentives for EVs (tax credits, rebates, HOV lane access) can drastically reduce the effective purchase price of an EV. These can turn a financially unfavorable EV comparison into a favorable one, highlighting the importance of including them in the EV vs Gas Calculator.
- Maintenance and Repair Costs: EVs generally have fewer moving parts (no engine, transmission, spark plugs, oil changes), leading to lower routine maintenance costs. However, specialized EV repairs or battery replacements can be expensive, though rare. Gas cars have more frequent and varied maintenance needs.
- Insurance Premiums: EV insurance can sometimes be higher due to the higher initial cost of the vehicle and specialized repair requirements. However, this varies widely by model, driver, and insurer. It’s essential to get actual quotes for both vehicle types for an accurate EV vs Gas Calculator comparison.
- Resale Value and Depreciation: How well a vehicle retains its value over time significantly impacts the total cost of ownership. Historically, gas cars had more predictable depreciation, but EV resale values are evolving rapidly. Factors like battery health and technological advancements can influence EV depreciation.
- Charger Installation Cost: For EVs, the cost of installing a Level 2 home charger can be a notable upfront expense. While public charging is an option, home charging is often more convenient and cost-effective. This one-time cost is factored into the EV vs Gas Calculator.
