How to Use Our Car Cost Calculator

Get a clear picture of your long-term expenses in just a few simple steps.

1. Enter Vehicle Details: Start by inputting the purchase price for both the gasoline and electric car you’re considering. Then, add the vehicle’s efficiency (MPG for gas, miles/kWh for EVs) and its estimated annual maintenance cost.
2. Set Your Driving Habits: In the “General Assumptions” section, tell us about your driving lifestyle. Enter your average annual mileage and how many years you plan to own the car. This is crucial for calculating long-term savings.
3. Input Local Costs: To ensure accuracy, provide the current price of gasoline ($/gallon) and the cost of electricity ($/kWh) in your area. You can typically find your electricity rate on your monthly utility bill.
4. Click “Calculate” and See Your Results: The calculator will instantly display the total cost of ownership for both vehicles over your chosen timeframe. An easy-to-read chart will also break down where your money goes, from the initial purchase to fuel and upkeep.

Understanding the Key Factors in Car Ownership Cost

What goes into your final result? Our calculator considers all the essential variables that determine the real-world cost of a car.

Purchase Price & Incentives

This is the most obvious cost, but it’s not always straightforward. While electric vehicles (EVs) can have a higher initial price tag, they often qualify for significant government incentives, like federal tax credits or state rebates. Our calculator accounts for these incentives, showing you the effective purchase price of the EV.

Fuel (Gas) vs. Energy (Electricity)

This is where the biggest long-term savings for EV owners typically come from.

• For Gas Cars: Your cost is determined by fuel efficiency (Miles Per Gallon) and the price of gasoline. Volatile gas prices can make budgeting unpredictable.
• For Electric Cars: Your cost is based on the car’s efficiency (miles per kilowatt-hour) and your local electricity rate. Charging at home, especially overnight during off-peak hours, is almost always significantly cheaper than filling up at the pump.

Maintenance and Repairs

Electric vehicles have far fewer moving parts than their gasoline counterparts. There are no oil changes, spark plugs, or exhaust systems to maintain. This results in demonstrably lower annual maintenance costs and fewer trips to the mechanic, a factor our calculator includes in its long-term projection.

Insurance Costs

Insurance premiums can differ between gas and electric models. Factors like the vehicle’s price, average repair costs, and safety features all play a role. We’ve included separate fields for insurance to give you the most accurate comparison possible.

Make Your Decision with Confidence

Choosing your next car is a major decision. By looking beyond the sticker price and understanding the complete financial picture, you can select the vehicle that best fits your budget, lifestyle, and long-term goals.
