EV Gas Savings Calculator

Thinking about switching to an electric vehicle? This EV Gas Savings Calculator helps you estimate how much money you could save on fuel by driving an EV instead of a traditional gas-powered car.

By comparing your monthly mileage, gas mileage, fuel prices, and EV energy efficiency, this tool gives you a clear picture of your potential monthly savings. Whether you’re curious, planning a purchase, or just comparing options — this is the perfect place to start.

How to Use This EV Gas Savings Calculator?

1. Enter Monthly Driving Distance

Input the number of miles you typically drive each month. This gives the calculator a basis to compare total fuel usage. You can use your average commute and weekend trips to estimate a realistic number.

2. Input Your Gas Vehicle’s MPG

Fill in the fuel economy of your current or typical gas-powered car in miles per gallon (MPG). If you’re unsure, look it up online based on your vehicle’s make and model.

3. Enter the Average Gas Price

Provide the current price per gallon of gasoline in your area. You can find this information at the pump or through fuel-tracking websites/apps.

4. Enter Your EV Electricity Rate

Input the cost per kilowatt-hour (kWh) that you pay for electricity. This can usually be found on your home electric bill or EV charging network’s app. If you’re estimating public charging, adjust the rate accordingly.

5. Enter EV Efficiency

Type in the average miles per kWh your EV can drive. Most electric vehicles average between 3 and 4 miles per kWh depending on driving conditions. You can use your EV’s EPA rating or real-world average.

6. Click “Calculate”

Press the button to instantly see your monthly cost comparison between a gas car and an EV — and how much money you could save each month just by switching to electric.

Frequently Asked Questions (FAQ)

What does this calculator compare?

This calculator compares the monthly cost of driving a gas vehicle versus an electric vehicle based on your inputs. It estimates how much fuel (gasoline or electricity) you’d use and multiplies that by the current fuel or electricity price to determine costs.

How accurate is the savings estimate?

The estimate is fairly accurate for basic monthly fuel cost comparisons, assuming typical driving habits. However, it doesn’t include factors like:

Charging losses (usually 10–15%)
Maintenance savings (EVs usually have fewer moving parts)
Seasonal efficiency changes
So it’s a conservative fuel-only estimate — real total savings may be even higher.

What is miles per kWh and how do I find it?

Miles per kilowatt-hour (mi/kWh) is a measure of how far your EV travels on one unit of electricity. You can find your car’s average from the dashboard or consult EPA ratings. Most EVs average between 3.0 and 4.0 mi/kWh, depending on driving style, speed, and climate.

What if I charge at free or discounted stations?

If you regularly use free charging (like workplace stations or public incentives), enter 0 for the electricity rate. If you get discounted off-peak charging, use that rate to get a more accurate estimate.

Can I use this calculator for yearly savings?

Absolutely! Just multiply your monthly savings result by 12 to get a rough estimate of annual savings. For example, saving $120/month = about $1,440/year.
