Transportation costs are one of the biggest monthly expenses for car owners. Whether you drive a traditional gasoline vehicle or a modern electric car, understanding how much you spend on energy each month is essential for budgeting and smarter decision-making.
Electric Vs Gas Car Calculator
This Electric vs Gas Car Calculator helps you instantly compare the monthly cost of driving a gasoline car versus an electric car based on your real-world inputs such as driving distance, fuel efficiency, fuel price, and electricity rate.
Instead of guessing which option is cheaper, this tool gives you a clear, data-based comparison so you can make informed financial decisions.
What Is an Electric vs Gas Car Cost Calculator?
An Electric vs Gas Car Cost Calculator is a simple financial comparison tool that estimates how much money you spend each month on:
- Gasoline consumption for a traditional car
- Electricity usage for an Electric vehicle
- Overall savings between both options
It uses real driving data like miles driven, MPG (miles per gallon), kWh per mile, gas prices, and electricity rates.
This makes it extremely useful for:
- Car buyers deciding between gas and electric
- Existing EV owners calculating savings
- Commuters planning monthly budgets
- Environmental cost comparison
How This Calculator Works
The calculator is based on two core energy cost models:
1. Gas Car Cost Model (Internal Combustion Engine)
Gasoline vehicles use fuel that is burned in an engine called an Internal Combustion Engine.
The cost depends on:
- Distance driven
- Fuel efficiency (MPG)
- Gas price per gallon
2. Electric Car Cost Model
Electric cars use electricity stored in batteries instead of fuel. Their cost depends on:
- Distance driven
- Energy efficiency (kWh per mile)
- Electricity price per kWh
Formulas Used in the Calculator
1. Gas Car Monthly Cost Formula
Step 1: Calculate fuel used
Gallons Used = Monthly Distance ÷ MPGStep 2: Calculate total cost
Gas Cost = Gallons Used × Gas Price per Gallon2. Electric Car Monthly Cost Formula
Step 1: Calculate electricity usage
Total kWh = Monthly Distance × kWh per mileStep 2: Calculate electricity cost
Electric Cost = Total kWh × Electricity Rate3. Monthly Savings Formula
Savings = Gas Cost − Electric Cost- If result is positive → Electric car saves money
- If result is negative → Gas car is cheaper
How to Use the Calculator (Step-by-Step Guide)
Using this tool is very simple and takes less than a minute.
Step 1: Enter Monthly Driving Distance
Input how many miles you drive in a typical month.
Example: 1,000 miles
Step 2: Enter Gas Car Fuel Efficiency (MPG)
Add your car’s average miles per gallon.
Example: 25 MPG
Step 3: Enter Gas Price per Gallon
Enter current fuel price in your area.
Example: $3.50 per gallon
Step 4: Enter Electric Car Efficiency
Add energy consumption of your EV in kWh per mile.
Example: 0.25 kWh/mile
Step 5: Enter Electricity Rate
Enter your electricity cost per kWh.
Example: $0.15 per kWh
Step 6: Click Calculate
The tool instantly shows:
- Gas car monthly cost
- Electric car monthly cost
- Monthly savings
Step 7: Reset (Optional)
You can reset inputs anytime to try different scenarios.
Example Calculation
Let’s understand with a real-world example:
- Monthly Distance: 1,200 miles
- Gas Efficiency: 30 MPG
- Gas Price: $3.80 per gallon
- EV Efficiency: 0.28 kWh/mile
- Electricity Rate: $0.16 per kWh
Gas Car Calculation
Gallons Used = 1200 ÷ 30 = 40 gallons
Gas Cost = 40 × 3.80 = $152Electric Car Calculation
Total kWh = 1200 × 0.28 = 336 kWh
Electric Cost = 336 × 0.16 = $53.76Savings
Savings = 152 − 53.76 = $98.24 per month👉 Electric vehicle saves nearly $100 per month
Comparison Table: Gas vs Electric Car Cost
| Factor | Gas Car | Electric Car |
|---|---|---|
| Energy Type | Gasoline | Electricity |
| Efficiency Unit | MPG | kWh/mile |
| Monthly Cost Dependence | Fuel price | Electricity rate |
| Maintenance Cost | Higher | Lower |
| Environmental Impact | Higher emissions | Lower emissions |
| Cost Stability | Highly variable | More stable |
