Calculator guide
Compare energy cost for the same annual driving distance. Use the explicitly labelled inputs below; rates, dimensions, and costs are assumptions, not live quotes.
Formula or method
Gas cost = annual miles ÷ MPG × gas price. EV cost = annual miles × kWh per mile × electricity rate. Savings = gas cost − EV cost.
How to use this calculator
- Set Annual Miles (miles). The interface starts with 12000; replace it with the value for your scenario.
- Set Gas Vehicle MPG (MPG). The interface starts with 28; replace it with the value for your scenario.
- Set Gas Price (per gallon). The interface starts with 3.50; replace it with the value for your scenario.
- Set EV Efficiency (kWh per mile). The interface starts with 0.30; replace it with the value for your scenario.
- Set Electricity Rate (per kWh). The interface starts with 0.16; replace it with the value for your scenario.
- Compare the result with the worked example, then vary one assumption at a time so you can see what changes.
Worked example
Enter Annual Miles = 12000 miles; Gas Vehicle MPG = 28 MPG; Gas Price = 3.50 per gallon; EV Efficiency = 0.30 kWh per mile; Electricity Rate = 0.16 per kWh. With those assumptions, the calculator gives Annual Gas Cost: $1,500.00; Annual EV Energy Cost: $576.00; EV Annual Savings: $924.00. These outputs are calculated from the same implementation as the interactive tool.
Understanding the result
In this example, Annual Gas Cost is $1,500.00. Annual EV Energy Cost is $576.00. Real-world schedules, fees, and local rules may differ from the assumptions entered in the tool.
Limitations and assumptions
- Real-world schedules, fees, and local rules may differ from the assumptions entered in the tool.
- The worked example demonstrates the stated assumptions, not a recommendation about your personal circumstances.
Frequently asked questions
Which inputs should I check first?
For Gas Vs EV Calculator, check Annual Miles, Gas Vehicle MPG, Gas Price, EV Efficiency, Electricity Rate. Keep the displayed units and select options consistent; do not treat default values as recommendations.
Why might my result differ from another tool?
Compare the other tool's gas vs ev calculator method, input units, rounding and assumptions. A matching title does not guarantee that both tools answer the same question.
Does a linked reference certify this result?
No. A reference can explain a formula or provide background for Gas Vs EV Calculator, but it does not endorse this website, validate personal inputs or establish professional suitability.
