EV Savings Calculator

Fueling an electric vehicle costs a fraction of what you'd pay at the gas pump — the EV Savings Calculator shows you exactly how much you'd save by making the switch. Enter your weekday and weekend miles, your current car's MPG, and gas price per gallon, then add your EV efficiency and electricity rate to see your Annual Fuel Savings. Secondary outputs break down your annual gas cost vs. electric cost, cost per mile for each, and total annual miles driven.

Frequently Asked Questions

How accurate is this EV savings calculator?

The calculator provides a good estimate based on your inputs, but actual savings may vary depending on driving conditions, weather, charging habits, and specific vehicle efficiency. Use current local rates for the most accurate results.

What's the average miles per kWh for electric vehicles?

Most electric vehicles achieve between 3-4 miles per kWh. Compact EVs like the Tesla Model 3 can achieve 4+ mi/kWh, while larger SUVs typically get 2.5-3.5 mi/kWh.

Should I include charging losses in my calculation?

Charging losses (typically 10-15%) are already factored into the average efficiency ratings. However, DC fast charging can have higher losses than home charging.

How do I find my electricity rate?

Check your electric bill for the rate per kWh, or contact your utility company. Rates vary by location and can range from $0.08 to $0.30+ per kWh depending on your region.

Do electric vehicles really save money on fuel?

In most areas, yes. Electricity is generally cheaper per mile than gasoline, with typical savings of $500-2000+ annually depending on driving habits and local energy costs.

What about EV maintenance savings?

EVs have fewer moving parts and don't require oil changes, spark plugs, or transmission maintenance. This can save an additional $400-800 per year in maintenance costs.

How does time-of-use electricity pricing affect savings?

Many utilities offer lower rates during off-peak hours (typically overnight). Charging during these times can increase your savings significantly, sometimes reducing electricity costs by 30-50%.

Should I factor in the cost of a home charging station?

While this calculator focuses on fuel costs, a Level 2 home charger ($500-2000 installed) provides convenience and faster charging. Federal and local rebates often help offset installation costs.
