EV Calculators — Charging Cost, Range, Savings & More

Q: How accurate are these EV calculators?

Our calculators use real-world averages and industry data. Electricity rates default to the US national average ($0.14/kWh), gas prices to $3.50/gallon, and EV efficiency to 3.5 mi/kWh (the average for modern EVs). You can adjust all inputs to match your exact situation for precise results.

Q: What electricity rate should I use?

Check your utility bill for your per-kWh rate. The US national average is about $0.14/kWh, but rates vary widely — from $0.08/kWh in states like Louisiana to $0.30+/kWh in Hawaii and California. If you charge during off-peak hours, your rate may be even lower.

Q: Are these calculators specific to a particular EV model?

No — all calculators are model-agnostic. You input your specific vehicle's battery size (kWh), efficiency (mi/kWh), and other specs. This makes them work for any EV from a Nissan Leaf to a Tesla Model S to a Rivian R1T.

Q: How do I find my EV's efficiency in mi/kWh?

Check your vehicle's infotainment system for lifetime efficiency, or use the EPA rating. Common values: Tesla Model 3 = 4.0 mi/kWh, Chevy Bolt = 3.9, Ford Mustang Mach-E = 3.2, Rivian R1T = 2.5. Higher numbers mean better efficiency.
