EV cost per mile = Electricity Rate ÷ Miles-per-kWh. Gas cost per mile = Gas Price ÷ MPG. EVs typically save $800–$2,000/year.
At $0.15/kWh and 3.5 mi/kWh: cost is $0.043/mile. Gas at $3.50/30mpg: $0.117/mile.
Over 5 years at 12,000 miles/year: potential savings of $4,000–$8,000+.
This tool is most appropriate for students, researchers, and practitioners who need a quick, accurate result without manual derivation. The formula and constants used are shown alongside the result for verification.
The most common error is using constants or conversion factors at the wrong precision. Physical constants should be used at their full defined precision in scientific calculations — intermediate rounding introduces errors that grow with each subsequent step.
A chemistry student calculates the molarity of a prepared solution from the mass of solute and volume of solvent. The calculator applies the formula with the correct molar mass and produces a result in mol/L — formatted for direct use in subsequent equilibrium or stoichiometry calculations.
At $0.15/kWh, a 75 kWh battery costs ~
Typically $800–$2,000/year on fuel alone, depending on local electricity rates, gas prices, and mileage.
