EV Charging Cost Calculator (Home)

Estimate EV charging cost from battery size, charge added, electricity price, and charging efficiency.

FormulaCharging cost = battery kWh x charge added % x electricity rate / charging efficiency

Formula

EV charging cost estimate

This calculator is an independent planning estimate. Replace defaults with current local data before making financial, operational, or reporting decisions.

Charging cost = battery kWh x charge added % x electricity rate / charging efficiency

A 75 kWh battery charged from 20% to 80% at 0.16 per kWh costs about the entered energy plus charging-loss allowance.
