EV Charging Cost Calculator — measure your ev charging cost impact. Evidence-based formula with reduction tips.
Estimated range = Usable battery (kWh) × Real-world efficiency (miles/kWh)
Real-world efficiency = EPA efficiency × condition factor (0.70–1.05 depending on speed, temp, terrain)
Charging cost = Energy needed (kWh) × electricity rate ($/kWh)
Cost per mile = Electricity rate ($/kWh) / Efficiency (miles/kWh)
