EV Charging Cost & Time Calculator
Know your charging time and cost before plugging in.
Energy = battery × (to − from) / 100. Time = energy / power. Cost = energy × price per kWh.
How it works
Energy = battery × (to − from) / 100. Time = energy / power. Cost = energy × price per kWh.
Worked example
60 kWh × (80−10)/100 = 42 kWh. At 7.4 kW → 5.7 h. At 0.30/kWh → 12.60.
Recommendations
- Home charging overnight is cheapest
- Use fast charging only when needed
- Charge to 80% at fast stations — the last 20% is slow
Tips & advice
- Precondition while plugged for a faster start
- Time home charging to off-peak rates
- Keep the charging cable dry and clean
