Running Costs
EV Running Cost Calculator
Compute per-kilometer, monthly, and annual operational electricity expenses.
Primary Metric: Estimated Running Cost
Running Costs Deterministic Model v1.2
EV Cost Per Km Calculator
Calculate exact unit electricity expense per kilometer and per 100 km.
Unit Cost Inputs
Compute direct per-kilometer energy expenditure Cost Per Kilometer ₹0.98 ₹98.00 per 100 km
Energy Drawn per km: 0.140 kWh
Efficiency in km/kWh: 7.14 km/kWh
1,000 km Energy Cost: ₹980.00
At ₹0.98/km, driving 15,000 km annually requires under ₹15,000 in direct electricity expense.
Mathematical Formula & Physical Model
Converts efficiency into energy consumed per kilometer and multiplies by the local electricity tariff.
1
Energy per km (kWh) = 1 / Efficiency (km/kWh) 2
Cost per km = Energy per km (kWh) × Electricity Rate 3
Cost per 100 km = Cost per km × 100 Worked Example
Reference BenchmarkCity Electric Hatchback
An EV with an efficiency of 140 Wh/km (7.14 km/kWh) charged at a domestic tariff of ₹7.00/kWh.
Energy Consumption 140 Wh/km
Electricity Tariff ₹7.00 / kWh
Frequently Asked Questions
How do I convert Wh/km to km/kWh?
Divide 1,000 by the Wh/km figure. For example, 1000 ÷ 125 Wh/km = 8.0 km/kWh.
What is considered good EV efficiency?
Modern electric passenger cars typically achieve between 6.0 and 8.5 km/kWh (120–165 Wh/km) in urban driving.
