Electric Car Charging Calculator

What is the Electric Car Charging Calculator – Charging Cost?

The electric car charging calculator calculates the charging cost at home or at a public fast charging station and compares the cost to the equivalent gasoline cost.

The calculator is free, works directly in the browser, and does not require registration. All figures are based on standard formulas; always check the rules that apply where you live.

Calculation Principle

Charging Cost = Charged Energy (kWh) × Price ($/kWh). Charging Time = Battery Capacity (kWh) × (1-SOC) ÷ Charging Power (kW)

Fill in the fields of the calculator with your information and press the calculate button – the result will be displayed immediately. Try different values to compare options.

Practical Example

Battery 75 kWh, empty → full, home socket 11 kW, electricity $0.15/kWh → charging time 6.8 h, cost $11.25. The same trip with gasoline: 75 kWh ÷ 7 l ≈ 107 km ÷ 100 × 7 × 1.85 = $13.9.

Enter your own numbers into the calculator to get a personalized result. The calculator is designed for quick use in everyday situations.

When do you need this calculator?

The calculator is needed to support decision-making, budgeting, and cost comparisons. Getting accurate references quickly makes everyday life easier.

The result is an estimate – for important financial or construction decisions, we recommend consulting a professional.

Tips

• Generally charge at night during the cheaper night electricity tariff.
• Keep the battery charge between 20–80% for longevity; full charge only for long trips.
• Check with your home insurance if it covers damage related to electric car charging.
