How it is calculated
- Annual energy = distance × consumption ÷ 100.
- Annual energy cost uses a weighted average of home and public charging prices, then adds the entered yearly fixed cost.

How to use this tool
- Enter yearly kilometres and a representative energy consumption.
- Add home and public prices, and the percentage of charging energy bought publicly.
- Enter annual insurance and service, select the display currency, and read the energy subtotal and annual budget separately.
Worked example
15,000 km with 20% public charging
- Annual distance
- 15000 km / year
- Consumption
- 18 kWh / 100 km
- Home electricity price
- 0.2 per kWh
- Public charging share
- 20 %
- Public charging price
- 0.42 per kWh
- Insurance + service
- 1800 per year
- Currency display
- US dollar ($)
Expected result About $2,459/year · energy $659 · about $205/month
Annual energy is 2,700 kWh. The blended rate is 0.8 × $0.20 + 0.2 × $0.42 = $0.244/kWh. Energy costs $658.80; adding $1,800 gives $2,458.80/year.

How to read this result
The headline includes insurance and service. The energy line is the charging-only subtotal. This is a running-cost budget, not a complete ownership cost or purchase recommendation.
Assumptions
- The public charging share is a share of energy, not a share of charging sessions.
What this estimate cannot tell you
- The result is not a full cost of ownership and excludes purchase price, financing, taxes, depreciation, and incentives.
