How to calculate
Estimate trip or annual EV electricity spending with charging losses and fixed fees.
Battery kWh = distance × consumption ÷ 100; purchased kWh = battery kWh ÷ (efficiency/100); cost = purchased kWh × tariff + fees.
Worked example
Distance (km): trip or annual: 15000; Battery consumption (kWh/100 km): 18; Charging efficiency (%): 90; Price per kWh (your chosen currency): 0.25; Fixed/session fees in same currency: 0.
Battery energy: 2,700 kWh; Electricity purchased: 3,000 kWh; Charging loss: 300 kWh; Total electricity cost: 750 currency units.
Assumptions and limits
Estimate trip or annual EV electricity spending with charging losses and fixed fees. Use any currency consistently. Set efficiency to 100% when consumption is already measured at the wall. Public time-based fees must be entered as a total; charging tariffs are not fetched live.

Understanding the result
Estimate trip or annual EV electricity spending with charging losses and fixed fees. Use any currency consistently. Set efficiency to 100% when consumption is already measured at the wall. Public time-based fees must be entered as a total; charging tariffs are not fetched live.
When this tool is useful
Battery kWh = distance × consumption ÷ 100; purchased kWh = battery kWh ÷ (efficiency/100); cost = purchased kWh × tariff + fees.
Understanding your inputs
| Input | What to enter |
|---|---|
| Distance (km): trip or annual | Enter a number of at least 0 and no more than 1000000000000. |
| Battery consumption (kWh/100 km) | Enter a number of at least 0.000001 and no more than 1000000000000. |
| Charging efficiency (%) | Enter a number of at least 0.000001 and no more than 100. |
| Price per kWh (your chosen currency) | Enter a number of at least 0 and no more than 1000000000000. |
| Fixed/session fees in same currency | Enter a number of at least 0 and no more than 1000000000000. |
Frequently asked questions
Should I enter battery consumption or electricity measured at the wall?
Use battery consumption with the actual charging efficiency. If your consumption figure already includes wall losses, use 100% efficiency so those losses are not counted twice.
