How to calculate
Normalize energy consumption and price bases, include explicitly entered charging loss and compare the same distance.
Gas cost=km×L/100km÷100×price/L; EV cost=km×Wh/km÷1000÷charging efficiency×price/kWh+fixed fee
Worked example
For 100 km, fuel use of 7 L/100 km at 1.5/L costs 10.5. Battery use of 180 Wh/km, 90% charging efficiency and electricity at 0.25/kWh cost 5. Gasoline cost minus EV cost is 5.5.
Assumptions and input details
EV consumption must use the battery-side basis; if your value already measures wall electricity, enter100%efficiency to avoid counting losses twice. All prices share one currency and are entered, without live tariffs or gasoline prices. This compares trip energy plus the entered charging fee, not purchase price, maintenance, charging availability, charging time or vehicle range.

Unit definitions
Unit selection is independent of language. Each selector contains only units for its physical quantity. Calculations use defined base units internally.
Choose from 23 length definitions, including explicitly labelled regional measures. Area conversions square the length factor; geometric volumes cube it.
Regional measures are not interchangeable merely because their names look similar. This is a documented selection, not a claim to include every historical unit.

Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Convert EV consumption and efficiency among Wh/km,kWh/100km,kWh/100miles,km/kWh and miles/kWh.
Estimate ownership cost including purchase less resale, financing interest and entered annual running budgets.
Estimate trip fuel and optional cost from distance, fuel economy and your own fuel price. Compare km/L, L/100 km, US mpg and Imperial mpg.
