How to calculate
Compare shared driving costs against per-traveler tickets and extras, then optionally value each traveler’s elapsed time.
Driving fuel=round-trip km×L/100 km÷100×price/L; ticketed cost=people×per-person costs+shared costs
Worked example
600 km at 7 L/100 km and 1.5/L costs 63 in fuel. With tolls 20 and parking 30, driving cash cost is 113. Two 150 tickets, 20 extras each and 40 shared transfer cost total 380.
Assumptions and input details
Use full round-trip distances, tickets, extras and elapsed hours consistently. Average speed and costs are your inputs, with no route, fare or live traffic service. Time value is a chosen scenario applied to every traveler. Existing car ownership, depreciation, accommodation, carbon costs and uncertain delays are excluded unless added to your entered costs.
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.
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.
Estimate ownership cost including purchase less resale, financing interest and entered annual running budgets.
Plan a sequence of entered distances, average speeds and breaks with dated arrival times.
