Work out how much each person pays when you share the cost of a trip in one vehicle. Enter the trip distance, the vehicle’s mileage, the fuel price you paid, any tolls or parking, and how many people are travelling. The calculator shows the fuel cost, the total cost and what each person pays, split equally among everyone or among passengers only.
You supply every figure. This tool does not suggest a fuel price, a mileage or an amount that is fair, and it gives no legal advice.
Use your own figures. This tool does not suggest a fuel price, a mileage or a wear amount, and it does not decide what is fair. Agree the split with the people travelling.

How to use the carpool cost split calculator
- Enter the trip distance in km, and choose one way or return. A return trip counts the distance twice.
- Enter the vehicle’s mileage in km per litre. Measure your own with our petrol cost and mileage calculator.
- Enter the fuel price per litre that you actually paid.
- Optionally add tolls, parking and other costs for the whole trip, and a wear and tear amount per km if the group agrees to include one.
- Enter the number of people travelling, including the driver, and choose whether everyone shares equally or only the passengers pay.
- Press “Split the cost”.
How the results are worked out
- Distance counted = trip distance, or twice that for a return trip
- Fuel cost = distance counted ÷ mileage × fuel price
- Wear and tear = distance counted × the amount per km you entered
- Total trip cost = fuel cost + wear and tear + tolls, parking and other costs
- Each person pays = total trip cost ÷ the number of people sharing (everyone, or passengers only)
Worked example (made-up numbers, not a recommendation)
Take a one-way trip of 250 km in a vehicle that does 12 km per litre, a fuel price of Rs. 280 per litre, Rs. 600 in tolls and 4 people.
- Fuel cost is about Rs. 5,833 and the total with tolls is about Rs. 6,433.
- Shared by all 4 people: each pays about Rs. 1,608.33, or Rs. 1,609 rounded up.
- Shared by the 3 passengers only: each pays about Rs. 2,144.44, or Rs. 2,145 rounded up.
These figures only show how the calculation works. They are not real prices or a suggested fare.
What this calculator does not include
- Vehicle wear, servicing, insurance, depreciation and fines, unless you add a wear amount yourself. See the full running cost with our vehicle ownership cost calculator.
- Changes in fuel price, traffic or the route during the trip, and extra stops.
- What is fair. The people travelling should agree the split among themselves.
- Any legal rule on carrying passengers for payment. This is a cost-sharing calculator only and gives no legal advice.
- Any fuel price, mileage or fare. We have not verified such figures for this page, so it shows none.

Carpool cost split calculator FAQs
How do I split fuel costs between passengers?
Work out the fuel for the whole trip by dividing the distance by the mileage and multiplying by the fuel price. Add tolls and parking, then divide by the number of people sharing. The calculator does this for you.
Should the driver pay a share?
That is for the group to agree. The calculator offers both options: everyone equally, or passengers only.
Should I add wear and tear?
It is optional. If the group agrees to include it, enter an amount per km that you have chosen. We do not suggest a value.
