Trip Cost Calculator
Planning a road trip? This trip cost calculator adds up the real cost of the drive before you start: fuel from your car's mileage and the current fuel price, plus tolls, food, hotel stay and anything else — then splits the total per person and per kilometre. Enter the one-way distance, pick round trip if you are coming back the same way, and adjust the numbers to your own car and your own style of travelling.

How to use this trip cost calculator
- Enter the one-way distance from a map app, and choose round trip if you will drive back — the total distance doubles automatically.
- Enter your vehicle's real mileage (what you actually get on the highway, not the brochure figure) and today's fuel price in your city.
- Add tolls for the route, food per day, hotel cost per night, and an 'other' amount for tickets, parking and a safety buffer.
- Set the number of travellers to see the per-person split, and use the per-kilometre figure to compare with a train, bus or taxi.
How trip cost is calculated
Fuel is normally the biggest single cost, and the formula is simple: the car drinks one litre every few kilometres, so the litres you need are the distance divided by the mileage, and the cost is those litres multiplied by the price per litre. Everything else is honest addition — tolls, food by the day, rooms by the night — and the total is then divided by travellers and by kilometres to give the two figures that make comparisons easy.
Fuel cost = litres × price per litre · Total = fuel + tolls + (food × days) + (stay × nights) + other
Two things this calculator does not count, so you are not surprised: wear and tear on the car (tyres, oil, servicing — realistically ₹1–3 per kilometre on an owned car) and your own driving time. If you are comparing driving with a train fare for a solo trip, adding even ₹1 per kilometre of wear can change the answer; for a family of four sharing, the car usually still wins comfortably.
Worked example
A family of four drives from home to a hill station 425 km away and back — 850 km in all. The car gives 15 km per litre and petrol costs ₹105 a litre:
- Fuel needed = 850 ÷ 15 = 56.67 litres → fuel cost = 56.67 × ₹105 = ₹5,950
- Tolls and parking = ₹800
- Food = ₹1,200 × 3 days = ₹3,600
- Stay = ₹2,500 × 2 nights = ₹5,000
- Other = ₹1,000
- Total trip cost = ₹16,350 → ₹4,087.50 per person, about ₹19.24 per kilometre
These are the defaults in the calculator above, so you can check every figure yourself and then change them to your own route.
Fuel cost by distance (at 15 km/l and ₹105 per litre)
| Total distance | Fuel needed | Fuel cost |
|---|---|---|
| 100 km | 6.67 litres | ₹700 |
| 300 km | 20.00 litres | ₹2,100 |
| 500 km | 33.33 litres | ₹3,500 |
| 850 km | 56.67 litres | ₹5,950 |
| 1,000 km | 66.67 litres | ₹7,000 |
Fuel prices differ by state and city, and change often. Enter the price at the pump where you will actually fill up — a ₹3 per litre difference changes an 850 km trip by only about ₹170, but on a 3,000 km tour it adds up to real money.
Frequently asked questions
How is the fuel cost of a trip calculated?
Fuel cost = distance ÷ mileage × fuel price. For example, an 850 km trip in a car that gives 15 km per litre, with petrol at ₹105 a litre, needs 850 ÷ 15 = 56.67 litres, which costs 56.67 × ₹105 = ₹5,950. If you know your car's consumption in litres per 100 km instead, switch the fuel mode in the calculator and it uses distance × consumption ÷ 100 × price.
Should I enter one-way or return distance?
Enter the one-way distance and choose 'Round trip' — the calculator doubles it. The default example is a 425 km one-way drive done as a round trip, so the fuel is worked out on 850 km. If you are driving a loop or several legs, choose 'One way' and enter the full distance you will actually drive.
What costs do people usually forget on a road trip?
Tolls and parking are the classic ones, followed by the food stop that turns into a restaurant bill, a night halt you did not plan, and city driving at either end which burns more fuel than the highway. This calculator has fields for tolls, food per day, stay per night and an 'other' bucket — and it is wise to keep a 10% buffer in 'other' for the surprises.
How do I split the trip cost between friends?
Enter the number of travellers and the calculator shows the cost per person. Fuel, tolls, food and stay are usually shared equally, but agree the rule before you start: some groups split only fuel and tolls and let each person pay their own food. The per-kilometre figure helps when one person joins for only part of the route.
Why does the real fuel bill differ from the estimate?
Mileage is an average. Air-conditioning, hill roads, traffic jams, a full load and high speeds all reduce it — a car rated at 18 km/l may give 14–15 km/l on a loaded highway run. Use the mileage you actually observe on trips, not the company's claimed figure, and your estimate will be close.
Is it cheaper to drive or take a train for a long trip?
For one person, a train or bus is usually cheaper because the car's full fuel and toll cost falls on a single traveller. For four people sharing, driving often wins: in the default example the whole 850 km trip costs ₹16,350, which is ₹4,088 per person — compare that with four train fares plus autos and food at both ends, and do not forget the car's wear and tear, which this calculator does not count.
