Fuel Cost Calculator

Trip fuel cost from distance, mileage and fuel price.

Overview

Estimates total fuel consumption, trip gasoline costs, and per-passenger travel shares based on trip distance, fuel economy, and fuel price per liter.

Formula & Calculation Method

Fuel Consumed (Liters) = Distance (km) / Mileage (km/L) | Total Cost = Fuel Consumed × Fuel Price per Liter

Converts distance and vehicle fuel efficiency into total fuel liters and splits travel costs across carpool passengers.

Worked Example: 450 km Road Trip with 15 km/L Car Mileage at ₹102/L Petrol

Inputs: Distance = 450 km | Mileage = 15 km/L | Petrol Price = ₹102/Liter | Passengers = 3

  • Fuel liters consumed = 450 / 15 = 30.0 Liters
  • Total fuel cost = 30 Liters × ₹102 = ₹3,060
  • Per-passenger carpool split = ₹3,060 / 3 = ₹1,020 per person

Summary: Distance = 450 km | Fuel Used = 30 Liters | Total Cost = ₹3,060 | Cost per Person = ₹1,020

Common Use Cases

  • Road Trip Cost Sharing: Calculate fair fuel and toll expense splits among friends on weekend highway road trips.
  • Daily Commute Budgeting: Estimate monthly fuel expenditures for driving to work vs using public transit.
  • Fleet Expense Reimbursement: Submit accurate mileage reimbursement claims for business travel.

Frequently Asked Questions

How does air conditioning impact car mileage?

Running the vehicle AC in hot city traffic can reduce fuel economy by 5% to 15%.

How do I calculate my car's true real-world mileage?

Fill your tank full, reset the trip meter, drive normally, fill up full again, and divide trip kilometers by the liters pumped.

How do I convert MPG to km/L?

1 US MPG equals approximately 0.425 km/L (e.g. 30 MPG = 12.75 km/L).
