Fuel Cost Calculator

Formula & Calculation Methodology

Fuel Litres Needed = Distance (km) / Vehicle Mileage (km/l) | Total Fuel Cost = Litres Needed × Fuel Price per Litre

	ext{Litres} = rac{D}{M}, quad 	ext{Total Cost} = 	ext{Litres} 	imes P

Step-by-Step Worked Example

Trip Distance: 450 km | Vehicle Mileage: 15 km/l | Petrol Price: ₹96.50/Litre | Passengers: 3

1. Fuel Litres Required = 450 / 15 = 30 Litres
2. Total Trip Fuel Expense = 30 Litres × ₹96.50 = ₹2,895
3. Per Person Share = ₹2,895 / 3 Passengers = ₹965 per person

What is a Fuel Cost Calculator?

A Fuel Cost Calculator is a practical trip planning tool that calculates how much money you will spend on petrol, diesel, or CNG for a vehicle road trip. It also allows groups of travelers to split fuel costs fairly among passengers.

How Fuel Cost is Calculated

Calculating trip fuel cost requires three inputs:

1. Total One-Way or Round-Trip Distance in kilometers (km).

2. Vehicle Mileage / Fuel Efficiency in kilometers per litre (km/l).

3. Current Fuel Price per litre in Rupees (₹).

Trip Cost Formula

• Fuel Needed (Litres) = Distance (km) / Mileage (km/l)
• Total Fuel Cost (₹) = Fuel Needed × Fuel Price per Litre
• Cost Per Passenger (₹) = Total Fuel Cost / Number of Passengers

Example Fuel Calculation

For a 450 km road trip in a car giving 15 km/l mileage with petrol at ₹96.50/litre for 3 friends:

1. Fuel Consumption = 450 / 15 = 30 Litres

2. Total Expense = 30 × 96.50 = ₹2,895

3. Cost Per Person = ₹2,895 / 3 = ₹965

Ways to Estimate Fuel Cost

Factoring in city driving conditions vs highway driving, continuous AC usage (which reduces mileage by ~10%), and toll charges provides the most accurate overall trip budget.
