# Quick Answer: How To Work Out Fuel Costs For A Journey?

## Mileage Calculator | RAC Fuel Cost Calculator

The new RAC Fuel Cost and Mileage Calculator can help you calculate how much a journey will cost you in terms of fuel, as well as a fuel calculator that allows drivers to calculate their fuel consumption, with the overall driving distance displayed in miles and kilometres.

### RAC Fuel Watch

Fuel Watch is an RAC initiative that tracks petrol and diesel prices. We use our fuel price calculator to track wholesale and retail fuel prices every day, and we use this information to lobby retailers to pass on savings from lower wholesale prices to consumers at the pumps.

## How do you calculate fuel cost per km?

To calculate the litres per 100 km, multiply the number of kilometers by 100, then divide the number of litres by this number, for example, 450/100 equals 4.5, then divide 50 by 4.5 to get 11.11.

## What is the formula to calculate fuel consumption?

## How do you calculate fuel consumption per hour?

Method that is simple

1. Gallon Per Hour (GPH) = (specific fuel consumption x HP)/Fuel Specific Weight.
2. 300-hp Diesel Engine Example. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH.
3. 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH.

## How do you calculate fuel cost per mile?

To calculate annual fuel cost per mile, divide total actual or estimated fuel expenses by actual or estimated annual miles driven. For example, if you drove 15,000 miles last year and spent \$1,600 on gas, your fuel cost is 1,600 divided by 15,000, or 10.67 cents per mile.
