Find out how many miles you can get for £20 petrol in 2023! Just enter your vehicle’s MPG and petrol cost per litre into the calculator and you’ll get an estimate of how far you can get for £20 petrol.
How this calculator works
This calculator uses your vehicle’s fuel efficiency and the price per litre of petrol to calculate and estimate how many miles you can get from £20 petrol. Here’s how it works:
Step 1: We need to find out how many litres of petrol you will get for £20. This can be done using the formula: 20 ÷ petrol price in pence × 100.
For example, if the cost per litre of petrol is 165p, the formula would be: 20 ÷ 165 × 100 = 12.12 litres.
Step 2: The next step is to estimate how many miles you can get based on your car’s fuel efficiency (MPG). The formula to work this out is: MPG × litres × 0.22.
For example, if your car gets 40 MPG and you got 12.12 litres of petrol from £20, you can use this formula to estimate how many miles you can get: 40 × 12.12 × 0.22 = 106.67 miles.
