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.**
