How to work it out

  1. Divide the part by the whole: 500 ÷ 400 = 1.25
  2. Multiply by 100: 1.25 × 100 = 125%
  3. Check: Work backwards: 125% of 400 is 1.25 × 400 = 500.

Another method. As a proportion of part to whole: 500/400 = p/100, so p = 500 × 100 ÷ 400 = 125%. Both methods always give the same answer.

In a spreadsheet: =500/400*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.

What the result means

500 is more than the whole amount (1.25 times as much) of 400. 500 goes past 400 by 100, which is another 25% on top of the whole.

Targets: selling 500 items against a target of 400 means reaching 125% of the target, beating it by 25%.

Turning it around

If you know that 500 is 125% of a number, you can get that number back: 500 ÷ 1.25 = 400. And 400 as a percentage of 500 is 80%, a different answer, because the whole has changed.
