How to work it out

  1. Divide the part by the whole: 13 ÷ 8 = 1.625
  2. Multiply by 100: 1.625 × 100 = 162.5%
  3. Check: Work backwards: 162.5% of 8 is 1.625 × 8 = 13.

Another method. As a proportion of part to whole: 13/8 = p/100, so p = 13 × 100 ÷ 8 = 162.5%. Both methods always give the same answer.

In a spreadsheet: =13/8*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

13 is more than the whole amount (1.625 times as much) of 8. 13 goes past 8 by 5, which is another 62.5% on top of the whole.

Targets: selling 13 items against a target of 8 means reaching 162.5% of the target, beating it by 62.5%.

Turning it around

If you know that 13 is 162.5% of a number, you can get that number back: 13 ÷ 1.625 = 8. And 8 as a percentage of 13 is 61.5385%, a different answer, because the whole has changed.
