How to work it out

  1. Turn the percentage into a decimal: 500 ÷ 100 = 5
  2. Multiply: 5 × 20 = 100
  3. Check: Work backwards: 100 ÷ 20 × 100 = 500%.

Another method. As a proportion of part to whole: 500/100 = part/20, so part = 500 × 20 ÷ 100 = 100. Both methods always give the same answer.

In a spreadsheet: =500%*20. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

Because 500% is more than 100%, the answer is bigger than 20: it is 5 times 20.

Mark-ups: pricing an item at 500% of its $20 cost means selling it for $100.

Adding and taking away 500%

Increasing 20 by 500% gives 120. These do not cancel out: raising 20 by 500% and then lowering the result by 500% ends at -480, because the second 500% is taken of a bigger number.
