How to work it out

  1. Turn the percentage into a decimal: 500 ÷ 100 = 5
  2. Multiply: 5 × 90 = 450
  3. Check: Work backwards: 450 ÷ 90 × 100 = 500%.

Another method. As a proportion of part to whole: 500/100 = part/90, so part = 500 × 90 ÷ 100 = 450. Both methods always give the same answer.

In a spreadsheet: =500%*90. 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 90: it is 5 times 90.

Mark-ups: pricing an item at 500% of its $90 cost means selling it for $450.

Adding and taking away 500%

Increasing 90 by 500% gives 540. These do not cancel out: raising 90 by 500% and then lowering the result by 500% ends at -2,160, because the second 500% is taken of a bigger number.
