How to work it out

  1. Turn the percentage into a decimal: 800 ÷ 100 = 8
  2. Multiply: 8 × 5 = 40
  3. Check: Work backwards: 40 ÷ 5 × 100 = 800%.

Another method. As a proportion of part to whole: 800/100 = part/5, so part = 800 × 5 ÷ 100 = 40. Both methods always give the same answer.

In a spreadsheet: =800%*5. 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 800% is more than 100%, the answer is bigger than 5: it is 8 times 5.

Mark-ups: pricing an item at 800% of its $5 cost means selling it for $40.

Adding and taking away 800%

Increasing 5 by 800% gives 45. These do not cancel out: raising 5 by 800% and then lowering the result by 800% ends at -315, because the second 800% is taken of a bigger number.
