How to work it out

  1. Turn the percentage into a decimal: 1000 ÷ 100 = 10
  2. Multiply: 10 × 80 = 800
  3. Check: Work backwards: 800 ÷ 80 × 100 = 1000%.

Another method. As a proportion of part to whole: 1000/100 = part/80, so part = 1000 × 80 ÷ 100 = 800. Both methods always give the same answer.

In a spreadsheet: =1000%*80. 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 1000% is more than 100%, the answer is bigger than 80: it is 10 times 80.

Mark-ups: pricing an item at 1000% of its $80 cost means selling it for $800.

Adding and taking away 1000%

Increasing 80 by 1000% gives 880. These do not cancel out: raising 80 by 1000% and then lowering the result by 1000% ends at -7,920, because the second 1000% is taken of a bigger number.
