How to work it out

  1. Turn the percentage into a decimal: 1000 ÷ 100 = 10
  2. Multiply: 10 × 30 = 300
  3. Check: Work backwards: 300 ÷ 30 × 100 = 1000%.

Another method. As a proportion of part to whole: 1000/100 = part/30, so part = 1000 × 30 ÷ 100 = 300. Both methods always give the same answer.

In a spreadsheet: =1000%*30. 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 30: it is 10 times 30.

Mark-ups: pricing an item at 1000% of its $30 cost means selling it for $300.

Adding and taking away 1000%

Increasing 30 by 1000% gives 330. These do not cancel out: raising 30 by 1000% and then lowering the result by 1000% ends at -2,970, because the second 1000% is taken of a bigger number.
