How to work it out

  1. Turn the percentage into a decimal: 200 ÷ 100 = 2
  2. Multiply: 2 × 10 = 20
  3. Check: Work backwards: 20 ÷ 10 × 100 = 200%.

Another method. As a proportion of part to whole: 200/100 = part/10, so part = 200 × 10 ÷ 100 = 20. Both methods always give the same answer.

In a spreadsheet: =200%*10. 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 200% is more than 100%, the answer is bigger than 10: it is 2 times 10.

Mark-ups: pricing an item at 200% of its $10 cost means selling it for $20.

Adding and taking away 200%

Increasing 10 by 200% gives 30. These do not cancel out: raising 10 by 200% and then lowering the result by 200% ends at -30, because the second 200% is taken of a bigger number.
