How to work it out

  1. Turn the percentage into a decimal: 13 ÷ 100 = 0.13
  2. Multiply: 0.13 × 13 = 1.69
  3. Check: Work backwards: 1.69 ÷ 13 × 100 = 13%.

Another method. As a proportion of part to whole: 13/100 = part/13, so part = 13 × 13 ÷ 100 = 1.69. Both methods always give the same answer.

In a spreadsheet: =13%*13. 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

1.69 is the 13% share of 13. The remaining 87% is 11.31, and the two parts add back up to 13.

Discounts: 13% off an item priced $13 saves $1.69, so you pay $11.31.

Adding and taking away 13%

Increasing 13 by 13% gives 14.69 and decreasing it by 13% gives 11.31. These do not cancel out: raising 13 by 13% and then lowering the result by 13% ends at 12.7803, because the second 13% is taken of a bigger number.
