How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 63 = 13.23
  3. Check: Work backwards: 13.23 ÷ 63 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/63, so part = 21 × 63 ÷ 100 = 13.23. Both methods always give the same answer.

In a spreadsheet: =21%*63. 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

13.23 is the 21% share of 63. The remaining 79% is 49.77, and the two parts add back up to 63.

Discounts: 21% off an item priced $63 saves $13.23, so you pay $49.77.

Adding and taking away 21%

Increasing 63 by 21% gives 76.23 and decreasing it by 21% gives 49.77. These do not cancel out: raising 63 by 21% and then lowering the result by 21% ends at 60.2217, because the second 21% is taken of a bigger number.
