How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 63 = 54.81
  3. Check: Work backwards: 54.81 ÷ 63 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/63, so part = 87 × 63 ÷ 100 = 54.81. Both methods always give the same answer.

In a spreadsheet: =87%*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

54.81 is the 87% share of 63. The remaining 13% is 8.19, and the two parts add back up to 63.

Discounts: 87% off an item priced $63 saves $54.81, so you pay $8.19.

Adding and taking away 87%

Increasing 63 by 87% gives 117.81 and decreasing it by 87% gives 8.19. These do not cancel out: raising 63 by 87% and then lowering the result by 87% ends at 15.3153, because the second 87% is taken of a bigger number.
