How to work it out

  1. Turn the percentage into a decimal: 125 ÷ 100 = 1.25
  2. Multiply: 1.25 × 80 = 100
  3. Check: Work backwards: 100 ÷ 80 × 100 = 125%.

Another method. As a proportion of part to whole: 125/100 = part/80, so part = 125 × 80 ÷ 100 = 100. Both methods always give the same answer.

In a spreadsheet: =125%*80. 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 125% is more than 100%, the answer is bigger than 80: it is 1.25 times 80.

Mark-ups: pricing an item at 125% of its $80 cost means selling it for $100.

Adding and taking away 125%

Increasing 80 by 125% gives 180. These do not cancel out: raising 80 by 125% and then lowering the result by 125% ends at -45, because the second 125% is taken of a bigger number.
