How to work it out

  1. Turn the percentage into a decimal: 300 ÷ 100 = 3
  2. Multiply: 3 × 20 = 60
  3. Check: Work backwards: 60 ÷ 20 × 100 = 300%.

Another method. As a proportion of part to whole: 300/100 = part/20, so part = 300 × 20 ÷ 100 = 60. Both methods always give the same answer.

In a spreadsheet: =300%*20. 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 300% is more than 100%, the answer is bigger than 20: it is 3 times 20.

Mark-ups: pricing an item at 300% of its $20 cost means selling it for $60.

Adding and taking away 300%

Increasing 20 by 300% gives 80. These do not cancel out: raising 20 by 300% and then lowering the result by 300% ends at -160, because the second 300% is taken of a bigger number.
