How to work it out

  1. Divide the part by the whole: 43 ÷ 42 = 1.02381
  2. Multiply by 100: 1.02381 × 100 = 102.381%
  3. Check: Work backwards: 102.381% of 42 is 1.02381 × 42 = 43.

Another method. As a proportion of part to whole: 43/42 = p/100, so p = 43 × 100 ÷ 42 = 102.381%. Both methods always give the same answer.

In a spreadsheet: =43/42*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.

What the result means

43 is more than the whole amount (1.024 times as much) of 42. 43 goes past 42 by 1, which is another 2.381% on top of the whole.

Targets: selling 43 items against a target of 42 means reaching 102.381% of the target, beating it by 2.381%.
