How to work it out

  1. Difference: 53 − 42 = 11
  2. Divide by the starting value: 11 ÷ 42 = 0.261905
  3. Multiply by 100: 26.1905%
  4. Check: Work forwards from the start: 42 × (1 + 0.261905) = 42 × 1.261905 = 53.

In a spreadsheet: =(53-42)/42*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 1.2619 times the old one: for every 100 at the start there are now 126.1905.

Prices: an item whose price rises from $42 to $53 has gone up by 26.1905%.

Why the change back is different

A 26.1905% rise followed by a 26.1905% fall does not bring you back to 42: it gives 39.119. The second percentage is taken of 53, not of 42, so to undo this change you need 20.7547% instead.
