How to work it out

  1. Difference: 89 − 42 = 47
  2. Divide by the starting value: 47 ÷ 42 = 1.119048
  3. Multiply by 100: 111.9048%
  4. Check: Work forwards from the start: 42 × (1 + 1.119048) = 42 × 2.119048 = 89.

In a spreadsheet: =(89-42)/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 2.119 times the old one: for every 100 at the start there are now 211.9048. The value has more than doubled.

Prices: an item whose price rises from $42 to $89 has gone up by 111.9048%.

Why the change back is different

A 111.9048% rise followed by a 111.9048% fall does not bring you back to 42: it gives -10.5952. The second percentage is taken of 89, not of 42, so to undo this change you need 52.809% instead.
