How to work it out

  1. Difference: 56 − 49 = 7
  2. Divide by the starting value: 7 ÷ 49 = 0.142857
  3. Multiply by 100: 14.2857%
  4. Check: Work forwards from the start: 49 × (1 + 0.142857) = 49 × 1.142857 = 56.

In a spreadsheet: =(56-49)/49*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 1.1429 times the old one: for every 100 at the start there are now 114.2857.

Prices: an item whose price rises from $49 to $56 has gone up by 14.2857%.

Why the change back is different

A 14.2857% rise followed by a 14.2857% fall does not bring you back to 49: it gives 48. The second percentage is taken of 56, not of 49, so to undo this change you need 12.5% instead.
