How to work it out

  1. Difference: 56 − 54 = 2
  2. Divide by the starting value: 2 ÷ 54 = 0.037037
  3. Multiply by 100: 3.7037%
  4. Check: Work forwards from the start: 54 × (1 + 0.037037) = 54 × 1.037037 = 56.

In a spreadsheet: =(56-54)/54*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 1.037 times the old one: for every 100 at the start there are now 103.7037.

Prices: an item whose price rises from $54 to $56 has gone up by 3.7037%.

Why the change back is different

A 3.7037% rise followed by a 3.7037% fall does not bring you back to 54: it gives 53.9259. The second percentage is taken of 56, not of 54, so to undo this change you need 3.5714% instead.
