How to work it out

  1. Difference: 78 − 55 = 23
  2. Divide by the starting value: 23 ÷ 55 = 0.418182
  3. Multiply by 100: 41.8182%
  4. Check: Work forwards from the start: 55 × (1 + 0.418182) = 55 × 1.418182 = 78.

In a spreadsheet: =(78-55)/55*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 1.4182 times the old one: for every 100 at the start there are now 141.8182.

Prices: an item whose price rises from $55 to $78 has gone up by 41.8182%.

Why the change back is different

A 41.8182% rise followed by a 41.8182% fall does not bring you back to 55: it gives 45.3818. The second percentage is taken of 78, not of 55, so to undo this change you need 29.4872% instead.
