How to work it out

  1. Difference: 55 − 28 = 27
  2. Divide by the starting value: 27 ÷ 28 = 0.964286
  3. Multiply by 100: 96.4286%
  4. Check: Work forwards from the start: 28 × (1 + 0.964286) = 28 × 1.964286 = 55.

In a spreadsheet: =(55-28)/28*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 1.9643 times the old one: for every 100 at the start there are now 196.4286.

Prices: an item whose price rises from $28 to $55 has gone up by 96.4286%.

Why the change back is different

A 96.4286% rise followed by a 96.4286% fall does not bring you back to 28: it gives 1.9643. The second percentage is taken of 55, not of 28, so to undo this change you need 49.0909% instead.
