How to work it out

  1. Difference: 54 − 29 = 25
  2. Divide by the starting value: 25 ÷ 29 = 0.862069
  3. Multiply by 100: 86.2069%
  4. Check: Work forwards from the start: 29 × (1 + 0.862069) = 29 × 1.862069 = 54.

In a spreadsheet: =(54-29)/29*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 1.8621 times the old one: for every 100 at the start there are now 186.2069.

Prices: an item whose price rises from $29 to $54 has gone up by 86.2069%.

Why the change back is different

A 86.2069% rise followed by a 86.2069% fall does not bring you back to 29: it gives 7.4483. The second percentage is taken of 54, not of 29, so to undo this change you need 46.2963% instead.
