How to work it out

  1. Difference: 82 − 55 = 27
  2. Divide by the starting value: 27 ÷ 55 = 0.490909
  3. Multiply by 100: 49.0909%
  4. Check: Work forwards from the start: 55 × (1 + 0.490909) = 55 × 1.490909 = 82.

In a spreadsheet: =(82-55)/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 1.4909 times the old one: for every 100 at the start there are now 149.0909.

Prices: an item whose price rises from $55 to $82 has gone up by 49.0909%.

Why the change back is different

A 49.0909% rise followed by a 49.0909% fall does not bring you back to 55: it gives 41.7455. The second percentage is taken of 82, not of 55, so to undo this change you need 32.9268% instead.
