How to work it out

  1. Difference: 56 − 55 = 1
  2. Divide by the starting value: 1 ÷ 55 = 0.018182
  3. Multiply by 100: 1.8182%
  4. Check: Work forwards from the start: 55 × (1 + 0.018182) = 55 × 1.018182 = 56.

In a spreadsheet: =(56-55)/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 1.0182 times the old one: for every 100 at the start there are now 101.8182.

Prices: an item whose price rises from $55 to $56 has gone up by 1.8182%.

Why the change back is different

A 1.8182% rise followed by a 1.8182% fall does not bring you back to 55: it gives 54.9818. The second percentage is taken of 56, not of 55, so to undo this change you need 1.7857% instead.
