How to work it out

  1. Difference: 20 − 19 = 1
  2. Divide by the starting value: 1 ÷ 19 = 0.052632
  3. Multiply by 100: 5.2632%
  4. Check: Work forwards from the start: 19 × (1 + 0.052632) = 19 × 1.052632 = 20.

In a spreadsheet: =(20-19)/19*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 1.0526 times the old one: for every 100 at the start there are now 105.2632.

Prices: an item whose price rises from $19 to $20 has gone up by 5.2632%.

Why the change back is different

A 5.2632% rise followed by a 5.2632% fall does not bring you back to 19: it gives 18.9474. The second percentage is taken of 20, not of 19, so to undo this change you need 5% instead.
