How to work it out

  1. Difference: 15 − 14 = 1
  2. Divide by the starting value: 1 ÷ 14 = 0.071429
  3. Multiply by 100: 7.1429%
  4. Check: Work forwards from the start: 14 × (1 + 0.071429) = 14 × 1.071429 = 15.

In a spreadsheet: =(15-14)/14*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 1.0714 times the old one: for every 100 at the start there are now 107.1429.

Prices: an item whose price rises from $14 to $15 has gone up by 7.1429%.

Why the change back is different

A 7.1429% rise followed by a 7.1429% fall does not bring you back to 14: it gives 13.9286. The second percentage is taken of 15, not of 14, so to undo this change you need 6.6667% instead.
