How to work it out

  1. Difference: 20 − 14 = 6
  2. Divide by the starting value: 6 ÷ 14 = 0.428571
  3. Multiply by 100: 42.8571%
  4. Check: Work forwards from the start: 14 × (1 + 0.428571) = 14 × 1.428571 = 20.

In a spreadsheet: =(20-14)/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 1.4286 times the old one: for every 100 at the start there are now 142.8571.

Prices: an item whose price rises from $14 to $20 has gone up by 42.8571%.

Why the change back is different

A 42.8571% rise followed by a 42.8571% fall does not bring you back to 14: it gives 11.4286. The second percentage is taken of 20, not of 14, so to undo this change you need 30% instead.
