How to work it out

  1. Difference: 34 − 14 = 20
  2. Divide by the starting value: 20 ÷ 14 = 1.428571
  3. Multiply by 100: 142.8571%
  4. Check: Work forwards from the start: 14 × (1 + 1.428571) = 14 × 2.428571 = 34.

In a spreadsheet: =(34-14)/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 2.4286 times the old one: for every 100 at the start there are now 242.8571. The value has more than doubled.

Prices: an item whose price rises from $14 to $34 has gone up by 142.8571%.

Why the change back is different

A 142.8571% rise followed by a 142.8571% fall does not bring you back to 14: it gives -14.5714. The second percentage is taken of 34, not of 14, so to undo this change you need 58.8235% instead.
