How to work it out

  1. Difference: 17 − 12 = 5
  2. Divide by the starting value: 5 ÷ 12 = 0.416667
  3. Multiply by 100: 41.6667%
  4. Check: Work forwards from the start: 12 × (1 + 0.416667) = 12 × 1.416667 = 17.

In a spreadsheet: =(17-12)/12*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 1.4167 times the old one: for every 100 at the start there are now 141.6667.

Prices: an item whose price rises from $12 to $17 has gone up by 41.6667%.

Why the change back is different

A 41.6667% rise followed by a 41.6667% fall does not bring you back to 12: it gives 9.9167. The second percentage is taken of 17, not of 12, so to undo this change you need 29.4118% instead.
