How to work it out

  1. Difference: 90 − 12 = 78
  2. Divide by the starting value: 78 ÷ 12 = 6.5
  3. Multiply by 100: 650%
  4. Check: Work forwards from the start: 12 × (1 + 6.5) = 12 × 7.5 = 90.

In a spreadsheet: =(90-12)/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 7.5 times the old one: for every 100 at the start there are now 750. The value has more than doubled.

Prices: an item whose price rises from $12 to $90 has gone up by 650%.

Why the change back is different

A 650% rise followed by a 650% fall does not bring you back to 12: it gives -495. The second percentage is taken of 90, not of 12, so to undo this change you need 86.6667% instead.
