How to work it out

  1. Difference: 83 − 12 = 71
  2. Divide by the starting value: 71 ÷ 12 = 5.916667
  3. Multiply by 100: 591.6667%
  4. Check: Work forwards from the start: 12 × (1 + 5.916667) = 12 × 6.916667 = 83.

In a spreadsheet: =(83-12)/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 6.9167 times the old one: for every 100 at the start there are now 691.6667. The value has more than doubled.

Prices: an item whose price rises from $12 to $83 has gone up by 591.6667%.

Why the change back is different

A 591.6667% rise followed by a 591.6667% fall does not bring you back to 12: it gives -408.0833. The second percentage is taken of 83, not of 12, so to undo this change you need 85.5422% instead.
