How to work it out

  1. Difference: 89 − 11 = 78
  2. Divide by the starting value: 78 ÷ 11 = 7.090909
  3. Multiply by 100: 709.0909%
  4. Check: Work forwards from the start: 11 × (1 + 7.090909) = 11 × 8.090909 = 89.

In a spreadsheet: =(89-11)/11*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 8.0909 times the old one: for every 100 at the start there are now 809.0909. The value has more than doubled.

Prices: an item whose price rises from $11 to $89 has gone up by 709.0909%.

Why the change back is different

A 709.0909% rise followed by a 709.0909% fall does not bring you back to 11: it gives -542.0909. The second percentage is taken of 89, not of 11, so to undo this change you need 87.6404% instead.
