How to work it out

  1. Difference: 88 − 11 = 77
  2. Divide by the starting value: 77 ÷ 11 = 7
  3. Multiply by 100: 700%
  4. Check: Work forwards from the start: 11 × (1 + 7) = 11 × 8 = 88.

In a spreadsheet: =(88-11)/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 times the old one: for every 100 at the start there are now 800. The value has more than doubled.

Prices: an item whose price rises from $11 to $88 has gone up by 700%.

Why the change back is different

A 700% rise followed by a 700% fall does not bring you back to 11: it gives -528. The second percentage is taken of 88, not of 11, so to undo this change you need 87.5% instead.
