How to work it out

  1. Difference: 100 − 13 = 87
  2. Divide by the starting value: 87 ÷ 13 = 6.692308
  3. Multiply by 100: 669.2308%
  4. Check: Work forwards from the start: 13 × (1 + 6.692308) = 13 × 7.692308 = 100.

In a spreadsheet: =(100-13)/13*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 7.6923 times the old one: for every 100 at the start there are now 769.2308. The value has more than doubled.

Prices: an item whose price rises from $13 to $100 has gone up by 669.2308%.

Why the change back is different

A 669.2308% rise followed by a 669.2308% fall does not bring you back to 13: it gives -569.2308. The second percentage is taken of 100, not of 13, so to undo this change you need 87% instead.
