How to work it out

  1. Difference: 100 − 7 = 93
  2. Divide by the starting value: 93 ÷ 7 = 13.285714
  3. Multiply by 100: 1,328.5714%
  4. Check: Work forwards from the start: 7 × (1 + 13.285714) = 7 × 14.285714 = 100.

In a spreadsheet: =(100-7)/7*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 14.2857 times the old one: for every 100 at the start there are now 1,428.5714. The value has more than doubled.

Prices: an item whose price rises from $7 to $100 has gone up by 1,328.5714%.

Why the change back is different

A 1,328.5714% rise followed by a 1,328.5714% fall does not bring you back to 7: it gives -1,228.5714. The second percentage is taken of 100, not of 7, so to undo this change you need 93% instead.
