How to work it out

  1. Difference: 78 − 7 = 71
  2. Divide by the starting value: 71 ÷ 7 = 10.142857
  3. Multiply by 100: 1,014.2857%
  4. Check: Work forwards from the start: 7 × (1 + 10.142857) = 7 × 11.142857 = 78.

In a spreadsheet: =(78-7)/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 11.1429 times the old one: for every 100 at the start there are now 1,114.2857. The value has more than doubled.

Prices: an item whose price rises from $7 to $78 has gone up by 1,014.2857%.

Why the change back is different

A 1,014.2857% rise followed by a 1,014.2857% fall does not bring you back to 7: it gives -713.1429. The second percentage is taken of 78, not of 7, so to undo this change you need 91.0256% instead.
