How to work it out

  1. Difference: 77 − 14 = 63
  2. Divide by the starting value: 63 ÷ 14 = 4.5
  3. Multiply by 100: 450%
  4. Check: Work forwards from the start: 14 × (1 + 4.5) = 14 × 5.5 = 77.

In a spreadsheet: =(77-14)/14*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 5.5 times the old one: for every 100 at the start there are now 550. The value has more than doubled.

Prices: an item whose price rises from $14 to $77 has gone up by 450%.

Why the change back is different

A 450% rise followed by a 450% fall does not bring you back to 14: it gives -269.5. The second percentage is taken of 77, not of 14, so to undo this change you need 81.8182% instead.
