How to work it out

  1. Difference: 98 − 21 = 77
  2. Divide by the starting value: 77 ÷ 21 = 3.666667
  3. Multiply by 100: 366.6667%
  4. Check: Work forwards from the start: 21 × (1 + 3.666667) = 21 × 4.666667 = 98.

In a spreadsheet: =(98-21)/21*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 4.6667 times the old one: for every 100 at the start there are now 466.6667. The value has more than doubled.

Prices: an item whose price rises from $21 to $98 has gone up by 366.6667%.

Why the change back is different

A 366.6667% rise followed by a 366.6667% fall does not bring you back to 21: it gives -261.3333. The second percentage is taken of 98, not of 21, so to undo this change you need 78.5714% instead.
