How to work it out

  1. Difference: 67 − 21 = 46
  2. Divide by the starting value: 46 ÷ 21 = 2.190476
  3. Multiply by 100: 219.0476%
  4. Check: Work forwards from the start: 21 × (1 + 2.190476) = 21 × 3.190476 = 67.

In a spreadsheet: =(67-21)/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 3.1905 times the old one: for every 100 at the start there are now 319.0476. The value has more than doubled.

Prices: an item whose price rises from $21 to $67 has gone up by 219.0476%.

Why the change back is different

A 219.0476% rise followed by a 219.0476% fall does not bring you back to 21: it gives -79.7619. The second percentage is taken of 67, not of 21, so to undo this change you need 68.6567% instead.
