How to work it out

  1. Difference: 46 − 21 = 25
  2. Divide by the starting value: 25 ÷ 21 = 1.190476
  3. Multiply by 100: 119.0476%
  4. Check: Work forwards from the start: 21 × (1 + 1.190476) = 21 × 2.190476 = 46.

In a spreadsheet: =(46-21)/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 2.1905 times the old one: for every 100 at the start there are now 219.0476. The value has more than doubled.

Prices: an item whose price rises from $21 to $46 has gone up by 119.0476%.

Why the change back is different

A 119.0476% rise followed by a 119.0476% fall does not bring you back to 21: it gives -8.7619. The second percentage is taken of 46, not of 21, so to undo this change you need 54.3478% instead.
