How to work it out

  1. Difference: 61 − 20 = 41
  2. Divide by the starting value: 41 ÷ 20 = 2.05
  3. Multiply by 100: 205%
  4. Check: Work forwards from the start: 20 × (1 + 2.05) = 20 × 3.05 = 61.

In a spreadsheet: =(61-20)/20*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 3.05 times the old one: for every 100 at the start there are now 305. The value has more than doubled.

Prices: an item whose price rises from $20 to $61 has gone up by 205%.

Why the change back is different

A 205% rise followed by a 205% fall does not bring you back to 20: it gives -64.05. The second percentage is taken of 61, not of 20, so to undo this change you need 67.2131% instead.
