How to work it out

  1. Difference: 66 − 3 = 63
  2. Divide by the starting value: 63 ÷ 3 = 21
  3. Multiply by 100: 2,100%
  4. Check: Work forwards from the start: 3 × (1 + 21) = 3 × 22 = 66.

In a spreadsheet: =(66-3)/3*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 22 times the old one: for every 100 at the start there are now 2,200. The value has more than doubled.

Prices: an item whose price rises from $3 to $66 has gone up by 2,100%.

Why the change back is different

A 2,100% rise followed by a 2,100% fall does not bring you back to 3: it gives -1,320. The second percentage is taken of 66, not of 3, so to undo this change you need 95.4545% instead.
