How to work it out

  1. Difference: 66 − 2 = 64
  2. Divide by the starting value: 64 ÷ 2 = 32
  3. Multiply by 100: 3,200%
  4. Check: Work forwards from the start: 2 × (1 + 32) = 2 × 33 = 66.

In a spreadsheet: =(66-2)/2*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 33 times the old one: for every 100 at the start there are now 3,300. The value has more than doubled.

Prices: an item whose price rises from $2 to $66 has gone up by 3,200%.

Why the change back is different

A 3,200% rise followed by a 3,200% fall does not bring you back to 2: it gives -2,046. The second percentage is taken of 66, not of 2, so to undo this change you need 96.9697% instead.
