How to work it out

  1. Difference: 81 − 3 = 78
  2. Divide by the starting value: 78 ÷ 3 = 26
  3. Multiply by 100: 2,600%
  4. Check: Work forwards from the start: 3 × (1 + 26) = 3 × 27 = 81.

In a spreadsheet: =(81-3)/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 27 times the old one: for every 100 at the start there are now 2,700. The value has more than doubled.

Prices: an item whose price rises from $3 to $81 has gone up by 2,600%.

Why the change back is different

A 2,600% rise followed by a 2,600% fall does not bring you back to 3: it gives -2,025. The second percentage is taken of 81, not of 3, so to undo this change you need 96.2963% instead.
