How to work it out

  1. Difference: 96 − 66 = 30
  2. Divide by the starting value: 30 ÷ 66 = 0.454545
  3. Multiply by 100: 45.4545%
  4. Check: Work forwards from the start: 66 × (1 + 0.454545) = 66 × 1.454545 = 96.

In a spreadsheet: =(96-66)/66*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 1.4545 times the old one: for every 100 at the start there are now 145.4545.

Prices: an item whose price rises from $66 to $96 has gone up by 45.4545%.

Why the change back is different

A 45.4545% rise followed by a 45.4545% fall does not bring you back to 66: it gives 52.3636. The second percentage is taken of 96, not of 66, so to undo this change you need 31.25% instead.
