How to work it out

  1. Difference: 90 − 68 = 22
  2. Divide by the starting value: 22 ÷ 68 = 0.323529
  3. Multiply by 100: 32.3529%
  4. Check: Work forwards from the start: 68 × (1 + 0.323529) = 68 × 1.323529 = 90.

In a spreadsheet: =(90-68)/68*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 1.3235 times the old one: for every 100 at the start there are now 132.3529.

Prices: an item whose price rises from $68 to $90 has gone up by 32.3529%.

Why the change back is different

A 32.3529% rise followed by a 32.3529% fall does not bring you back to 68: it gives 60.8824. The second percentage is taken of 90, not of 68, so to undo this change you need 24.4444% instead.
