How to work it out

  1. Difference: 100 − 68 = 32
  2. Divide by the starting value: 32 ÷ 68 = 0.470588
  3. Multiply by 100: 47.0588%
  4. Check: Work forwards from the start: 68 × (1 + 0.470588) = 68 × 1.470588 = 100.

In a spreadsheet: =(100-68)/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 1.4706 times the old one: for every 100 at the start there are now 147.0588.

Prices: an item whose price rises from $68 to $100 has gone up by 47.0588%.

Why the change back is different

A 47.0588% rise followed by a 47.0588% fall does not bring you back to 68: it gives 52.9412. The second percentage is taken of 100, not of 68, so to undo this change you need 32% instead.
