How to work it out

  1. Difference: 68 − 38 = 30
  2. Divide by the starting value: 30 ÷ 38 = 0.789474
  3. Multiply by 100: 78.9474%
  4. Check: Work forwards from the start: 38 × (1 + 0.789474) = 38 × 1.789474 = 68.

In a spreadsheet: =(68-38)/38*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 1.7895 times the old one: for every 100 at the start there are now 178.9474.

Prices: an item whose price rises from $38 to $68 has gone up by 78.9474%.

Why the change back is different

A 78.9474% rise followed by a 78.9474% fall does not bring you back to 38: it gives 14.3158. The second percentage is taken of 68, not of 38, so to undo this change you need 44.1176% instead.
