How to work it out

  1. Difference: 74 − 10 = 64
  2. Divide by the starting value: 64 ÷ 10 = 6.4
  3. Multiply by 100: 640%
  4. Check: Work forwards from the start: 10 × (1 + 6.4) = 10 × 7.4 = 74.

In a spreadsheet: =(74-10)/10*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 7.4 times the old one: for every 100 at the start there are now 740. The value has more than doubled.

Prices: an item whose price rises from $10 to $74 has gone up by 640%.

Why the change back is different

A 640% rise followed by a 640% fall does not bring you back to 10: it gives -399.6. The second percentage is taken of 74, not of 10, so to undo this change you need 86.4865% instead.
