Still needed: loss %
The change between two prices is (new / start - 1) x 100.
After a loss of L percent you hold 1 - L/100 of your starting value. To get back to 1 you need to multiply by 1 / (1 - L/100), so the gain needed is (1 / (1 - L/100) - 1) x 100.
That is why a 50% loss needs a 100% gain, and a 90% loss needs a 900% gain. A 100% loss cannot be recovered at all.
