calculate stake for fixed profit

[Krivo666]

Hi,

I'm trying to do some back testing on my betbook, and what I need to figure out is

I only know odds (say column A) and result I want to get which is say 10(in column C), how do I calculate stake so (odds*stake)-stake=10

Odds	Stake	Return	Profit
1.63	15.873	25.873	10
2.616	6.19	16.193	10

Stake = 10/(Odds-1)

brilliant, I couldn't get my head around it (never been good at maths)

thank you so much
