What is the formula to work out what the odds are after 5% commision? I know you can do the options on betfair, but I wanted to be able to work out what the actual odds were.
Odds of 1.5 Stake £10 = £5 profit -5% commison = 4.75, so odds were 1.47 (roughly) what is the calcualation to get the 1.5 down to 1.47ish?
