Hello !
The Bookmaker (or Exchanger) Betfair take 6.5% commission on winnings.
e.g:If the odds is 3.5 and you bet 100$, you earn : (100x3.5)-100=250 - 6.5%=233.75
I need a formula in excel so that when I input the odds, it gives me the real odds (the odds less the 6.5% commission on winnings).
Is it possible ?
