Takeout

The word comes from racing, where takeout is the slice the track removes from the betting pool before paying winners. Lotteries use the same idea under a different name. Operator documents usually quote the other side of it, the prize fund percentage or return to player, because a game returning 50% of stakes as prizes has a 50% takeout by definition.

Published figures put draw lotteries at the expensive end of gambling. The UK National Lottery allocates about 53% of stakes to the prize fund, with 25% to good causes, 12% to lottery duty, 4% to retailers and 5% to the operator. Powerball states that 35% of every $2 ticket stays in the jurisdiction where it was sold to fund public programmes, before commission and running costs are counted. Slot machines and sports betting return far more, often above 90 percent, because they rely on rapid repeated play rather than a single weekly purchase.

This is the whole reason the expected value of a ticket is negative and stays negative. At a 53% payout a £2 line is worth about £1.06 in expectation before anything else is considered. No selection method touches that. Picking birthdays, wheeling numbers or buying a quick pick all leave the payout percentage exactly where it was, because it is fixed by the game's rules rather than by the ticket. A large rollover is the one genuine exception, since it adds money staked in earlier draws to the current prize fund, though sharing among more winners usually eats the gain.
