Horse Racing Odds
A six-runner race where implied probabilities sum to 112% has a 12% overround—meaning the bookmaker’s theoretical margin is 12% before any punter places a bet.

Checking the overround before you bet is not something most punters do, but it takes less than a minute with a calculator or an odds comparison site.
The punter who understands odds mechanics and monitors these differences consistently captures value; the one who does not subsidises bookmaker profits. On short-priced selections — odds-on or evens — the exchange commission can actually make the bookmaker price competitive or even better, because the commission is a fixed percentage of the profit regardless of the odds. The difference between 3/1 and 7/2 is not dramatic on a single bet, but across 200 bets over a season it represents dozens of units of profit or loss.
