What is a single bet?
A single is the simplest bet — one selection, one outcome. You pick a result (a team to win, a horse to place, a score), stake your money, and if you're right, you get paid at the advertised odds. If you're wrong, you lose your stake.
Understanding the odds
Odds tell you two things: how much you'll win and the implied probability of the outcome. 2/1 means you win £2 for every £1 staked, and implies a 33% chance. The bookmaker's margin means the implied probability is always slightly higher than the true probability.
Singles vs accumulators
Singles are lower risk, lower reward. An accumulator multiplies the odds together for bigger potential returns, but one loser kills the whole bet. Most experienced bettors prefer singles because the value is clearer and the bookmaker's margin doesn't compound.
How the single bet calculator works
How returns are calculated
A single bet pays returns equal to your stake multiplied by the decimal odds. At 5/1 (6.00 decimal), a £1 stake returns £6.00 — your £1 stake plus £5.00 profit. The calculation is straightforward: returns = stake × decimal odds.
Understanding implied probability
Every set of odds implies a probability. At 5/1, the implied probability is 1 ÷ 6.00 = 16.7%. This means the bookmaker's odds suggest a roughly 1-in-6 chance of winning. The visual bar above shows this at a glance — the shorter the bar, the less likely (and more rewarding) the outcome.
Each way singles
An each way single is two bets: one to win and one to place. The place bet pays at a fraction of the win odds — typically 1/4 or 1/5 of the odds. If your selection wins, both bets pay out. If it places but doesn't win, only the place portion pays. This doubles your total stake but provides a safety net.
