How it works
Each selection gets a share of the bankroll in proportion to its implied probability, so every winning outcome returns the same amount. Stake equals total stake times one over the odds, divided by the sum of one over every price.
If those implied probabilities add up to less than 100% you are looking at an arb: the market is paying more than certainty is worth, and the profit is locked whichever selection wins. Add a commission rate if you are dutching on an exchange — it is taken off the guaranteed return, not off each stake.
Most bookmakers won't take the exact stake this math produces — some round to the nearest 0.50, others to whole numbers only. Stake rounding adjusts every stake to the increment you pick, handing the leftover to whichever selections were closest to rounding up first, so the total still matches what you asked for. It also means the return is no longer perfectly equal across selections — that's the real, placeable trade-off, not a bug.
Worked example
Three runners at +150, +300 and +500 on a $100 bankroll. Implied probabilities are 40%, 25% and 16.7% — a book of 81.7%, so the market leaves room.
| +150 | $48.98 |
| +300 | $30.61 |
| +500 | $20.41 |
| Return, any winner | $122.45 |
