Treble calculator guide: returns, each-way bets and Rule 4
Check treble returns with precise worked examples, including void selections, each-way place prices, Rule 4 deductions and the difference between return and profit.
Published: Last updated:
A treble is one bet containing three selections. For an ordinary win-only treble, all three must win unless a selection is void and removed under the applicable rules. A treble calculator multiplies the relevant decimal prices and stake; it cannot predict whether those selections will win.
Use the BCP bet calculator for the calculation, then check the inputs and settlement assumptions below. The worked prices are hypothetical, not current odds for named matches or runners.
Treble return versus profit
Decimal odds include the returned cash stake. Convert fractional odds by dividing the numerator by the denominator and adding one. For example, 2/1 is 3.00, 5/4 is 2.25 and 6/4 is 2.50. Multiply the three decimal prices rather than adding them.
| Step | £10 cash-stake example | Return carried forward |
|---|---|---|
| First selection wins | £10 × 3.00 | £30 |
| Second selection wins | £30 × 2.25 | £67.50 |
| Third selection wins | £67.50 × 2.50 | £168.75 |
The combined decimal price is 16.875. A winning £10 treble therefore returns £168.75, including the original stake, for £158.75 profit. If any selection loses, the ordinary treble returns £0: the other winning selections are not paid as separate singles.
Keep the full price until the last step
Rounding each decimal conversion before multiplying can change a payout example. At fractional odds of 4/6, 6/4 and 11/10, the exact decimals are 5/3, 2.50 and 2.10. Their product is 8.75, so a winning £10 treble returns £87.50 and £77.50 profit. Using 1.67 instead of 5/3 prematurely gives a different result.
These calculations assume cash stakes and no deductions, dead heats or promotional additions. The accepted slip and operator’s settlement rules determine the actual payout; a rounded displayed price should not replace a more precise price in a worked calculation.
Void selections and non-runners
bet365’s UK non-runner guidance says an ordinary treble with one void non-runner becomes a double on the remaining selections. In the first example, if the third selection is void and the other two win, £10 × 3.00 × 2.25 returns £67.50. A losing selection is not void. Ante-post bets can instead be all-in, run or not; check their specific conditions.
Rule 4 changes winnings, not the returned stake
For a simple win-only racing calculation, a 25p-in-the-pound Rule 4 deduction removes 25% of the winnings component on the affected leg. At 4/1, the profit multiplier is 4.00: 4.00 × 0.75 = 3.00, then add the stake component to obtain 4.00 decimal. Multiplying the whole 5.00 decimal price by 0.75 would incorrectly deduct from the returned stake too.
With hypothetical other legs at 2.00 and 3.00, a £10 treble using that adjusted 4.00 price returns £240 if all win. This is one simplified deduction example, not a universal racing settlement. Use the actual deduction, price timing, market and terms, including any further withdrawals.
Each-way and dead-heat calculations
An each-way treble has a win treble and a separately staked place treble. £5 each way costs £10 in total. Use each leg’s advertised place fraction and qualifying places for the place side; do not multiply the full win decimals for both parts.
For three hypothetical 4/1 selections with one-fifth place odds, each place decimal is 1.80. If all three qualify for places but do not all win, the £5 place treble returns £5 × 1.80³ = £29.16; the win treble loses. Against the whole £10 stake, that is £19.16 profit. These place terms are illustrative, not a claim about a current race.
A dead heat is another distinct adjustment. In a simple two-way tie for one winning position, the affected stake is split between the tied winners; it is not treated as a full win. Apply the exact market’s dead-heat rules before carrying the adjusted return into other legs.
Before using the result
Confirm the three accepted selections, odds, cash or promotional stake, outcomes and any adjustments. Related selections cannot automatically be combined at multiplied ordinary prices. A Trixie is different: it has four lines, not one treble, and a different total cost.
