The Mathematics
For one position shared by h horses, the successful stake portion is original stake ÷ h. Multiply that reduced stake by decimal odds to obtain return, then subtract the full original stake to calculate profit. For a place leg, first convert the win odds to the advertised place price. The general available-places formula is ordinary return × available paid places ÷ tied runners, but this widget assumes available paid places equals one.
Simple win return = stake × decimal odds ÷ tied runners
Place decimal = 1 + (win decimal − 1) × place fraction
Simple place-leg return = place stake × place decimal ÷ tied runners
Profit for entered leg = reduced return − original entered stake
General tied-group factor = available paid places ÷ tied runners (not implemented here)
Worked Example
Enter £10, 4/1, Win and 2 runners. Normal return is £50. The successful stake is £10 ÷ 2 = £5, giving £5 × 5 = £25 return and £15 profit after the original £10 outlay. At the same price with 3 tied winners, return is £50 ÷ 3 = £16.67 rounded, and profit is £6.67.
How do I enter a win or place dead heat?
Enter the cash stake on the affected leg, the original fractional win odds, and the number of horses sharing the position: two, three or four. Choose Win for a tie for first. Choose Place to calculate an affected place leg and select its each way fraction. Even in Place mode, enter the original win price; the tool derives the place price from that quote and fraction.
The stake in Place mode is only the place-leg stake, not the total each way outlay. At £10 each way, the full ticket costs £20 but the affected place leg has a £10 stake. The displayed place-mode profit subtracts that £10 only. To assess the whole each way ticket, add any payable win-leg return and subtract the full £20. A non-winning placed horse has no win-leg payout.
Why is halving winnings alone incorrect?
The dead-heat reduction applies to the return from the successful stake portion, not merely to the profit followed by a full stake refund. At £10 and 4/1, halving £40 profit and adding the whole £10 would give £30. The correct two-horse win return is £25: £5 at decimal 5.00, with the other £5 stake portion lost. The distinction matters especially at shorter prices.
At evens, a £10 bet normally returns £20. A two-horse win dead heat reduces that to £10, so it breaks even overall rather than making £5 profit. At 1/2, the normal £15 return becomes £7.50, leaving a £2.50 loss despite a winning tie. A declared winner is therefore not guaranteed to produce positive cash profit when dead-heat rules apply.
When is dividing by tied-runner count insufficient?
Consider three horses tied for third in a four-place market, with first and second already occupied. Two paid places remain for the three tied horses, so the general successful fraction is 2/3, not 1/3. If the ordinary place return is £30, settlement is £20 rather than £10. This widget has no available-places input, so it cannot produce that general case correctly; calculate the fraction separately using the actual market rules.
Conversely, two horses tying for third in a three-place market share one remaining place, so each receives half the ordinary place return. That is the simple one-position scenario supported here. If a tie does not cross the boundary of paid places, a place leg may not need a reduction at all. The finishing position and number of places advertised matter, not simply the fact that a photo finish resulted in a tie.
How do each way and multiple settlements differ?
For £10 each way at 8/1 and quarter odds, the normal place leg returns £30. A two-horse tie for the last single paid place gives £15 from that leg. If neither is a winner, the full ticket result is £15 − £20 = a £5 loss. The tool's place-leg result is £15 − £10 = £5 profit, which is not the whole-ticket profit. Keep the accounting boundary explicit.
A win dead heat can affect the win portion while the place portion settles differently. Multiples require the appropriate reduction for each affected component, while Rule 4 and exchange commission introduce separate adjustments. This tool does not combine those situations, look up official finishing positions or retrieve an operator's enhanced dead-heat concession. Treat it as a simple affected-leg calculation and use the source rules to check more complex settlements.
Popular questions about this calculator
What does a £10 bet at 4/1 return in a two-horse dead heat?
For a simple win dead heat, £25 including the successful stake portion. Profit is £15 after subtracting the original £10. The calculation is £10 × decimal 5.00 ÷ 2, not half the £40 profit plus a full £10 stake refund.
Is the whole stake returned after a dead heat?
Not under ordinary proportional dead-heat settlement. Only the successful stake portion earns a payout at full odds; the rest is lost. In a two-horse win tie, half the stake succeeds. This differs from Rule 4, which normally preserves the outright winner's returned cash stake.
Can a winning dead heat produce a loss?
Yes. A £10 cash bet at 1/2 has a £15 ordinary return. A two-horse win tie returns £7.50, leaving a £2.50 loss. The horse sharing first place does not mean the full original stake has been recovered.
What stake should I enter for an each way place dead heat?
Enter the place-leg stake only. For £10 each way, enter £10, not the £20 combined outlay. The displayed profit then belongs to that leg. For the full ticket, add any win return and subtract the combined £20 cost separately.
Do I enter win odds or place odds in Place mode?
Enter the original win odds and select the place fraction. At 8/1 and quarter odds the tool derives place odds of 2/1, or decimal 3.00. Entering 2/1 as the original win price would incorrectly apply the fraction a second time.
Does this calculator support tied horses sharing several places?
No. It divides by tied-runner count and assumes one paid position for the tied group. If three horses share two remaining paid places, the correct general factor is 2/3, not 1/3. There is no available-places control in this widget.
What happens if two horses tie for the last paid place?
If one paid place remains, each tied selection receives half its ordinary place return under standard treatment. At a normal £30 place return, that means £15. Check the advertised positions and official result; a tie entirely inside the paid places can settle differently.
Does every each way leg get halved in a win dead heat?
Not necessarily. Win and place portions are assessed against their own winning conditions and paid positions. The win leg may be divided while the place leg remains fully eligible. This calculator handles one affected leg and does not automatically combine a full each way settlement.
Can I include Rule 4 in the dead-heat calculator?
There is no Rule 4 input. A ticket affected by both requires the deduction and successful stake proportion to be applied under the operator's rules. The separate Rule 4 tool shows a simple outright-win adjustment, not an integrated dead-heat settlement.
Does this tool calculate exchange commission or bookmaker concessions?
No. It displays gross simple-leg returns at the supplied prices and terms. Account-specific exchange fees and enhanced dead-heat offers are not included. Consult the accepted market rules and settled slip before treating its gross figure as the final amount received.
