Dead Heat Calculator and Betting Rules: Returns After a Tie
A selection can be officially a winner while returning much less than the betting slip's pre-tie projection. The original odds stay fixed; the stake portion used in settlement changes.
Calculate a tie across one or several remaining places
Enter the original stake, accepted odds, remaining paid places and number of tied selections. The place ratio is capped at one.
- Stake settled at odds
- 10.00 units
- Stake portion lost
- 20.00 units
- Gross return
- 50.00 units
- Net result
- 20.00 units
Settled stake = original stake × remaining paid places ÷ tied selections, capped at the original stake. Verify whether the named market uses dead-heat rules before applying the result.

The dead-heat return formula
Betfair's published rule describes the two‑way treatment:
“half the stake is applied to the selection at full odds and the other half is lost”
For P remaining paid places shared by N tied selections:
settled stake = original stake x min(1, P / N)
total return = settled stake x decimal odds
net profit or loss = total return - original stake
The subtraction uses the original stake because the unallocated portion is lost. Do not subtract only the reduced stake.
Dead-heat settlement
A two-way tie applies half the stake at full odds
At decimal 5.00, the 10-unit settled portion returns 50 units. Against the original 20-unit stake, net profit is 30 units.
For stake S, decimal odds D, remaining places P and tied selections N,
the compact formula is:
total return = S x min(1, P / N) x D
This formula produces the same return as reducing the stake first. Showing the reduced stake is usually clearer because it matches published rule language.
Two-way and three-way dead-heat examples
Example 1: two‑way tie
- stake: 20 units;
- accepted decimal odds: 4.00;
- tied winners: 2;
- settled stake:
20 / 2 = 10 units; - total return:
10 x 4.00 = 40 units; - net profit:
40 - 20 = 20 units.
Without the dead heat, the projected total return would have been 80 units. The dead-heat return is 40 units.
Example 2: three‑way tie
- stake: 30 units;
- accepted decimal odds: 9.00;
- tied winners: 3;
- settled stake:
30 / 3 = 10 units; - total return:
10 x 9.00 = 90 units; - net profit:
90 - 30 = 60 units.
| Settlement | Original stake | Decimal odds | Tied winners | Total return | Net result |
|---|---|---|---|---|---|
| No tie | 30 units | 9.00 | 1 | 270 units | +240 units |
| Two-way dead heat | 30 units | 9.00 | 2 | 135 units | +105 units |
| Three-way dead heat | 30 units | 9.00 | 3 | 90 units | +60 units |

Example 3: fractional odds
A 24-unit stake at 5/1 has decimal odds of 6.00. In a two‑way tie:
24 / 2 x 6.00 = 72 units total return
The net profit is 72 - 24 = 48 units. Convert the fraction to decimal first
and use one consistent return formula.
How a winning selection can still lose money
If the decimal odds are lower than the number of tied winners, the total return is smaller than the original stake.
Example:
- stake: 100 units;
- odds: 1.50;
- two‑way tie;
- return:
100 x 1.50 / 2 = 75 units; - net result:
75 - 100 = -25 units.
The bet is classified as a dead-heat winner, but the settlement produces a 25-unit net loss. This is not an extra fee. Half the stake wins at 1.50 and the other half loses.
When one paid place remains, the break‑even condition is:
decimal odds = number of tied winners
At 2.00 in a two-way dead heat, total return equals the original stake. At 3.00 in a three-way dead heat, it also equals the original stake. With more than one remaining place, use the full place‑ratio formula instead.
When dead-heat rules do not apply
Specific sport and market rules can replace the general dead-heat method. Check them before calculating.
Common alternatives include:
- a playoff or countback determines one official winner;
- the market offers "tie" as a separate outcome;
- a head-to-head market declares a push or void;
- an outright market specifies joint‑winner settlement;
- official corrections change the final placing;
- a market pays a fixed number of places under separate place terms.

| Two golfers tied after all required holes | Dead heat may apply | Playoff and outright-winner rules. |
| Three-way match market includes Draw | Draw selection settles | A tie is already a priced outcome. |
| Top scorer tied on goals | Dead heat may apply | Tie-breakers such as assists or minutes. |
| Race result changed on enquiry | Official result rule applies | Settlement point and later-correction policy. |

The phrase "tie" in a result does not by itself prove that a dead-heat reduction applies. The market must have multiple selections sharing a winning position under the relevant rules.
Dead heats in each-way and place betting
An each-way bet contains a win part and a place part. A dead heat can affect one part without affecting the other.
Suppose a golfer is tied with another player for the last paid place:
- the win part has already lost if the golfer did not win;
- the place part can be subject to a dead‑heat division;
- the place odds first follow the advertised each‑way fraction;
- the dead-heat rule then applies to the relevant place stake under the operator's terms.
Do not divide the entire combined stake if only one component is tied. Split the receipt into its win and place lines, then calculate the affected line.
Pool bets can use an entirely different mechanism because winning units share a net pool. The Tote betting guide explains why a pool dividend is not a fixed‑odds dead‑heat return.
Dead-heat settlement checklist
- Confirm the official finishing position.
- Count the selections tied for the relevant winning place.
- Read the sport, market and promotion‑specific rules.
- Check for a playoff, countback or separate tie outcome.
- Split win and place components when needed.
- Divide only the affected stake by tied winners.
- Apply the original accepted odds to that reduced stake.
- Subtract the full original affected stake to find net profit or loss.
- Save the rule and official result if you dispute settlement.
Rebuild the return from stake, odds and tie count
Separate total return from profit and compare each receipt line with the applicable market rule.

FAQ
What is a dead heat in betting?
It is a tie between two or more selections for a winning place when no market-specific rule produces one outright winner.
How do I calculate a two-way dead heat?
If one paid place remains, divide the stake by two, settle that half at the original odds and treat the other half as lost. If two places remain, the full stake can be settled.
How do I calculate a three-way dead heat?
With one place left, divide the stake by three and settle one third at the accepted odds. With two places left, settle two thirds. The calculator handles both cases.
Can a dead-heat winner lose money?
Yes. If the decimal odds are lower than the number of tied winners, the reduced total return is below the original stake.
Do dead-heat rules always apply to ties?
No. A playoff, separate tie outcome, countback or sport-specific rule can determine a different settlement.
