A Yankee is one of the most popular multiple bet types in horse racing and accumulator betting, combining 4 selections into 11 separate bets: 6 doubles, 4 trebles, and 1 fourfold accumulator. That structure means you can still profit even if one or two selections lose.

This calculator works out every one of those 11 bets automatically, handles each-way betting with proper place terms, and correctly deals with void or non-runner selections the way bookmakers actually settle them.
Whether you’re placing a Saturday racing Yankee or building a multi-sport accumulator system bet, seeing the full bet-by-bet breakdown makes it much easier to understand exactly where your returns are coming from.
📊 How to Use the Yankee Calculator
Enter the odds for all 4 selections in your Yankee, choosing Decimal or Fractional format. Enter your stake per bet — remember a Yankee is 11 total bets, so your stake per bet multiplied by 11 (or 22 for each-way) is your total outlay.
A £1 Yankee costs £11 total (6 doubles + 4 trebles + 1 fourfold), or £22 if backed each-way — always check your total stake before placing the bet.
Set each selection’s result using the Win/Placed/Void/Lose toggle. If you’re backing each-way, select your place fraction as well, and the calculator will work out both the win part and place part of every applicable bet.
🔢 Calculator Fields Explained
Odds Format – Whether you’re entering Decimal (e.g. 2.50) or Fractional (e.g. 6/4) odds.
Stake Per Bet – Your stake on each individual bet within the Yankee, not your total outlay.
Each-Way – Whether the Yankee is backed win-only or each-way, doubling the bet count to 22 when active.
Place Fraction – The fraction of the odds paid for a placed selection (e.g. 1/4, 1/5), only shown when each-way is selected.
Selection Name & Odds – Each of the 4 individual selections and their quoted odds.
Result – Whether each selection won, placed, was void (non-runner), or lost.
💰 Understanding the Results
| Result Field | What It Means |
|---|---|
| Total Bets | 11 for win-only, 22 for each-way, reflecting the full Yankee structure |
| Total Staked | Your stake per bet multiplied by the total number of bets |
| Winning Combinations | How many of the 11 doubles/trebles/fourfold bets returned a win |
| Total Return | The combined return across all winning, placed, and void bets |
| Profit / Loss | Total return minus total staked |
The bet breakdown table lists every one of the 11 combinations individually, showing exactly which selections were involved, whether that specific combination won, and what it returned.
A Yankee can still show a net profit even with two losing selections, since the surviving doubles among the remaining winners can outweigh the losses.
Void selections don’t kill a combination outright — a treble containing one void leg simply reduces to a double using the two remaining selections’ odds, matching standard bookmaker settlement rules.
Understanding how void legs reduce a bet’s fold, rather than cancelling it entirely, is key to correctly predicting Yankee returns around non-runners.
📐 Calculation Formulas
| Bet Component | Count / Formula |
|---|---|
| Doubles | 6 combinations of 2 selections from 4 (C(4,2)) |
| Trebles | 4 combinations of 3 selections from 4 (C(4,3)) |
| Fourfold Accumulator | 1 combination of all 4 selections |
| Place Odds (each-way) | (Decimal Odds − 1) × Place Fraction + 1 |
Each winning combination’s return is simply the stake per bet multiplied by the product of the decimal odds (or place odds) of every non-void selection included in that specific combination.
A Yankee’s 11 bets mean every possible pair, triple, and full combination of your 4 selections is automatically covered by a single bet slip.
When a selection is void, it’s simply dropped from every combination it appears in, and those combinations settle at the reduced fold using the remaining winning selections’ odds.
📝 Practical Examples
Example 1: All 4 selections win at odds of 2.50, 3.00, 4.00, and 5.00 (decimal). Every one of the 11 bets wins, including the big fourfold accumulator, producing a substantial total return relative to the stake.
Example 2: Three selections win and one loses. All 6 doubles and 4 trebles involving only winning selections would need to exclude the losing one — in practice, only the single double formed by the two winners not involving the loser survives, alongside any combination entirely made of winners.
Even with one losing selection in a 4-leg Yankee, several winning combinations can still exist among the remaining winners.
Example 3: One selection is declared a non-runner (void). Every combination containing that selection reduces by one fold — a treble becomes a double, and the fourfold accumulator becomes a treble using the three remaining selections.
A single void selection can quietly convert what looked like a losing fourfold into a still-winning treble.
💡 Tips & Best Practices
Always double-check your total staked figure before placing a Yankee — it’s easy to underestimate since 11 (or 22 each-way) bets at even a small stake per line adds up quickly.
Consider each-way Yankees for events with generous place terms, since they add meaningful extra winning combinations at the cost of doubling your total stake.
Review the full bet breakdown table rather than just the headline profit figure, to understand exactly which combinations are driving your result.
- Track void/non-runner rules carefully, since they can meaningfully change which combinations still stand a chance of winning
- Compare a Yankee against a straightforward fourfold accumulator if you want to understand the value of the extra doubles and trebles coverage
Remember that a Yankee requires at least two winning selections among surviving (non-void) legs to return anything at all.
Yankees reward picking several likely winners over one long-shot accumulator, since partial success across the 11 bets still produces a return.

⚠️ Common Mistakes to Avoid
Underestimating Total Stake
Treating the “stake per bet” figure as the full cost of a Yankee is a common and costly mistake, since the real total is 11 times that figure (22 for each-way).
Confusing stake-per-bet with total stake is one of the most frequent and expensive errors new bettors make with system bets like the Yankee.
Always multiply your stake per bet by 11 (or 22 each-way) before committing to the bet.
Assuming a Void Selection Kills All Related Combinations
A void or non-runner selection doesn’t automatically lose every combination it’s part of — it simply drops out, reducing a treble to a double or the fourfold to a treble.
Always check your bookmaker’s specific non-runner rules, though most follow this standard reduction approach.
Needing All 4 Selections to Win for a Profit
Unlike a straight fourfold accumulator, a Yankee can still return a profit with only 2 or 3 winning selections, thanks to the doubles and trebles coverage.
Treating a Yankee like an all-or-nothing accumulator misses its entire structural advantage over a single fourfold bet.
Always evaluate potential partial-winner scenarios, not just the full-clean-sweep outcome, when weighing up a Yankee.
Ignoring Place Terms When Backing Each-Way
Forgetting to check the actual place fraction and number of places paid for the specific event can lead to inaccurate expectations for the place part of an each-way Yankee.
Always confirm the exact each-way terms offered before placing the bet, since they vary by sport, field size, and bookmaker.
🎯 When to Use This Calculator
Use this calculator any time you’re placing or reviewing a Yankee bet and want to see the exact bet-by-bet breakdown across all 11 combinations, including how void selections affect the result.
System bettors who understand exactly how their doubles, trebles, and accumulator interact tend to make much better-informed staking decisions.
It’s especially useful for modeling different outcome scenarios before the event, so you know your realistic range of results in advance.

❓ Frequently Asked Questions
How many bets are in a Yankee?
A Yankee consists of 11 total bets: 6 doubles, 4 trebles, and 1 fourfold accumulator, all built from the same 4 selections.
Backed each-way, this doubles to 22 total bets, since each of the 11 combinations gets a separate win part and place part.
What happens if one of my 4 selections is a non-runner?
The void selection is removed from every combination it would have been part of, and those combinations settle at a reduced fold — a treble becomes a double, and the fourfold becomes a treble.
This is the standard bookmaker approach and generally works in the bettor’s favor compared to voiding the entire combination outright.
Can I profit from a Yankee with only 2 winning selections?
Yes — if 2 selections win and 2 lose, the single double formed by exactly those two winners can still return a profit, depending on the odds involved.
This partial-winner flexibility is the core advantage a Yankee has over a straight fourfold accumulator.
Is an each-way Yankee worth the extra stake?
It depends on the field size and place terms offered — generous place terms with several paid positions can make each-way coverage valuable, while poor place terms may not justify doubling your stake.
Compare the win-only and each-way results side by side using this calculator before deciding.
How does a Yankee differ from a Super Yankee?
A Yankee uses 4 selections for 11 bets, while a Super Yankee (also called a Canadian) uses 5 selections for 26 bets, adding more doubles, trebles, and fourfolds plus a fivefold accumulator.
The extra selection in a Super Yankee significantly increases both potential coverage and total stake required.

The void settlement explanation here is spot-on, but operators need to ensure their T&Cs explicitly state how reduced-fold bets are handled. I’ve seen disputes arise when punters assume a void leg cancels the entire bet rather than just reducing it to the next lower fold. Under UKGC guidelines, bookmakers must provide clear settlement rules before the bet is accepted. When you’re operating in multiple jurisdictions—Ontario, Malta, UK—each has slightly different void settlement precedents. The MGA’s position differs marginally from the UKGC on whether a non-runner in a Yankee should trigger stake return versus reduced-odds settlement. For compliance purposes, operators really need geolocation checks that trigger the correct T&Cs for each user. I’d recommend any operator offering Yankee or system bets document the void reduction formula (not just stating it verbally in support) and display it at bet placement, not buried in page 47 of terms. AML teams should flag accounts placing unusually complex Yankees across multiple selections as potential structuring patterns, especially if combined with frequent cash-outs below reporting thresholds. The calculator itself appears sound mathematically, but the real compliance risk sits in how each operator’s settlement system actually processes voids when the bet slip hits their backend—that’s where I’d audit first.
Regarding the jurisdiction-specific settlement rules you’ve flagged, you’re absolutely correct that this is where operational friction typically occurs. The MGA’s Technical Directive on system bets (updated 2023) does specify that reduced-fold settlement must be applied consistently across all bet types, but their guidance still leaves room for operator interpretation on timing—whether the void is processed at placement or at settlement. The UKGC’s approach is stricter: operators must communicate settlement outcomes within their system messaging before the bet is live. One practical detail worth noting for compliance teams: when a Yankee contains a non-runner, some operators process it as an immediate partial stake return plus reduced-odds settlement on the surviving combinations, while others hold the full stake and only settle after event completion. These approaches have different KYC implications if the customer disputes the settlement. The key audit point you mentioned—backend settlement logic versus front-end calculator display—is exactly where we see compliance gaps. We’ve documented cases where the calculator showed one outcome but the settlement engine returned another due to how the operator’s system ranked void priority across multiple legs. For operators managing cross-jurisdictional players, maintaining separate settlement rule sets per geolocation is essential, but equally important is testing that your backend correctly routes to the right ruleset when a player moves between regions or uses a VPN. Would recommend treating void settlement as a dedicated compliance test case rather than bundling it with general bet settlement QA.
