A Single Stakes About – also known as a “Roundabout” – is a traditional horse racing multiple bet involving two selections. Unlike a simple double, each selection’s stake and winnings only run onto the other if both legs come in.
Loading calculator...
The Single Stakes About Calculator works out exactly how much you stand to win, and just as importantly, how much you stand to lose, from this two-way running bet structure.
Because both legs have to land for either part of the bet to pay out, this wager type rewards strong conviction on two selections rather than hedging across several outcomes.
📊 How to Use the Single Stakes About Calculator
Start by choosing your odds format – fractional is the traditional format for this bet type in UK and Irish racing, though decimal and American are also supported.
Single Stakes About bets are almost always placed on two selections from separate races, so make sure both prices are current before calculating.
Enter the odds for Selection A and Selection B, then set your stake per leg. The calculator immediately shows your total outlay and a full breakdown of every possible outcome.
🔢 Calculator Fields Explained
Odds Format – the price format used for both selections: Fractional, Decimal, or American.
Selection A Odds – the price for the first selection in the bet.
Selection B Odds – the price for the second selection in the bet.
Stake per Leg – the amount risked on each of the two running bets that make up the wager.
Currency – the currency your stake and returns are displayed in.
💰 Understanding the Results
| Result Field | What It Means |
|---|---|
| Return If Both Win | Total money returned across both legs when both selections win |
| Profit (Both Win) | Net winnings after subtracting the total outlay |
| Total Outlay | Combined stake across both legs of the bet (2 × stake per leg) |
| Outcome Table | Return and profit/loss for every possible combination of results |
Unlike a standard double, a Single Stakes About only pays out on one specific outcome combination – both selections winning. Any other result loses the entire outlay.
If only one selection wins, both legs of a Single Stakes About lose completely – there is no partial return, unlike an each-way or place bet.
This bet only ever pays out when both selections win – there is no partial credit for getting one right. That single fact is the most important thing to understand before staking a Roundabout.
📐 Calculation Formulas
The payout structure differs sharply from a normal double bet, since a Single Stakes About effectively runs two reciprocal bets between the same pair of selections.
| Bet Type | Payout If Both Win | Payout If Only One Wins |
|---|---|---|
| Standard Double | Stake × OddsA × OddsB | £0 (double requires both) |
| Single Stakes About | 2 × Stake × OddsA × OddsB | £0 (both legs fail) |
| Two Separate Singles | Stake × OddsA + Stake × OddsB | Stake × Odds of winner only |
A Single Stakes About pays roughly double a standard double when both selections win, because two reciprocal legs both complete successfully.
This higher payout compensates for the fact that, unlike two separate singles, an SSA offers no partial return if only one selection comes in.
📝 Practical Examples
Example 1: A bettor stakes £20 per leg on Selection A at 5/1 (decimal 6.0) and Selection B at 3/1 (decimal 4.0). If both win, return = 2 × £20 × 6.0 × 4.0 = £960.00, for a profit of £920.00 on a £40 outlay.
Example 2: Using the same odds, if only Selection A wins and Selection B loses, the entire £40 outlay is lost – the running stake from A’s win never completed its journey onto B.
Because both legs must land, a Single Stakes About suits bettors with strong confidence in two separate results rather than a hedge across outcomes.
Example 3: A bettor stakes £10 per leg on two short-priced favorites at 2/1 (decimal 3.0) each. If both win, return = 2 × £10 × 3.0 × 3.0 = £180.00, profit £160.00 on a £20 outlay.
Shorter-priced selections still generate strong returns in a Single Stakes About, because the multiplier effect applies twice. This makes the bet appealing even without picking long-shot prices.
💡 Tips & Best Practices
Only use a Single Stakes About when you have genuine confidence in both selections, since there is no consolation return for getting just one right.
Check that Selection A and Selection B are from separate races or events – this bet type is designed for sequential settlement, not simultaneous markets.
Compare the potential return against two separate single bets on the same selections to understand the trade-off you’re accepting.
- Keep stake per leg modest until you’re comfortable with the all-or-nothing payout structure
- Record every SSA bet placed alongside its outcome for long-term review
Treat this calculator as a pre-bet planning tool, checking the full outcome table before committing any stake.
Reviewing the full outcome table before betting helps set realistic expectations for a bet type with no partial payouts.
Consider whether a standard double, which carries the same all-or-nothing structure at a lower payout multiple, might suit your risk appetite better.
⚠️ Common Mistakes to Avoid
Assuming a Partial Return Exists
Some bettors mistakenly expect a partial payout if one selection wins and the other loses.
There is no partial return in a Single Stakes About – if either selection loses, the entire outlay across both legs is gone.
Expecting a consolation payout on a single winner is the costliest misunderstanding of this bet type. Always confirm both legs need to land before staking.
Confusing It With a Standard Double
A Single Stakes About and a standard double are not the same bet, despite both requiring two winners.
A Single Stakes About stakes twice the outlay of a single double and pays out roughly double when both selections win.
Always check the Total Outlay field to confirm you’re staking the correct amount for this specific bet structure.
Ignoring Settlement Order
This bet type traditionally assumes the two selections are settled in sequence, not simultaneously.
Overlooking the Currency Field
Leaving the currency selector on the wrong denomination can cause confusion when comparing this bet against sportsbook slips shown in a different currency.

❓ Frequently Asked Questions
What is a Single Stakes About bet?
It’s a two-selection horse racing multiple where equal stakes run reciprocally between both selections, paying out only if both win.
For example, £20 per leg on two selections means £40 total staked, with a payout only triggered by both selections winning.
Why is it also called a Roundabout?
The name reflects the circular structure of the bet – money runs from Selection A to B, and separately from B to A, in a loop.
The “roundabout” naming comes from the reciprocal, circular flow of stake and winnings between the two selections.
This distinguishes it from a simple double, where money only ever flows in one direction through the bet.
Do I lose everything if only one selection wins?
Yes, both legs of the bet fail to complete if either selection loses, meaning the full outlay is lost.
Losing the entire stake on a single incorrect selection is the defining risk of this bet type. Bettors should weigh this carefully before staking.
How does this differ from placing two separate single bets?
Two separate singles pay out independently on whichever selection wins, while a Single Stakes About only pays if both win together.
The trade-off is a larger combined payout from the SSA when both land, against zero return for a lone winner.
Can I use this calculator for more than two selections?
No, the Single Stakes About is specifically a two-selection bet; three or more selections require a different multiple bet type such as a Patent or Trixie.
Entering more than two selections’ worth of data would misrepresent the actual payout structure of this specific wager.

The SSA structure really suits traditional racing punters who back their form guides religiously. I’ve been using Roundabouts for years on the Cheltenham Festival, particularly when I’m confident about a horse’s going preference and jockey combination across two separate races. The soft ground favors certain bloodlines, and when you spot that pattern twice on a card, the SSA makes perfect sense. The math checks out too—you’re essentially getting two reciprocal bets that both need to land, so the payout compensates for that all-or-nothing structure. What I appreciate about this calculator is it shows the total outlay upfront. Too many punters forget they’re staking £40 on a Roundabout, not £20, and then panic when Selection A wins but Selection B doesn’t return anything. That’s the trap with SSAs—no partial recovery like an each-way bet would give you.
Regarding your point on Cheltenham form and going preferences—you’ve identified something crucial that the calculator alone can’t capture. The SSA structure does reward conviction across two correlated selections, though worth noting that form guides and going analysis are only part of the equation. One thing many traditional racing bettors overlook with SSAs is that the reciprocal nature of the two legs means you’re not hedging at all; if you wanted insurance against one leg failing, you’d be better served by placing two separate singles. The payout difference you’re describing—roughly double a standard double when both win—is the mathematical compensation for that all-or-nothing design. That said, your point about total outlay awareness is spot-on. Bettors often think in terms of stake per leg rather than total liability, which creates behavioral blind spots. The calculator helps surface this, but it’s worth noting that GamCare and the UKGC’s safer gambling resources recommend punters always verify their total outlay matches their intended bankroll allocation before confirming any wager.
Appreciate that breakdown on hedging. You’re right that I sometimes conflate SSAs with two separate singles in my head because the payouts look similar, but the mechanics are completely different. I’ve been caught out before backing a 6/1 shot as the second leg on an SSA when I should’ve just done two singles instead—the long shot hit but only after the favorite failed, so I got nothing. This calculator would’ve forced me to see that risk profile upfront.
That’s a valuable lesson that many racing punters learn the hard way. The behavioral advantage of using a calculator before wagering is exactly that—it visualizes the outcome matrix before you commit funds. Specifically, if you’d entered that 6/1 shot (decimal 7.0) as the second leg against a favorite, the calculator would display the zero return for ‘both win’ scenarios where only one leg completes. Some punters actually use this to inform their selection strategy: they’ll only use SSAs when they have two selections they’re genuinely confident about, and reserve mixed-odds combinations for two separate singles instead. This discipline around bet type selection is part of what UKGC research identifies as responsible bankroll management. Worth noting the calculator also supports currency selection, so whether you’re staking in GBP, EUR, or USD, the liability display remains transparent.
Hold on, this is about horse racing betting calculators, not slot games, but I gotta say the SSA concept reminds me of how bonus features work in high-variance Pragmatic Play slots. You need BOTH conditions to trigger for the full payout, otherwise you lose everything. Saw a streamer hit a Roundabout equivalent on Gates of Olympus last month where two separate bonus rounds had to connect, and the max win was absolutely mental when it landed. The SSA calculator here is definitely useful for racing bettors who know their form inside out, but the psychology is brutal—you’re chasing that double-leg hit and one miss tanks the whole thing. The odds displayed show why people gravitate toward short-priced favorites on SSAs; two horses at 2/1 each feels safer than mixing a 10/1 shot in there, even though the payout scales differently. This calculator’s outcome table breakdown is exactly what you need to see before you commit real money.
Interesting comparison between SSA mechanics and high-volatility slot bonus architecture—the all-or-nothing payout structure is genuinely similar in that respect. To clarify though: the SSA calculator here is specifically designed for horse racing two-selection bets, so the odds displayed will always be racing prices (fractional, decimal, or American formats). The psychological element you’re flagging about short-priced favorites on SSAs is actually well-documented in racing betting research. Two selections at 2/1 (decimal 3.0) each returns 2 × stake × 3.0 × 3.0 = 18× your total outlay, which feels more achievable than mixing a 10/1 shot, even though the EV calculation might favor the longer odds depending on true probability. Where the psychology becomes risky is that lower odds breed overconfidence—bettors see the lower variance and increase stake per leg accordingly, which can quickly consume bankroll. The calculator’s outcome table is definitely the most practical feature here because it forces users to confront the single losing scenario: both legs lose completely, every time, unless both selections win.
