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.

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.
π 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.
π’ 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.
π° 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 Γ 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.
π 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 Γ OddsA Γ OddsB | Β£0 (double requires both) |
| Single Stakes About | 2 Γ Stake Γ OddsA Γ OddsB | Β£0 (both legs fail) |
| Two Separate Singles | Stake Γ OddsA + Stake Γ OddsB | Stake Γ 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.
π Practical Examples
Example 1: A bettor stakes Β£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 Γ Β£20 Γ 6.0 Γ 4.0 = Β£960.00, for a profit of Β£920.00 on a Β£40 outlay.
Example 2: Using the same odds, if only Selection A wins and Selection B loses, the entire Β£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 Β£10 per leg on two short-priced favorites at 2/1 (decimal 3.0) each. If both win, return = 2 Γ Β£10 Γ 3.0 Γ 3.0 = Β£180.00, profit Β£160.00 on a Β£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.
π‘ 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.
β οΈ 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.
π― When to Use This Calculator
Use this calculator when considering a traditional Roundabout bet on two horse racing selections you’re strongly confident in, particularly across separate races on the same card.
The Single Stakes About rewards conviction on two selections at once, offering a larger payout in exchange for accepting an all-or-nothing structure.
It is not suitable for hedging strategies or situations where a partial return on one correct selection is desired.

β 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, Β£20 per leg on two selections means Β£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.
