A reverse bet is one of the most misunderstood betting systems around, precisely because its payout depends entirely on which of your two selections actually win. There’s no single “return” figure the way there is with a simple accumulator.

This calculator breaks a reverse bet into its four possible outcomes, so you can see exactly how much you stand to win, lose, or have staked in each case before you commit any money.
Understanding a reverse bet properly also means understanding its true liability. Because it runs two if-bets simultaneously in opposite directions, the maximum amount you can lose is larger than most bettors initially assume.
π How to Use the Reverse Bet Calculator
Enter your two selections, their decimal odds, and your unit stake. The stake is applied identically to every leg of both if-bets, since a reverse bet uses “single stakes about” staking, not a let-it-ride structure.
Every leg of a reverse bet uses the same fixed stake β winnings from an earlier leg are never carried forward into the next one.
The calculator then shows you all four possible results: both selections winning, either one winning alone, and neither winning, along with the stake actually placed and the profit or loss in each case.
π’ Calculator Fields Explained
Selection A Name – a label for your first pick, used to make the outcome breakdown easier to read.
Selection B Name – a label for your second pick.
Selection A Odds – the decimal odds for your first selection.
Selection B Odds – the decimal odds for your second selection.
Unit Stake – the fixed amount staked on every individual leg across both if-bets.
π° Understanding the Results
| Result Field | What It Tells You |
|---|---|
| Both Win | Return and profit when both selections land, triggering all four legs |
| Only A Wins | Return and profit when only the first selection lands |
| Only B Wins | Return and profit when only the second selection lands |
| Neither Wins | The guaranteed loss when both selections fail |
| Maximum Liability | The largest possible total stake exposure across all four legs |
Most bettors focus only on the “both win” scenario, since it’s the headline outcome being chased. But the single-winner scenarios matter just as much for understanding real risk.
A reverse bet’s worst-case loss is only two units, not four, because the second leg of each if-bet never triggers unless the first leg of that if-bet wins.
Maximum liability of four units only applies if you’re tracking total possible stakes placed across all winning legs, not the guaranteed downside.
This is the detail that trips people up most often: the four-unit figure is a ceiling on exposure, not the amount you automatically lose if things go wrong.
π Calculation Formulas
| Outcome | Stakes Placed | Return Formula |
|---|---|---|
| Both Win | 4 x Stake | 2 x (Stake x OddsA + Stake x OddsB) |
| Only A Wins | 3 x Stake | Stake x OddsA |
| Only B Wins | 3 x Stake | Stake x OddsB |
| Neither Wins | 2 x Stake | 0 |
The doubling in the “both win” formula happens because two independent if-bets, A-then-B and B-then-A, both complete successfully and both pay out in full.
Each if-bet is treated as fully separate; the calculator never nets one if-bet’s winnings against the other’s stake requirement.
π Practical Examples
Example 1 – Both selections win: $10 stake, Selection A at 2.5, Selection B at 3.0. Both if-bets complete fully: return = 2 x ($25 + $30) = $110, staked = $40, profit = +$70.
Example 2 – Only Selection A wins: Same odds and stake. If-bet(A-then-B) plays both legs (A wins $25, B loses), if-bet(B-then-A) plays only its opening B leg (loses). Return = $25, staked = $30, loss = -$5.
Even when one selection wins, a reverse bet can still finish at a net loss if that selection’s odds aren’t high enough to cover the three units actually staked.
Example 3 – Neither selection wins: Both opening legs lose immediately, no second legs ever trigger. Total staked = $20, total loss = -$20, well under the $40 maximum liability.
A total loss on a reverse bet is capped at just two units, half the maximum liability figure.
Example 4 – Long-shot pairing: $10 stake, Selection A at 6.0, Selection B at 8.0. If both win, return = 2 x ($60 + $80) = $280 against $40 staked, a profit of +$240.
π‘ Tips & Best Practices
Always check the “only one wins” outcomes before placing a reverse bet, since these are far more likely in practice than both selections landing together.
Use a reverse bet mainly when you genuinely rate two independent selections similarly, rather than as a way to inflate a single strong pick into a bigger-looking bet.
Compare the reverse bet’s total expected value against simply backing each selection as a straightforward single, since the system’s complexity doesn’t automatically make it better value.
- Confirm with your bookmaker whether they even offer if-bets or reverses as a bet type
- Check whether partial cash-out is available mid-way through the if-bet chain
Keep the unit stake modest relative to your bankroll, since the maximum liability figure represents real money at risk across four separate legs.
Run every outcome through the calculator first β a reverse bet only makes sense once you’ve seen all four scenarios side by side, not just the best case.
If you find yourself only ever checking the “both win” number, that’s a sign to slow down and look at the full outcome table before staking.
β οΈ Common Mistakes to Avoid
Assuming the maximum liability is the typical loss?
Bettors often see the four-unit maximum liability figure and assume that’s what they’ll lose if both selections fail.
Confusing maximum liability with the neither-wins loss overstates real risk by a full 100%, since the actual worst case is only two units.
Always check the “neither wins” row specifically rather than reading the liability figure as your downside.
Treating the four-unit maximum liability as the guaranteed loss is the most expensive misreading of a reverse bet.
Forgetting that each leg uses a fixed stake?
Some bettors expect winnings from the first leg to roll into the second, as with an accumulator, but a reverse bet does not work that way.
Expecting winnings to carry forward between legs leads to badly overestimating potential returns on a reverse bet.
Always remember the stake is fixed and identical across every leg, regardless of how much an earlier leg returned.
π― When to Use This Calculator
Use this tool whenever you’re considering a reverse bet across two selections and want to see the full range of outcomes before staking, rather than just the best-case combined return.
A system bet is only as good as your understanding of its worst outcome, not just its best one.
It’s also useful for comparing a reverse bet against simply placing two independent single bets on the same selections.

β Frequently Asked Questions
What is a reverse bet?
A reverse bet is a system combining two if-bets, one running A-then-B and the other running B-then-A, so that either selection winning first still triggers a payout chain.
For example, backing a football team and a tennis player as a reverse means either result winning first starts its own if-bet sequence.
How is a reverse bet different from a double?
A double requires both selections to win and pays out once; a reverse bet runs two separate if-bets and can produce a partial return even if only one selection wins.
A reverse bet effectively gives you two independent chances at a partial return, unlike a double’s all-or-nothing structure.
This is why reverse bets typically cost more to place than a simple double with the same stake per line.
Why does the calculator show four different outcomes?
Because a reverse bet’s actual return depends entirely on which selections win, there’s no single “expected payout” the way there is with a straight bet.
Showing all four scenarios lets you judge the system’s real risk-reward profile rather than only its best case.
Is a reverse bet the same as an each-way bet?
No. Each-way splits a single stake between a win portion and a place portion on one selection, while a reverse bet involves two separate selections and two if-bets.
They can technically be combined (each-way reverse), but that’s a more advanced variant not covered by this calculator’s base model.
Can I lose more than my unit stake times two?
Yes, potentially up to four times your unit stake, but only across scenarios where legs actually trigger and still lose β the guaranteed floor loss when neither selection wins is two units.
The “only one wins” scenarios sit between these two extremes depending on the odds involved.
