Reverse Bet Calculator

This reverse bet calculator works out your profit in dollars on a two-team if-bet reverse, using American odds first. Enter both picks and a unit stake to see the net result whether both, one, or neither leg wins.

What Is a Reverse Bet?

A reverse bet is two if-bets running in opposite orders. An if-bet stakes on the first pick and only moves the money onto the second pick if the first one wins. A reverse pairs that if-bet with its mirror image, so you place both “if Pick A then Pick B” and “if Pick B then Pick A” at once, using two unit stakes.

The appeal of a reverse bet is risk control. Because the second stake in each if-bet is only placed once the opening pick has won, you never risk the full second wager on a leg that never gets action. If the first pick in one of the two if-bets loses, that if-bet stops right there - the stake for the second pick was never placed. This separates a reverse from a straight parlay, where a loss on either leg wipes out the whole ticket.

A reverse bet is a staple way for US bettors to link two picks while capping the downside a parlay would expose them to. It costs more upfront, since it commits two if-bets instead of one, but it softens what happens when only one pick comes in. The calculator below lets you enter both picks’ American odds and your unit stake, then see how the reverse plays out under each result.

How the Reverse Bet Is Calculated

A reverse bet is built from two if-bets, each carrying its own unit stake, so the total amount at risk is two units. If both picks win, each if-bet pays out on both legs, and their profits are added together for the overall result. If only the first pick in one of the if-bets wins, that if-bet nets its profit on the first leg minus the onward stake placed on the second pick and lost. If the first pick in an if-bet loses outright, only that opening stake is lost - the second unit was never placed, since an if-bet only moves money onto its second pick once the first one has won. The two if-bets are then added together for the overall result.

Converting the American odds to decimal odds is part of working out each leg’s return. For a plus-money pick like Pick A at +120, divide the American odds by 100 and add 1, which gives decimal odds of 2.20. For a minus-money pick like Pick B at -110, divide 100 by the American odds, ignoring the minus sign, and add 1, which gives decimal odds of 1.91. Once each pick has a decimal odds figure, the calculator works out what each if-bet pays when its picks land, and combines both if-bets’ results into the net figures shown below.

What the Calculator Shows You

Once you enter both picks’ American odds and your unit stake, the calculator returns the net result for every way the reverse bet can play out. It shows the net profit if both picks win, the best outcome the reverse bet can produce. It also shows the net result if only the first pick of one if-bet wins while the other if-bet’s opening pick loses, and the mirrored case where the other if-bet’s first pick wins instead. Finally, it shows the net result if neither pick wins - the full amount at risk across both if-bets. Reading these four outcomes together shows how much cushion the reverse bet gives you compared with risking the same two picks as a single all-or-nothing wager.

Worked Example

Take a reverse bet on two picks - Pick A at +120 and Pick B at -110 - with a $50 unit stake, so $100 is at risk across the two if-bets.

Pick A’s +120 converts to decimal odds of 2.20. Pick B’s -110 converts to decimal odds of 1.91. The reverse places “if Pick A then Pick B” and “if Pick B then Pick A” at the same time, each with its own $50 unit stake.

If both Pick A and Pick B win, the two if-bets together net $210.91 in profit - the best possible outcome, since both if-bets pay out on both of their legs.

If only Pick A wins and Pick B loses, the reverse bet nets minus $40.00. That loss is far smaller than losing the whole $100 at risk, because Pick B’s onward stake in the “if Pick A then Pick B” if-bet is only placed once Pick A has already won, while the “if Pick B then Pick A” if-bet loses only its opening stake when Pick B loses.

If only Pick B wins and Pick A loses, the reverse bet nets minus $54.55, following the same logic in the other direction.

If neither pick wins, both if-bets lose their opening stakes, and the reverse bet nets minus $100.00 - the full amount at risk.

This example shows why bettors choose a reverse bet over one straight wager on the same two picks: a single losing pick costs $40.00 or $54.55 rather than the full $100.00, while a clean sweep still returns a healthy $210.91 profit.

Reverse Bet Net Result on a $50 Unit ($100 at Risk)

The table below lays out the same four outcomes from the worked example above, using American odds of +120 for Pick A and -110 for Pick B, a $50 unit stake per if-bet, and $100 total at risk. Both picks winning is the only outcome that produces a profit; a single winning pick still cuts the loss well below a wipeout, and only a loss on both picks costs the full stake.

The Two Picks in Each Odds Format

Pick A and Pick B from the worked example are shown here in American odds, decimal odds, and implied probability side by side. Pick A’s +120 converts to 2.20 in decimal terms and implies a 45.5% chance of winning, making it the underdog. Pick B’s -110 converts to 1.91 and implies a 52.4% chance of winning, making it the favorite.

The If-Win-Only Variant and Its Trade-Offs

The reverse bet exists to soften the sting of a split result. A two-team parlay on the same two picks loses everything the moment either leg loses; a reverse bet loses only part of the stake, because the onward stake on the dead leg was never placed. That protection is why the single-winner outcomes in the table above are modest losses of $40.00 and $54.55 rather than the full $100.00 wipeout a parlay would produce.

The trade-off is cost and ceiling. A reverse bet commits two stakes instead of one, so more money is at risk up front than a single wager on either pick alone. And while the both-win profit of $210.91 is healthy, it is capped below what a true two-team parlay on Pick A and Pick B would pay from the same $100 outlay, since a parlay concentrates the full stake on one bet instead of splitting it across two if-bets.

This calculator models the common “if win only” variant, where the second leg of each if-bet triggers solely when the first leg wins outright. Some sportsbooks also offer “if win or push” action reverses, which move the second stake into action on a tie too. That variant changes the single-leg math shown above, so it’s worth checking which rule your book uses before comparing these numbers against a real ticket.

When a Reverse Bet Makes Sense

A reverse bet makes the most sense when you like two picks roughly equally but want to avoid the all-or-nothing exposure of a straight parlay. Because each if-bet only puts its second stake into action once the first pick has won, a reverse bet turns a single bad leg into a partial loss rather than a total one - as the worked example above shows, a $100 total risk becomes a loss of just $40.00 or $54.55 if only one pick comes through.

That protection comes at a cost, so a reverse bet is not automatically the right choice. You are committing two stakes instead of one, and the both-win payoff is capped below what the same two picks would return as a parlay. Bettors chasing the largest possible payout may prefer a parlay, accepting the all-or-nothing risk for a bigger reward. A reverse bet suits a more risk-averse approach: linking two picks while absorbing a smaller loss on a split result rather than risking the full stake.

Bankroll size matters too. A reverse bet ties up two unit stakes rather than one, so it uses more bankroll per bet than a single if-bet or a straight wager on one pick. It is also worth checking whether your sportsbook runs “if win only” or “if win or push” rules, since that affects how much protection the reverse provides on a tied leg.

Common Mistakes

One common mistake is thinking a reverse bet risks only one stake, when it commits two if-bets and two unit stakes. Another is expecting parlay-sized returns, when the structure that limits the downside also caps the upside compared with a parlay on the same two picks. Bettors also overlook whether their sportsbook runs an “if win” or an “if win or push” reverse, which changes how a tied leg is treated. Finally, it’s easy to confuse a reverse bet with a Single Stakes About bet, but the conditional logic behind each is different, so the two are not interchangeable.

Reverse Bet vs a Two-Team Parlay

A reverse bet and a two-team parlay link the same two picks but handle risk differently. A parlay is a single bet that pays more when both picks win but loses everything if either leg fails. A reverse bet splits the action into two if-bets, costing an extra stake but limiting the loss when only one pick comes through.
