If Bet / Reverse Bet Calculator

Calculate payouts for conditional if-bets, reverse bets, and action reverse bets. See every outcome scenario, compare against parlays and straight bets, and find your optimal structure.

If Bet: Bets are placed sequentially. Each subsequent bet is only placed if the previous bet wins or pushes. If any bet loses, the chain stops.

Straight bets put $200.00 at risk, the if bet $100.00, the parlay $100.00. The parlay needs all 2 legs and pays up to $377.27; the if bet pays up to $240.91 and stops as soon as a leg loses, which is what caps the downside at -$100.00. Expected value is not compared here: priced off the book's own numbers, all three structures come out at exactly zero, so any ranking would be reporting rounding noise.

Understanding If Bets & Reverse Bets

What is an If Bet?

An if bet is a conditional wager where the second bet is only placed if the first bet wins (or pushes). Your stake on the first bet, plus any winnings, rolls forward to fund the next bet in the sequence. If the first bet loses, the chain stops and no further bets are placed. This structure limits your total risk compared to betting every leg independently.

Example

You place a $100 if bet: Bet 1 at -110, if win then Bet 2 at +150. If Bet 1 wins, you collect $190.91 and $100 of that funds Bet 2. If Bet 2 also wins, total return is $340.91. If Bet 1 loses, you lose only the original $100 and Bet 2 is never placed.

Reverse Bets Explained

A reverse bet is simply two if bets running in opposite directions. For a two-leg reverse, you place If Bet A (Bet 1 then Bet 2) and If Bet B (Bet 2 then Bet 1) simultaneously. This costs twice the stake of a single if bet, but it means you have action on both legs regardless of which one wins first. If both win, you collect on both if-bet chains.

Example

$50 reverse bet: Path A is Bet 1 (-110) then Bet 2 (+120). Path B is Bet 2 (+120) then Bet 1 (-110). Total risk is $100. If both win, both paths pay out. If only one wins, one path pays while the other stops or loses.

If Bet vs Parlay

A parlay combines all bets into one — all legs must win for any payout. An if bet is sequential: each leg is resolved independently, and you can collect partial winnings if some legs win and others lose. Parlays pay more when all legs hit because the odds multiply, but an if bet protects you from total loss when only some legs win. The tradeoff: parlays offer higher ceiling, if bets offer lower floor.

Key Difference
Parlay: ALL must win → one payout (high risk, high reward)If Bet: sequential → partial payouts possible (moderate risk)Straight: independent → each resolves alone (lowest risk, most capital)

When to Use If Bets

If bets shine when you want action on multiple games but have a limited bankroll. Instead of tying up capital on separate straight bets, an if bet lets you use the same stake across a chain of wagers. They are also useful when you have one strong play and a secondary play you only want to risk house money on. Reverse bets are ideal when you cannot predict which game will finish first and want coverage regardless of resolution order.

When to Consider
  • Limited bankroll but want multi-game action
  • One strong play + one speculative play
  • Want partial-loss protection vs. parlay
  • Games finish at different times (use reverse)
