Cash Out Bet Calculator
How To Use This Calculator
Enter your original bet, the current odds, and the book's offer. The calculator devigs the current market, works out the fair value of your position, and shows how far from it the offer sits.
The original stake and odds. For a parlay, use the combined odds of all legs.
The odds on your bet winning right now, plus the odds against it so the vig can be removed.
Type in the cash out offer and see the percentage it sits above or below fair value.
How Books Price a Cash Out
A cash out offer is a price, not a favor. The book estimates the current probability of your bet winning, multiplies it by your potential payout, and takes a slice off the result, the same way it builds margin into any other market.
Fair value is that calculation without the slice: current win probability times potential payout. This calculator estimates the probability from live odds, removes the vig when you enter both sides of the market, and puts the offer next to the number it should be judged against.
Worked Example: Is the Offer Fair?
You staked $100 at 4.0 before the match. Your team leads, and the market now prices your bet at 1.50 to win with 2.75 against. The book offers $235 to cash out.
When Cashing Out Makes Sense
On raw expected value, cashing out usually costs you money. The offer tends to sit below fair value because the book prices its own margin into it, so every accepted offer gives up a slice of your position. If long-run EV is all you care about, the default is to let bets ride.
Bankroll reality can override that. When a bet is a large share of your bankroll, a guaranteed amount now can be worth more to you than a slightly larger expected amount later. That is a variance decision rather than a value one, and it is legitimate: professionals reduce variance all the time, they just insist on doing it at a fair price.
Before accepting any offer, compare it with hedging: betting the other side of your position at another book or an exchange. Because you can shop for the best price on the hedge, it often beats the single number your book quotes. The hedge calculator does that math for you.
Why Devig the Current Odds?
The odds on your bet contain the book's margin, so reading them at face value overstates your win probability and inflates the fair value. Entering the odds against your bet lets the calculator strip that margin out with the multiplicative method, the same idea behind our no-vig calculator. With one side only, the calculator still works, but it flags that the probability is the book's padded number rather than a clean market estimate.
Common Mistakes to Avoid
An offer above what you staked can still be a bad deal, and one below it can be fair. The only meaningful comparison is against the current fair value of the position: probability times payout.
Using one-sided odds keeps the book's margin inside your probability estimate and inflates the fair value. Enter both sides of the current market whenever prices exist.
The cash out is one quote from one book. Betting the other side of your position elsewhere can settle it at a better effective price. Compare both exits before accepting.
A scary moment in the game moves the odds, and the offer follows them with the margin still attached. Decide with the numbers: fair value, offer, and the hedge alternative.
Frequently Asked Questions
How do sportsbooks calculate cash out offers?
The standard approach is to estimate the current probability of your bet winning, multiply it by the potential payout, and reduce the result by a margin. The exact margin varies by book and market, which is why it is worth comparing each offer against a devigged fair value.
What is the fair value of a cash out?
Fair value is the current win probability of your bet multiplied by its potential payout. When you enter the current odds on both sides of the market, the calculator removes the bookmaker's margin first, so the probability reflects the market's view rather than the book's padded price.
Is cashing out a bet ever worth it?
On expected value alone, usually not: offers commonly sit below fair value, so each cash out gives up a slice of EV. It can still be reasonable when the bet is a big share of your bankroll, when you need the money, or when new information has turned the position against you.
Why are cash out offers usually below fair value?
A cash out is a product the book prices with its own margin, like any other market. The offer is typically the current value of your position minus that margin, so it lands below what the position is worth. The gap is the price of settling early.
Does this calculator work for parlay cash outs?
Yes. Enter the parlay's combined odds as the original odds and the current combined odds of the remaining legs as the current odds. If a price against the parlay exists, add it to devig; otherwise the calculator uses the single-sided implied probability and flags it.
What does devigging the current odds do?
Bookmaker odds on both sides of a market imply probabilities that add up to more than 100%; the excess is the vig. Devigging strips it out to estimate the true win probability, which gives a more honest fair value than reading one side's odds at face value.
Can a cash out offer be above fair value?
It happens, usually when the book's cash out pricing lags a fast-moving market or its odds have gone stale. The calculator flags it: an offer above the devigged fair value locks in more than the position is currently worth.
Is hedging better than cashing out?
Often, when another book or an exchange prices the other side of your bet well. Hedging means betting against your own position at the best available odds, so you choose the price instead of accepting the one your book quotes. The hedge calculator shows the exact stake and what each exit locks in.
Judge the offer against the sharp price, not the book's
A cash out quote comes from the same book that priced your bet, margin included. Before accepting one, check what sharp books say your position is worth: devig their current odds and compare. Bet Hero tracks live prices across more than 400 bookmakers in real time, so you can see whether the offer, a hedge, or letting the bet ride is the best exit.
