Cash out is worth it only when the offer is close to what your bet is worth at current prices, or when settling now matters more to you than the value you give up. A cash out offer is the bookmaker buying your bet back at a price it sets, and that price usually sits on the far side of fair, so on average taking one costs you money. The quick test: implied price = potential return / cash out offer, compared with the commission-adjusted price at which you could lay the same selection on an exchange.
Every cash out here is taken before the race jumps or the next game starts, and every price is illustrative. Hedging the bet yourself is the main alternative, and hedging bets covers it in full.
Cash out explained: a buyback at the bookmaker's price
A cash out settles your bet early for an amount the bookmaker names. Whatever happens next, you keep that amount and the bet is closed. In maths terms it is your bet plus a new bet against it with the same bookmaker, at a price the bookmaker chooses.
It is the bookmaker's option, not your right. A bookmaker decides which bets get an offer, can change the amount as prices move and can suspend or withdraw it before you accept. The Northern Territory's wagering regulator, the NT Wagering Commission, lists complaints about cash outs being removed or not offered among those it cannot investigate (checked October 2026). In Western Australia, the Rules of Wagering 2005 were amended so WA bookmakers may offer cash out on certain wagers once their systems are independently certified and the Gaming and Wagering Commission approves their terms (announced 19 June 2026). Read your own bookmaker's terms for when it offers cash out and what happens to a request that fails.
How is cash out calculated?
In outline, an offer is your potential return divided by the selection's current price, less a margin, so every offer turns back into a price. What matters is which side of fair that price sits on.
Example: illustrative prices, not a real race. You backed Runner 5 for $45 at $11.00 when the market opened, a potential return of 45 x 11.00 = $495. On race morning, before the jump, the exchange shows it at $4.90 to back and $5.10 to lay, you estimate its fair price at $5.00, and the bookmaker's own price for it is now $4.60.
Betfair true odds explains when an exchange midpoint like this $5.00 makes a fair estimate. At a fair $5.00 your bet is worth 495 / 5.00 = $99.00 on average. Valuing it at the bookmaker's own price gives 495 / 4.60 = $107.61, more than the bet is worth, because the bookmaker's price carries its margin. A buyback priced off that number would pay you more than fair, so the price behind a cash out normally sits on the other side: longer than fair.
A simple model shows the shape: offer = potential return / (fair price x 1.10), with an illustrative 10% loading on the price. For the same bet at different fair prices:
| Fair price now | Fair value of the bet | Offer at a 10% loading | Offer minus your $45 stake |
|---|---|---|---|
| $15.00, drifted | 495 / 15.00 = $33.00 | 495 / 16.50 = $30.00 | -$15.00 |
| $11.00, unchanged | 495 / 11.00 = $45.00 | 495 / 12.10 = $40.91 | -$4.09 |
| $8.00 | 495 / 8.00 = $61.88 | 495 / 8.80 = $56.25 | +$11.25 |
| $5.00 | 495 / 5.00 = $99.00 | 495 / 5.50 = $90.00 | +$45.00 |
| $3.00 | 495 / 3.00 = $165.00 | 495 / 3.30 = $150.00 | +$105.00 |
In every row the offer is 1 / 1.10, about 90.9%, of the fair value. An unchanged price hands back $40.91 on a $45 stake, and that $4.09 is the margin showing. Real offers follow the bookmaker's own prices and loading, so the 10% is a stand-in: the implied price is how you measure a real one.
Cash out vs hedge on the same bet
Take the $5.00 row: the bookmaker offers $90, which implies 495 / 90 = $5.50. The other exit is to lay Runner 5 on the exchange at $5.10. With your first bet at a bookmaker, the equal-result lay is potential return / (lay odds - commission rate):
- At an illustrative 5% commission: 495 / (5.10 - 0.05) = $98.02, a liability of 98.02 x 4.10 = $401.88. If Runner 5 wins: 450 - 401.88 = +$48.12. If it loses: -45 + 98.02 x 0.95 = +$48.12.
- At 7%: 495 / 5.03 = $98.41, a liability of 98.41 x 4.10 = $403.48, and +$46.52 either way: 450 - 403.48 if it wins, -45 + 98.41 x 0.93 if it loses.
The hedge calculator runs this sum for any bet, and lay betting explained covers liability if laying is new to you.
| Exit | If Runner 5 wins | If it loses | Expected profit given up | Held until the race settles |
|---|---|---|---|---|
| Keep the bet | +$450.00 | -$45.00 | $0.00 | Nothing |
| Lay at $5.10, 5% commission | +$48.12 | +$48.12 | 54.00 - 48.12 = $5.88 | $401.88 liability |
| Lay at $5.10, 7% commission | +$46.52 | +$46.52 | 54.00 - 46.52 = $7.48 | $403.48 liability |
| Cash out $90 | +$45.00 | +$45.00 | 54.00 - 45.00 = $9.00 | Nothing |
The $54.00 is the bet's expected profit at a fair $5.00: 99.00 - 45.00. To compare a cash out with a lay in one step, put both on the same footing:
commission-adjusted lay price = (lay odds - commission rate) / (1 - commission rate)
At 5% that is 5.05 / 0.95 = $5.32, and at 7% it is 5.03 / 0.93 = $5.41. The cash out implies $5.50, longer than both, so both lays leave you better off. The cash out would win only above about 8.9% commission: solving (5.10 - c) / (1 - c) = 5.50 gives c = 0.40 / 4.50 = 0.089. At 5%, it would need an offer above 495 x 0.95 / 5.05 = $93.12.
What the lay costs in practice is the $401.88 of liability held from your exchange balance until the race settles, plus the chance that it is not fully matched before the jump. The cash out needs nothing held.
Risk: Betting involves risk. The lay figures hold only if the whole lay is matched at $5.10 before the jump, the offer can change while you compare, and there is no guarantee of profit. See responsible gambling for limits and support.
A cash out is a new bet with its own margin
Taking the $90 gives exactly the result of keeping your bet and laying Runner 5 back to the bookmaker for $90 at $5.50:
| Result | Your $45 bet at $11.00 | Lay $90 at $5.50 | Total |
|---|---|---|---|
| Runner 5 wins | +$450.00 | -90 x 4.50 = -$405.00 | +$45.00 |
| Runner 5 loses | -$45.00 | +$90.00 | +$45.00 |
At a fair $5.00, a 20% chance, that new bet's expected value is 90 x (1 - 0.20 x 5.50) = -$9.00, the same $9.00 the cash out gives up against keeping the bet. The bookmaker prices the bet both ways: it would sell you Runner 5 now at $4.60 and buys yours back at $5.50. The cost of leaving early is the gap between the fair $5.00 and that $5.50 buyback.
Cash out on multis and same game multis
A multi can be offered a cash out between legs, once the earlier legs have won and before the next one starts. The same price test applies. A $15 multi returning $270 with one leg to go, offered $108, implies 270 / 108 = $2.50. If the last leg is $2.30 to lay, the commission-adjusted lay price at an illustrative 5% is (2.30 - 0.05) / 0.95 = $2.37. That is shorter than $2.50, so laying the last leg is the better exit; hedge a multi sizes that lay.
A same game multi has no exchange market to compare with: its legs sit in one game and are priced together. The one price you can check is the bookmaker's own, by rebuilding the same legs in a new bet slip. Say a $20 same game multi taken at $9.00 returns $180. Before the game, team news shortens the same legs to $6.50, and the cash out is $22.50, which implies 180 / 22.50 = $8.00. The bookmaker would sell that multi now at $6.50 and buys yours back at $8.00, a gap of 1 / 6.50 - 1 / 8.00 = 15.4% - 12.5% = about 2.9 percentage points of probability. Each bookmaker prices a same game multi with its own view of how the legs move together, so that gap is the only measure you have.
Risk: Betting involves risk. A lay beats the offer only if it is matched in full at your price before the last leg starts, the offer can change or be withdrawn while you compare, and a multi you keep can still lose. See responsible gambling for limits and support.
When cash out can make sense
A cash out usually costs you the gap to fair value, but some cases make it worth taking:
- No cheaper exit. A same game multi, an exotic leg or a market the exchange does not cover leaves cash out as the only way to settle early.
- A hedge you cannot use. The liability is more than your exchange balance, the amount is too small to lay, or your commission is high enough that the adjusted lay price is longer than the cash out's.
- A position that has grown too big. If a single bet carries more of your bankroll than you planned, a cash out, or part of one where offered, removes the swing at a known price.
- An offer above fair value. If Runner 5 drifted to a fair $6.00 on the exchange while the offer still stood at $90, the bet would be worth 495 / 6.00 = $82.50 and the offer 90 - 82.50 = $7.50 more. Do not count on one: an offer like this changes as prices update.
The decision rule: take a cash out when its implied price is shorter than both your fair price and the commission-adjusted lay price, or when you have no cheaper exit and want the risk gone. Keep the bet when you would back it again at today's price.
Risk: Betting involves risk. A fair price is an estimate, an offer can be withdrawn before you accept, and a bet you keep can still lose. See responsible gambling for limits and support.
Mistakes that make cash out expensive
- Judging the offer against your stake. $90 back on a $45 bet looks like doubling your money, but at a fair $5.00 the bet was worth $99.00, so the cash out gave up $9.00.
- Judging it against the bookmaker's own price. 495 / 4.60 = $107.61 is what the bet looks worth at the bookmaker's selling price, more than its worth at a fair $5.00.
- Leaving commission out of the comparison. A $5.10 lay is worth $5.32 once a 5% commission is counted, so compare the cash out with $5.32, not $5.10.
- Cashing out by habit. The margin repeats on every one: thirty cash outs at a $9.00 cost each give up 30 x 9.00 = $270 of expected value.
- Comparing with the exchange back price. Your exit is a lay, so the price that counts is the lay price, $5.10 ($5.32 once a 5% commission is counted), not the $4.90 back price.
Where B337 fits
The Terminal puts Betfair back and lay next to prices from 40+ bookmakers across racing and sports, with flucs showing how each price has moved. Those are the inputs for estimating a fair price and finding the lay price before you judge an offer. B337 is software, not a bookmaker, so it has no cash out to offer, and it does not place exchange bets: any cash out or hedge is yours to take, in your own accounts. The Terminal reads prices on a repeating cycle, so check both numbers with the bookmaker and the exchange before you act. A free account opens a limited view of the Terminal with live odds. Bookmaker names are trade marks of their owners. B337 is not affiliated with them.
Risk: Betting involves risk. A bookmaker's own price can be newer than the one on the Terminal, and a cash out or a hedge settles only at the figure actually accepted. See responsible gambling for limits and support.
