What the offer is worth
A cash-out figure is not a mystery: it is stake × original price ÷ current price, less the operator’s margin. This page shows the formula in full, works it through three market states, separates the fair value from the offer, and puts both next to the benchmark that actually matters — what the bet returns if you simply let it settle.
01The formula in full
Two lines do the work. The first is the fair value: stake × original price ÷ current price. The second is the offer: fair value − operator margin. Everything else about pricing is commentary on how the current price and the margin are set.
Read the first line as a comparison of prices. When the current price is lower than your original price, the selection has shortened — it is more likely by the market’s reckoning — and the fair value is above your stake. When the current price is higher, the selection has drifted, and the fair value is below your stake. When the two are equal, the fair value is exactly your stake, and the offer is below it by the margin alone.
Why divide by the current price
The fair value asks: what stake, at today’s price, would return the same as the potential return of this position? The potential return is stake × original price (in decimal-odds terms), and dividing that by the current price gives the equivalent stake today. That equivalent is what the position is worth.
02The margin, and why it is always there
The margin is the operator’s fee for closing the bet early, and it is applied after the fair value is worked out. It is not waived when the position is near its starting value, and it is not a penalty — it is the price of the service. In effect the operator quotes you a buy-back slightly worse than the fair value of the position, and the difference is what it keeps.
A margin expressed as a percentage moves the offer by that share of the fair value, so it is largest in money terms exactly when the position is worth most. That is worth remembering before pressing the button on a position that has shortened a long way.
Because the margin is a percentage of the fair value, a position worth £133.33 will lose more to the margin in pounds than a position worth £50, even at the same rate. The cost of the early exit scales with the value of what you are exiting.
03Three worked examples on the same bet
One £100 bet backed at 2.00, examined at three prices. The operator’s margin is taken as five per cent for illustration; every figure below is arithmetic you can check on a calculator.
| Market state | Fair value | Offer | If you take it | If you let it settle |
|---|---|---|---|---|
| Shortened to 1.50 | £133.33 | about £126.67 | Take about £26.67 profit now | Win £100 profit or lose £100, on the result |
| Flat at 1.98 | £101.01 | about £95.96 | Lock in about £4.04 loss | Win £100 profit or lose £100, on the result |
| Drifted to 4.00 | £50.00 | about £47.50 | Take about £52.50 loss now | Win £100 profit or lose £100, on the result |
Read across the last column: from the position’s point of view nothing has changed about the potential result. Only the market’s view of it has moved, and that is what the offer prices.
04Compared with letting the bet settle
The honest benchmark for a cash-out is not the stake — it is the alternative, which is letting the bet run. A cash-out swaps a range of outcomes for a single certain one, and the offer is the price of that swap. Comparing the offer with the potential return shows what you give up; comparing it with the stake shows what you lock in.
Neither comparison says which is right. The point is that the decision is a trade between a certain amount now and an uncertain amount later, and the arithmetic of that trade — not the label on the button — is what you are actually weighing.
| Number | What it is | Where it comes from |
|---|---|---|
| Offer | A certain amount now | Fair value less the operator’s margin |
| Potential return | An uncertain amount later | Stake × original price, if the bet wins |
| Stake at risk | What is lost if it runs on and loses | The amount still live after any partial exit |
Partial cash-out
How the same arithmetic applies to a slice of a position, leaving the rest live.
Affiliate disclosure and risk warning
Every affiliate link on this page and in the header is a sponsored link to a partner operator, and we may be paid if you open an account through it, at no extra cost to you. That link pays us; it does not improve any decision, it is not a ranking, and it is never a recommendation to play. Nothing on this page is betting, financial or tax advice, and nothing here is a prediction about any event or market, or a view on any operator. 18+ only. Every stake is money at risk and can be lost in full. The mechanics explained here — how a cash-out offer is priced from the position and the current market, why the offer sits below the fair value of that position, how a partial cash-out splits a bet, when the offer is withdrawn, how auto cash-out and bet insurance differ from a manual cash-out, and what accepting an offer does to the original bet and the ledger — are general descriptions of how those mechanisms usually work, not a statement of the terms, prices or rules that apply to you: the arithmetic, the availability and the terms of a cash-out differ between operators, markets, sports and jurisdictions and change over time, and an offer you accept is priced by the operator, not by this site. This page does not name any operator and is not a substitute for the operator’s terms or advice from a qualified adviser. Nothing here is a way to guarantee an outcome, a way to turn a cash-out into free money, or a way around any operator’s terms, any self-exclusion or any law. Never stake money you cannot afford to lose, never borrow to play, and never chase losses with a larger stake.
