Best Odds Guaranteed: How BOG Payouts Work
Quick answer
Best Odds Guaranteed uses the better eligible price on a winning bet. Compare price taken with SP below, calculate the uplift and then check whether the offer applies.

Best Odds Guaranteed pays the better of the price you took and the official Starting Price. If you back a qualifying winner at decimal 4.00 and it returns a 6.00 SP, settlement uses 6.00. If it shortens to 3.00, you keep 4.00. The offer, race, time, market and customer must all qualify.
BOG does not mean the bookmaker will match the highest price available anywhere in the market. It compares two prices on your own qualifying bet: the fixed price recorded on the receipt and the Starting Price returned when the race begins.
The concession is common in UK and Irish racing, but eligibility is not universal. Current official help pages show different opt-in, product, timing, customer and payout conditions. Use this guide to verify the calculation, then use the terms displayed on your bet to decide whether BOG applies.
What Does Best Odds Guaranteed Mean?
Best Odds Guaranteed, usually shortened to BOG, protects a bettor from one specific type of adverse price movement. You can take a fixed price before the race. If the horse later drifts and the official SP is bigger, a qualifying winning bet receives the SP. If the price shortens, the fixed price remains.
Current official BOG help describes the offer as paying the bigger price when SP is higher. Another current sportsbook FAQ uses the same core comparison while applying its own opt-in, timing and eligibility rules. The mechanic is stable; the offer conditions are not.
BOG is not a cross-bookmaker price guarantee
The comparison is normally between the price on your qualifying receipt and the official SP. A larger price displayed by another bookmaker does not automatically change your settlement.
What Is the Starting Price?
The Starting Price is the official market price returned at the off. The Starting Price Regulatory Commission explains that British racing SPs are based on a race-by-race sample of qualifying bookmaker prices. Its rules define how the sample is selected and how the returned price is calculated.
SP is therefore not simply the last number shown by your bookmaker. It is an industry settlement reference. The Jockey Club racing glossary is useful for racing terminology, while the SPRC rules are the primary reference for the current British mechanism.
A BOG bet only benefits when the official SP is longer than the eligible fixed price after any applicable adjustment. If the SP is shorter or equal, the price taken already gives the same or better return.
Best Odds Guaranteed Formula
- Record the decimal price taken. Use the accepted bet receipt, not a later market screen.
- Record the official decimal SP. Confirm that an SP was returned for the selection.
- Use the higher eligible price. Settled odds = maximum of price taken and SP.
- Calculate return. Stake x settled decimal odds.
- Calculate the BOG uplift. BOG return minus the return at the eligible fixed price.
If your receipt uses fractional odds, convert both prices with the odds converter before checking the formula.
Compare the price before relying on BOG
Use the Sharkbetting Oddsmatcher to compare available prices before placing the bet. Then confirm BOG eligibility on the receipt because the tool cannot decide the offer terms.

The horse drifts and wins
You stake £20 at decimal 4.00. The horse returns an official SP of 6.00 and wins. A standard return at the price taken would be £20 x 4.00 = £80. BOG uses 6.00, so the return is £20 x 6.00 = £120. The BOG uplift is £40.
The horse shortens and wins
You stake £20 at decimal 6.00. The horse returns an SP of 4.00 and wins. The fixed price is already better, so settlement remains £20 x 6.00 = £120. The BOG uplift is £0.
The horse loses
The selection loses, so the fact that SP was bigger does not create a payment. BOG changes the odds used for an eligible winner. It does not insure the selection against losing.

How to Check Whether a Bet Qualifies
- Offer status: confirm BOG is active and available to your account.
- Opt-in: some current offers require an opt-in before the bet qualifies.
- Race and region: many offers focus on specified UK and Irish racing.
- Placement time: current examples often begin at a stated time on race day.
- Market: win and standard each-way markets may qualify while place-only, tote or special products do not.
- Funding and boost: free bets, tokens and enhanced prices can have separate treatment.
- Receipt confirmation: save the indicator showing that the accepted bet qualified.
For example, one current official BOG explanation requires an opt-in and lists exclusions including ante-post, in-running, place-only and some token-funded bets. Another current rulebook includes different products. The correct conclusion is not that one list is universal, but that qualification must be checked on the actual receipt.
BOG and Rule 4 Deductions
A non-runner can change the eligible fixed price before the BOG comparison. This is where a simple "take the higher number" explanation can fail. Current rulebooks do not all describe the interaction in the same way.
One current official help page says BOG can compare SP with revised odds after a Rule 4 deduction. Another current offer says BOG does not apply when a non-runner causes prices to revert to SP. Read the specific non-runner and BOG clauses before calculating.
Do not subtract Rule 4 from the final return twice. First identify the revised price or profit basis used by the published rule, then make the BOG comparison in the sequence that rule specifies. The Rule 4 calculator checks deduction arithmetic but cannot decide the operator's BOG sequence.
BOG on Each-Way Bets and Multiples
Current offers can include standard each-way bets. The higher eligible win price can affect both the win return and the place calculation, but the place fraction and number of paid places still come from the accepted each-way terms. Use the each-way betting guide for the two-part structure and the each-way calculator for standard returns.
Some current BOG offers also apply to qualifying multiples. Each eligible racing leg can be settled at the better allowed price before the combined return is determined. A non-qualifying leg does not become BOG simply because another leg qualifies.
Extra-place offers add another layer. The extra-place betting guide explains the place concession, which should be checked separately from the odds concession.
Ante-Post, In-Play and Special-Market Exclusions
Ante-post bets are commonly excluded because they are placed before the race-day BOG window and can carry all-in, run-or-not terms. Read the ante-post betting guide before assuming a long-range racing bet will receive SP protection.
In-play bets, tote or pari-mutuel products, place-only markets, forecasts and enhanced products are also common exclusion categories, but the exact list varies. The product label matters more than how similar the bet looks to a normal win selection.
Operators are expected to display the rules used to accept and settle bets. The Gambling Commission condition on displayed betting rules supports a simple audit habit: if the receipt says BOG, preserve it; if it does not, verify eligibility before relying on the concession.
How to Audit a BOG Settlement
- Confirm the bet was eligible. Check opt-in, account, race, time, market and funding conditions.
- Save the accepted price. Use the receipt rather than the price you remember seeing.
- Confirm the official SP. Use the settled race result and SP source.
- Check non-runner adjustments. Apply the published Rule 4 and BOG sequence once.
- Recalculate the return. Compare the price-taken return, BOG return and credited uplift.
- Check caps and special terms. A correct price calculation can still be subject to a published benefit cap.
Best Odds Guaranteed FAQs
A qualifying winning racing bet is settled at the better of the fixed price you took and the official Starting Price. If SP is shorter, you keep the better fixed price.
No. BOG normally compares the eligible price on your own bet receipt with the official SP. It is not a promise to match a larger price offered elsewhere.
Ante-post is a common exclusion because the bet is placed outside the race-day BOG window and can use all-in terms. Check the exact offer because eligibility is operator-specific.
A non-runner can revise the fixed price or change whether BOG applies. Current rulebooks describe different sequences, so use the BOG and non-runner clauses attached to the bet before comparing with SP.
Many current offers include qualifying standard each-way bets. The eligible higher win price can feed into the win and place calculations, while the accepted place fraction and places still control the place part.
Multiply the stake by the higher eligible price, then subtract the return at the eligible price taken. A £20 bet at 4.00 with a 6.00 SP returns £120 instead of £80, so the uplift is £40.
