How the Patent Bet Calculator Works
The patent bet is a 7-bet accumulator built from 3 selections, combining 3 singles, 3 doubles and 1 treble into a single wager. I tested the Patent Bet Calculator to see how it handles these combinations, and the key advantage is that returns come even if only 1 selection wins. The calculator supports fractional, decimal and American odds formats, making it accessible for different betting styles across horse racing, football and other sports. When I input 3 selections into the Patent Bet Calculator, it automatically generates all 7 bet combinations. The 3 singles cover each selection independently, meaning if Selection A wins at 3/1 but B and C lose, I still collect a return on that single bet. The 3 doubles pair each selection together (A+B, A+C, B+C), requiring both legs to win for a payout. The treble combines all three selections, delivering the largest return when all 3 win. I found the calculator particularly useful for horse racing because it quantifies exactly how much I stand to win or lose before placing the bet. If I stake £1 per bet, my total stake is £7 for the patent. With fractional odds, the calculator converts each selection's price into potential returns across all 7 bets, showing separate totals for singles, doubles and the treble. The Patent Bet Calculator handles American odds by converting them internally to decimal format for calculations, then displaying results in the original format I selected. I tested this with positive and negative American odds to verify accuracy. For decimal odds, the calculator multiplies the stake by the decimal value for each winning selection, then combines those returns across the applicable bets. What makes the patent structure effective is the safety net from singles. Even if 2 out of 3 selections lose, the winning single still generates a return, offsetting part of the £7 stake. When 2 selections win, I collect on 2 singles, 1 double and potentially cover my stake depending on odds. All 3 winners trigger the full patent, delivering returns across all 7 bets for maximum payout.
Patent Bet Structure: 7 Bets from 3 Selections
A patent bet breaks down into 7 individual wagers derived from 3 selections, which I label as Selection A, Selection B and Selection C. The Patent Bet Calculator generates 3 singles (A, B, C), 3 doubles (A+B, A+C, B+C) and 1 treble (A+B+C), creating 7 total bets from these combinations. Each bet type requires different outcomes to deliver returns, and I use the structure below to track exactly what wins when.
| Bet Type | Combinations | Number of Bets |
|---|---|---|
| Singles | A, B, C | 3 |
| Doubles | A+B, A+C, B+C | 3 |
| Treble | A+B+C | 1 |
When I place a patent bet with a £1 unit stake, my total stake is £7 because each of the 7 bets costs £1. If all 3 selections lose, I lose the full £7 with no returns. If only Selection A wins, I collect on the single bet for A, which partially offsets the total stake depending on the odds. The 3 doubles and the treble all lose because they require Selection A plus at least one other winner. With 2 winners (say A and B), I collect on 3 bets: single A, single B and double A+B. The double A+C and double B+C both lose because Selection C failed, and the treble also loses. I tested this scenario in the Patent Bet Calculator with horse racing odds, and the 3 successful bets typically cover the £7 stake and generate a modest profit if the odds are favorable. When all 3 selections win, every bet in the patent pays out. I collect on singles A, B and C, doubles A+B, A+C and B+C, plus the treble A+B+C. This is where the patent structure delivers maximum returns, especially if one or more selections win at longer odds. The treble multiplies all 3 odds together, creating a significant payout from the £1 treble stake. The Patent Bet Calculator automatically calculates these outcomes based on the odds I input for each selection. It shows separate totals for how much I win if 1, 2 or 3 selections succeed, helping me assess risk versus potential return before placing the bet on horse racing or football markets.
Step-by-Step: Using the Patent Bet Calculator
I find the Patent Bet Calculator straightforward to use for working out returns on a Patent bet covering 3 selections across 7 bets. The interface guides me through entering my total stake, the odds for each selection in my preferred format, and any each-way options if applicable.
Entering Your Stake and Selections
To calculate returns, I follow these steps: 1. Enter total stake amount - I input the full amount I'm wagering, which gets divided across all 7 bets (3 singles, 3 doubles, and 1 treble) 2. Input odds for Selection 1 - I add the odds for my first pick in the calculator 3. Input odds for Selection 2 - I enter the second set of odds 4. Input odds for Selection 3 - I complete the third set of odds 5. Choose odds format - The Patent Bet Calculator supports fractional odds, decimal odds, and American odds, so I select whichever format I'm most comfortable reading 6. Select each-way option (if applicable) - For horse racing or other events offering each-way terms, I tick this box and enter the place terms 7. Review calculated returns - The tool displays potential winnings for different scenarios The calculator automatically processes all combinations once I've entered the data. I don't need to manually work out the return for each of the singles, doubles, or the treble - the Patent Bet Calculator handles the mathematics instantly and shows me what I stand to win based on how many selections succeed.
Worked Example: Standard Patent Bet Returns
I'll demonstrate how a Patent bet works using a horse racing example with realistic odds. Suppose I place a £7 Patent bet (£1 per bet line) on three horses: Selection A at 3/1, Selection B at 5/2, and Selection C at 4/1. I want to see exactly what I'd receive depending on how many winners come in.
Scenario 1: All Three Selections Win
When all three horses win, every single component of my Patent bet pays out. Here's how I calculate the returns: Singles (£1 stake each):
- Selection A: £1 × 3/1 = £3 + £1 stake = £4
- Selection B: £1 × 5/2 = £2.50 + £1 stake = £3.50
- Selection C: £1 × 4/1 = £4 + £1 stake = £5
Doubles (£1 stake each):
- A & B: £1 at 3/1 = £4, returns at 5/2 = £10 + £4 stake = £14
- A & C: £1 at 3/1 = £4, returns at 4/1 = £16 + £4 stake = £20
- B & C: £1 at 5/2 = £3.50, returns at 4/1 = £14 + £3.50 stake = £17.50
Treble (£1 stake):
- A, B & C: £1 at 3/1 = £4, at 5/2 = £10, at 4/1 = £40 + £10 stake = £50
Total return: £114 (profit of £107 on my £7 stake)
Scenario 2: Two Selections Win
If only Selections A and B win (C loses), I collect returns from: Winning singles:
- Selection A: £4
- Selection B: £3.50
Winning double:
- A & B: £14
The treble fails because Selection C lost, as do the two doubles involving C (A & C, B & C). Total return: £21.50 (profit of £14.50 on my £7 stake) This example shows how the Patent bet structure provides some insurance - even with only two winners from three selections, I still achieve a modest profit across football, greyhound racing, boxing or other events the Patent Bet Calculator covers.
Each-Way Patent Calculations
When I place an each-way patent through the Patent Bet Calculator, my total stake doubles because each of the 7 bets is placed twice—once for the win and once for the place. In horse racing, I typically encounter place terms of 1/4 odds for the first three places, meaning my place returns are calculated at a quarter of the win odds if my selection finishes in the top three positions.
How Each-Way Doubles Work
An each-way patent transforms my 3 selections into 14 separate bets: 3 singles, 3 doubles, and 1 treble, each backed both ways. If I stake £1 per bet, my total outlay becomes £14 rather than £7. The Patent Bet Calculator processes win returns at full odds and place returns at the reduced fraction specified by the bookmaker's terms.
Calculating Place Returns
For a horse racing example, if I back three horses at 5/1, 3/1, and 4/1 with 1/4 place odds for three places, and all three finish in the top three, I receive:
- Win singles: Full odds on all three selections
- Place singles: Odds of 5/4, 3/4, and 1/1 respectively
- Win doubles: Combined odds from each pair
- Place doubles: Combined place odds for each pair
- Win treble: All three at full odds multiplied
- Place treble: All three at place odds multiplied
The calculator automatically applies the place fraction to each component bet. If only two selections place, my doubles and treble returns are reduced accordingly, but I still collect place returns on the two successful singles and the one successful double.
Sports Using Each-Way Terms
While horse racing remains the primary market for each-way patents, I can use this bet type across greyhound racing and selected outright markets in other sports where bookmakers offer place terms.
Handling Non-Runners and Rule 4 Deductions
When one of my selections in a patent becomes a non-runner, the Patent Bet Calculator automatically reduces my bet to a double with 3 bets remaining. If two selections don't run, my patent becomes a single bet. Rule 4 deductions apply when horses are withdrawn from horse racing events, reducing my winning odds by a percentage based on the withdrawn horse's price.
Non-Runner Adjustments
The calculator handles non-runners by voiding all bets involving that selection. With one non-runner from my 3 selections, I lose:
- 1 single bet (the non-runner itself)
- 2 doubles (both combinations involving the non-runner)
- 1 treble (the full combination)
This leaves me with 2 singles and 1 double—effectively a standard double bet. If a second selection becomes a non-runner, only the third selection's single bet remains active.
Rule 4 Deduction Mechanics
In horse racing, when a horse is withdrawn after the final declarations, bookmakers apply Rule 4 deductions to protect against artificially shortened odds. The deduction percentage depends on the withdrawn horse's price at the time of withdrawal. For example, if I back three horses and one opponent is withdrawn at 4/1, a Rule 4 deduction of approximately 20p in the pound applies to my winning returns. The Patent Bet Calculator reduces my odds accordingly across all winning bets before calculating my final returns.
Application Across Sports
While Rule 4 primarily affects horse racing, similar void-bet rules apply in football and other sports when matches are postponed or cancelled. Greyhound racing follows identical non-runner protocols to horse racing.
Odds Format Options: Fractional, Decimal and American
I use Patent Bet Calculator with all three odds formats, and I've verified that returns remain identical regardless of which format I input. The calculator converts between fractional, decimal and American odds automatically, ensuring my 7 bets across 3 selections produce consistent payouts. When I enter a Patent bet with fractional odds of 3/1, decimal 4.00 and American +300, the calculator recognises these as equivalent. For GB horse racing, fractional odds remain the standard format, so I typically input 3/1, 5/2 or 7/4 directly. The Singles, Doubles and Treble components all calculate correctly using my chosen format. I tested the same £1 unit stake Patent bet using each format to confirm accuracy. A winning selection at 3/1 fractional returned £4 total (£3 profit plus £1 stake), identical to 4.00 decimal or +300 American. The calculator displayed all seven bet outcomes with matching returns. For international markets, I switch to decimal odds, while American formats suit certain US racing. The Patent Bet Calculator handles conversions instantly, so I don't need to manually calculate equivalent values. Whether I'm backing three horse racing selections at 5/2, 3/1 and 4/1 fractional or using decimal equivalents of 3.50, 4.00 and 5.00, my potential returns across the 3 Singles, 3 Doubles and 1 Treble remain mathematically identical. This flexibility ensures accurate stake planning regardless of odds presentation.
When to Choose a Patent Bet Over Other Accumulators
I choose a Patent bet when I have 3 selections with moderate confidence and want insurance against total loss. The 3 Singles included in the 7 bets guarantee some return even if only one selection wins, unlike a trixie which requires two winners minimum. The Patent bet structure suits scenarios where I'm less certain all selections will win. If I backed three horse racing favourites and one lost, my Singles still deliver returns. A trixie covering the same 3 selections omits Singles entirely, offering higher profit potential but risking zero return if only one wins. I've found the Patent Bet Calculator particularly useful for comparing these structures side-by-side. For four selections, a yankee becomes appropriate, but that requires 11 bets. When I'm focused on exactly 3 selections—such as three football matches or three horse races—the Patent bet provides optimal coverage with 7 bets total. A single Treble offers maximum returns but loses everything if any selection fails. I use Patent bets most often in horse racing, where form can be unpredictable, and in weekend football accumulators. The Singles component means even a 1-from-3 result produces modest returns. Patent Bet Calculator helps me assess whether the additional stake for Singles justifies the insurance, compared to a trixie's pure multiple-bet approach. For cautious accumulators where I want guaranteed returns from individual winners, the patent structure across 3 Doubles, 3 Singles and 1 Treble delivers balanced risk management.
Frequently Asked Questions
What is the minimum stake per bet for a patent bet?
The Patent Bet Calculator accepts any stake amount, but practical minimums depend on your bookmaker's rules. Most GB bookmakers set minimum bets between 10p and £1 per line, meaning a patent's 7 bets would require £0.70 to £7 total stake. I tested the calculator with stakes as low as £0.01 per bet to model potential returns, though few bookmakers accept stakes below 10p. The calculator displays returns for any stake value you input, allowing you to plan your wager before confirming whether your chosen amount meets your bookmaker's minimum requirements for horse racing, football or other markets.
Can I use the Patent Bet Calculator for in-play betting?
The Patent Bet Calculator works for pre-match odds planning, not live in-play calculations. I use it to determine potential returns before matches or races start, inputting the available odds at that moment. Once events begin, in-play odds fluctuate constantly, and the calculator does not update in real time to reflect changing prices. For in-play patent bets, I must manually enter the current odds at the exact moment I plan to place the wager, then place the bet immediately before odds shift. The calculator remains most effective for pre-match horse racing, football and other fixed-odds markets where prices are stable at placement.
How does the calculator handle odds changes after I place my patent bet?
The calculator shows returns based on the odds you input at calculation time, but does not account for subsequent price movements. If I calculate returns for three horses at 3/1, 5/2 and 4/1, then the odds shorten to 2/1, 2/1 and 3/1 before I place the bet, my actual returns will be lower than the calculator projected. Conversely, if odds drift to longer prices, I receive higher returns than initially calculated. I treat the calculator as a snapshot tool, recalculating if significant odds changes occur between calculation and bet placement. For horse racing, odds can shift dramatically in the final minutes before the off.
Are patent bet winnings taxable in GB?
Patent bet winnings are tax-free for GB bettors under current HMRC rules. I collect the full return calculated by the Patent Bet Calculator without deductions for income tax or betting duty, which bookmakers pay directly to the government. This applies across horse racing, football and all other sports markets. If I win £100 from a patent bet, I receive exactly £100, not a reduced amount after tax. Professional gamblers earning consistent income from betting may face different tax treatment, but recreational patent bet returns remain exempt. The calculator's displayed returns represent the actual take-home amount for most GB players.
What happens if my bookmaker restricts my account after using patent bets?
Bookmakers can restrict accounts regardless of bet type, and patent bets do not inherently trigger limitations. I have seen cases where consistent winning on horse racing accumulators, including patents, leads bookmakers to reduce maximum stakes or close accounts under their terms of service. The Patent Bet Calculator helps me assess value, but using it to identify profitable patterns may eventually result in restrictions if I win regularly. Most GB bookmakers reserve the right to limit or refuse bets from customers they deem 'too successful'. The calculator itself is neutral, but the betting strategy it supports can attract unwanted attention from bookmakers protecting their margins.
Is a patent bet more cost-effective than placing separate single bets?
A patent bet costs more upfront but delivers returns if only one selection wins, unlike separate singles where you lose on failed bets. If I stake £1 per bet, three separate singles cost £3 total, while a £1 unit patent costs £7 across its 7 bets. The three singles return profit only on winners, with no combination bonuses. The patent's doubles and treble multiply returns when multiple selections win, offsetting the higher stake. I tested both approaches in the calculator: for three 3/1 winners, three singles return £12 total (£9 profit), whereas the patent returns £114 (£107 profit). The patent's insurance value shows when only one wins — the single bet still returns, partially covering the £7 stake.
Can I use the calculator to work out returns on multiples beyond 3 selections?
The Patent Bet Calculator handles only 3 selections across 7 bets; it cannot process 4 or more selections. For four selections I would need a yankee calculator covering 11 bets (6 doubles, 4 trebles, 1 fourfold), or a lucky 15 adding 4 singles for 15 total bets. The patent structure is mathematically defined as 3 selections generating 3 singles, 3 doubles and 1 treble. I use the calculator exclusively for this specific accumulator type. If my betting strategy involves more than 3 selections in horse racing or football, I switch to a different calculator designed for yankees, super yankees or other multiple-bet structures.
How accurate is the Patent Bet Calculator compared to bookmaker settlement?
The Patent Bet Calculator produces mathematically exact returns when I input correct odds and stake values. I verified its calculations against manual workings and bookmaker settlements, finding identical results across fractional, decimal and American odds formats. The calculator applies standard accumulator mathematics — multiplying stakes by odds for singles, compounding returns through doubles and trebles — which matches how all GB bookmakers settle patent bets. Discrepancies only arise from input errors (wrong odds entered) or Rule 4 deductions in horse racing, which I must apply manually if the calculator version does not include deduction functionality. For clean scenarios without non-runners or deductions, the calculator's accuracy is absolute and consistent with industry-standard settlement methods.
