Patent Calculator
A Trixie plus singles — seven bets, and one winner still returns something.
A Patent covers three selections in seven bets: three singles, three doubles and a treble. The singles are the point — they are what turns a single winner from a total loss into a partial return.

The same £7.00 on a single 3-fold accumulator would return £56.00 if everything won, against £26.00 here. The difference is what you are paying for the softer landing — and each line carries its own compounded margin, so this is a way to spread risk, not an edge.
Common questions
- How much does a Patent cost?
- A Patent is 7 separate bets, so your total stake is 7 times your stake per line. A £1 Patent costs £7, not £1 — the single most common surprise with these bets, and the reason the calculator shows total stake before anything else.
- How many bets is a Patent?
- 7. It covers doubles, trebles, plus a single on each selection across 3 selections. That count is fixed by the maths — it is every combination of those sizes — which is why every bookmaker's Patent has exactly 7 lines.
- How many winners do I need for a Patent to pay out?
- To get anything back, one winner already returns something. To actually profit is a different question and depends entirely on your prices — at short odds you can win most of your selections and still lose money, because the losing lines outnumber the winning ones. The scenario table shows the exact point where your ticket turns a profit.
- Is a Patent worth the extra stake over a Trixie?
- It depends entirely on your prices. The 3 extra singles raise your outlay by 75% (4 bets to 7) and in exchange guarantee a return whenever any selection wins. At short odds that return will not cover the extra stake; at longer odds it can. Run both in the calculator with your actual prices rather than taking a rule of thumb.
