How a full-cover bet calculator works
If the bet names are new to you, our guide to the types of bets explains them first. A full-cover bet turns a handful of selections into many smaller bets at once. Instead of one accumulator that needs every selection to win, a Trixie, a Yankee or a Lucky 15 covers every combination of a set size. Three horses give four bets in a Trixie, four give eleven in a Yankee and fifteen in a Lucky 15. The stake you enter is the amount on each bet, not the total, so the total stake is that amount times the number of bets.
Each bet is worked out on its own. A single returns your stake times the decimal odds if the selection wins. A double returns the stake times both prices multiplied together, and a treble times three. If one selection in a combination loses, that whole bet loses and the others carry on. The calculator adds the returns of every bet that is still alive and subtracts the total stake to give the profit or loss.
Choose the bet, set the stake, enter the odds as a fraction like 5/2, as evens or as a decimal like 3.5, and set each selection to Won, Lost or Non-runner. The table under the figures shows the same bet in three outcomes: every selection wins, only the first wins, and none wins. For a Lucky 15 at £1 per bet the middle line is the one to look at, because it shows how a single winner can still return less than the total stake.
Lucky 15 calculator: fifteen bets from four selections
A Lucky 15 is four singles, six doubles, four trebles and one four-fold. That is fifteen bets, so £1 per bet costs £15. Its appeal is that one winner still returns something, because the singles are in the bet. The cost is that the singles and the small combinations carry most of the stake, so the bet needs a winner at a good price to cover it.
| Outcome | Total stake | Return | Profit or loss |
|---|---|---|---|
| All four win | £15.00 | £539.00 | £524.00 |
| The first two win | £15.00 | £17.00 | £2.00 |
| Only the first wins | £15.00 | £3.00 | -£12.00 |
| None wins | £15.00 | £0.00 | -£15.00 |
Read the table across. With all four winners the four-fold and the trebles do the work. With two winners, the two singles and the one double that joins them are all that is left, and with one winner at 2/1 the return is £3 against a stake of £15. A Lucky 15 is a way of spreading risk across combinations, and a way of spending fifteen units, not a way of making a loss unlikely.
Trixie calculator: four bets from three selections
A Trixie is three doubles and one treble on three selections, four bets in all. It has no singles, so at least two selections must win for any return. That makes it cheaper per selection than a Lucky 15, and it makes the outcomes sharper: one winner returns nothing at all.
| Outcome | Total stake | Return | Profit or loss |
|---|---|---|---|
| All three win | £40.00 | £1070.00 | £1030.00 |
| The first two win | £40.00 | £120.00 | £80.00 |
| Only the first wins | £40.00 | £0.00 | -£40.00 |
| None wins | £40.00 | £0.00 | -£40.00 |
A Trixie suits three selections you fancy about equally and where a single winner is not enough for you. If you want a return from one winner, the Patent below adds the three singles.
Patent bet calculator: seven bets from three selections
A Patent is the Trixie with three singles added: three singles, three doubles and one treble, seven bets. It costs more than a Trixie at the same stake per bet, and it pays something if any one selection wins. The calculator offers it as its own bet type.
| Outcome | Total stake | Return | Profit or loss |
|---|---|---|---|
| All three win | £14.00 | £238.00 | £224.00 |
| The first two win | £14.00 | £38.00 | £24.00 |
| Only the first wins | £14.00 | £6.00 | -£8.00 |
| None wins | £14.00 | £0.00 | -£14.00 |
Yankee, Canadian, Heinz and the bigger bets
The pattern repeats as selections are added. A Yankee is four selections in eleven bets, a Canadian or Super Yankee is five selections in twenty-six, a Heinz is six in fifty-seven, a Super Heinz is seven in a hundred and twenty and a Goliath is eight in two hundred and forty-seven. None of them has singles. Each has a Lucky version that adds the singles: a Lucky 31 on five selections, a Lucky 63 on six.
| Bet (selections) | Singles | Doubles | Trebles | Four-folds and up |
|---|---|---|---|---|
| Trixie (3) | 0 | 3 | 1 | 0 |
| Patent (3) | 3 | 3 | 1 | 0 |
| Yankee (4) | 0 | 6 | 4 | 1 |
| Lucky 15 (4) | 4 | 6 | 4 | 1 |
| Canadian (5) | 0 | 10 | 10 | 6 |
| Lucky 31 (5) | 5 | 10 | 10 | 6 |
| Heinz (6) | 0 | 15 | 20 | 22 |
| Lucky 63 (6) | 6 | 15 | 20 | 22 |
| Super Heinz (7) | 0 | 21 | 35 | 64 |
| Goliath (8) | 0 | 28 | 56 | 163 |
| Bet | Bets | £1 per bet | £2 per bet | £5 per bet |
|---|---|---|---|---|
| Trixie | 4 | £4.00 | £8.00 | £20.00 |
| Patent | 7 | £7.00 | £14.00 | £35.00 |
| Yankee | 11 | £11.00 | £22.00 | £55.00 |
| Lucky 15 | 15 | £15.00 | £30.00 | £75.00 |
| Canadian | 26 | £26.00 | £52.00 | £130.00 |
| Lucky 31 | 31 | £31.00 | £62.00 | £155.00 |
| Heinz | 57 | £57.00 | £114.00 | £285.00 |
| Lucky 63 | 63 | £63.00 | £126.00 | £315.00 |
| Super Heinz | 120 | £120.00 | £240.00 | £600.00 |
| Goliath | 247 | £247.00 | £494.00 | £1235.00 |
The number of bets grows quickly, and so does the cost of a given stake per bet. A Goliath at £1 per bet is £247, which is why the stake field asks for the amount per bet. Check the total before you place a bet like that.
Where the number of bets comes from
The count is a matter of choosing groups. The number of doubles on five selections is the number of ways to pick two from five, which is ten. The number of trebles is the number of ways to pick three from five, also ten. Add the five four-folds and the single five-fold and the Canadian comes to ten, ten, five and one, twenty-six bets with no singles. A Lucky 31 adds the five singles for thirty-one.
The same sum explains why a sixth selection changes the cost so much. Six selections give fifteen doubles, twenty trebles, fifteen four-folds, six five-folds and one six-fold, fifty-seven bets in a Heinz. Each added selection roughly doubles the number of bets, so decide how many selections you really want before you choose the bet.
Win only or each way
Bookmakers take most full-cover bets either way. Every bet above can be placed win only or each way. Win only is the default here. Each way doubles the number of bets, because every line gets a win part and a place part, and the place part is paid at a fraction of the odds if the selection finishes in the places. Switch the calculator to Each way and it asks for the place terms, such as one quarter or one fifth.
| Outcome | Win only: stake | Win only: return | Each way: stake | Each way: return |
|---|---|---|---|---|
| All four win | £15.00 | £539.00 | £30.00 | £592.14 |
| First wins, other three lose | £15.00 | £3.00 | £30.00 | £4.50 |
| First wins, other three place only | £15.00 | £3.00 | £30.00 | £56.14 |
A Lucky 15 at £1 per bet costs £15 win only and £30 each way. The extra £15 buys the chance of a place return on horses that do not win, and it pays off only when the place terms and the prices make it worth the extra stake. Our each way calculator goes into places, fractions and dead heats in detail.
Non-runners, void bets and Rule 4
When a selection is a non-runner, its bets are not lost. The selection is taken out, and every bet that contained it continues on the remaining selections at their prices. A Yankee with one non-runner pays like a Trixie on the other three, with its doubles and its treble counted twice, because each of them now appears once with the non-runner and once without it.
| Bet | Total stake | Return if the other three win |
|---|---|---|
| Yankee, all four selections win | £11.00 | £821.00 |
| Yankee, first selection a non-runner | £11.00 | £403.00 |
| Trixie on the other three, for comparison | £4.00 | £194.00 |
Set a selection to Non-runner to see it. Rule 4 is a different matter. When a horse is withdrawn after you have bet on a race, a deduction from the winnings of the bets on the other horses can apply, and the calculator lets you choose the deduction for each selection. The Rule 4 explainer shows how the deduction scale works step by step, and the horse racing betting sites guide says where the terms sit.
The stake on the lines that contained the non-runner is not lost, and it is not refunded as a separate payment: those lines simply become smaller bets that are still running. The total stake you placed stays the same, which is why the return in the table can be higher than the return of a plain Trixie for the same three winners.
Choosing between an accumulator and a full-cover bet
An accumulator is one bet. If every selection wins the return can be large, and if one loses everything is lost. A full-cover bet gives up some of that return to keep some bets alive when a selection loses. Neither is better in itself. The odds you can take on each selection and the amount you are happy to spend decide it. The accumulator calculator works out a plain accumulator, the dutching calculator splits one amount across selections so each pays the same, and the odds converter reads a price in any format and shows the chance it implies.
It is worth remembering that every price includes the bookmaker’s margin. Joining several prices multiplies the margin as well, and the chance that every leg wins together is smaller than any single leg. The more selections, the lower the chance of the biggest return.
Bookmaker offers on Lucky 15s and other full-cover bets
Bookmakers advertise extra payouts on some full-cover bets, such as a bonus if all selections win or an extra if only one does. We do not print the figures, because they change and they come with conditions on the minimum odds, the number of selections and the markets that count. The calculator uses the plain prices you enter and does not add any bonus. If you place a bet with an offer, read the terms of the offer on the bookmaker’s own page and add its effect separately.

Common mistakes with full-cover bets
The first is reading the stake as the total. £5 on a Lucky 15 is £75, not £5. The second is expecting one winner to cover the bet. With four selections it only does if the winner is at a long price, and the table above shows the cost of a short one. The third is changing selections after the stake is set without recounting the bets. The fourth is forgetting that a lost selection takes down every bet it is in, so a bet with many combinations can lose almost everything with one wrong selection.
Responsible betting with full-cover bets
Full-cover bets can turn a small stake per bet into a large total. Work out the total before you place it, and set a deposit limit in your account before you start. Betting is for people aged 18 and over. If gambling stops being fun, Free, confidential help is available from GambleAware, and GamStop lets you block every licensed UK site in one step.

How the calculator works
Each bet is worked out line by line. A Lucky 15 has fifteen lines: four singles, six doubles, four trebles and one four-fold. For every line the return is the stake times the product of the decimal prices of its selections, and the line pays only if every selection in it won. A non-runner or void selection counts as a price of 1, so its lines continue on the remaining selections. A Rule 4 deduction reduces the profit part of a price before the multiplication. In each way mode every line also carries a place part at the chosen fraction of the odds. The same function produces the figures in the calculator and the tables on this page, and it is checked by automated tests against hand-worked examples. It is arithmetic, not a forecast, and the bookmaker’s own terms decide how a real bet is settled.
Questions about the bet calculator
What is a full-cover bet?
A bet that covers every combination of a set size across your selections, such as a Trixie on three selections or a Lucky 15 on four. Several bets are placed at once, and a losing selection only ends the bets it is in.
How many bets are in a Lucky 15, a Yankee and a Trixie?
A Lucky 15 has 15, a Yankee 11 and a Trixie 4. A Patent has 7, a Canadian 26, a Lucky 31 has 31, a Heinz 57, a Lucky 63 has 63, a Super Heinz 120 and a Goliath 247.
What is the difference between a Lucky 15 and a Yankee?
Both use four selections. A Lucky 15 adds four singles to the eleven bets of a Yankee, so one winner can still return something.
What is the difference between a Trixie and a Patent?
A Patent is a Trixie with three singles added: seven bets instead of four. A Trixie needs two winners to return anything.
Is the stake the total or the amount on each bet?
The amount on each bet. A £2 stake on a Yankee is £22 in total, and doubles to £44 if the bet is placed each way.
What happens to a full-cover bet if a selection is a non-runner?
The selection is taken out and the bets that included it carry on with the remaining selections at their prices.
What is a Super Yankee?
Another name for a Canadian: five selections in twenty-six bets.
Can I use the calculator for each way bets?
Yes. Switch the bet to Each way, choose the place terms, and every bet gets a place part as well as a win part. The total stake doubles.
Does the calculator include bookmaker bonuses on Lucky 15s?
No. It uses the plain prices you enter. Offers vary and carry conditions, so read the terms of any offer and add its effect separately.
Does the calculator place a bet?
No. It works out stakes and returns from the numbers you type. It does not place bets and it is not a forecast.
