This Lucky 15 calculator works out your returns on a Lucky 15, Lucky 31 or Lucky 63 before you place the bet. Enter the odds for each selection, set a result for each one and see your total stake, return and profit. You can also switch to a Yankee, Canadian or Heinz.
- A Lucky 15 is 15 bets on 4 selections: 4 singles, 6 doubles, 4 trebles and 1 fourfold.
- A Lucky 31 is 31 bets on 5 selections and a Lucky 63 is 63 bets on 6 selections.
- The stake is per bet. A €1 Lucky 15 costs €15, and an each-way Lucky 15 has 30 bets.
Change the bet type to see the Lucky 31 and Lucky 63, then set a result against each selection to see what your slip pays.
What is a Lucky 15?
A Lucky 15 is a full-cover bet on four selections in different events. It places 15 separate bets covering every possible combination: four singles, six doubles, four trebles and one fourfold accumulator. Because the singles are included, you are paid something if only one of your four selections wins, which you would not get from a plain accumulator.
Lucky 15, Lucky 31 and Lucky 63 compared
| Bet | Selections | Singles | Doubles | Trebles | Fourfolds | Fivefolds | Sixfold | Total bets |
|---|---|---|---|---|---|---|---|---|
| Lucky 15 | 4 | 4 | 6 | 4 | 1 | – | – | 15 |
| Lucky 31 | 5 | 5 | 10 | 10 | 5 | 1 | – | 31 |
| Lucky 63 | 6 | 6 | 15 | 20 | 15 | 6 | 1 | 63 |
Each step up adds one selection, which roughly doubles the number of bets. More selections means more cover but also a bigger total stake, and a bet only returns if every selection in that particular combination wins.
How to use the Lucky 15 calculator: worked example
Put €1 on each bet in a Lucky 15, so your total stake is €15, with selections at evens, 2/1, 3/1 and 4/1 (decimal 2.0, 3.0, 4.0 and 5.0).
- All four win: singles €14 + doubles €71 + trebles €154 + fourfold €120 = €359. Profit is €344.
- One winner (the 4/1 selection): only that single pays, returning €5. A loss of €10.
- Two winners (2/1 and 3/1): €3 + €4 from the singles and €12 from the double = €19. A profit of €4.
- No winners: you lose the €15 stake.
Notice that one winner at 4/1 does not cover the stake. A full-cover bet needs a winner at fairly long odds, or more than one winner, to come out ahead.
Worked example: Lucky 31 and Lucky 63
To keep the sums clear, imagine every selection is at evens (decimal 2.0) and you stake €1 per bet. If all of them win, the return is a total of 3 to the power of the number of selections, minus 1.
- Lucky 31 with five evens winners: total return €242 on a €31 stake.
- Lucky 63 with six evens winners: total return €728 on a €63 stake.
- Only one evens winner: in either bet you are paid €2 from the single, well under your total stake.
How is a Lucky 15 different from a Yankee?
A Yankee covers the same four selections but starts at doubles, so it has 11 bets and no singles. It costs less per unit stake, but you need at least two winners to be paid. A Lucky 15 adds the four singles, which is why it costs 15 units but pays out on a single winner. The same relationship holds for the Lucky 31 against the Canadian and the Lucky 63 against the Heinz. For three selections, compare the Trixie calculator with the Patent calculator, and for five selections use the Lucky 31 calculator. If you only want a straight accumulator, try the accumulator calculator.
Lucky 15 bonuses and what this calculator leaves out
Many bookmakers advertise bonuses for Lucky 15 and similar bets, for example extra winnings if all selections win, or a boost if only one does. These vary by bookmaker and by offer, so this calculator does not include them. Check the terms on your slip before you rely on a bonus.
- Rule 4 deductions and dead heats are not applied
- A void selection is treated as odds of 1.00, which is how most bookmakers settle it
- Each-way Lucky 15s double the number of bets to 30, with a win and place part for every combination
For other bet types use the main bet calculator, and see our guide to bet types explained for when each one makes sense. The each way calculator covers place terms in more detail, and the free bet calculator and odds converter cover the rest of your slip.
How many winners do you need in a Lucky 15?
Because a Lucky 15 costs 15 units, you need more than one winner to cover your stake unless the winner is at long odds. Here is a €1 Lucky 15 where all four selections are at evens (2.0 in decimal), so the total stake is €15:
| Winners | Total return | Profit or loss |
|---|---|---|
| 0 | €0 | -€15 |
| 1 | €2 | -€13 |
| 2 | €8 | -€7 |
| 3 | €26 | +€11 |
| 4 | €80 | +€65 |
At evens you need three winners to be in profit. At longer odds a single winner can cover more of the stake, which is why Lucky 15s are usually played on selections priced at 2/1 or more. The return for each case comes from the single, double, treble and fourfold bets that include only your winners, as in the worked example above.
Each-way Lucky 15
An each-way Lucky 15 splits every bet into a win part and a place part, which makes 30 bets. At €1 per bet that is a €30 total stake. The place bets pay when selections finish in the places, so you can be paid something even when no selection wins. The cost is double, and terms vary by race, so check the place terms on each selection. Our each way calculator covers the sums for each-way multiples.
Lucky 15 compared with singles and an accumulator
You could instead place four separate singles, which costs less to cover, or a fourfold accumulator, which pays much more if all four win. A Lucky 15 sits in between: it pays on a single winner, but you pay for the 11 multiples that need two or more winners. For more on how the bet types compare, see bet types explained.
Frequently asked questions
How many bets are in a Lucky 15?
There are 15 bets: 4 singles, 6 doubles, 4 trebles and 1 fourfold accumulator.
How much does a Lucky 15 cost?
The stake per bet multiplied by 15. At €1 per bet it costs €15, at €2 it costs €30 and at €5 it costs €75. An each-way Lucky 15 has 30 bets, so it costs twice as much.
What do I get if only one selection wins in a Lucky 15?
You are paid on the single for that selection only. At 4/1 and €1 per bet you receive €5, which is less than the €15 total stake. At longer odds one winner can cover the stake.
Do all four selections have to win in a Lucky 15?
No. That is the point of the bet. Each of the 15 bets is settled separately, so you can be paid when only some selections win.
How many bets are in a Lucky 31 and a Lucky 63?
A Lucky 31 has 31 bets on five selections. A Lucky 63 has 63 bets on six selections.
Is a Lucky 15 better than an accumulator?
It is different. A fourfold accumulator costs one unit and needs all four to win. A Lucky 15 costs 15 units but pays on one, two or three winners as well. Which suits you depends on how confident you are in the selections and how much you want to risk.
Does the calculator include Lucky 15 bonuses?
No. Bonuses for winning Lucky 15s differ by bookmaker and offer, so check the terms on your bet slip.
Is a Lucky 15 worth it?
A Lucky 15 pays out when only one or two selections win, but it costs 15 units, so you usually need at least two winners, or one at long odds, to cover the stake. At evens you need three winners to profit. Whether it suits you depends on the odds and how much cover you want.
Can I place an each-way Lucky 15?
Yes, many bookmakers offer an each-way Lucky 15, which has 30 bets: 15 win bets and 15 place bets. The total stake is double the win-only version.
What is the difference between a Lucky 15, a Trixie and a Patent?
A Trixie has four bets on three selections and no singles. A Patent covers the same three selections with seven bets, including the singles. A Lucky 15 covers four selections with 15 bets, including the singles.
