Lucky 15 Calculator

Work out the returns on a Lucky 15: fifteen bets across four football selections, singles included.

Use this Lucky 15 calculator to find the returns on fifteen bets across four football selections: singles, doubles, trebles and a four-fold, using decimal odds and including bookmaker bonuses where offered.

What Is a Lucky 15?

A Lucky 15 is a full cover bet across four selections that includes every conceivable combination of those four picks: four singles on each selection, six doubles combining every pair, four trebles linking three selections, and one four-fold bringing all four together. The single most attractive feature for most players is that bookmakers typically attach a bonus structure to Lucky 15 bets, offering consolation winnings even if only one selection wins, and a percentage uplift if all four come home.

The bet is popular precisely because it cushions losses and rewards partial success. A Yankee, by contrast, covers only the doubles and trebles, leaving you with nothing if fewer than two selections win. A Lucky 15 pays out on as few as one winner, though the payout on one winner will typically be small—just the winning single plus the bookmaker’s consolation bonus if they offer one.

The mathematics of a Lucky 15 is straightforward: fifteen separate bets, meaning your total outlay is fifteen times your unit stake. If you choose a unit stake of EUR 1.00, your outlay is EUR 15.00. All fifteen lines settle independently. If all four selections win, all fifteen lines pay. If only three win, the singles and combinations using those three pay out. If two win, the doubles and any combinations using just those two pay. The appeal is that you are always in profit on the full outlay if any selection wins, thanks to the consolation structure and, where available, the bookmaker bonus.

How a Lucky 15 Is Calculated

The formula for a Lucky 15 is defined by its component bets. You take four selections and create four singles—one bet on each selection individually. You then create six doubles—one for every pair of the four selections. You add four trebles, linking three selections in each combination. Finally, you include one four-fold combining all four selections into a single line. This gives you: 4 singles + 6 doubles + 4 trebles + 1 four-fold = 15 bets in total.

Your total outlay equals fifteen multiplied by your chosen unit stake. The calculator multiplies each unit stake by the relevant decimal odds to show the return for each line individually, then totals all fifteen lines to show the full payout if all four selections win.

When fewer than four selections win, the calculator determines which lines are still live—those using only the winning selections—and totals their returns. The returned profit is the gross return minus the outlay. If only one or two selections win, you will receive back less than your outlay before any bookmaker bonus is applied. Bookmaker bonuses, where offered, are applied on top of the settled returns. The bonus is controlled entirely by the bookmaker’s specific terms—this calculator shows the raw settlement mathematics only. You must check the exact bonus conditions with the operator before you place your bet, as the offer may vary.

What the Calculator Shows You

The calculator displays each of the fifteen lines as a separate bet with its own odds and decimal-odds return. It totals all fifteen returns to show the gross payout if all four selections win. It then subtracts the outlay to show your profit. It also shows the return on a partial win—for example, if three selections win but one loses, the calculator shows which lines still pay and what the combined return is. The key output fields are the total outlay, the gross return if all selections win, the profit, and the partial-win scenarios when applicable. All figures are shown in the currency of your unit stake.

Worked Example

Say you place a Lucky 15 at a unit stake of EUR 0.50 on four football selections. Your four picks are PSV to beat Sparta Rotterdam at 1.70, Olympiacos to beat Volos at 2.00, Dinamo Zagreb to beat Osijek at 2.20, and Slavia Prague to beat Jablonec at 3.00. Your total outlay is 15 bets × EUR 0.50 = EUR 7.50.

If all four selections win, each single returns the stake multiplied by the odds. The six doubles combine every pair and multiply the odds together before applying the unit stake. The four trebles combine three selections each, and the single four-fold combines all four.

The total return if all four selections win is EUR 51.34. Your profit is EUR 51.34 minus EUR 7.50 = EUR 43.84. If Slavia Prague loses but the other three selections win, your return is EUR 12.46, giving a profit of EUR 4.96. This partial return demonstrates the consolation structure: you profit even though one selection failed, from the three surviving singles, three doubles among those three selections, and one treble.

What the 15 Bets in a Lucky 15 Actually Are

The fifteen bets break down into four categories. Four are singles, each backing one selection independently. Six are doubles, covering every possible pair of your four selections. Four are trebles, covering every combination of three. The final bet is the four-fold, tying all four selections together.

Total Outlay for a Lucky 15 at Different Unit Stakes

Because a Lucky 15 always comprises exactly fifteen lines, your total outlay is always fifteen times your unit stake. The table below shows the cost at common unit stakes, allowing you to choose a stake that fits your bankroll.

The Lucky 15 Bonus and Partial Results

The Lucky 15’s distinguishing feature is the bonus structure most bookmakers attach to it: typically a consolation bonus if only one selection wins, and a percentage uplift if all four land. Those terms vary between bookmakers and are not part of the raw settlement maths, so check them—the headline return from the fifteen lines is what this calculator shows, and any bonus sits on top.

Partial results are where the Lucky 15 earns its reputation for resilience. If one of your four selections loses but three win, you still receive returns from the three surviving singles, the three doubles among those three selections, and one treble. If only two selections win, you receive returns from those two singles and the one double between them. If only one selection wins, you receive the single on that selection plus the bookmaker’s consolation bonus—often a percentage of your stake returned, though the exact terms vary. This partial-win protection is why many players regard a Lucky 15 as superior to a Yankee: the Yankee requires at least two winners to return anything on the full outlay, whereas a Lucky 15 pays on just one.

When a Lucky 15 Makes Sense

A Lucky 15 is best suited to a sequence of four selections where you have moderate confidence in each but genuine uncertainty about any of them coming home. If you are highly confident in all four picks, a simpler straight four-fold accumulator will deliver bigger returns for a fraction of the cost. If you are attempting to hedge risk and need the consolation of one or two winners paying out, a Lucky 15 is a natural fit.

The bet also makes sense when bookmaker bonuses are generous. Many bookmakers advertise Lucky 15 bonuses—often a percentage uplift on all four winning, or a fixed consolation return if just one lands. These bonuses can tip the expected value in your favour, especially if you shop between operators for the best terms. Always compare the bonus structures across bookmakers before placing your Lucky 15 bet.

A Lucky 15 requires sufficient bankroll discipline: at EUR 2.00 per line, the outlay reaches EUR 30.00, and if your selections are poor, losing that sum becomes more painful. It is important to view the unit stake as the core cost of the bet and to ensure your bankroll can comfortably absorb the full outlay. If you are confident in two selections out of four but uncertain about the others, a round robin or a smaller system might suit better. If you favour one or two standout picks and want to build around them with additional coverage, a single or double may serve you better than committing to four selections.

Common Mistakes

Assuming the bonus is automatic—the terms differ between bookmakers. Forgetting the outlay is fifteen times the unit stake. Expecting one winner to produce a profit rather than just a partial return. Comparing a Lucky 15’s return with a Yankee’s without allowing for the extra outlay.

Lucky 15 in the Lucky Family and Against a Yankee

The Lucky family scales the concept: a Yankee uses four selections but only eleven lines, whilst a Lucky 15 adds four singles for a total of fifteen. A Lucky 31 extends to five selections across thirty-one lines, and a Lucky 63 to six selections across sixty-three lines.
