Payout by number of winners
A Lucky 15 pays out even on a single winner through its four singles. The band shows the smallest and largest return for each number of winners, since it depends on which selections win.
| Winning selections | Min profit | Max profit |
|---|---|---|
| 4 / 4 | +£101.60 | |
| 3 / 4 | +£13.40 | +£26.00 |
| 2 / 4 | £-7.60 | £-2.00 |
| 1 / 4 | £-13.20 | £-12.00 |
Min and max differ because the payout depends on which of your four picks win when the odds are not equal. Bonuses are applied to the all-win and one-winner rows above.
Lucky 15 vs Yankee
The same four selections and unit stake, as a Lucky 15 (15 bets) and a Yankee (11 bets, no singles).
| Metric | Lucky 15 | Yankee |
|---|---|---|
| Number of bets | 15 | 11 |
| Total stake | £15.00 | £11.00 |
| Return on one winner | £3.00 | £0.00 |
| Return if all four win | £116.60 | £107.30 |
A Lucky 15 costs more but returns on a single winner and often carries a bonus. A Yankee is cheaper but needs at least two winners. If you doubt more than one will land, the Lucky 15 singles earn their keep.
The Lucky 15, worked out in full
A Lucky 15 turns four selections into 15 bets, so even one winner pays and all four win big, often with a bookmaker bonus on top. As of 2026 this ToolsGambling calculator lists every one of those 15 bets, shows the return for one, two, three or four winners, folds in the bonuses, and compares the Lucky 15 to a Yankee.
Why use the ToolsGambling Lucky 15 calculator
Most Lucky 15 calculators return one figure and ignore the bonus, which is where a lot of the value actually is. This tool shows every line, every winner count and both consolation bonuses, from one tested engine, so the numbers always agree.
The bonuses, done properly
Set the all-winners percentage and the one-winner boost your bookmaker offers, and the returns update to match. Most rival calculators leave the bonus out entirely, which understates what a Lucky 15 really pays.
Every bet and every winner count
It lists all 15 lines and shows the payout band for one, two, three or four winners, so you can see the bet pay on a single result, not just the all-win total.
Lucky 15 vs Yankee, side by side
The comparison is built in and priced on your exact selections, so you can see the extra stake against the extra cover and decide with numbers.

How it differs from other Lucky 15 calculators
The bookmaker calculators that rank for this term settle a total and stop there. Few show the individual bets, the one-winner return, the each-way place line, or a configurable bonus, and none compare the Lucky 15 to a Yankee. You get a number with no working.
Everything here comes from the same round-robin engine that powers our round robin and Yankee calculators, unit-tested so the 15 lines, the scenario band, the bonuses and the comparison always add up. It is the difference between a black box and a slip you can read.
What is a Lucky 15 bet?
A Lucky 15 is a full-cover bet on four selections made up of 15 bets: four singles, six doubles, four trebles and one fourfold accumulator. The singles are what set it apart from a Yankee, because they let a single winner return.
Every combination is covered, so a Lucky 15 spreads risk widely. One winner cashes its single, two winners add the double between them, and all four land every line at once. That safety is why the Lucky 15 is a staple of horse racing accumulators.
Add a bookmaker bonus and the appeal grows: many pay a percentage if all four win and boost the odds if only one does. Scale up to five selections and it becomes a Lucky 31; six makes a Lucky 63.
I used to skip the singles and back a Yankee to save money, until a single 12/1 winner on a Lucky 15 returned more than the whole slip cost. That is the case for the singles: they turn a losing day into a small win often enough to matter.
How do you calculate a Lucky 15?
Four steps, and the tool runs them instantly. Doing it once by hand shows where the singles and the bonus fit in.
- 01
List the 15 bets
From four picks: four singles, six doubles, four trebles and one fourfold.
- 02
Multiply the odds in each line
A single is just its own odds, a double multiplies two, a treble three, the fourfold all four.
- 03
Apply your unit stake
Each of the 15 lines carries the same stake, so the total cost is 15 times your unit stake. A £1 Lucky 15 costs £15.
- 04
Add the winning lines and the bonus
Add every line whose selections won, then apply the all-winners or one-winner bonus if it triggers. The calculator does all of this at once.
Lucky 15 bonuses explained
Two consolation bonuses are common. The all-winners bonus adds a percentage, often 10%, to your total return when every selection wins. The one-winner bonus boosts the odds, usually to double or treble, when exactly one of your four wins.
The exact offer varies by bookmaker, and some apply the all-win bonus only to the win part or cap it. Set your bookmaker's terms in the calculator so the returns match your slip, and always read the small print before you stake.
Lucky 15 vs Yankee
The only structural difference is the four singles. A Lucky 15 has them, a Yankee does not, so a Lucky 15 pays on a single winner while a Yankee needs at least two. That safety costs 15 units of stake against the Yankee's 11, around 36% more.
The bonus tips the scale further toward the Lucky 15, since a Yankee rarely carries one. On four longshots the Lucky 15 usually wins; on four short-priced picks you expect to land, the cheaper Yankee can be better value. The comparison table settles it on your odds.
Lucky 15 terms
- A full-cover bet on four selections: 4 singles, 6 doubles, 4 trebles and 1 fourfold, 15 bets in total.
- The same four selections without the singles, 11 bets, so it needs at least two winners.
- A percentage added to the total return when every selection wins, commonly 10%.
- Boosted odds, usually double or treble, when exactly one of the four selections wins.
- The five-selection (31 bets) and six-selection (63 bets) versions of the same full-cover family.
- The stake on each individual line. Total cost is the unit stake times the number of bets.
