Lucky 15 Calculator
A Lucky 15 turns four selections into fifteen separate bets, which makes working out your returns by hand slow and easy to get wrong — especially once a non-runner or a bookmaker bonus is involved.
Enter your four prices below, mark each selection as won, lost or void, and this calculator settles all fifteen lines for you.
Quick Answer
A Lucky 15 is four selections combined into 15 bets: 4 singles, 6 doubles, 4 trebles and 1 fourfold. A £1 Lucky 15 therefore costs £15. One winner alone still returns something, because every selection is covered by its own single.

Bonus terms differ between bookmakers and change over time — set the one-winner and all-winners fields to match your own bookmaker's current rules before relying on the figures.
What makes up the 15 bets
The four singles cover each selection on its own. The six doubles pair every possible combination of two. The four trebles cover every group of three, and the fourfold needs all four to land.
Because the singles are included, a Lucky 15 pays out on one winner where a straight fourfold accumulator would return nothing. That safety net is what you are buying with the extra stake.
How the bonuses work
Two bonuses are common. The one-winner consolation applies when exactly one of the four selections wins, typically doubling the odds on that single. The all-winners bonus adds a percentage to your total returns when every selection lands.
These terms are not standard across the industry and they change. The calculator leaves both under your control so you can match whatever your bookmaker currently offers rather than trusting a hardcoded assumption.
Non-runners and void selections
A void selection does not kill the bet. Each line containing it simply settles at the remaining odds, so a double becomes a single and a treble becomes a double. Set the selection to Void and every affected line is recalculated.
This is the part people most often get wrong by hand, because fourteen of the fifteen lines can change at once.
Lucky 15 on football
The bet came from horse racing but the maths does not care what you are betting on. Four football selections work exactly the same way, whether that is match results, both teams to score, or goals lines.

Frequently Asked Questions
How many bets are in a Lucky 15?▼
Fifteen. A Lucky 15 takes four selections and combines them into 4 singles, 6 doubles, 4 trebles and 1 fourfold accumulator. Because every line carries the same stake, a £1 Lucky 15 costs £15 in total, or £30 each way.
Do you need all four selections to win?▼
No, and that is the point of the bet. One winner already returns something because each selection is covered by its own single. Two winners add a double, three winners add three doubles and a treble. You need all four only for the fourfold and any all-winners bonus.
What is the one-winner bonus?▼
Many bookmakers pay extra when exactly one of your four selections wins, usually by doubling the odds on that single, and sometimes trebling them. Terms vary between bookmakers and change over time, so set the bonus fields in the calculator to match your own bookmaker rather than assuming a default.
What happens if a selection is a non-runner?▼
A void selection does not lose the bet — it shrinks it. Every line containing that selection settles at the remaining odds, so a double becomes a single and a treble becomes a double. Set that selection to Void in the calculator and the fifteen lines are recalculated accordingly.
Is a Lucky 15 worth it compared to four singles?▼
It depends on how many of your selections land. Four singles are cheaper and pay more when only one wins. A Lucky 15 costs nearly four times as much but pays far more when three or four win, because the doubles, trebles and fourfold all come in on top. It is a bet that rewards being right repeatedly, not occasionally.
Can you place a Lucky 15 on football?▼
Yes. The bet started in horse racing but works with any four selections, including football match results, both teams to score, or over and under goals lines. The maths is identical — only the markets change.
