Lucky 15 calculator

What a Lucky 15 is

A Lucky 15 combines four selections into every single, double, treble and four-fold. That makes 15 separate bets, and each one is staked on its own.

One winner, and still down

A £1-per-line Lucky 15 costs £15. If only one selection wins, at decimal odds of 5.00, the base return is £5 and you are £10 down.

The four singles are why a single winner always returns something. That return may not cover the total stake, though, because the doubles, trebles and four-fold all contain a loser and pay nothing. The calculator opens on exactly this case, so you can change a result and watch the lines switch on.

Each way means 30 lines

Tick each way and the bet doubles: a win line and a place line for every combination. A £1-per-line each-way Lucky 15 costs £30, not £15.

The place part settles at the win odds reduced by the place fraction, applied to the profit rather than the whole price. At 5.0 with 1/4 terms, that is 1 + (5 − 1) ÷ 4 = 2.0. Pick the place terms from your slip, because they change with the race. The each-way calculator covers a single each-way bet in more detail.

Lucky 15, Yankee and Lucky 31

A Yankee also uses four selections but leaves out the singles, so it has 11 lines. A Lucky 31 keeps the singles and adds a fifth selection, which makes 31 lines. The singles are what separate a Lucky 15 from a Yankee.

How this calculator settles

• Odds can be typed as decimals (5.0), fractions (4/1) or evens.
• A line returns its stake times the odds of every selection in it, and nothing if any selection in it lost.
• A void selection is settled at odds of 1.0. Your bookmaker's rules decide the real settlement.
• Bookmaker bonuses and refunds are not included. They differ between bookmakers.
• Each line is shown to the penny. The total is rounded once from the unrounded lines, so the lines can differ from it by a penny or two.

Questions

How many bets are in a Lucky 15?

There are 15 bets: four singles, six doubles, four trebles and one four-fold accumulator.

How much does a £1 Lucky 15 cost?

A £1-per-line win-only Lucky 15 costs £15, because it has 15 lines. A £1-per-line each-way Lucky 15 has 30 lines, so it costs £30.

Do all four selections need to win?

No. The four singles mean one winner can return money, but that one return may still be less than the total stake. Each extra selection that wins switches on more doubles, trebles and the four-fold.

What is the difference between a Lucky 15 and a Yankee?

Both use four selections. A Lucky 15 includes the four singles, which makes 15 lines. A Yankee leaves the singles out and has 11 lines.

How is an each-way Lucky 15 settled?

Each way doubles the lines from 15 to 30: a win line and a place line for every combination. The place part settles at the win odds reduced by the place fraction, applied to the profit. At 5.0 with 1/4 terms, the place part settles at 1 + (5 − 1) ÷ 4 = 2.0.

Does this calculator include bookmaker bonuses?

No. It settles the base bet only. Bonuses and refunds are set by each bookmaker, so check the terms on your slip.
