What Is a Lucky 15 Bet?

A Lucky 15 is a popular accumulator-style bet made from four selections. It contains 15 total bets:

• 4 singles
• 6 doubles
• 4 trebles
• 1 fourfold accumulator

Because you are covering multiple combinations, you can still get a return even if only one or two selections win. That flexibility is why many bettors like Lucky 15s, especially compared with a single all-or-nothing accumulator.

How This Lucky 15 Calculator Free Tool Works

1) Enter stake per line

Your stake is applied to each of the 15 lines. If your stake per line is 1.00, your total outlay is 15.00.

2) Enter the four odds

You can use decimal odds (for example, 6.00) or fractional odds (for example, 5/1). Fractional inputs are automatically converted to decimal format behind the scenes.

3) Mark winners and calculate

Select which picks won, then click the button. The calculator instantly shows:

• Lines won by type (singles, doubles, trebles, fourfold)
• Total return
• Total stake
• Profit or loss
• Potential return if all four selections had won

Lucky 15 Return Formula (Simple Version)

For each winning line:

Return = Stake per line × Product of decimal odds in that line

For example, a double with decimal odds 2.50 and 3.00 at 1.00 stake returns:

1.00 × 2.50 × 3.00 = 7.50

The total Lucky 15 return is the sum of all winning line returns.

Example: All Four Selections Win

Suppose your odds are 2.50, 3.00, 4.00, and 5.00 with 1.00 stake per line:

• Singles return: 14.50
• Doubles return: 77.00
• Trebles return: 177.50
• Fourfold return: 150.00
• Total return: 419.00
• Total stake: 15.00
• Profit: 404.00

Some bookmakers pay bonuses for all winners, but this calculator keeps things clean by showing the core mathematical return first.
