Lucky 15 Bet Calculator

If you've put four selections into a Lucky 15, checking the result means working through more than one bet. There are singles to settle alongside the doubles, trebles and four-fold. Our Lucky 15 bet calculator brings those calculations together, whether you're looking at a possible outcome from our online sports betting markets or checking a bet that's already finished.

For an existing bet, keep the accepted slip beside you. The odds on it are the ones to enter, even if a different price is now showing for the same selection. That difference is easy to miss when you've gone back to a racecard or fixture to check a result.

Start by matching the odds format to the figures you're using. With fractions selected, you need the fractional price in each row; switch to decimals if that's how the prices appear on your slip. The selection notes can help here too. Adding a horse's name or a reminder of the match means you won't have to remember which of the four rows it belongs to.

You'll see Winner beside each selection to begin with. Leave those entries as they are when you're exploring an all-winners result. For a bet that has settled, go through them individually and change any that didn't win. It only takes one incorrect outcome to produce a breakdown that doesn't match the actual bet.

There's another detail to check before calculating: what the stake field represents. A figure entered per bet is applied across all 15 lines. A total stake is the amount for the whole Lucky 15, shared between them. Read the selected option before entering your figure, particularly if you've just been using a calculator for a single bet.

Suppose two of your four selections win and the other two lose. On a standard win-only Lucky 15, without voids or dead heats, you have two winning singles and a winning double formed from that pair. The lines involving either losing selection have lost. Three winners would leave three successful singles, three doubles and a treble.

Those singles are the extra bets you have in a Lucky 15 compared with a Yankee. With just one winner, its single still settles successfully, although that return can fall short of what you staked across the whole bet. All four losing means the entire win-only stake has gone. Putting combinations into a calculator won't make any outcome more likely.

An each-way slip needs another set of calculations for the place side. You have the same 15 combinations on that side as on the win side, making 30 lines altogether. At an unchanged stake per line, you've doubled the total cost. Enter the place fraction from your bet, rather than leaving it to memory.

For a horse that finished third, look back at how many places its race paid. Third could qualify in one race and fall outside the terms in another. That's why the terms on each selection matter when you enter the results.

A withdrawn horse needs a check against its settled status too. It may be recorded as void on your bet, which isn't the same as losing. For any applicable Rule 4 deduction or dead heat, use the relevant settings where available to account for the settlement adjustment.

The figures are now ready to compare with your bet record. You can try other outcomes in the calculator, but you're changing only those figures. An accepted bet keeps its original details and is settled under the rules that apply to it.
