Lucky 15 Calculator
15 bets on 4 selections — singles included, plus bookmaker bonuses.
A Lucky 15 is 15 bets from 4 selections (4 singles, 6 doubles, 4 trebles, 1 four-folds). Void/non-runner legs settle at 1.00, shrinking any line they're in. Each-way doubles the stake and pays a place accumulator at each leg's terms.
How a Lucky 15 works
A Lucky 15 is fifteen bets on four selections: four singles, six doubles, four trebles and the four-fold. It's a Yankee with the singles added back, so a single winner already returns something — and most bookmakers sweeten it with bonuses. The two common ones, both editable above: the odds on your only winner are boosted if just one comes in, and a percentage is added if all four win.
Worked example, one winner: a £1 Lucky 15 costs £15. If only your 4/1 shot wins and the book doubles the odds on a lone winner, that single pays as an 8/1 winner — £9 back, softening the £15 outlay to a £6 loss. Worked example, all four: four winners at 2/1 each return £255 before the bonus; a 10% all-winners bonus lifts that to £280.50.

FAQ
Which bonuses should I set?
They vary by bookmaker — some double a lone winner's odds, some treble; the all-winners bonus is often around 10%. The fields default to 0, so enter your bookmaker's terms to fold the bonus into the total.
Does the one-winner bonus stack with the all-winners one?
No — one applies when exactly one selection wins, the other when all four do, so only one is ever in play.
Lucky 15 or Yankee?
The Lucky 15 adds the singles and bonuses for four extra units of stake; the Yankee is the leaner 11-bet version. Stepping up a selection gives the Lucky 31.
Each-way Lucky 15s are a horse-racing staple — tick each-way, set each leg's place terms, and the stake doubles. Feed it the best price on every selection; on fifteen bets the compounding margin cuts deep if you don't.
