Lucky 15 calculator

A Lucky 15 is 15 bets across 4 selections — 4 singles plus a full Yankee (6 doubles, 4 trebles, 1 fourfold). Even one winner pays out, and most bookmakers add bonuses.

How a Lucky 15 works

Structure: 4 selections → 4 singles + 6 doubles + 4 trebles + 1 fourfold = 15 bets. Total stake is your unit stake × 15 (× 2 if each-way).

Because it includes singles, a single winner returns money. The two common bonuses are a one-winner bonus (your lone winning single paid at double or treble the odds) and an all-winners bonus (a percentage added to total returns when all four win). Toggle both above to match your bookmaker — terms vary, so check theirs.

This is a returns calculator, not a prediction. It shows what a Lucky 15 would pay for the odds and results you enter — it does not forecast outcomes and we do not sell tips. A winning line's return is your unit stake × the combined decimal odds of that line.
