When to use the Lucky 31 bet calculator
Ideal for big meetings like Cheltenham or Aintree when you have five strong views but still want meaningful protection from singles. Use it when you want the complete stake and return across all 31 lines before you place the bet.
Lucky 31 example across five selections
A GBP 1 Lucky 31 costs GBP 31. At odds of 2.00, 2.75, 3.50, 4.00, and 6.00, one winner still returns from its single and two winners add a double. The calculator helps you see whether those singles improve realistic outcomes enough to justify the extra stake.
Lucky 31 vs Canadian
Use Lucky 31 when you want singles on a five-selection system. Use the Canadian calculator when you want the same five selections but only multiples from doubles upward.
Five-runner racing card mistakes
Lucky 31 suits racing days where bookmakers promote Lucky bets or enhanced bonuses. The common mistake is forgetting that each-way mode doubles all 31 lines. A GBP 1 each-way Lucky 31 costs GBP 62, not GBP 31.
