Enter your stake per line, add 5 odds (decimal like 3.50 or fractional like 5/2), then tick the winners. This calculator returns total stake, estimated return, and profit/loss for a standard Lucky 31 win bet.
What is a Lucky 31 bet?
A Lucky 31 is a multiple bet made from 5 selections. It contains 31 total lines:
- 5 singles
- 10 doubles
- 10 trebles
- 5 four-folds
- 1 five-fold
Because singles are included, you can still get a return even if only one selection wins. That makes Lucky 31 a popular choice for football accumulators, horse racing cards, and weekend multi-event slips.
How this Lucky 31 calculator works
This tool calculates returns using your stake per line. Since a Lucky 31 has 31 lines, your total stake is:
Total stake = stake per line × 31
Each winning line is paid using decimal odds (including stake). If you enter fractional odds (like 5/2), the calculator converts them automatically to decimal odds before calculating.
Example
If your stake per line is £1, your total stake is £31. If two selections win, all winning singles and doubles among those winners are paid; all other lines lose.
Why outcomes vary so much
Lucky 31 returns are highly sensitive to:
- Number of winners (1, 2, 3, 4, or 5)
- Odds profile (short odds vs bigger prices)
- Stake per line
- Bookmaker bonuses for 4 or 5 winners (if offered)
Two slips with the same number of winners can produce very different payouts if one set has higher odds.
Lucky 31 vs accumulator
Accumulator (5-fold only)
- Cheaper stake
- Needs all 5 to win for return
Lucky 31
- Much higher total stake
- Can return with just 1 winner
- Bigger upside if many selections win
Good staking habits
Because Lucky 31 creates 31 lines, costs can rise quickly. Consider:
- Setting a fixed unit stake (for example £0.50 or £1 per line)
- Avoiding random odds chasing
- Tracking results over time
- Using clear bankroll limits
Responsible gambling reminder
Betting should be entertainment, not income. Never stake money you cannot afford to lose. If gambling stops being fun, seek support in your country’s responsible gambling services.
