Horse Racing Calculator
Calculate your superfecta box ticket cost by entering a base bet and the number of horses in the box. A superfecta box covers every four-horse finishing order among your selected runners. Combinations follow n × (n − 1) × (n − 2) × (n − 3), and cost rises steeply with each added horse.
Enter your base bet per combination and the number of horses in the box. The calculator applies n × (n − 1) × (n − 2) × (n − 3) to find total combinations, then multiplies by your base bet.
Enter a base bet and horse count, then press Calculate to see ticket combinations and estimated cost.
Formula: combinations = n × (n − 1) × (n − 2) × (n − 3). All values below are pre-verified against the permutation formula.
| Horses in box | Combinations | $0.10 base | $0.50 base | $1 base |
|---|---|---|---|---|
| 4 | 24 | $2.40 | $12.00 | $24.00 |
| 5 | 120 | $12.00 | $60.00 | $120.00 |
| 6 | 360 | $36.00 | $180.00 | $360.00 |
| 7 | 840 | $84.00 | $420.00 | $840.00 |
| 8 | 1,680 | $168.00 | $840.00 | $1,680.00 |
A 5-horse superfecta box at $0.10 base costs $12. A 6-horse box at $0.10 costs $36. A 7-horse box at $0.10 costs $84. Adding horses multiplies through four position terms.
Even at the $0.10 minimum, superfecta boxes with many horses carry significant ticket cost. The combination count, not the base bet, is what drives the total.
The minimum superfecta box uses 4 horses, creating 24 combinations (4 × 3 × 2 × 1 = 24). At a $0.10 base, the ticket costs $2.40. At $1 base it costs $24.
Superfecta boxes produce far more combinations than exactas or trifectas. The $0.10 minimum base keeps ticket costs more manageable while still allowing broad coverage. A $1 base superfecta with 6 horses costs $360, while a $0.10 base costs $36.
A 5-horse superfecta box has 120 combinations (5 × 4 × 3 × 2 = 120). At $0.10 base that costs $12. At $1 base it costs $120.
A straight superfecta requires one exact finishing order for the top four positions. A superfecta box covers every four-horse finishing order among your selected horses, at a significantly higher cost. The box hits as long as your horses fill the top four spots in any covered order.
No. A superfecta box increases coverage but does not improve expected value. The payout depends on the pari-mutuel pool, track takeout, and other winning tickets. More combinations raise the ticket cost without affecting what the pool holds or what the track takes from it.
Run the cost, compare it against your bankroll, and remember: more combinations increase cost, not edge.
