Cost equals valid combinations times base stake
Choose an exacta or trifecta box, a single-position key, or a part wheel, then multiply distinct finishing orders by the example amount per combination. Superfecta and quinella remain box-only. The calculator does not model coupled-entry rules or construct a GAMELIN wager.
A small change in coverage can multiply cost
A four-selection trifecta box contains 24 combinations. At a $0.50 base it costs $12. A five-selection box contains 60 and costs $30 at the same base. These examples show arithmetic, not a recommendation to use either ticket. Some tracks do not offer every type or base amount shown.
Key and part-wheel examples
An exacta key in first over four distinct others covers four combinations; at a $1 base it costs $4. A trifecta key in first over four others covers twelve ordered combinations and costs $6 at a $0.50 base. For a part wheel, enter program numbers separately in each finishing-position leg. The tool counts only orders with different interests in every position, even if an interest appears in more than one leg.
The same interest cannot finish in two positions, and a zero-combination wheel is invalid. Confirm how the operator treats coupled entries, scratches, minimum units and permitted wagers. The numeric program examples here are not selections.
The calculator cannot tell you the payout
This tool supplies no payout or pick. Price depends on the relevant pool and the winning combination, not just how many selections you made. Win odds do not determine an exacta, quinella, trifecta or superfecta payoff. More combinations do not prove better value.
Check the actual wagering rules
Minimum amounts, available pools, coupled interests and scratch treatment can differ. Confirm your ticket with the official track or operator before any purchase. Do not exceed a predetermined discretionary budget to add another runner. See the finishing-order guide for definitions.
Why boxes grow quickly
| Selections | Exacta box | Trifecta box | Superfecta box |
|---|---|---|---|
| 3 | 6 | 6 | Not possible |
| 4 | 12 | 24 | 24 |
| 5 | 20 | 60 | 120 |
| 6 | 30 | 120 | 360 |
Cost control is not payout analysis
The table can show that a five-runner superfecta box has five times as many combinations as a four-runner box. It cannot show whether either ticket is fairly priced. That requires joint finishing-order probabilities and the relevant exotic pool, neither of which is supplied by win odds alone.
Use the result as a ceiling check
Calculate the complete ticket before placing it, compare the total with a limit set in advance, and remove combinations instead of raising the budget. If GAMELIN’s race read says PASS, a larger exotic box does not reverse that decision. See the betting hub for the field-to-price workflow.
