A superfecta box on the Kentucky Derby requires you to pick the first four finishers in any order — and the cost climbs fast as you add horses. A five-horse superfecta box produces 120 combinations; at the common $0.10 base unit that comes to exactly $12.00.
How Does a Superfecta Box Work at Churchill Downs?
The superfecta requires selecting horses to finish 1st, 2nd, 3rd, and 4th in exact order. The "box" modifier removes the order requirement, so every possible finishing sequence among your picks counts as a winning ticket — at the cost of buying each combination separately.
Churchill Downs allows superfecta wagers as low as $0.10 per combination, which is why the bet is accessible even when you're boxing several horses. The pari-mutuel pool for the Derby superfecta is one of the largest in North American racing, which is part of why payouts can reach five or six figures in a year with a long-shot finisher in the top four.
How Much Does a Superfecta Box Cost?
The number of combinations in a superfecta box is calculated as n × (n−1) × (n−2) × (n−3), where n is the number of horses you select. Multiply the combination count by your base unit to get the total ticket price.
| Horses Boxed | Combinations | $0.10 Ticket Cost | $0.50 Ticket Cost | $1.00 Ticket Cost |
|---|---|---|---|---|
| 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 |
I keep this table in my notes every Derby week because it's surprisingly easy to miscount combinations in your head when you're at the window or tapping through an ADW app. For a live version you can adjust by wager type, try the Interactive Box Bet Cost Tool for Exacta, Trifecta & Superfecta on this site.
Why Are Superfecta Payouts So Hard to Predict?
Payouts are pari-mutuel — the pool minus takeout is divided by the number of winning tickets. Churchill Downs takeout rates on exotic wagers typically run in the 15%–25% range, per the Kentucky Horse Racing Commission, though the exact published schedule for each bet type should be confirmed at Churchilldowns.com before Derby day.
With 20 horses in the field, a four-horse sequence that includes even one double-digit longshot can produce very few winning tickets — sometimes just a handful nationwide — which is when six-figure payouts appear. Conversely, if the top four favorites run true to form, thousands of tickets cash and the per-ticket payout shrinks considerably. I experienced a mild version of this in a smaller stakes race: my $0.10 box paid less than a dollar because three favorites ran 1-2-3-4.
For the math behind how the pool translates to a dollar amount on your ticket, the How Pari-Mutuel Payouts Are Calculated for the Kentucky Derby guide walks through it step by step.
How Does a Superfecta Compare to a Trifecta Box?
The trifecta only asks for three finishers, so its box combinations are far fewer — a five-horse trifecta box has 60 combinations versus 120 for the superfecta. That makes the trifecta a reasonable midpoint if the superfecta cost feels steep. See How to Calculate a Kentucky Derby Trifecta Payout for the full breakdown. If you're newer to exotic wagering and want to start simpler, the Kentucky Derby Exacta Box cost chart covers the two-horse version first.
Which States Can Bet the Derby Superfecta Online?
Online superfecta wagering is available through licensed ADW platforms in most US states, but not all. Utah and Hawaii, for example, have no ADW authorization. The Which States Can Legally Bet the Kentucky Derby Online? page lists current access by state. Licensed apps like TwinSpires and TVG (FanDuel Racing) support superfecta box wagers; the Kentucky Derby Betting Apps comparison covers each platform's features side by side.
What About Taxes on a Big Superfecta Win?
If your superfecta pays $600 or more and the winnings are at least 300 times your wager, the ADW platform is required to issue a W-2G federal tax form, per IRS Topic No. 419. Federal backup withholding at 24% kicks in above $5,000 when the payout also clears the 300× threshold. The full picture is on the Are Kentucky Derby Winnings Taxable? page.
