Daily Double Calculator: Multi-Race Horse Betting (2026)
Daily Double Calculator: Master Multi-Race Betting
The daily double challenges you to pick winners in two consecutive races—harder than a single win bet but with bigger payouts. Our free calculator shows bet costs, combinations, and helps you build strategic multi-race wagers.
What Is a Daily Double?
A daily double requires selecting the winners of two designated consecutive races. Both horses must win for your ticket to pay—no partial credit for one winner.
Quick Answer: A straight daily double picks one horse in each race. A daily double "wheel" covers multiple horses in one or both races. A $1 bet with 3 horses in Race 1 and 4 horses in Race 2 costs $12 (3 × 4 combinations). Use our calculator to see exact costs for any combination.

Daily Double Combination Formulas
Basic Calculation

Cost = Combinations × Base bet
Quick Reference Table

Wheel Calculations
Part Wheel: Specific horses in both legs
- 3 horses × 4 horses = 12 combinations
Full Wheel (one leg): ALL in one race, specific in other
- 10-horse field × 2 picks = 20 combinations
Real-World Daily Double Examples
Example 1: Conservative Approach
Analysis:
- Race 1: Strong favorite (#3) looks unbeatable
- Race 2: Competitive field, like #2, #5, #8
Bet: $2 daily double: 3 / 2, 5, 8 Cost: 1 × 3 = 3 combinations × $2 = $6 Strategy: Use confidence in Race 1 to afford coverage in Race 2
Example 2: Spreading Both Legs
Analysis:
- Race 1: Two horses stand out (#1, #4)
- Race 2: Three contenders (#3, #6, #9)
Bet: $1 daily double: 1, 4 / 3, 6, 9 Cost: 2 × 3 = 6 combinations × $1 = $6 Coverage: Win if either 1 or 4 wins Race 1 AND any of 3, 6, or 9 wins Race 2
Example 3: Longshot Key
Analysis:
- Race 1: You love a 12-1 longshot (#7)
- Race 2: Wide open field
Bet: $1 daily double: 7 / ALL Cost: 1 × (field size) = ~10 combinations × $1 = $10 Strategy: If your longshot wins, any Race 2 winner gives you a payout
Example 4: Full Coverage
Analysis: Both races are unpredictable
Bet: $0.50 daily double: 1, 3, 5, 7 / 2, 4, 6, 8 Cost: 4 × 4 = 16 combinations × $0.50 = $8 Trade-off: Wide coverage but smaller base bet means smaller payout
Daily Double Strategy Tips
When to Use Daily Doubles
✅ Strong opinion in one race: Key your confident pick, spread the other ✅ Value hunting: Payouts often exceed multiplying win prices ✅ Carryover pools: Double pools sometimes carry over ✅ Early races: Less public money = potential overlays
Building Effective Tickets
Pyramid Structure:
- Use 1-2 horses in your confident race
- Use 3-5 horses in your uncertain race
- Keeps costs manageable while maximizing coverage
Key Horse Strategy:
- Identify the most likely winner
- Key that horse with several in the other leg
- Example: 3 / 1, 2, 5, 7, 9 = 5 combinations
Comparing to Parlay
Daily double vs. betting two races separately:
| Approach | Pros | Cons |
|---|---|---|
| Daily Double | Often higher payout, single pool | Must hit both |
| Separate Win Bets | Can press after Race 1 | Lower combined payout |
Rule of thumb: Daily doubles usually offer better value than parlaying win bets.
Payout Dynamics
How Payouts Are Calculated
Daily double pools work like other pari-mutuel bets:
- All bets go into pool
- Track takes ~15-20%
- Remaining money divided among winning tickets
Typical Payout Ranges
| Winning Combo Type | Payout Range |
|---|---|
| Favorite + Favorite | $5-$20 |
| Favorite + Mid-odds | $15-$60 |
| Favorite + Longshot | $40-$200 |
| Mid-odds + Mid-odds | $30-$150 |
| Longshot + Longshot | $200-$2,000+ |
Payout vs. Win Bet Multiplier
Sometimes daily double pays more than multiplying win odds:
Example:
- Horse A wins Race 1 at 3-1 ($8 on $2)
- Horse B wins Race 2 at 4-1 ($10 on $2)
- Multiplied: $8 × ($10/$2) = $40
- Actual daily double: $52
The $12 difference is "overlay value" in the double pool.
Common Daily Double Mistakes
-
Over-Spreading: Too many horses = small base bet = disappointing payout even when correct
-
Ignoring Race Analysis: Daily doubles require handicapping both races, not just picking names
-
Using All/All: Betting every combination is almost always -EV due to track take
-
Forgetting Late Scratches: Monitor entries; scratches after betting may leave you with unwanted combinations
-
Not Comparing to Win Bets: Sometimes separate win bets offer better value
