Horse Racing Odds and Payout Calculator
Odds of 5-2 mean a winning bet earns $5 for every $2 bet, so a $2 win ticket on a 5-2 horse returns $7.00: the $2 back and $5 of profit. The calculator turns any odds into that figure and the chance they imply, then shows where the odds come from, a pool of money with the track's share taken out first.
Odds, payouts and the pool
Odds on a tote board are the pool's, not a fixed price. Turn them into a payout, or start from the pool and watch takeout and breakage come out of it.
Type 5-2, 5/2, 2.5 (to 1) or even.
- Profit
- Working
- Chance the odds imply
- As decimal odds
The board rounds odds down, so the price paid is usually a little more than this. The odds are final only when the gates open, and a morning line is a forecast printed in the program, not a price anyone is paid at.
The track's rules
17.5% and 22% are Churchill Downs' 2026 rates. $2.10 is a common state minimum, and some states pay to the penny: check your state's rule.
How do you read odds like 5-2?
The first number is what you win; the second is what you bet to win it. At 5-2 a bet of $2 wins $5, and the payout on a $2 ticket adds the $2 back: $7.00. At 3-1 a $2 bet wins $6 and returns $8.00. Odds of 1-1 are called even money. Odds below even money, like 4-5, are called odds-on: $5 bet wins $4. The chance the odds imply is the second number over the two added together, so 5-2 implies 2 in 7, about 28.6%.
| Odds | $2 returns | Odds | $2 returns |
|---|---|---|---|
| 1-5 | $2.40 | 5-2 | $7.00 |
| 2-5 | $2.80 | 3-1 | $8.00 |
| 1-2 | $3.00 | 7-2 | $9.00 |
| 4-5 | $3.60 | 4-1 | $10.00 |
| 1-1 | $4.00 | 9-2 | $11.00 |
| 6-5 | $4.40 | 5-1 | $12.00 |
| 3-2 | $5.00 | 8-1 | $18.00 |
| 9-5 | $5.60 | 10-1 | $22.00 |
| 2-1 | $6.00 | 20-1 | $42.00 |
| 50-1 | $102.00 | 99-1 | $200.00 |
The real payout is usually a little higher than the table, because the tote board rounds the odds down to the next step it can show. Golden Tempo won the 2026 Kentucky Derby at 23-1, which the table would make $48.00 on $2, and paid $48.24.
Why do the odds keep changing?
American racing is pari-mutuel: every win bet on a race goes into one pool, the track takes its share, and what is left is divided among the tickets on the winner. The odds on the board are only the pool's current shape, recalculated as money comes in, so a horse at 5-2 when you bet can leave the gate at 2-1 and pay accordingly. The price you are paid is the one when the gates open, not the one when you bet.
The morning line printed in the program is something else again: the track oddsmaker's forecast of how the public will bet the race, set before any money is in the pool. Nobody is paid at the morning line, and the final odds can be far from it.
How do takeout and breakage come out of the pool?
Takeout is the share of every pool taken out before the winners are paid. At Churchill Downs it is 17.5% of the win, place and show pools and 22% of most others, according to its event information page. Say the win pool holds $100,000 and $20,000 of it is on your horse. Takeout leaves a net pool of $82,500. Divided by the $20,000 on the winner, that is $4.125 for each $1 bet. Prices are rounded down to a break point, often the dime, so the $1 price is $4.10 and the $2 payout is $8.20. The 2.5 cents lost on each dollar is breakage, which the track keeps too: $500 on this pool. The board would have shown 3-1.
Takeout is also why the odds on a board never add up. Turn every horse's odds into a chance and the chances total about 121% at 17.5% takeout, not 100%; the extra is the track's share. Over many races it means the bettors as a group get back less than they bet, which is worth keeping in mind with any bet.
Not every state rounds to the dime. Golden Tempo's $48.24 is not a multiple of 20 cents, so that pool was not broken to the dime. The calculator has a penny setting for that.
Why can't place and show prices be worked out from the odds?
A place bet pays if the horse finishes first or second, and a show bet if it finishes in the top three, and each has its own pool. In Kentucky, under 810 KAR 6:020, the money bet to place on the first two finishers is taken out of the net place pool and the profit left is split into two equal halves, one for each horse, each half then divided among that horse's place tickets. Show works the same way in thirds. So your horse's place price depends on which horse finished with it: running second to a heavily bet favorite pays less than running second to a long shot. The third panel of the calculator does it line by line. When two horses dead heat, the profit is divided again between them (dead heat rules).
