Mix parlay calculator for combined odds and the chance every leg lands
A mix parlay pays only when every leg wins, so its odds are the decimal odds of all the selections multiplied together. Three legs at 1.85, 1.90 and 2.00 give combined odds of 7.03, which turns a RM 10 stake into RM 70.30. The calculator also shows the implied chance of the whole ticket landing, and that number is usually far smaller than it feels.

Enter the decimal odds for each leg of the ticket
Fill in one box per selection on your ticket. Leave the remaining boxes empty if you have fewer than five legs; only filled boxes are counted. The stake is what you put on the whole ticket, not on each leg.
The calculator works in decimal odds, sometimes called European odds. If your bet slip shows Malay, Hong Kong or Indonesian odds, convert them first with the odds converter for Malay, Hong Kong, Indonesian and decimal formats.
- Odds must be 1.00 or higher. Anything lower is not valid decimal odds, and the results switch to a dash.
- Void legs: most sportsbooks treat a cancelled (void) leg as 1.00 and settle the ticket on the remaining legs. Enter 1.00 for that leg.
- Ticket limits: the minimum number of legs, the minimum odds per leg and the maximum payout are set by the sportsbook and shown on the bet slip.
Combined odds and ticket payout formulas
| Result | Formula |
|---|---|
| Combined odds | d1 × d2 × … × dn |
| Return if every leg wins | stake × combined odds |
| Net profit | stake × (combined odds − 1) |
| Implied chance every leg wins | (1 ÷ d1) × (1 ÷ d2) × … = 1 ÷ combined odds |
Worked example: 1.85 × 1.90 = 3.515, and 3.515 × 2.00 = 7.03. On a RM 10 stake the return is RM 70.30 and the net profit RM 60.30. If the second leg is voided, the odds drop to 1.85 × 1.00 × 2.00 = 3.70 and the return to RM 37.00.
Asian Handicap legs on quarter lines are a special case. Sportsbooks usually count a half win as (odds + 1) ÷ 2 and a half loss as 0.5, so a 1.90 leg that half wins counts as 1.45. The Asian Handicap calculator by final score shows how those outcomes are decided.
The chance of every leg winning, and why the real figure is lower
Implied probability is the chance built into a price: 1 divided by the decimal odds. For the example above that is 1 ÷ 1.85 = 54.05%, 1 ÷ 1.90 = 52.63% and 1 ÷ 2.00 = 50%. Multiply the three and you get 14.22%, roughly one winning ticket in seven.
The true chance is usually lower still, because every market carries a bookmaker margin. In a two-way market priced 1.90 on both sides, the implied probabilities add up to 105.26%, not 100%. If the two sides are genuinely even, each has a 50% chance rather than 52.63%. The calculator uses 1/odds because that is all a ticket tells you, so read the figure as a ceiling rather than a forecast.
One more caveat: selections from the same match are linked, which is why many sportsbooks refuse those combinations. Simple multiplication is only accurate when the legs are independent of each other.
Why each extra leg makes the ticket riskier
This table assumes every leg is priced at 1.90 with a true 50% chance, a balanced market with a normal margin. The numbers are an illustration, not real match data.
| Legs | Combined odds | Chance all win | Value versus fair odds | Average loss per RM 10 |
|---|---|---|---|---|
| 1 | 1.90 | 50.00% | 95.0% | RM 0.50 |
| 2 | 3.61 | 25.00% | 90.3% | RM 0.98 |
| 3 | 6.86 | 12.50% | 85.7% | RM 1.43 |
| 4 | 13.03 | 6.25% | 81.5% | RM 1.85 |
| 5 | 24.76 | 3.13% | 77.4% | RM 2.26 |
The payout grows quickly, but so does the margin: 0.95 is multiplied in again with every leg. At five legs the average loss is 22.6% of the stake, compared with 5% on a single bet. The guide to reading odds formats with examples explains where that margin comes from in each market.
What parlay numbers mean for a sports budget
A five-leg ticket with a 3.13% chance wins on average once every 32 tickets. Runs of 20 or 30 losing tickets in a row are normal and are not a sign that a win is due.
- Treat a parlay stake as money already spent on entertainment.
- Keep the stake small and fixed. Raising it, or adding legs to chase the last ticket, only raises the cost.
- If you want fewer swings, use fewer legs. The margin you pay drops as well.
Frequently asked questions
How are mix parlay odds calculated?
Mix parlay odds are the decimal odds of every leg multiplied together. Three legs at 1.85, 1.90 and 2.00 give 7.03. The return is the stake times the combined odds, so RM 10 becomes RM 70.30 if every leg wins. One losing leg loses the whole ticket.
What happens to a parlay if one leg is void?
Most sportsbooks count a void leg as odds of 1.00. The ticket carries on with the remaining legs, and the combined odds become smaller. The exact rules, including any minimum number of legs after a void, are in the sportsbook rules and on the bet slip.
Is a parlay better value than single bets?
No. A parlay pays more because it is less likely to win, and the bookmaker margin compounds with every leg. With five legs at 1.90 in balanced markets, the average loss is about 22.6% of the stake, against 5% for a single bet at the same odds.
Before you build a parlay ticket Check the odds, the leg limits and the maximum payout on the bet slip in your account. If you want to keep sports spending in check, set a deposit limit first in the account settings or through customer support.
