Quick answer: a parlay pays your stake multiplied by the odds of every leg, so ₱100 on three legs at 1.80, 1.90 and 2.10 returns ₱718.20 if all three win. Use the calculator below to work out any parlay, convert odds between decimal, fractional, American, Hong Kong, Malay and Indo formats, and check how big the bookmaker’s margin is on a market.

How to use the parlay calculator
- Enter your stake in pesos.
- Pick the odds format your betting site shows. Most Philippine sites default to decimal, while Asian handicap markets often show Hong Kong, Malay or Indo odds.
- Type the odds of each leg. Add up to 15 legs.
- Once matches finish, set each leg to Win, Void or Lost to see what the parlay actually pays.
If you switch the odds format, the calculator converts the odds you already typed, so you can paste odds from one site and compare them with another.
How a parlay payout is calculated
A parlay (also called an accumulator or multi) combines several bets into one. The winnings from each leg roll onto the next, so the decimal odds multiply:
Return = stake × odds of leg 1 × odds of leg 2 × odds of leg 3 …
With ₱100 on 1.80, 1.90 and 2.10, the combined odds are 1.80 × 1.90 × 2.10 = 7.182. The return is ₱718.20, which is ₱618.20 profit plus your ₱100 stake. If any leg loses, the whole parlay loses. If a leg is void (for example, a match is postponed), most bookmakers count it as odds of 1.00 and pay the parlay on the remaining legs.
Why parlays are harder to win than they look
Every price includes a bookmaker margin. On a single bet, a typical 5% margin means you get back about 95 centavos for every peso of fair value. In a parlay those margins multiply: on four legs you keep only about 82% of fair value, so the bookmaker’s edge grows to around 18%. The calculator shows this for your own parlay.
That is why a parlay of “safe” favourites still loses often. Three picks that each win 70% of the time all win together only about 34% of the time. Promotions such as accumulator insurance and odds boosts soften this a little, but they do not remove it.
The six odds formats in one minute
| Format | Same price shown as | How to read it |
|---|---|---|
| Decimal | 1.85 | Total return per ₱1 staked, stake included |
| Fractional | 17/20 | Profit per unit staked: win ₱17 for every ₱20 |
| American | -118 | Minus: stake needed to win ₱100. Plus: profit on a ₱100 stake |
| Hong Kong | 0.85 | Profit per ₱1 staked (decimal minus 1) |
| Malay | 0.85 | Positive: profit per ₱1. Negative: stake needed to win ₱1 |
| Indo | -1.18 | Like American odds divided by 100 |

What the margin checker tells you
Enter the odds for every outcome of one market, such as home, draw and away. The implied chances of all outcomes add up to more than 100%, and the extra is the bookmaker’s margin. A lower margin means better value for you. Big football matches and Asian handicap lines often run under 3%, while smaller leagues, props and live markets can go well above 7%. The checker also shows the “fair” odds with the margin removed, so you can see how much each price has been shaded.
Frequently asked questions
How do I calculate parlay odds?
Convert each leg to decimal odds and multiply them together. Three legs at 1.80, 1.90 and 2.10 give combined odds of 7.18. Multiply by your stake to get the total return.
What happens to my parlay if one game is postponed?
Usually that leg is made void and counted as odds of 1.00, so the parlay pays on the other legs. Rules differ between bookmakers and sports, so check the site’s own settlement rules.
Are Malay and Indo odds the same as Hong Kong odds?
They describe the same prices in different ways. Hong Kong odds show the profit per ₱1. Malay odds match Hong Kong odds up to 1.00 and turn negative above that. Indo odds are American odds divided by 100. The converter shows all of them side by side.
Is there a maximum payout on parlays?
Many bookmakers cap the amount a single bet can win, and some limit the number of legs. The calculator shows the full mathematical payout, so check the site’s limits before placing a large parlay.
Does the calculator save my bets?
No. Everything runs in your browser and nothing is sent anywhere. It only remembers which odds format you chose last time.
Final thoughts
A calculator tells you what a bet pays, not whether it will win. Use it to compare prices, to see how quickly parlay odds stack up against you, and to keep stakes small on long shots. If you are new to betting, start with how to place your first sports bet.
