Decimal odds are the default format on most Philippine sportsbooks, and they are the easiest to work with once you know one rule: stake × odds = total return. This guide shows how to read decimal odds, convert them to implied probability and other formats, spot the bookmaker’s margin and work out parlay returns, with examples and ready-made tables.
How do you read decimal odds?
Odds of 2.50 mean every ₱1 staked returns ₱2.50 if the bet wins: your ₱1 back plus ₱1.50 profit. Odds can never be below 1.00, and 1.00 would mean no profit at all.
| Odds | ₱100 stake: total return | Profit | Implied probability |
|---|---|---|---|
| 1.25 | ₱125 | ₱25 | 80.0% |
| 1.50 | ₱150 | ₱50 | 66.7% |
| 1.80 | ₱180 | ₱80 | 55.6% |
| 2.00 | ₱200 | ₱100 | 50.0% |
| 2.50 | ₱250 | ₱150 | 40.0% |
| 3.00 | ₱300 | ₱200 | 33.3% |
| 5.00 | ₱500 | ₱400 | 20.0% |
| 10.00 | ₱1,000 | ₱900 | 10.0% |
How do you play, step by step?
- Multiply your stake by the odds: ₱250 × 1.72 = ₱430 total return.
- Subtract the stake to get profit: ₱430 − ₱250 = ₱180.
- Divide 1 by the odds for implied probability: 1 ÷ 1.72 ≈ 58.1%.
How do you find the bookmaker’s margin?
Add the implied probabilities of every outcome in a market. A fair market totals exactly 100%; real markets total more.
| Outcome | Odds | Implied % |
|---|---|---|
| Team A | 1.91 | 52.4% |
| Team B | 1.91 | 52.4% |
| Total | 104.7% |
The extra 4.7% is the overround. A lower total means a fairer price. To estimate the “fair” probability of each side, divide its implied percentage by the total: 52.4 ÷ 104.7 ≈ 50%.
How do you convert between odds formats?
| Decimal | Fractional | American | Hong Kong |
|---|---|---|---|
| 1.50 | 1/2 | −200 | 0.50 |
| 1.80 | 4/5 | −125 | 0.80 |
| 2.00 | 1/1 (evens) | +100 | 1.00 |
| 2.50 | 3/2 | +150 | 1.50 |
| 3.00 | 2/1 | +200 | 2.00 |
| 5.00 | 4/1 | +400 | 4.00 |
- Fractional = decimal − 1, written as a fraction.
- American: if decimal ≥ 2.00, (decimal − 1) × 100 with a plus sign; if below 2.00, −100 ÷ (decimal − 1).
- Hong Kong = decimal − 1 (profit per unit).
How do decimal odds work in parlays?
For a parlay of independent selections, multiply the odds. Three legs at 1.80, 1.90 and 2.10 give 1.80 × 1.90 × 2.10 = 7.182. A ₱100 stake returns ₱718.20 if all three win. The implied chance is 1 ÷ 7.182 ≈ 13.9%, and the margin of each leg compounds. Same-match combinations are priced differently; see our bet builder guide.
How do decimal odds work with handicaps and totals?
Handicap and over/under markets use the same maths. Basketball spreads are often priced near 1.90 on each side. Asian handicap quarter lines (like −0.25) split your stake across two lines, so half could win and half push.
Which mistakes are common?
| Mistake | Correct approach |
|---|---|
| Treating the return as profit | Subtract the stake to get profit |
| Thinking low odds are “safe” | 1.25 still loses about 1 time in 5 by its own implied chance |
| Ignoring the margin | Add the implied probabilities and compare markets |
| Confusing Hong Kong and decimal | Hong Kong = decimal − 1 |
Odds vocabulary in Filipino
You may hear logro for odds, llamado for the favourite (lower odds) and dehado for the underdog (higher odds). More terms are in our Tagalog betting glossary.
Worked examples
- Favourite: ₱500 at 1.40 returns ₱700, a ₱200 profit. Implied chance 71.4%.
- Underdog: ₱200 at 4.20 returns ₱840, a ₱640 profit. Implied chance 23.8%.
- Comparing prices: Two sites offer 1.85 and 1.95 on the same side. On ₱1,000, the returns are ₱1,850 and ₱1,950. The better price adds ₱100 to the same winning bet.
How does implied probability compare with your own estimate?
Implied probability tells you what the price assumes, not what will happen. If you believe a team’s real chance is higher than the implied figure, the price looks generous to you; if lower, it looks short. Be honest that your estimate can be wrong. Margins mean the average bet still loses over time, so treat any estimate as an opinion, not an edge.
How are push, void and dead-heat bets settled?
| Result | Return with decimal odds |
|---|---|
| Win | Stake × odds |
| Lose | ₱0 |
| Push / void | Stake returned (odds treated as 1.00) |
| Half win (Asian quarter line) | Half stake × odds + half stake returned |
| Half loss | Half stake returned |
| Dead heat (tie for a position) | Stake divided by the number tied, then × odds |
In a parlay, a void leg is usually treated as odds of 1.00, so the parlay continues with the remaining legs. Check your operator’s rules.
Quick reference
- Return = stake × odds
- Profit = stake × (odds − 1)
- Implied % = 100 ÷ odds
- Parlay odds = odds₁ × odds₂ × …
- Overround = sum of implied % − 100
Why are decimal odds popular in the Philippines?
Decimal odds include the stake in one number, so there is no plus/minus sign to interpret and no fraction to convert. That makes comparing prices across markets quick: the higher number always pays more for the same stake. Most Asian-facing books also offer Hong Kong or Malay formats, but decimal remains the most common default on Philippine-facing sites, and it is the easiest format for multiplying parlay legs together.
Practice questions
- ₱300 at 2.20: what is the profit? ₱360.
- Odds of 1.60: what is the implied chance? 62.5%.
- Two legs at 1.50 and 2.00: what are the parlay odds? 3.00.
Tip: when a price looks unusually high compared with other markets, check the market rules first. It may be a different line, period or settlement rule, not a better deal.
