Hong Kong Odds: The Simplest Asian Format — Explained with Calculations
Key Takeaways
- Hong Kong odds show profit per 1 unit staked — always positive, regardless of whether the outcome is favourite or underdog
- Conversion to decimal is a single step: HK odds + 1 = decimal odds. HK odds 0.93 = decimal 1.93.
- HK odds are numerically identical to positive Malay odds for outcomes below even money — the difference appears only in how favourites are expressed
- Even money (decimal 2.00) = HK odds 1.00. Odds above HK 1.00 are underdogs; odds below HK 1.00 are favourites in the traditional sense
- HK odds are the default display on Hong Kong horse racing platforms and many Macau-facing books; available as a display option on SBOBET and PS3838
Hong Kong odds are the most intuitive Asian odds format for bettors already familiar with decimal odds. The format emerged from Hong Kong horse racing, where odds have traditionally been quoted as profit per dollar staked. This profit-only convention makes HK odds particularly easy to read: the number tells you directly how much you gain if your bet wins, with your original stake always returned on top.
This guide covers HK odds mechanics, return calculations, conversion formulas, comparison with other Asian formats, and practical context for when you will encounter HK odds on betting platforms.
How Hong Kong Odds Work
The definition is simple: HK odds represent the profit returned per 1 unit staked when a bet wins. The original stake is always returned separately.
- HK odds 1.00 = even money — you profit exactly 1 unit for every 1 unit staked (decimal 2.00)
- HK odds above 1.00 = underdog prices — profit exceeds stake
- HK odds below 1.00 = favourite prices — profit is less than stake, but stake is still returned in full on a win
Unlike Malay odds, HK odds never go negative. A heavy favourite at decimal 1.30 is expressed as HK odds 0.30 — you profit €30 for every €100 staked. A heavy underdog at decimal 3.50 is HK odds 2.50 — you profit €250 for every €100 staked. Both positive, both straightforward.
Calculating Returns from HK Odds
Two formulas cover everything:
Profit: Stake × HK odds
Total return: Stake + (Stake × HK odds) = Stake × (HK odds + 1)
Or equivalently: Total return = Stake × Decimal odds
(Since Decimal = HK + 1)
Example 1: Chelsea −0.25 AH at HK odds 0.93, stake €500
Profit: €500 × 0.93 = €465
Total return: €500 + €465 = €965
Loss: −€500
Example 2: Arsenal +0.5 AH at HK odds 0.88, stake €1,000
Profit: €1,000 × 0.88 = €880
Total return: €1,000 + €880 = €1,880
Example 3: Heavy favourite at HK odds 0.35, stake €2,000
Profit: €2,000 × 0.35 = €700
Total return: €2,000 + €700 = €2,700
Decimal equivalent: 0.35 + 1 = 1.35
HK Odds Conversion to Other Formats
HK to Decimal
Formula: Decimal = HK + 1
This is the simplest conversion in any odds format comparison. No division, no sign changes.
HK to Malay
For prices at or below even money (HK ≤ 1.00, decimal ≤ 2.00): Malay = HK (identical)
For prices above even money (HK > 1.00, decimal > 2.00): Malay = −(1/HK)
HK to Indonesian
For prices at or below even money: Indo = HK (identical)
For prices above even money: Indo = −(1/HK) (identical to Malay for these prices)
| HK Odds | Decimal | Malay | Indonesian | €100 profit (on win) |
|---|---|---|---|---|
| 0.30 | 1.30 | −3.33 | −3.33 | €30 |
| 0.50 | 1.50 | −2.00 | −2.00 | €50 |
| 0.85 | 1.85 | +0.85 | +0.85 | €85 |
| 0.93 | 1.93 | +0.93 | +0.93 | €93 |
| 1.00 | 2.00 | +1.00 | +1.00 | €100 |
| 1.20 | 2.20 | −0.83 | −0.83 | €120 |
| 2.00 | 3.00 | −0.50 | −0.50 | €200 |

For bettors familiar with decimal odds, HK odds require only a single mental shift: the displayed number is the profit component only, not the total return. Once you internalise "HK 0.93 = profit 93% of stake on a win", you can instantly calculate returns and compare prices across books that use different display formats.
The simplest practical test: if you can quickly read "HK 0.85 means you profit €85 on a €100 bet", HK odds are already intuitive for you. If you work through it as "HK 0.85 + 1 = decimal 1.85, which is a 46% implied win probability at a book with 2% margin", you're using the format correctly.
HK Odds vs Decimal Odds: Mental Model
Decimal 1.93 = HK 0.93
Mental model in decimal: "If I bet €100, I get €193 back on a win"
Mental model in HK: "If I bet €100, I profit €93 on a win"
Both are correct — the HK framing is useful when you want to think about profit (e.g., commission calculations) rather than total return. Many professional bettors prefer to track P&L in profit terms, making HK odds a natural fit for mental accounting.
Where to Use the Asian Odds Converter
For any price you need to convert quickly, the Asian odds converter handles all four formats simultaneously. Enter any format and receive all equivalent expressions. Particularly useful when:
- Comparing prices between a book that displays HK odds and one showing decimal
- Converting odds from a broker's display into a format your calculator or spreadsheet expects
- Verifying mental conversions during live line shopping
Frequently Asked Questions
Are Hong Kong odds the same as decimal odds minus 1?
Yes, exactly. HK odds = Decimal odds − 1. Or equivalently: Decimal odds = HK odds + 1. They represent the same price in different ways — decimal includes the returned stake in the multiplier, HK shows only the profit component. This makes conversion between the two formats trivial compared to any other odds format pair.
Do any major bookmakers use HK odds by default?
HK odds are default on many Hong Kong horse racing platforms (HKJC and similar). In sports betting, they are most commonly an available option rather than the default — SBOBET, PS3838, and other major Asian books allow users to select HK odds in display settings. Some Macau-facing books use HK odds as default for their sports markets, reflecting regional betting convention.
What is HK odds 0 or negative HK odds?
HK odds cannot be 0 or negative in a legitimate market — a 0 value would imply a certainty (you profit nothing, you break even), and negative values would mean the book owes you money if you lose, which is impossible. If you see what appears to be a 0 or negative HK value, it is likely a display error or a misread from a Malay or Indonesian odds display. HK odds always range from just above 0 (very heavy favourites) to theoretically unlimited for extreme underdogs.
How do I calculate the implied probability from HK odds?
Implied probability = 1 / (HK odds + 1) = 1 / Decimal odds. For HK odds 0.93: implied probability = 1 / 1.93 = 51.8%. This includes the bookmaker's margin, so the true "fair" implied probability is slightly lower. To see a two-way market (both sides) add both implied probabilities — the total above 100% is the margin. For HK 0.93 / 0.93 (equal-priced AH market): 51.8% + 51.8% = 103.6%, implying a 3.6% book margin.
