Decimal odds tell you two things at once: how much you win and how likely the bookmaker thinks the outcome is. Once you can convert between the two you can spot prices that are worth taking and avoid the ones that are not.
How Decimal Odds Work
Multiply your stake by the decimal odds to get the total return, stake included. A ₹1,000 bet at 1.85 returns ₹1,850, of which ₹850 is profit. Odds below 2.00 mean the outcome is more likely than not; odds above 2.00 mean it is the underdog.
Turning Odds Into Probability
Divide 1 by the decimal odds. Odds of 1.85 imply a probability of 54 percent; odds of 2.10 imply 47.6 percent. Add both sides of a two-way market together and you get the bookmaker’s margin: 54 + 47.6 = 101.6, so the margin is 1.6 percent.
| Decimal odds | Implied probability | Profit on ₹1,000 |
|---|---|---|
| 1.50 | 66.7% | ₹500 |
| 1.85 | 54.1% | ₹850 |
| 2.00 | 50.0% | ₹1,000 |
| 2.50 | 40.0% | ₹1,500 |
| 3.40 | 29.4% | ₹2,400 |
What a Good Price Looks Like
- Estimate the real probability yourself before you look at the odds.
- Convert the odds to a probability and compare. If your number is higher, the price has value.
- Ignore prices with a margin above 8 percent; player props and special markets often carry it.
- Track your bets in a spreadsheet: closing-line value tells you whether you are beating the market over time.
Parlays Multiply Both Odds and Margin
A three-leg accumulator at 1.80 each pays 5.83, but the margin compounds too. The Parlay Boost offsets part of that, which is why it is worth using on accumulators of three legs or more. Details are on the bonuses page.
