1.50 odds: what percentage is that? Decimal odds to probability table
From 1.20 to 10.00: converting decimal odds into implied probability, with the table ready made and the sum to do it yourself.
Pubblicato il 13 settembre 2026
Odds of 1.50 come to 66.7%. There is only one sum: 1 divided by the price, times a hundred. Below is the table already worked out for the commonest prices.
| Odds | Implied probability |
|---|---|
| 1.10 | 90.9% |
| 1.20 | 83.3% |
| 1.25 | 80.0% |
| 1.33 | 75.2% |
| 1.40 | 71.4% |
| 1.50 | 66.7% |
| 1.60 | 62.5% |
| 1.75 | 57.1% |
| 1.80 | 55.6% |
| 2.00 | 50.0% |
| 2.20 | 45.5% |
| 2.50 | 40.0% |
| 3.00 | 33.3% |
| 3.40 | 29.4% |
| 4.00 | 25.0% |
| 5.00 | 20.0% |
| 6.00 | 16.7% |
| 8.00 | 12.5% |
| 10.00 | 10.0% |
The values are calculated, not copied: 1 / 1.50 = 0.667, and so on for every row. If your price isn't in the table the sum is still the same — and it comes out easily in your head for the round ones: 2.00 is a half, 4.00 a quarter, 10.00 a tenth.
Careful: this is not the true probability
That 66.7% includes the bookmaker's margin, which lifts every percentage in a market: add up the three outcomes of a 1X2 and you get not 100 but 104-110, depending on the operator. To compare two bookmakers you first have to take the margin out, that is, divide each percentage by the total.
How much does it weigh? Measured on the feeds of 13 September 2026, on the full-time result the median margin runs from 8.77% to 9.98% depending on the operator: on a price of 1.50 that means a few points of implied probability more than the market actually assigns.
The reverse sum, which you need more often
If something looks 40% likely to you, the fair price is 1 / 0.40 = 2.50. It is the way to put a price on your own view before looking at the bookmaker's — and to notice when the two numbers are far apart.
