工作原理
Bookmakers build a margin (the vig or overround) into their prices, so the implied probabilities of all outcomes add up to more than 100%. Removing it shows what the market actually thinks.
Enter the odds of every outcome of one market. The tool scales the implied probabilities down proportionally until they sum to 100% and shows the fair odds, which are handy for judging whether another price is good value.
常见问题
What is the margin in a betting market?
The amount by which implied probabilities exceed 100%. Odds of 1.90 on both sides of a coin-flip market give 52.6% + 52.6% = 105.3%, a margin of about 5.3%.
Which method does this calculator use?
The proportional (multiplicative) method: each implied probability is divided by their total. Other methods spread the margin differently, which matters mostly for long shots.
Can I use it for three-way markets?
Yes. Add a third outcome for a draw. Any market with two or more mutually exclusive outcomes works.
