Parlay Calculator Quickly Work Out Your Payout
When calculating No Vig odds, the favourites’s implied probability may be inflated. Bookmakers build their profit margin into the odds they offer, meaning that the sum of the implied probabilities of all possible outcomes usually exceeds 100%. The aim being for bookmakers to try and unify their odds, especially when a big bet has been placed. Tic-tac is a method used ostensibly by bookmakers at horse racing meetings in the UK to communicate the value of odds of horses between them. For example, if you wanted to back France to win FIFA World Cup in 2026, you may find that the French are 5/1 to win the World Cup with most bookmakers, but they may also be available at odds of 7/1 with another. But what happens to them depends upon how much money is bet on the different outcomes for a betting market.
Odds ratio – Confidence Interval
For conversion of fractional odds to decimal take the first figure and divide it by the second figure then add 1.00. Punters usually only find themselves in situations where they are trying to convert odds between formats, for example whilst on holiday or traveling and betting outside their home countries. Sometimes decimal prices are quoted to three decimal places, so if you place a £10 stake at 4.755 your total return on a correct bet is exactly £47.55, meaning you made a £37.55 profit.
- This means that you have to take each horse’s decimal odds and divide 1 by it, then add all those numbers together.
- We consider here what the odds of aspiring to remain in FTE are separately for boys and girls, i.e. conditional on gender.
- This means that you must consistently make bets at odds that are bigger than they should be.
- This calculator uses the following formulae to calculate the odds ratio (or) and its confidence interval (ci).

But I’ll focus on odds as a fraction for my examples, as it’s easier to recognise and understand. The coin toss is a 50/50 chance, so the odds should be even money heads and even money tails. As there are only two options, the probability of the toss resulting in heads is 50%, and the probability of it landing on tails is 50%. Major bookmakers allow you to wager on the result of a coin toss at the start of a football or cricket match. Probability refers to the likelihood of an outcome.
