Calculator Use
1 1 Odds Mean
Convert stated odds to a decimal value of probability and a percentage value of winning and losing. This calculator will convert 'odds for winning' an event or 'odds against winning' an event into percentage chances of both winning and losing.
10/1 Odds Meaning
Be careful if you are using sports teams odds or betting odds. If you see that the Patriots super bowl odds are 9/2, that is most likely 'odds against' and should be entered in the calculator with 'Odds are: against winning.'
When playing a lottery or other games of chance be sure you understand the odds or probability that is reported by the game organizer. A 1 in 500 chance of winning, or probability of winning, is entered into this calculator as '1 to 500 Odds are for winning'. You may also see odds reported simply as chance of winning as 500:1. This most likely means '500 to 1 Odds are against winning' which is exactly the same as '1 to 500 Odds are for winning.'

- Odds of 4/1 would imply that the bettor stands to make a £400 profit on a £100 stake. If the odds are 1/4, the bettor will make £25 on a £100 stake. In either case, having won, the bettor always receives the original stake back; so if the odds are 4/1 the bettor receives a total of £500 (£400 plus the original £100).
- Fractional odds are some of the most simple to understand, as they present your potential winnings as a fraction of the money you stake: while the denominator represents the amount bet, the numerator is the amount your stake will yield in a winning bet. For example, odds of 1/1 mean you’d get a return of $20 for a winning $10 bet.
$ To Win. 1.1 = $ Needed to Bet ($100. 1.1 = $110) As you can see, understanding the -110 in sports betting is pretty basic once you realize what it represents. You can also apply this knowledge to other odds as well, such as the money line. If $10 is bet at odds of 3/1, the potential profit is $30 ($10 x 3) and the total returned is $40 ($30 plus the $10 stake). Implied Probability. Odds correlate to probability. A 4/1 bet is expected to win one in every five attempts, therefore the probability is 20%. Odds Conversion Table. Fractional Decimal American Implied Probability; 1.

For example, you win a game if you pull an ace out of a full deck of 52 cards. Pulling any other card you lose. The chance of winning is 4 out of 52, while the chance against winning is 48 out of 52 (52-4=48). Entering A=4 and B=48 into the calculator as 4:48 odds are for winning you get
