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.
- An NFL money line of +200 means that you would win $200 on a successful $100 wager. That's also equivalent to fractional odds of 2/1, decimal odds of 3.00, and implied odds of 33.33 percent. A negative money line of -200 means that you would have to wager $200 in order to win $100.
- 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.
- Convert betting odds to probability. Now we want to see what those odds mean in terms of probability. There is another simple formula that takes the numbers in a fractional odds presentation, adds them together and then divides that total by the second number to give a probability factor. So for Barcelona at 4/6 that is 4+6=10 and then 10 divided by 6 = 1.6 then multiply that by 100 = 60%.
- The odds of rolling a 6 is 1:5. This is because there is 1 event (rolling a 6) that produces the specified outcome of 'rolling a 6,' and 5 events that do not (rolling a 1,2,3,4 or 5). The odds of rolling either a 5 or 6 is 2:4. This is because there are 2 events (rolling a 5 or 6) that produce the specified outcome of 'rolling either a 5 or 6.
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.'

This calculator will convert 'odds of winning' for an event into a probability percentage chance of success.
Odds, are given as (chances for success) : (chances against success) or vice versa.
If odds are stated as an A to B chance of winning then the probability of winning is given as PW = A / (A + B) while the probability of losing is given as PL = B / (A + B).
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
For 4 to 48 odds for winning;
Probability of:
Winning = (0.0769) or 7.6923%
Losing = (0.9231) or 92.3077%
'Odds for' winning: 1:12 (reduced from 4:48)
'Odds against' winning: 12:1 (reduced from 48:4)
