  1. The odds converter tool in this page will convert odds from any of the three main formats into the other formats. It will also calculate the relevant implied probability too. To use it, simply enter the odds you wish to convert in the appropriate box, and then click the “Convert Odds” button.
  2. When reporting the results from a logistic regression, I always tried to avoid reporting changes in the odds alone. What does an 18% increase in odds ratio mean? This number doesn't make sense to me intuitively, and I certainly don't expect this n.

Calculator Use

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.

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.'

Probability Formulas:

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)

Percent, an abbreviation of per centum meaning per hundred, is how we express a number as a fraction of 100. Some of us use percentages daily, whether in mathematics or engineering fields or calculating what to tip the waiter or waitress after eating out. The basics are pretty simple, really.

MathsIsFun.com perhaps has the easiest way of explaining it, describing that when you say percent you’re really saying 'per 100' with:

  • 100% meaning 100 per 100, or all
  • 50% meaning 50 per 100, or half
  • 25% meaning 25 per 100, or a quarter
  • 10% meaning 10 per 100, or a tenth
  • etc., etc.
