This Relative Risk and Odds Ratio calculator allows you to determine the comparative risk of the occurrence of a significant event (or outcome) for two groups. For example, suppose the members of one group each eat a kilo of cheese every day, and the members of another group eat no cheese...
You can use this relative risk calculator to find out that, for the confidence level of 95%, the confidence interval is between 1.02 and 62.7. It means you can be 95% sure that the real relative ratio lies between these two numbers. That doesn't look like an exact answer, does it?
