Hopefully what you are looking for is the rule of thumb that the max drift will be about half the wind, so if e.g. you have a 20kt crosswind component, the drift will be 10 degrees.
This is pretty close for a standard school plane going at about 100kt. For 150kt the max drift is about 1/3 of the crosswind.
These simple rules are as accurate as the winds aloft forecast.
