Wind Correction Angle Formula?

Can someone please tell me what the wind-correction angle formula is? I believe it would be a trigonometric function. I need it to tie in with being able to also calculate ground speed. I'm building a Nav Log on Excel. I know there are a few Navlog's in Excel format out there that might already have it set up, but I want to make my own for fun. Any help?
 
Trig? Man, that's too hard. I just use an E6-B.

I hate the E6-B! LOL I'm trying to avoid using it (I know, bad, really bad)

I did that earlier today and couldn't find anything that included ground speed calculations, or that at least figured out the headwind component.
 
One rule of thumb I like to use when flying is: drift correction = crosswind component divided by airspeed in nm / minute. Its certainly not precise, but it seems to get the job done the few times I've used it.
 
The method I use is to determine the difference between your course and the wind direction. Add your wind aloft velocity and divide by 10, this should give you an approximate wind correction angle. It works for me.

For example, assuming 180 course, winds aloft are 230 at 15.
230-180=50
Add you wind velocity, so 50+15=65
Divide this number by 10, so 65/10=6.5
So 6.5 degrees (7 degrees) of wind correction to the right should hold your course.
