how much the wind affects your ball depends on your irons and ball trajectory and spin.
in general the longer the ball is in the air the more the wind will affect it. both in distance and in direction.
elevation take the feet. divide by 3. add that to the distance. (ballpark) there are tweeks.
de-elevation take the feet and divide by 4. (some will divide by 3) once again a ballpark figure.
strong crosswinds consider offdinging into the wind slightly.
those are all tips. you are going to have to adapt them to your game and change stuff accordingly.
The question you asked is the hardest to answer.
If we had a perfect mathematical answer we'd be even better.
