Aerospace Calculating delta v loss

  1. Oct 26, 2014 #1
    How do you calculate how much delta v is lost from gravity and atmospheric drag?
    I've been looking for days but I can't find anything that actually tells me how it's calculated.
    For example it takes 1.5 km/s - 2 km/s extra delta v for a low earth orbit because of drag loss, how was that number calculated?
