Ballpark, what fraction of a rocket launch fuel energy need to orbit is to overcome atmospheric drag as opposed to overcoming gravity? Anyone know off the top of your head?

Ballpark, it’s about 9.5 km/s of delta v needed to get to ISS orbit (400 km). Of that 9.5 km/s ~1.5 km/s is to counteract drag. Translating that to fuel in the rocket equation should be pretty ez.
