The equation that rules spaceflight. Your Δv budget depends only on exhaust velocity and the ratio of full-to-empty mass — and it's brutally logarithmic.

Governing equation

Δ v = v_{e} ln \frac{m _{0}}{m _{f}} = 3432 ln \frac{500}{100} = 5524 m/s

Reading this result: At 5524 m/s this stage cannot reach orbit; since Δv grows only with the log of mass ratio, big gains need a much emptier tank or higher Isp.
