Fuel mass as related to delta v

Question

When calculating my fuel mass for the delta v equations, do i need to add the oxidizer mass together with the liquid fuel mass to get the fuel mass, or do i just go with the liquid fuel mass itself?

Instead of calculating it every time you can install either mechjeb or kerbal engineer mods to see the dV values. That being said you need both oxidizer + liquid fuel mass for the calculation.

Also, an easier way of getting dry and wet mass is looking at the total mass of a stage, then removing the fuel and looking at the total mass again.

Just as a precaution: Fuel tanks have a dry mass of their own. So make hure to count them in aswell.
