The Rocket Equation
Enter values for 3 of the variables and press recalc on the remaining one. (Note that the more popular specific impulse is being used with isp = Ve / 9.8)
Some easy values are provided in the drop down menus.
Alternatively, you can set delta-v, isp, and the stage parameters to do a fixed point calculation of a stage dry mass. (inert mass ratio = dry mass / propellant mass)
