If you're willing to just push the "I believe" button, ideal rocket equation does not use calculus. You won't understand where its derived, but all you need to use is a logarithm.

You'll need to know the starting mass, final mass, and specific impulse of your motors (which would be a look up or estimate). From there, its plug and chug.
