This is for young galaxies....if you want to find the rate of star formation in the mature galaxies (and hence a much better determination of the values within the Drake equation), you need to study those areas of star formation within these galaxies. From doing so, astronomers have determined that the Milky Way produces 3-5 solar masses on new stars per year. It turns out to about one star of a solar mass per year...most of the others are smaller stars.
Interestingly, Andromeda produces 1 solar mass of stars per year.
