I do not trust such figures, but they provide a rough estimate of the production of each missile.
20 Kalibr missiles per month = 240 Kalibr missiles per year
40 Kh-101 missiles per month = 480 Kh-101 missiles per year
30 Iskander-M ballistic missiles per month = 360 Iskander-M missiles per year
12 Iskander-K cruise missiles per month = 120 Iskander-K missiles per year
9 Kh-22/Kh-32 missiles per month = 108 Kh-22/Kh-32 missiles per year
4 Kinzhal per month = 48 Kinzhal per year
That's 115 missiles per month. 1,380 missiles per year. If you look at the monthly missile launch rates of OSINT analysts, you'll see that they average around 50-60 missiles per month.
Furthermore, according to the article, this is the Russians' stockpile in that period (fourth quarter of 2023):
