How much would you need to invest in order to make $1k a month in dividends?

Assuming the dividend per share is stable, x% is the current/desired dividend yield (annually)
Monthly =1k. Annually =12k

How much u need to invest =12k/x *100

E.g your dividend yield = 6%, u need to invest 200k

That's 12k a year. At a 4% dividend yield, you'll need a capital of 300k. At a 6% yield, you'll need 200k.
