Someone correct me here,
If you buy $10k worth of shares then you bought a number of shares for that price and it's the number of shares you get paid dividends on isn't it?
Example, you buy $10k of CBA shares and you receive 136 shares. You get paid a dividend on each of those shares..
So if CBA pay lets say, a $1 dividend then you get $136. Which of course is a percentage of your original $10k purchase but I don't think it's calculated how you said in your original post.
I could be wrong here but I understood it to be how I just explained it.
