most every research site already gives you the dividend % anyway. You'll see that. Not sure I'd take any dividend as a lock right now as I keep hearing companies reducing dividends... and yes, some are increasing. Just be sure you are buying the stock because of its quality and future. You purchase because of a dividend... your principle could slide right down into a black hole. The market is a fun place, but a lot of sharks in the water with big teeth.
A bit of friendly advice. If you are so poor at math that you cannot calculate the % dividend, you may perhaps be better off NOT investing in stocks at all.
And oh, by the way genetuck you forgot to tell him to multiply the result ( Dividend/price) by 100 to get the % in a non-decimal form.
