How to calculate the money you will receive from dividends?

Your dividend is .10, meaning 10 cents.  First you have to determine if it is paid quarterly (meaning four times a year).  Most are paid that often.  Assuming your 10 cents is paid out quarterly, you will receive a total of 40 cents in dividends per year - per share.  Your stock is valued (currently) at $5.50, so 40 cents divided by $5.50 equals 7.2% yield (not .72%).  Since you own 10 shares, you will earn 40 cents x 10 = $4.00 on those 10 shares each year.  As the price of your stock goes up the yield essentially goes down, since 40 cents is less of a percentage of a higher price; if the price of the stock goes down, your percentage yield goes UP, since 40 cents is a higher percentage of the stock price.

This is a very good yield!  

Most financial websites will tell you when the stock goes Ex Dividend, meaning if you buy the shares after that date, you will NOT be eligible for the upcoming dividend payment.  If you sell after the Ex Dividend, but before the dividend payement however, you WILL receive dividend payments.
