If you find yourself trying to remember what does apy mean think APY amount paid to you. No for 10k it would be 200 a year not a month since Annual Percentage Yield the total money you earn in interest over a year expressed as a percentage of your total balance. In this formula r is the stated annual interest rate and n is the number of compounding periods each.
Dividend yield is the percentage a company pays out annually in dividends per dollar you invest.
In non-banker-jargon APY stands for the amount an account pays to you. APY 1 rnn n 1. Raise the result to the number of compounding periods in a year and then subtract 1 to calculate the APY in decimal format. Yields for a current year can be estimated using the previous years dividend or by multiplying the latest quarterly dividend by 4 then dividing by the current share price.
