Understanding Your Certificate of Deposit (CD) Dividends
A Certificate of Deposit (CD) is a savings product offered by banks and credit unions that typically pays a fixed rate of interest, often called a dividend in the context of credit unions, for a specified term. Your CD dividend rate determines how much you will earn on your initial investment, known as the principal. The longer you keep your money in the CD, the more dividends you can accumulate.
Key Terms Explained:
Principal Amount: This is the initial sum of money you deposit into your CD. It's the base amount on which your dividends will be calculated.
Annual Dividend Rate: This is the percentage of your principal that you will earn in dividends over a one-year period. It's usually expressed as an annual percentage rate (APR).
Term (Months): This is the duration for which you agree to keep your money deposited in the CD. CDs typically come with various terms, such as 3 months, 6 months, 12 months, 24 months, or longer.
How Dividends are Calculated:
The calculation for the total dividends earned on your CD involves considering the principal, the annual dividend rate, and the term of the deposit. The formula used is generally:
Total Dividends = Principal * (Annual Dividend Rate / 100) * (Term in Months / 12)
This formula accounts for the fact that the dividend rate is annual, while the term is often expressed in months. By dividing the term in months by 12, we get the fraction of a year the CD is held, allowing for an accurate dividend calculation for periods less than a full year.
Example:
Let's say you invest $10,000 in a CD with an annual dividend rate of 4.5% for a term of 18 months. Using the calculator:
Principal: $10,000
Annual Dividend Rate: 4.5%
Term: 18 Months
The total dividends earned would be: $10,000 * (4.5 / 100) * (18 / 12) = $10,000 * 0.045 * 1.5 = $675.
After 18 months, you would have your initial principal of $10,000 plus $675 in dividends, for a total of $10,675.
