Understanding Your Savings Dividend Rate

If you save with a credit union, you earn dividends rather than interest. While they function similarly, dividends represent your share of the credit union's profits. This calculator helps you determine how much your initial deposit will grow based on the credit union's declared dividend rate and compounding frequency.

Dividend Rate vs. APY

It is important to distinguish between the nominal Dividend Rate and the Annual Percentage Yield (APY). The Dividend Rate is the simple percentage used to calculate earnings, whereas the APY reflects the total amount earned in a year including the effect of compounding. Because dividends compound (you earn dividends on your dividends), the APY is always slightly higher than the Dividend Rate.

How the Calculation Works

The growth of your savings is calculated using the compound interest formula:

A = P(1 + r/n)^nt

• P: The initial amount you deposited.
• r: The annual dividend rate (as a decimal).
• n: The number of times the dividend is compounded per year.
• t: The number of years the money is left in the account.

Real-World Example

Imagine you deposit $10,000 into a high-yield share account with a 4.50% Dividend Rate that compounds monthly. If you leave that money untouched for 3 years:

• Monthly Compounding: Your money earns a small portion of the 4.50% every month, which is then added to the balance for next month's calculation.
• 3-Year Result: You would end up with a balance of approximately $11,442.48.
• Earnings: You earned $1,442.48 in total dividends just by letting your savings sit.
• APY: Your effective annual yield would be 4.59%.

The Power of Compounding Frequency

The more frequently your credit union compounds dividends, the faster your savings grow. While the difference between monthly and daily compounding might seem small on a $1,000 balance, it becomes significant over many years or with larger share balances. Always check if your financial institution compounds daily, monthly, or quarterly to get an accurate projection of your future wealth.
