Use this calculator to estimate the potential earnings on a Hanscom Federal Credit Union Share Certificate (Certificate of Deposit). Enter your deposit amount, the desired term in months, and the current Annual Percentage Yield (APY) offered by HFCU to see your projected return at maturity.
Common HFCU terms range from 3 to 60 months.
Enter the APY percentage rate.

Maximizing Savings with Hanscom Federal Credit Union Share Certificates
For members of Hanscom Federal Credit Union (HFCU) looking for a secure way to grow their savings with guaranteed returns, Share Certificates—the credit union equivalent of bank Certificates of Deposit (CDs)—are an excellent option. Unlike standard savings accounts where rates can fluctuate, a Share Certificate locks in a specific dividend rate for a fixed period.
Using the calculator above helps HFCU members envision how different deposit amounts and term lengths can affect their financial goals at maturity.
Understanding the Calculator Inputs
To get an accurate estimate of your future earnings, it is important to understand the three key factors that determine your return:
Initial Deposit Amount: This is the lump sum of money you agree to deposit into the Share Certificate. HFCU typically has minimum deposit requirements (often starting around $500 or $1,000) to open a certificate. Generally, larger deposits may qualify for "jumbo" rates which offer higher yields.
CD Term (Months): This is the duration for which your money is locked in the account. HFCU offers a variety of terms, commonly ranging from short-term options like 3 or 6 months to longer-term commitments up to 60 months (5 years). Typically, longer terms reward you with higher dividend rates, though this is not always the case in unusual economic environments.
Annual Percentage Yield (APY %): The APY is the most critical number for comparing savings products. It represents the total amount of dividends you will earn on your deposit over one year, taking into account the effect of compounding interest. Because HFCU sets its rates based on market conditions, you must input the current APY offered for your desired term and deposit size.
Why Choose an HFCU Share Certificate?
Hanscom Federal Credit Union is a member-owned, not-for-profit financial cooperative. This structure often allows them to return profits to members in the form of higher dividends on savings products like Share Certificates compared to traditional big banks.
Furthermore, deposits at HFCU are federally insured by the National Credit Union Administration (NCUA) up to $250,000 per individual depositor, making Share Certificates a very low-risk investment vehicle.
Important Considerations: Early Withdrawal
When you open a Share Certificate, you are agreeing to leave the principal deposit untouched for the specified term. While life happens and you can withdraw funds early if necessary, HFCU, like nearly all financial institutions, charges an early withdrawal penalty. This penalty is usually calculated as a certain number of months' worth of dividends (e.g., 90 days or 180 days of dividends), which can significantly eat into your earnings or even reduce your principal balance. It is crucial to choose a term length that aligns with your financial timeline to avoid these penalties.
