1. What is CD Account Growth?

A Certificate of Deposit (CD) is a savings product that earns interest on a lump sum for a fixed period. CD growth represents the total value accumulated through compound interest over the investment period, providing predictable returns with FDIC insurance protection.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ FV = P \times (1 + \frac{r}{n})^{n \times t} \]

Where:

$ FV $ — Future Value of investment
$ P $ — Principal amount (initial deposit)
$ r $ — Annual interest rate (as decimal)
$ n $ — Number of compounding periods per year
$ t $ — Time in years

Explanation: The formula calculates how your initial investment grows through compound interest, where interest earned is added to principal and earns additional interest in subsequent periods.

3. Importance of CD Investment

Details: CDs offer guaranteed returns, capital preservation, and predictable income. They are ideal for short-to-medium term savings goals, emergency funds, and conservative investment strategies where principal protection is prioritized.

4. Using the Calculator

Tips: Enter principal in USD, annual interest rate as percentage, select compounding frequency, and investment period in years. All values must be positive numbers with principal > 0 and time > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between simple and compound interest?
A: Simple interest is calculated only on principal, while compound interest calculates interest on both principal and accumulated interest, leading to exponential growth.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (daily vs annually) results in higher returns due to interest being calculated and added to principal more often.

Q3: Are CD earnings taxable?
A: Yes, interest earned on CDs is taxable as ordinary income in the year it is credited to your account, unless held in tax-advantaged accounts.

Q4: What happens if I withdraw CD funds early?
A: Early withdrawal typically incurs penalties, often calculated as a portion of interest earned, which can reduce or eliminate your returns.

Q5: Are CDs FDIC insured?
A: Yes, CDs offered by FDIC-member banks are insured up to $250,000 per depositor, per insured bank, for each account ownership category.
