1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes wealth to grow faster than simple interest, especially over long periods.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( A \) — Future value of investment
\( P \) — Principal investment amount
\( r \) — Annual interest rate (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested for (years)

Explanation: More frequent compounding leads to higher returns. The formula accounts for both the principal growth and the compounding effect.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for retirement planning, savings strategies, and recognizing the power of long-term investing. Small differences in rates or compounding frequency can lead to significant differences over decades.

4. Using the Calculator

Tips: Enter principal in dollars, annual rate as percentage (e.g., 5 for 5%), select compounding frequency, and investment period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on principal plus accumulated interest.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (e.g., monthly vs. annually) results in higher returns due to the "interest on interest" effect occurring more often.

Q3: What's a realistic high-interest rate for savings?
A: As of 2023, high-yield savings accounts typically offer 3-5% APY, though rates vary with economic conditions.

Q4: Should I prioritize higher rate or more frequent compounding?
A: Generally, a higher rate has more impact than compounding frequency. But ideally you want both a high rate and frequent compounding.

Q5: How can I maximize compound interest benefits?
A: Start early, reinvest all earnings, choose accounts with highest rates and most frequent compounding, and add to your principal regularly.
