1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows savings to grow at an accelerating rate over time, making it a powerful tool for long-term wealth accumulation.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( FV \) — Future Value (currency)
\( P \) — Principal amount (currency)
\( r \) — Annual interest rate (decimal)
\( n \) — Compounding periods per year (unitless)
\( t \) — Time in years (years)

Explanation: The formula calculates how much an investment will grow over time when interest is compounded at regular intervals.

3. Importance of Compound Interest

Details: Compound interest is fundamental to long-term financial planning and wealth building. It demonstrates how regular savings can grow significantly over time, especially with higher interest rates and more frequent compounding.

4. Using the Calculator

Tips: Enter the principal amount in dollars, interest rate as a decimal (e.g., 0.05 for 5%), number of compounding periods per year, and time 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 both the principal and accumulated interest.

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

Q3: What is a good interest rate for savings?
A: Interest rates vary by economic conditions and financial institutions. High-yield savings accounts typically offer better rates than traditional savings accounts.

Q4: Can compound interest work against me?
A: Yes, when borrowing money, compound interest can significantly increase the amount you owe over time, especially with high-interest debt.

Q5: How can I maximize compound interest benefits?
A: Start saving early, contribute regularly, choose accounts with higher interest rates, and allow your investments to compound over long periods.
