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 causes wealth to grow faster than simple interest because you earn interest on interest.

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 the 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: The more frequently interest is compounded, the greater the return. Monthly compounding (n=12) yields better returns than annual compounding (n=1).

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for long-term financial planning. Even small differences in interest rates or compounding frequency can significantly impact your savings over time.

4. Using the Calculator

Tips: Enter the principal amount, annual interest rate (as a percentage), time period in years, and how many times per year interest is compounded. For monthly compounding, enter 12.

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 the principal plus accumulated interest.

Q2: How often do high-yield savings accounts compound?
A: Most compound interest daily or monthly, which is better for savers than annual compounding.

Q3: Does compounding frequency really make a big difference?
A: Yes, especially over long periods. Daily compounding yields slightly more than monthly compounding.

Q4: What's a realistic interest rate for high-yield savings?
A: As of 2023, top high-yield savings accounts offer 4-5% APY, but rates fluctuate with the market.

Q5: Should I include taxes in my calculations?
A: Interest earned is taxable income, so for precise planning you may want to account for taxes.
