1. What is Compound Interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It's often called "interest on interest" and makes a sum grow at a faster rate than simple 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 formula calculates how much your investment will grow when interest is compounded at regular intervals.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning. It demonstrates how investments grow over time and helps compare different investment options.

4. Using the Calculator

Tips: Enter principal in euros, annual interest rate as a percentage (e.g., 5 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 the principal plus any accumulated interest.

Q2: How does compounding frequency affect results?
A: More frequent compounding leads to higher returns. Daily compounding yields more than monthly, which yields more than yearly.

Q3: What's a typical compounding frequency?
A: Savings accounts often compound daily, while bonds typically compound semi-annually. Check your financial product's terms.

Q4: Can this calculator be used for loans?
A: Yes, it works for both investments and loans, though loans may have additional fees not accounted for here.

Q5: How accurate is this calculator?
A: It provides theoretical results assuming constant rate and no additional deposits/withdrawals. Actual results may vary.
