1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account where interest is earned on both the initial principal and the accumulated interest from previous periods. This is particularly important for long-term savings planning in the Philippines.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + R / n)^{n \times T} \]

Where:

\( P \) — Principal amount (initial investment in PHP)
\( R \) — Annual interest rate (in decimal form)
\( n \) — Compounding frequency per year
\( T \) — Time period in years
\( A \) — Maturity amount (final amount in PHP)

Explanation: The formula accounts for how frequently interest is compounded, which significantly affects the final amount over time.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest is crucial for financial planning, retirement savings, and maximizing returns on investments in Philippine banks and financial institutions.

4. Using the Calculator

Tips: Enter principal amount in PHP, annual interest rate as a percentage, select compounding frequency, and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is 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 my savings?
A: More frequent compounding (daily vs annually) results in higher returns due to interest being calculated and added to the principal more often.

Q3: Are Philippine banks required to compound interest?
A: Compounding practices vary by bank and account type in the Philippines. Always check the specific terms of your savings account.

Q4: Is compound interest taxable in the Philippines?
A: Yes, interest income from bank deposits in the Philippines is subject to 20% final withholding tax.

Q5: What's the best compounding frequency for savings?
A: Generally, more frequent compounding (daily or monthly) yields better returns, but you should compare overall annual percentage yields (APY).
