1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or deposit where interest is earned on both the initial principal and the accumulated interest from previous periods. This is the standard method used by SBI and other banks for fixed deposits and savings accounts.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

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

Explanation: The formula accounts for the effect of compounding, where interest is added to the principal at regular intervals, leading to exponential growth of your investment.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest helps investors make informed decisions about savings and investments. It demonstrates how small, regular investments can grow significantly over time due to the power of compounding.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How often does SBI compound interest on deposits?
A: SBI typically compounds interest quarterly for most fixed deposits, but the frequency may vary depending on the specific deposit scheme.

Q2: 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.

Q3: Are there taxes on interest earned?
A: Yes, interest earned on deposits is taxable as per Indian income tax laws. TDS may be deducted if interest exceeds certain thresholds.

Q4: Can I calculate interest for partial years?
A: Yes, you can enter decimal values for time (e.g., 2.5 years for 2 years and 6 months).

Q5: Does this calculator account for changing interest rates?
A: No, this calculator assumes a constant interest rate throughout the investment period. For varying rates, separate calculations would be needed for each period.
