1. What is a Quarterly Interest Calculator on FD?

Definition: This calculator computes the interest earned on a fixed deposit (FD) for one quarter based on the principal amount and annual interest rate.

Purpose: It helps investors understand how much interest they will earn every quarter on their fixed deposit investments.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ I = P \times \left(\frac{r}{4}\right) \]

Where:

\( I \) — Quarterly interest (USD)
\( P \) — Principal amount (USD)
\( r \) — Annual interest rate (decimal)

Explanation: The annual interest rate is divided by 4 to get the quarterly rate, then multiplied by the principal amount.

5. Frequently Asked Questions (FAQ)

Q1: Is the quarterly interest compounded?
A: This calculator shows simple quarterly interest. For compound interest, the calculation would be different.

Q2: Why divide by 4?
A: There are 4 quarters in a year, so we divide the annual rate by 4 to get the quarterly rate.

Q3: How does this differ from monthly interest?
A: Monthly interest would divide the annual rate by 12 instead of 4.

Q4: Can I use this for any currency?
A: Yes, though the calculator shows USD, you can use any currency as long as you're consistent.

Q5: What if my bank pays interest semi-annually?
A: You would need to divide the annual rate by 2 instead of 4 for semi-annual calculations.
