How to Use the FD Calculator

A Fixed Deposit (FD) Calculator is an online financial tool that helps you estimate the maturity amount and interest earned on your fixed deposit investment based on the principal amount, interest rate, tenure, and compounding frequency.

Why Use an FD Calculator?

Fixed Deposits are one of the safest and most popular investment options, offering guaranteed returns over a fixed period. However, calculating the maturity value manually can be tricky due to compounding. The FD Calculator simplifies this by providing accurate results instantly.

FD Calculator FAQ

Q1: What formula does the FD Calculator use?
A: It uses the compound interest formula:M=P×(1+rn)n×tM=P×(1+nr​)n×t

Where:

• M = Maturity Amount
• P = Principal
• r = Annual Interest Rate (in decimal)
• n = Number of compounding periods per year
• t = Time (in years)

Q2: Can I use this calculator for Recurring Deposits (RD)?
A: No. This calculator is specifically for Fixed Deposits. Recurring Deposits require a different calculation method because deposits are made monthly.

---

Q3: What is the difference between simple and compound interest in FDs?
A: Simple interest gives a fixed return only on the principal, while compound interest reinvests earned interest, leading to higher returns. Most banks use compound interest.

---

Q4: How does compounding frequency affect my returns?
A: The more frequently your interest is compounded (monthly vs yearly), the higher your maturity amount, as interest gets added more often.

Q5: Is the FD Calculator 100% accurate?
A: Yes, it is accurate based on the inputs provided. However, actual bank policies, tax deductions (like TDS), and premature withdrawals may affect real returns.
