What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a secure investment instrument offered by banks and Non-Banking Financial Companies (NBFCs) where investors deposit a lump sum amount for a fixed tenure and earn guaranteed returns at a predetermined interest rate.

Fixed Deposits are among the most popular low-risk investment options in India because they provide stable returns, capital safety, and flexible investment periods. FD investments are suitable for conservative investors seeking predictable income and financial security.

Unlike savings accounts, Fixed Deposits generally offer higher interest rates and allow investors to choose tenures ranging from a few days to several years.

How FD Calculator Works

An FD Calculator helps estimate the maturity amount and total interest earned on a Fixed Deposit investment.

The calculator estimates:

• maturity amount
• total interest earned
• yearly investment growth
• compound interest effect

based on:

• deposit amount
• annual interest rate
• investment tenure
• compounding frequency

The calculator provides instant and accurate projections to help investors compare FD options and plan savings efficiently.

Bank or NBFC Policies

Different financial institutions offer varying FD interest rates and schemes.

Taxation on FD Interest

Interest earned from Fixed Deposits is taxable according to the investor’s income tax slab.

TDS on FD Interest

Banks deduct Tax Deducted at Source (TDS) if FD interest exceeds the prescribed limit.

Taxable Interest

FD interest income must be declared while filing income tax returns.

Form 15G and Form 15H
