How to use this tool

What is a Fixed Deposit?

A Fixed Deposit (FD) is a financial instrument provided by banks and NBFCs where you deposit a lump sum for a fixed tenure at a predetermined interest rate. It offers guaranteed, low-risk returns.

Step-by-Step Blueprint

How to Compute Maturity

Input deposit figures to verify banking return schedules.

1

Deposit Principal

Input the starting lump-sum capital you will lock in the bank deposit.

2

Rate of Interest

Specify the annual interest rate guaranteed by the financial institution.

3

Lock-in Tenure

Select the duration of the deposit in years or months. FDs typically compound quarterly.


Mathematical Foundation

The Fixed Deposit Formula

The compound interest calculation is based on the compounding frequency:

A = P × (1 + r/n)n × t

A: Maturity Amount (Principal + Interest)
P: Principal Deposit Amount
r: Annual Interest Rate (decimal)
n: Number of compounding periods per year
t: Tenure in years

Common Inquiries

Frequently Asked Questions

Standard rules regarding fixed interest vehicles.

How often does interest compound in FDs?

Standard retail banking FDs compound interest quarterly (4 times per year). Some institutions allow monthly payout compounding, or simple interest for shorter horizons (less than 6 months).

Are FD returns taxable?

Yes. In most tax jurisdictions, the interest earned on Fixed Deposits is considered taxable income. Some bank deposits offer tax-saving deductions with a mandatory 5-year lock-in.
