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.
How to Compute Maturity
Input deposit figures to verify banking return schedules.
Deposit Principal
Input the starting lump-sum capital you will lock in the bank deposit.
Rate of Interest
Specify the annual interest rate guaranteed by the financial institution.
Lock-in Tenure
Select the duration of the deposit in years or months. FDs typically compound quarterly.
The Fixed Deposit Formula
The compound interest calculation is based on the compounding frequency:
A = P × (1 + r/n)n × t
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.
