Understanding Fixed Deposits

A Fixed Deposit (FD), also known as a Term Deposit or Time Deposit, is a financial instrument offered by banks and non-banking financial institutions. When you open an FD, you deposit a lump sum amount for a predetermined period at a fixed interest rate.

Unlike a regular savings account where you can withdraw money anytime, an FD locks your money for the chosen tenure. In return, you receive a higher interest rate than savings accounts, making it an attractive option for risk-averse investors seeking guaranteed returns. Learn more about the key differences between FD and Savings Account.

According to the Investopedia definition, time deposits are among the safest investment vehicles, backed by government deposit insurance in most countries.

Types of Fixed Deposits

Regular Fixed Deposit

Standard FD with fixed tenure and interest rate. Interest can be paid monthly, quarterly, or at maturity.

Tax-Saving Fixed Deposit

Special FDs with tax benefits under specific government schemes. Usually has a lock-in period of 5 years.

Senior Citizen Fixed Deposit

FDs offering 0.25% to 0.75% higher interest rates for customers above 60 years of age.

Cumulative Fixed Deposit

Interest is compounded and paid at maturity along with the principal, maximizing returns.

Non-Cumulative Fixed Deposit

Interest is paid out periodically (monthly, quarterly, annually) rather than at maturity.

Flexi Fixed Deposit

Linked to savings account, allowing partial withdrawals while earning FD interest rates.

How is FD Interest Calculated?

Fixed Deposit interest is calculated using the compound interest formula:

A = P × (1 + r/n)n×t

For example, if you deposit $10,000 at 6% annual interest for 3 years with quarterly compounding, your maturity amount would be approximately $11,956. Calculate your specific returns with our FD Calculator.
