What Is a Fixed Deposit (FD) Calculator?
A Fixed Deposit calculator helps you estimate the maturity value of your FD investment before you commit your money to a bank or financial institution. By entering the principal amount, annual interest rate, tenure, and compounding frequency, you can instantly see how much your deposit will grow over time.
How Does FD Interest Work?
Fixed deposits earn compound interest, meaning the interest you earn is periodically added back to your principal, and future interest is calculated on this larger amount. The formula used is A = P × (1 + r/n)n×t, where P is the principal, r is the annual interest rate as a decimal, n is the number of times interest compounds per year, and t is the tenure in years. Banks in India typically offer quarterly compounding, but some may compound monthly, half-yearly, or annually.
Why Use This Calculator?
Comparing FD schemes from different banks can be confusing when they use different compounding frequencies. This calculator lets you switch between monthly, quarterly, half-yearly, and annual compounding so you can make a fair comparison. It also accepts tenure in both years and months, making it easy to model short-term or odd-period deposits. All calculations happen instantly in your browser with no data sent to any server, so your financial details remain completely private. Use it to plan your savings, compare bank offers, or simply understand how compound interest grows your wealth over time.

Frequently Asked Questions
What is a Fixed Deposit?
A Fixed Deposit (FD) is a financial instrument offered by banks and NBFCs where you deposit a lump sum for a fixed tenure at a predetermined interest rate. It is one of the safest investment options in India, offering guaranteed returns with no market risk.
How is FD interest calculated?
FD interest is calculated using the compound interest formula: A = P × (1 + r/n)^(n×t), where P is the principal, r is the annual interest rate, n is the compounding frequency per year, and t is the tenure in years. Most Indian banks use quarterly compounding by default.
What is the best compounding frequency for FD?
A higher compounding frequency yields more returns. Monthly compounding gives slightly better returns than quarterly, which in turn is better than half-yearly or annual compounding. However, the difference is often marginal for typical FD amounts and tenures.
Is FD interest taxable?
Yes, FD interest is fully taxable as per your income tax slab. Banks deduct TDS at 10% if interest exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). You can submit Form 15G/15H to avoid TDS if your total income is below the taxable limit.
