What is the FD Calculator?

You simply enter the principal amount, the annual interest rate, and the investment tenure, and the calculator returns the maturity value using simple interest or compound interest (annual or quarterly). It eliminates manual calculations and lets you compare scenarios in seconds, making it an essential tool for anyone planning their savings.

How to Use

  1. 1.Enter the principal investment amount using the slider or the input box.
  2. 2.Set the annual rate of interest offered by your bank.
  3. 3.Choose the time period in years, months, or days.
  4. 4.Select the interest type: Simple Interest, Compound Annually, or Compound Quarterly.
  5. 5.The calculator instantly displays Total Investment, Interest Earned, and Maturity Amount.

Formula Used

Compound Interest: A = P × (1 + r/n)^(n×t)
Simple Interest: A = P + (P × R × T / 100)
Interest Earned = A − P

Where P = Principal amount, r = annual interest rate (decimal), n = compounding frequency per year (4 for quarterly, 1 for annual), and t = tenure in years. For example, ₹1,00,000 at 7.5% for 3 years with quarterly compounding gives A ≈ ₹1,25,023 and Interest ≈ ₹25,023.

Frequently Asked Questions

What is a Fixed Deposit (FD)?

A Fixed Deposit is a financial instrument offered by banks and NBFCs where you invest a lump sum amount for a fixed tenure at a predetermined interest rate. The returns are guaranteed and independent of market fluctuations, making FD one of the safest investment options in India.

How is FD interest calculated?

For compound interest FDs, the formula is A = P × (1 + r/n)^(n×t). Most Indian banks compound FD interest quarterly. For simple interest FDs, Interest = P × R × T / 100. The maturity amount is the sum of principal and earned interest.

Is FD interest taxable in India?

Yes, FD interest is fully taxable as per your income tax slab. TDS is deducted by the bank if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). You must declare FD interest in your ITR even if TDS was not deducted.

What is the best FD tenure for maximum returns?

The best FD tenure depends on your liquidity needs and the bank's rate slab. In India, tenures of 1–3 years often offer the highest rates. Senior citizens typically get an additional 0.25–0.50% over regular rates. Always compare current FD rates before investing.
