FD Calculator

A fixed deposit (FD) is a safe way to grow your savings, and an FD calculator helps you estimate your returns by calculating the maturity amount and interest earned. This tool makes it easy to plan your investments, whether you’re saving for a goal or building wealth. Our mobile-friendly calculator below, inspired by Groww, delivers accurate results for any interest rate and tenure. Try it now to see how much your FD will grow, then read on to learn how it works and why it’s essential for your financial planning.

What is an FD Calculator?

An FD calculator is an online tool that estimates the growth of your fixed deposit by calculating the maturity amount and interest earned. It uses your deposit amount, interest rate, tenure, and compounding frequency to provide accurate results. For example, investing ₹1,00,000 at 8.25% for 5 years with quarterly compounding yields a maturity amount of ₹1,50,029.66.

How Does an FD Calculator Work?

Using our calculator is simple and helps you plan your savings:

  1. Enter the Deposit Amount (e.g., ₹1,00,000).
  2. Input the Interest Rate (e.g., 8.25%).
  3. Specify the Investment Tenure in years (e.g., 5).
  4. Select the Compounding Frequency (e.g., Quarterly).
  5. Click Calculate to see your maturity amount and interest earned.

The calculator uses the compound interest formula:

  • Maturity Amount: P * (1 + r/n)^(n*t), where P is the deposit amount, r is the annual interest rate, n is the compounding periods per year, and t is the tenure in years.
  • Total Interest Earned: Maturity Amount - Deposit Amount.

Benefits of Using an FD Calculator

An FD calculator offers several advantages for investors:

  • Quick Results: Instantly see how much your FD will grow.
  • Flexible Inputs: Supports any positive interest rate and various tenures.

Factors Affecting Your Fixed Deposit Returns

Your FD returns depend on key factors, as shown below:
