What Is a Fixed Deposit (FD)?

A Fixed Deposit, commonly called an FD, is a financial product where you deposit a lump-sum amount with a bank or eligible financial institution for a predetermined period at an agreed interest rate.

Depending on the institution and deposit product, FD tenures may range from a few days to several years.

The applicable FD interest rate generally depends on factors such as the financial institution, deposit tenure, deposit amount, customer category, and prevailing interest-rate environment.

At maturity, you receive the deposited principal along with applicable interest, subject to the terms of the fixed deposit.

Some FDs allow interest to accumulate and compound until maturity, while others provide periodic interest payouts.

What Is an FD Calculator?

An FD calculator is an online financial tool that helps estimate the interest earned and maturity amount of a fixed deposit.

Instead of manually calculating compound interest across different tenures and compounding frequencies, you can enter your deposit amount, FD interest rate, investment duration, and compounding frequency to estimate the potential outcome.

The InXits fixed deposit calculator can help you estimate:

  • Initial deposit amount
  • Total interest earned
  • FD maturity amount
  • Potential returns for different tenures
  • Impact of different FD rates
  • Impact of compounding frequency
  • Periodic interest income, where applicable

You can change the inputs to compare multiple fixed deposit scenarios before deciding where and for how long to invest.

How Does the FD Calculator Work?

The FD interest calculator uses the deposit amount, annual interest rate, investment tenure, and compounding frequency to estimate your maturity value.

For a cumulative FD, interest earned during each compounding period is added to the investment.

Future interest is then calculated on the increased balance, allowing the investment to benefit from compounding.

For example, suppose you invest ₹1,00,000 in a cumulative FD for 5 years at an assumed annual interest rate of 7% with quarterly compounding.

The FD calculator applies the selected interest rate and compounding frequency to estimate the interest earned and maturity amount at the end of the tenure.

You can then change the FD rate, tenure, or deposit amount to compare different scenarios.

Formula Used to Calculate FD Maturity Amount

For fixed deposits where interest is compounded periodically, the maturity amount can be estimated using the compound interest formula:

A = P × (1 + r/n)^(n × t)

Where:

A = FD maturity amount

  • P = Principal amount deposited
  • r = Annual interest rate expressed as a decimal
  • n = Number of times interest is compounded per year
  • t = Investment tenure in years

The total interest earned can be calculated as:

Interest Earned = Maturity Amount − Principal Amount

Actual maturity values may vary depending on the financial institution’s interest calculation method, compounding rules, payout option, tenure conventions, premature withdrawal, and applicable taxes.

What Does the FD Calculator Show?
  • Principal Amount
    The initial amount deposited in the fixed deposit
  • Total Interest Earned
    The estimated interest generated by your FD during the selected tenure
  • FD Maturity Amount
    The estimated total value of your fixed deposit at the end of the investment period
  • Effective Growth of Your Deposit
    See how your principal may grow over the selected tenure based on the entered FD interest rate and compounding frequency.
  • Year-by-Year FD Growth
    Understand how the value of a cumulative FD may increase over time as interest is added to the deposit
  • Periodic Interest Payout
    For non-cumulative deposits, estimate the interest income that may be paid monthly, quarterly, half-yearly, or annually
How to Use the InXits FD Calculator

Using the FD calculator online is simple.

  • Enter your Deposit Amount — the lump-sum amount you want to place in the fixed deposit.
  • Enter the FD Interest Rate — the annual interest rate applicable to your deposit.
  • Select the FD Tenure — choose the number of months or years for which the deposit will remain invested.
  • Choose the Compounding Frequency — monthly, quarterly, half-yearly, or annually, depending on the fixed deposit you want to calculate.

The FD maturity calculator will estimate the interest earned and total maturity amount.

Change the inputs to compare different FD rates, tenures, and compounding frequencies.

FD Calculator with TDS
  • Interest earned from fixed deposits may be subject to taxation and Tax Deducted at Source (TDS) under applicable income-tax rules.
  • An FD calculator with TDS can help illustrate the difference between gross interest and estimated interest after entering an applicable TDS assumption.
  • However, TDS is not the same as your final tax liability.
  • Your actual tax liability depends on factors including your total taxable income, tax regime, applicable income-tax slab, exemptions, deductions, and current tax regulations.

Why Use an FD Calculator Before Investing?

Fixed deposit returns may appear simple to calculate, but comparing deposits can become difficult when interest rates, tenures, and compounding frequencies differ. Two fixed deposits offering the same headline FD interest rate may generate different maturity amounts if the interest compounding or payout structures are different.

The FD calculator helps you evaluate the relationship between your deposit, the interest earned, and your final maturity amount. By entering different scenarios and testing multiple combinations, you can understand how changes in the FD rate, investment period, and compounding frequency may affect your final maturity value. This data-driven approach eliminates guesswork and helps you make informed investment decisions.

Deposit Amount + Interest Earned = FD Maturity Amount

Cumulative FD Calculator

A cumulative fixed deposit reinvests the interest earned into the deposit instead of paying it periodically.
The accumulated interest is added to the deposit balance, and future interest is calculated on the increased amount.
This creates the effect of compound interest.
A cumulative FD calculator helps estimate how much your investment may grow when interest remains invested until maturity.
Cumulative FDs may be considered by investors who do not need regular interest income and want the interest to compound over the selected tenure.

Example: ₹1,00,000 at 7% p.a. for 5 years with Quarterly Compounding

FD Calculator for 5 Years

A 5-year fixed deposit is a commonly searched tenure for medium-term savings goals.
You can use the FD calculator for 5 years to compare how different interest rates may affect your final maturity amount.
Enter the same investment amount and test multiple FD rates to understand the difference in interest earned over the full investment period.
Certain eligible 5-year fixed deposits may qualify as tax-saving fixed deposits, subject to applicable tax laws and product conditions.

FD Calculator with TDS

Interest earned from fixed deposits may be subject to taxation and Tax Deducted at Source (TDS) under applicable income-tax rules.
An FD calculator with TDS can help illustrate the difference between gross interest and estimated interest after entering an applicable TDS assumption.
However, TDS is not the same as your final tax liability.
Your actual tax liability depends on factors including your total taxable income, tax regime, applicable income-tax slab, exemptions, deductions, and current tax regulations.

FD Calculator for Monthly Interest

Some investors use fixed deposits to generate periodic cash flow.
In a monthly interest payout FD, interest is paid at regular monthly intervals instead of being accumulated until maturity.
The FD calculator monthly interest option can help estimate the periodic income generated by your deposit based on the principal amount and applicable interest rate.
For example, you can estimate the potential monthly interest income from a ₹5 lakh, ₹10 lakh, or ₹25 lakh fixed deposit.
Actual monthly payout calculations may vary because financial institutions may apply specific payout and discounting conventions.

FD Calculator with Quarterly Compounding

Quarterly compounding means interest is calculated and added to the cumulative deposit balance four times during a year.
Once interest is added to the principal, future interest calculations are based on the increased deposit amount.
Use the FD calculator quarterly compounding option to estimate how quarterly compounding affects the interest earned and maturity value of your deposit.

Senior Citizen FD Calculator

Banks and financial institutions may offer additional interest rates on eligible fixed deposits held by senior citizens.

A senior citizen FD calculator helps estimate the maturity amount and interest earned using the applicable senior citizen interest rate.

Enter the deposit amount, tenure, and the actual interest rate offered by the institution to calculate the estimated maturity value.

Eligibility criteria and additional interest rates may differ across institutions and deposit products.

Tax-Saving FD Calculator

A tax-saving fixed deposit is a specific fixed deposit product with a lock-in period and tax treatment governed by applicable tax laws.

Use the tax-saving FD calculator to estimate the interest earned and maturity value of an eligible deposit over its tenure.

Tax benefits, investment limits, lock-in requirements, and taxation of interest are subject to prevailing tax rules.

An FD calculator estimates investment growth and should not be treated as a tax-benefit calculator unless the applicable tax assumptions are specifically included.

How Does Compounding Frequency Affect FD Returns?

Compounding frequency determines how often accumulated interest is added to the deposit balance.

Common compounding frequencies include:

  • Monthly compounding
  • Quarterly compounding
  • Half-yearly compounding
  • Annual compounding

When the stated annual interest rate and all other conditions remain the same, more frequent compounding can result in a higher maturity amount because interest begins earning additional interest sooner.

However, actual FD returns depend on the calculation method and deposit terms used by the financial institution.

FD Interest Rates and Maturity Amount

FD interest rates directly affect the interest earned and maturity amount of your fixed deposit.

Even a relatively small difference in the interest rate can affect long-term returns, particularly for larger deposits or longer investment periods.

Before choosing a fixed deposit, consider comparing:

  • Applicable FD interest rate
  • Investment tenure
  • Compounding frequency
  • Cumulative or payout option
  • Premature withdrawal rules
  • Penalties
  • Senior citizen benefits, if applicable
  • Tax implications
  • Deposit insurance limits and issuer risk

The highest FD rate is not automatically the most suitable deposit for every investor.

Factors That Affect Your FD Returns

  • Deposit Amount
    A larger principal amount generates more interest when the rate and tenure remain unchanged.
  • FD Interest Rate
    A higher interest rate generally results in higher interest earnings, subject to the terms of the deposit.
  • Investment Tenure
    Longer tenures provide more time for interest accumulation and potential compounding.
  • Compounding Frequency
    The frequency at which interest is added to the cumulative deposit balance can affect the maturity amount.
  • Interest Payout Option
    Cumulative and non-cumulative fixed deposits handle interest differently and serve different cash-flow requirements.
  • Premature Withdrawal
    Closing an FD before maturity may result in reduced interest, penalties, or both, depending on the institution’s terms.
  • Taxation
    Tax and TDS can affect the effective post-tax return earned from a fixed deposit.
