FD Calculator - Fixed Deposit Calculator Online

Planning your savings is now simpler with an FD calculator that helps you see clearly how your money grows over time. Whether you are investing for a few months or several years, it shows the exact returns you will get, so there are no surprises. In this blog, you will learn about fixed deposits and how does an FD calculator work.

What is a Fixed Deposit?

A Fixed Deposit (FD) is a safe and popular savings option offered by banks and NBFCs in India. You invest a lump sum for a fixed period, and it earns interest at a pre-decided rate. The interest is higher than a regular savings account, which makes it ideal for risk-free wealth growth. You can choose tenures ranging from 7 days to 10 years. FD returns are guaranteed, and the principal stays safe. Premature withdrawal is allowed but may attract a small penalty.

Types of Fixed Deposits in India

Fixed Deposits (FDs) come in different forms to suit different financial goals. The details below include the different types of fixed deposits in India:

1. Regular Fixed Deposit: This is the most common type. You invest a lump sum for a fixed tenure (7 days to 10 years) and earn guaranteed returns at a fixed interest rate. Interest is paid periodically or at maturity.
2. Tax-Saving Fixed Deposit: This FD has a lock-in period of 5 years and offers tax benefits under Section 80C of the Income Tax Act (up to Rs. 1.5 lakh/year). However, premature withdrawal and loans are not allowed. It is Ideal for Salaried individuals looking for tax benefits.
3. Senior Citizen Fixed Deposit: Specially designed for individuals above 60 years of age, these FDs offer higher interest rates (usually 0.25%–0.75% extra) than regular FDs. HDFC Senior Citizen Care FD offers up to 7.75% interest (as of 2025).
4. Cumulative FD: In a cumulative FD, interest gets compounded regularly and is paid together with the principal when the deposit matures. It is ideal for long-term investors looking to grow wealth steadily.
5. Non-Cumulative FD: This FD pays interest monthly, quarterly, or yearly. It is suitable for those who want a regular income, like retirees or homemakers.
6. Flexi or Sweep-in FD: This is linked to your savings account. Any amount above a set limit is automatically transferred into an FD to earn higher interest while keeping funds liquid.

What is an FD Calculator?

An FD Calculator is an easy online tool that helps you know how much return you will earn from a Fixed Deposit. Just enter the deposit amount, interest rate, and tenure, and it instantly shows your total maturity value and interest earned. It removes guesswork, helps in comparing plans, and makes financial planning faster and clearer. Whether you choose monthly, quarterly, or yearly payouts, the calculator adjusts accordingly. Major banks like SBI, HDFC Bank, and Axis Bank offer free FD calculators on their websites. It is perfect for salaried individuals, senior citizens, and investors who want to grow savings confidently without complicated math.

How Does a Fixed Deposit Calculator Work?

An FD Calculator works by using a simple formula to calculate the total maturity amount and interest you will earn on your fixed deposit. You only need to enter these three basic details, which are as follows:

• Deposit Amount (how much you want to invest)
• Interest Rate (offered by the bank/NBFC)
• Tenure (like how long you want to keep the money invested)

Once you enter these values, the calculator shows you:

• Total Maturity Amount (principal + interest)
• Total Interest Earned

For cumulative FDs, the calculator uses compound interest formulas. For non-cumulative FDs, it calculates interest payouts monthly, quarterly, or annually based on your choice. These tools help you compare different FD plans, choose the best tenure, and plan your savings confidently, without needing to do any manual calculations. Whether you are saving for short-term goals or long-term wealth, an FD calculator ensures your financial planning is accurate, fast, and stress-free

Factors That Affect FD Returns

When you invest in a Fixed Deposit (FD), you expect safe and stable returns. But your final maturity amount is not only about how much you invest, it also depends on several important factors. Knowing these will help you make smarter decisions and choose the best FD plan.

Deposit Amount

The amount you invest in an FD directly affects your returns. Some banks offer slightly higher interest rates for higher investment slabs (above Rs. 1 crore or Rs. 2 crore). However, for most regular investors, the return is proportional to the amount invested.

Tenure (Investment Duration)

FDs with longer tenures usually offer higher interest rates. For example, a 5-year FD may earn more than a 1-year FD. But this is not always linear, as some short-to-medium-term FDs (like 444 days or 2 years) also offer special rates, as seen in schemes from Indian Bank and SBI.

Interest Rate Offered

This is the biggest factor. Interest rates vary by:

• Bank/NBFC (SBI, HDFC, Bajaj Finance)
• Market conditions (influenced by RBI’s repo rate)
• Your profile (senior citizens often get 0.25%–0.75% more)

As of June 2025, general FD rates range from 6% to 7.25%, while senior citizens can earn up to 7.75% or more.

Type of FD: Cumulative vs Non-Cumulative

• Cumulative FDs: Interest is compounded and paid at maturity. Ideal for wealth growth.
• Non-Cumulative FDs: Interest is paid monthly, quarterly, or annually. Suitable for regular income seekers.

Returns differ based on compounding frequency. Cumulative FDs usually yield higher overall returns.

Customer Category (Senior Citizens, Super Seniors)

Banks give extra interest to:

• Senior Citizens (60+ years): Usually 0.50% extra
• Super Senior Citizens (80+ years): Some banks like SBI offer an additional 10 bps

This bonus directly increases the FD returns for older investors.

Bank or Financial Institution

Returns also vary from one institution to another:

• Public banks (like SBI, PNB): Lower but safer
• Private banks (like HDFC, ICICI): Moderate returns
• Small Finance Banks & NBFCs (like Jana, Shriram, Bajaj Finance): Higher returns but slightly more risk

Always check if the institution is covered under DICGC insurance (up to Rs. 5 lakh per depositor).

RBI Policies & Economic Conditions

The RBI’s monetary policy directly impacts FD interest rates. When the RBI cuts the repo rate, banks usually reduce FD rates. So, economic conditions can change your FD returns even before you invest.
