Summary
Fixed Deposit Calculator Online
A Fixed Deposit (FD) Calculator helps you estimate how much money you may receive when your fixed deposit reaches maturity. By entering your deposit amount, interest rate, and investment period, you can calculate the estimated interest earned and the final maturity amount.
This online FD Calculator supports both compound interest and simple interest calculations. You can also select a country and currency, making it useful for people who want to estimate fixed deposit returns in different currencies.
What Is a Fixed Deposit Calculator
A Fixed Deposit Calculator is a financial tool used to estimate the returns on money invested for a specific period at a given interest rate.
When you open a fixed deposit with a bank or financial institution, you deposit a certain amount for an agreed tenure. Depending on the deposit scheme, interest may be compounded or calculated using a simple interest method.
The calculator helps you understand how your deposit may grow over time. It can be useful when comparing investment periods, reviewing interest rates, and planning your savings.

Fixed Deposit Interest Calculation Formula
The calculator uses different formulas depending on the selected interest type.
Compound Interest Formula
The compound interest calculation used by this tool is:
A = P × (1 + R/100)ᵗ
Where:
A = Final maturity amount
P = Original deposit amount
R = Annual interest rate in percentage
t = Investment period in years
The estimated interest earned is calculated as:
Interest Earned = Maturity Amount − Principal
This calculator applies the annual compounding formula. Actual bank FD returns can differ when the bank compounds interest quarterly, monthly, or according to another schedule.
Simple Interest Formula
For simple interest, the calculator uses:
A = P × (1 + RT/100)
Where:
A = Final amount
P = Original deposit
R = Annual interest rate
T = Investment period in years
With simple interest, the interest is calculated on the original deposit rather than adding previously earned interest to the principal.
Fixed Deposit Calculator Example
Suppose you invest ₹1,00,000 at an annual interest rate of 7% for 5 years.
Using the compound interest formula in this calculator, the estimated results are:
| Deposit Details | Amount |
|---|---|
| Initial Deposit | ₹1,00,000 |
| Annual Interest Rate | 7% |
| Investment Period | 5 Years |
| Interest Type | Compound |
| Estimated Interest Earned | ₹40,255.17 |
| Estimated Maturity Amount | ₹1,40,255.17 |
These figures are mathematical estimates based on annual compounding. Your actual bank maturity amount may be different depending on the bank’s interest calculation method, compounding frequency, deposit terms, and applicable taxes.

Compound Interest vs Simple Interest
Compound interest and simple interest calculate returns differently.
With simple interest, earnings are calculated on the original deposit throughout the investment period. With compound interest, previously earned interest is included in the amount used to calculate subsequent interest, according to the compounding schedule.
For the same positive interest rate and investment period, compound interest will generally produce a higher result than simple interest when interest is compounded more than once over the period. However, the exact result depends on the applicable terms.
Banks may use different interest calculation and compounding methods for their FD products. Always check the bank’s official terms before investing.
Factors That Affect Fixed Deposit Returns
Deposit Amount
A higher deposit generally produces more interest when the interest rate and investment period remain the same.
Interest Rate
The annual interest rate has a direct effect on the estimated earnings. Compare the rates offered by different banks and financial institutions before making a decision.
Investment Period
The tenure determines how long your money remains invested. A longer period may increase total interest, although the available rates and withdrawal conditions can vary.
Interest Calculation Method
Simple interest, annual compounding, quarterly compounding, and other calculation methods can produce different maturity amounts.
Taxes and Bank Terms
The calculator does not include tax deductions, penalties for premature withdrawal, special senior-citizen rates, or other bank-specific conditions. These may affect your actual returns.
Important Things to Know Before Investing in an FD
Confirm the interest rate and tenure with the bank or financial institution.
Check whether interest is paid periodically or at maturity.
Verify the compounding frequency and maturity calculation method.
Review premature withdrawal rules and any applicable penalties.
Consider taxes and other conditions that may affect your final return.
Keep your financial goals and need for access to money in mind before locking funds into a deposit.
The country and currency selectors in this tool are for selecting the displayed country and currency. Changing them does not automatically convert the deposit amount using foreign exchange rates or retrieve current bank interest rates.
Conclusion
The Fixed Deposit Calculator is a useful tool for estimating the interest earned and maturity amount on a deposit. Enter your investment amount, annual interest rate, and tenure, then select the interest calculation method to view the estimated results.
Use the calculator to compare possible savings outcomes and plan your investments. Before opening an FD, verify the applicable rate, compounding method, taxes, and maturity amount with your bank or financial institution.
