Last year, my uncle had a simple goal: park his savings safely, earn predictable returns, and know the exact amount he would receive on maturity.
He did not want guesswork. That is where a fixed deposit calculator becomes useful, because it shows how the interest rate and tenure affect your final corpus before you lock your money in a fixed deposit.
In this guide, we will look at how interest rates and tenure shape your FD maturity value, why compounding and payout choices matter, and how real FD rates-such as Bajaj Finance FD-can help you plan better.
Understanding FD maturity value
Your FD maturity value is the total amount you receive when the deposit tenure ends. It includes your principal plus the interest earned during the tenure.
If you choose a cumulative FD, interest is added back to the principal at periodic intervals and compounds over time. This "interest on interest" increases the final maturity value.
If you choose a non-cumulative FD, interest is paid out periodically. Bajaj Finance offers the following non-cumulative payout options:
●Monthly
●Quarterly
●Half-yearly
●Yearly
In such cases, the maturity value usually equals the principal amount, since interest is paid during the tenure.
The two factors that decide maturity value
Interest rate determines growth
A higher interest rate increases the total interest earned during the tenure. Even a small difference-such as 0.20% to 0.40%-can significantly change the final value when compounding is involved.
Comparing rates across issuers and tenure slabs is therefore important when selecting an FD.
Tenure determines compounding time
Tenure decides how long your deposit remains invested. A longer tenure allows interest to accumulate and compound more times.
Shorter FDs offer flexibility, while longer tenures may increase the maturity value when the rate remains competitive.
How interest rate affects maturity value
The interest rate acts like the growth engine of your FD. For the same principal and tenure, a higher rate produces a higher maturity value.
For example, investing Rs. 1,00,000 for 24 months at 6.75% p.a. generates less interest than investing at 6.95% p.a. or 7.30% p.a.. The difference grows further when interest compounds in a cumulative FD.
Interest rates may also differ depending on payout options. Periodic payout options may offer slightly lower rates compared with cumulative deposits.
How tenure affects maturity value
Tenure directly affects the total interest earned. The longer the tenure, the more time interest has to accumulate.
For example, if you are saving for a near-term expense, a shorter FD may be suitable. However, if the goal is several years away, choosing a longer tenure can increase the maturity value due to compounding.
Using a fixed deposit calculator to compare multiple tenure options helps illustrate how maturity values change with time.
Compounding and payout frequency
Cumulative option
In the at-maturity option, interest compounds within the deposit. This option is typically chosen for long-term savings goals where a lump sum amount is required later.
Non-cumulative options
If you choose monthly, quarterly, half-yearly, or yearly payouts, interest is credited periodically to your bank account. These options are commonly used for income needs.
Since interest is paid out, it does not fully compound within the deposit, which can affect the total interest earned.

Using a fixed deposit calculator effectively
To estimate returns accurately:
●Enter the deposit amount you plan to invest.
●Select the tenure based on your goal timeline.
●Choose the interest rate (p.a.) for your age category.
●Select the payout frequency (cumulative or non-cumulative).
●Compare maturity values across two or three tenure options.
Tax and TDS considerations
Interest earned from fixed deposits is taxable under "Income from Other Sources."
For NBFC fixed deposits such as Bajaj Finance FD:
●TDS at 10% is deducted if interest exceeds Rs. 10,000 in a financial year
●If PAN is not submitted, TDS may be deducted at 20%
If your total income is below the basic exemption limit, you may submit Form 15G or Form 15H to avoid TDS deduction.
Conclusion
Your FD maturity value mainly depends on the interest rate and tenure, while payout frequency fine-tunes the outcome. By using a fixed deposit calculator and comparing tenure slabs and payout options, you can estimate returns with greater clarity. Evaluating products such as Bajaj Finance Fixed Deposits, along with their rates and payout choices, can help you select the structure that best fits your financial goals.
