A Fixed Deposit remains a preferred choice for investors seeking stable and predictable returns. However, before investing, understanding applicable Fixed Deposit interest rates across tenures is essential. Using a fixed deposit calculator allows you to estimate maturity values in advance and align your investment with your financial goals.
Understanding Fixed Deposit Interest Rates
Fixed Deposit interest rates vary depending on the tenure and deposit amount. For deposits less than ₹3 crore (applicable from 17th December 2025), rates range from 2.75% for short tenures of 7–14 days to 6.45% for select tenures such as 18 months to 21 months and 21 months to 2 years. For longer tenures of 5 years 1 day to 10 years, the rate stands at 6.15% per annum. Senior Citizens are eligible for an additional premium over the regular rate for resident deposits.
How A Fixed Deposit Calculator Helps
A Fixed Deposit calculator simplifies return estimation by automatically applying the relevant interest rate based on the selected tenure and customer type. By entering the deposit amount, tenure in months or days, and choosing between Regular or Senior Citizen, the calculator displays:
- Estimated interest earned
- Total maturity amount
- Maturity date
Interest Calculation Methods
Interest on a Fixed Deposit is calculated differently depending on tenure and payout option. For deposits up to 6 months, Simple Interest is paid. For tenures above 6 months, interest may be paid quarterly, monthly or reinvested cumulatively. When the Reinvestment option is selected, quarterly interest is added to the principal, and future interest is calculated on the enhanced amount.
Senior Citizen Benefits
Resident individuals aged 60 years and above can benefit from higher Fixed Deposit interest rates. For example, in the 18 months to 21 months bucket (less than ₹3 crore), the regular rate is 6.45% while the Senior Citizen rate is 6.95% per annum. Senior Citizen rates do not apply to NRI deposits. The minimum tenure for NRE deposits is 1 year.
Example Of Estimated Returns
If you invest ₹1,00,000 for 12 months at an interest rate of 6.25% under the Reinvestment option, the estimated maturity amount shown by the fixed deposit calculator is ₹1,06,398. The total interest earned in this example would be ₹6,398. This value is approximate and does not include TDS deductions.
Booking a Fixed Deposit
Resident customers can book a Fixed Deposit through NetBanking by navigating to Accounts then Transact and then Open Fixed Deposit. Customers should verify the interest rate displayed on the confirmation screen before completing the booking.
Conclusion
Monitoring Fixed Deposit interest rates and using a fixed deposit calculator together ensures better financial planning. By understanding tenure-based rates, payout options, and applicable conditions, you can make informed decisions and optimise returns while maintaining capital safety.
