Fixed deposits use the compound interest formula to calculate the maturity amount. Unlike simple interest, compound interest earns interest on previously accumulated interest, which leads to faster growth of your deposit over time.
The standard formula used by banks to calculate FD maturity is:
Where:
| Variable | Meaning |
|---|---|
| A | Maturity amount (principal + interest) |
| P | Principal deposit amount (e.g., &rupee;1,00,000) |
| r | Annual interest rate (in decimal, e.g., 7.1% = 0.071) |
| n | Compounding frequency per year (4 for quarterly, 12 for monthly) |
| t | Tenure in years |
Suppose you invest &rupee;1,00,000 in an FD at 7.1% p.a. for 5 years with quarterly compounding:
So your total interest earned would be approximately &rupee;41,902 over 5 years. Notice how quarterly compounding earns you slightly more than simple interest would (&rupee;35,500), because each quarter’s interest begins earning its own interest in subsequent quarters.
Here is a comparison of fixed deposit interest rates offered by major Indian banks for general customers on a 5-year FD. Senior citizens typically receive an additional 0.25% to 0.75% above these rates.
| Bank / Institution | FD Rate (General) | FD Rate (Senior Citizen) |
|---|---|---|
| Post Office (POTD) | 7.50% | 7.50%* |
| SBI | 7.10% | 7.60% |
| PNB | 7.05% | 7.55% |
| HDFC Bank | 7.00% | 7.50% |
| ICICI Bank | 7.00% | 7.50% |
* Post Office does not offer a separate senior citizen rate for POTD. Rates are approximate and subject to change. Always verify with the bank before investing.
A Fixed Deposit (FD) requires a one-time lump sum investment for a fixed tenure, while a Recurring Deposit (RD) involves depositing a fixed amount every month for a set period. FDs generally offer slightly higher interest rates than RDs at the same bank. FD is best when you have a lump sum available to invest, whereas RD is suited for those who want to save a fixed amount from their monthly income. Both are considered safe investments backed by the bank and are covered under the DICGC insurance scheme up to &rupee;5 lakh per depositor per bank.
Yes, banks deduct TDS (Tax Deducted at Source) on FD interest if the total interest earned across all your FDs in that bank exceeds &rupee;40,000 in a financial year (&rupee;50,000 for senior citizens). TDS is deducted at 10% if you have provided your PAN to the bank, and at 20% if PAN is not on file. To avoid TDS when your total income is below the taxable limit, submit Form 15G (or Form 15H if you are a senior citizen) at the beginning of each financial year.
FD rates change frequently and vary across institutions. As of early 2026, India Post offers around 7.50% for 5-year deposits, SBI offers approximately 7.10%, PNB around 7.05%, and HDFC Bank and ICICI Bank offer about 7.00% for general customers. Small finance banks like AU Small Finance Bank and Ujjivan Small Finance Bank may offer higher rates (up to 8–9%). Always compare the latest rates on the bank’s official website or RBI’s portal before making a decision.
A tax-saver FD is a special 5-year fixed deposit that qualifies for a tax deduction under Section 80C of the Income Tax Act, up to a maximum of &rupee;1.5 lakh per financial year. The key difference from a regular FD is the mandatory 5-year lock-in period — premature withdrawal or loan against the deposit is not allowed. The interest earned on a tax-saver FD is fully taxable as per your income tax slab and is subject to TDS if it exceeds the threshold.
Most banks allow premature withdrawal of regular FDs but impose a penalty, typically a 0.5% to 1% reduction from the applicable interest rate for the period the deposit was held. For example, if you break a 5-year FD after 2 years, the bank will pay the 2-year FD rate minus the penalty. Some banks also offer partial withdrawal or sweep-in facilities. Note that tax-saver FDs with a 5-year lock-in cannot be withdrawn before maturity under any circumstances.
Yes, nearly all banks in India offer an additional 0.25% to 0.75% interest on FDs for senior citizens (aged 60 years and above). Some banks offer a further premium for super senior citizens (aged 80+). For instance, if a bank’s general FD rate for 5 years is 7.10%, senior citizens might receive 7.60% or higher. Additionally, the TDS threshold for senior citizens is &rupee;50,000 (versus &rupee;40,000 for others), and they can submit Form 15H to avoid TDS altogether if their income is below the taxable limit. This makes FDs especially popular among retirees for regular income.
