HDFC FD Calculator
Estimate your maturity amount using indicative HDFC fixed deposit slab rates. You can also enter a custom rate manually.
What this HDFC fixed deposit interest rates calculator does
This tool helps you quickly estimate how much your HDFC Bank FD could grow over a selected period. You enter deposit amount, tenure in days, customer type, and FD mode, and the calculator shows estimated interest and maturity value.
Unlike generic FD tools, this page also supports indicative slab-based HDFC rates, which can auto-fill your rate field based on tenure and whether you are a general or senior citizen depositor.
How FD returns are calculated
1) Cumulative FD
In cumulative deposits, interest is reinvested and compounded. A standard formula is:
A = P × (1 + r/n)(n×t)
- P = principal amount
- r = annual rate in decimal form
- n = compounding frequency per year
- t = time in years
2) Non-cumulative FD
In non-cumulative options, interest is usually paid out periodically (monthly/quarterly/etc.), so compounding benefit is lower. The calculator uses a simple estimate:
Interest = P × r × t
Indicative HDFC FD slab rates used in this calculator
The calculator auto-fills rates using a tenure-band approach. These values are meant for planning and comparison:
| Tenure (Days) | General Citizen | Senior Citizen |
|---|---|---|
| 7 – 29 | 3.00% | 3.50% |
| 30 – 45 | 3.50% | 4.00% |
| 46 – 89 | 4.50% | 5.00% |
| 90 – 182 | 4.50% | 5.00% |
| 183 – 270 | 5.75% | 6.25% |
| 271 – 364 | 6.00% | 6.50% |
| 365 – 539 | 6.60% to 7.10% | 7.10% to 7.60% |
| 540 days and above | ~7.00% | ~7.50% |
How to use this calculator correctly
- Enter your FD amount in rupees.
- Enter exact tenure in days (for better slab matching).
- Select General or Senior Citizen.
- Select Cumulative or Non-Cumulative mode.
- Keep auto-rate ON for slab-based estimate, or switch it OFF and input your own rate.
- Click Calculate FD Return.
Example scenarios
Example A: ₹1,00,000 for 365 days (General, cumulative)
If the selected slab rate is 6.60% and compounding is quarterly, maturity will be higher than simple interest because each quarter’s interest also earns interest.
Example B: ₹5,00,000 for 730 days (Senior, cumulative)
With senior citizen benefit and a longer term, the total interest can rise significantly compared with short-tenure deposits.
Key factors that affect your FD maturity value
- Tenure: Longer tenure usually means higher total interest.
- Rate lock-in: FD rate is typically fixed at booking time.
- Customer category: Senior citizens often receive additional rate benefit.
- Payout mode: Cumulative generally yields better maturity due to compounding.
- Premature withdrawal: Can reduce effective yield due to penalties.
Tax note for Indian FD investors
Interest earned on bank FD is taxable as per your income tax slab. TDS rules may apply depending on total annual interest and applicable declarations. This calculator does not replace tax advice—use it for pre-tax estimates and planning.
