Module C: Formula & Methodology Behind the Calculator
The calculator uses the compound interest formula to determine FD maturity amounts:
A = P × (1 + r/n)nt
Where:
A = Maturity amount
P = Principal amount
r = Annual interest rate (decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for (in years)
For simple interest calculations (used for some short-term FDs):
A = P × (1 + r × t)
The calculator automatically adjusts for:
- Different compounding frequencies (daily to annually)
- Senior citizen rate adjustments (+0.5%)
- Partial year calculations (for months/days)
- Day count conventions (365/366 days)

Module G: Interactive FAQ About IDBI Bank FD Calculations
How does IDBI Bank calculate interest on fixed deposits?
IDBI Bank uses compound interest calculation for most FDs, where interest is calculated on the principal plus previously accumulated interest. The formula is A = P(1 + r/n)^(nt), where n is the compounding frequency (typically 4 for quarterly). For monthly payout FDs, simple interest is used: Interest = P×r×t.
What’s the minimum and maximum amount for IDBI FD?
The minimum deposit amount for IDBI regular FDs is ₹10,000, while for tax-saving FDs it’s ₹100. There’s no maximum limit, but deposits above ₹5 lakh may have different terms. For senior citizens, the minimum remains the same but they get preferential rates.
Can I break my IDBI FD prematurely? What are the penalties?
Yes, you can break IDBI FDs prematurely, but penalties apply:
- For FDs < ₹5 lakh: 1% penalty on the contracted rate
- For FDs ≥ ₹5 lakh: 0.5% penalty
- No interest for FDs broken before 7 days
- Tax-saving FDs (5 years) cannot be broken prematurely
How is TDS calculated on IDBI FD interest?
IDBI Bank deducts TDS at 10% if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). For example:
- ₹5 lakh FD at 7.5% for 1 year earns ₹37,500 – no TDS
- ₹6 lakh FD at 7.5% earns ₹45,000 – ₹4,500 TDS deducted
What’s the difference between cumulative and non-cumulative FDs in IDBI?
Cumulative FDs (our calculator’s default) compound interest until maturity, giving higher returns. Non-cumulative FDs pay interest periodically (monthly/quarterly), which is better for regular income needs. Example for ₹10 lakh at 7.5% for 3 years:
- Cumulative: Maturity amount ₹12,423,000 (interest ₹2,423,000)
- Non-cumulative (quarterly): Quarterly payout ₹18,750; maturity amount ₹10,00,000
Does IDBI offer special FD rates for NRIs?
Yes, IDBI offers special NRE and NRO FD rates for NRIs:
| Tenure | NRE FD (%) | NRO FD (%) |
|---|---|---|
| 1 year | 7.25 | 7.00 |
| 2 years | 7.50 | 7.25 |
| 3-5 years | 7.75 | 7.50 |
How often does IDBI Bank change FD interest rates?
IDBI Bank typically reviews FD rates quarterly, but may change them more frequently based on:
- RBI repo rate changes (usually within 1-2 months of RBI announcements)
- Liquidity conditions in the banking system
- Competition from other banks
- Government securities yields
