Cumulative compounding payout FDs are not this curve
A = P(1 + r/n)nt with n defaulting to 4 (quarterly). ₹1 lakh at 7.5% for 5 years is about ₹1.450 lakh quarterly, ₹1.453 lakh monthly, ₹1.436 lakh annually. Frequency is a small gap.
Payout FDs send interest out; maturity stays near principal. ₹5 lakh at 7% for 5 years quarterly cumulative is about ₹7.07 lakh. TDS, premature-break, and senior-citizen extra are not in the loop. FD compounding note. SIP vs FD.
Frequency is a small gap
Motion is the same maths as the worksheet. Reduced-motion browsers skip the grow.

When to use this calculator
Use this page to see cumulative FD maturity at a rate and compounding frequency you type, and to compare how often interest is added.
How to read your result
Invested amount is principal. Estimated returns are interest. Total value is A = P(1 + r/n)^(n t) for a cumulative FD. Payout FDs send interest out; they are not this curve.
The rate is from your bank’s letter (or a planning guess). TDS and premature-break penalties are not subtracted in the loop.
Key assumptions and limitations
- Cumulative compounding at n = 12, 4, or 1 as you select; default on this site is quarterly unless you change it.
- Interest rate is whatever you enter — not a live rate card.
- Company FDs and bank FDs are not distinguished in the formula; DICGC and credit risk are copy, not maths.
Common mistakes
- Using a cumulative curve to plan a monthly-interest payout FD.
- Picking a bank on monthly versus quarterly when the gap is small.
- Treating an NBFC “company FD” as if it had the same deposit insurance as a bank FD.

What I check on an FD
- Bank versus company FD. DICGC is ₹5 lakh per bank, typically none on NBFC deposits.
- Payout versus cumulative. This curve is cumulative. A monthly-interest FD stays near principal.
- Frequency is a small gap. I do not pick a bank on monthly versus quarterly.
Bank FD vs company FD insurance is the difference, not the compounding tab
Monthly vs quarterly vs annual on the same bank FD is a small gap. An NBFC 'company FD' at a fatter rate is a different credit.
| Issuer | Deposit insurance | Rate extra |
|---|---|---|
| Scheduled commercial bank | DICGC: ₹5 lakh per bank per depositor (principal + interest) | Senior-citizen extra is a bank product, not in the default slider |
| Small finance / co-op bank | Usually the same DICGC cap if they are insured members confirm | Higher advertised rate is still capped at ₹5 lakh of cover |
| NBFC / housing-finance 'company FD' | Typically none | The extra percent is credit risk, not a compounding trick |
Split large deposits across banks if you care about the ₹5 lakh cap. Payout FDs are not this cumulative curve.
A = P(1 + r/n)^(n t). Gap is small. Payout vs cumulative is not.
