Cumulative FD compounds interest and pays everything at maturity. Interest is taxed per your income slab. Rates vary by bank — verify before investing.
How it works
Cumulative: A = P × (1 + r/n)^(n×t). Simple: interest = P × r × t.
Example: ₹1,00,000 at 7% quarterly for 5 years → ₹1,41,473 maturity.
Frequently Asked Questions
How is FD maturity value calculated?
For a cumulative FD, the maturity value is A = P × (1 + r/n)^(n×t), where r is the annual rate, n is the compounding frequency and t is the term in years. Simple FD pays P × r × t as interest without compounding.
What is the difference between cumulative and non-cumulative FD?
A cumulative FD reinvests the interest and pays everything at maturity, giving a higher effective return. A non-cumulative (simple/payout) FD pays interest periodically — monthly, quarterly or yearly — useful for a regular income stream.
Which banks offer the best FD rates?
As of August 2026, most public-sector banks offer around 6.5–7.0% for 5-year deposits (SBI 6.50%, PNB 7.25% senior citizen), while many small finance banks go up to 8.5%. Rates change frequently — check the bank's current rate before investing.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS at 10% if interest exceeds ₹40,000 in a year (₹50,000 for senior citizens) unless you submit Form 15G/15H.
What is the minimum tenure for an FD?
Most banks offer FDs from 7 days to 10 years. Simple interest applies to short tenures under about 90 days, and compounding starts for longer tenures — which is why this calculator switches behaviour by FD type.
