FD Calculator India – How to Use and What to Know
This FD calculator works with three inputs: the deposit amount, the annual interest rate, and the tenure in months. It then shows the maturity amount and total interest earned, giving you a quick way to compare offers from different banks before you commit funds.
Cumulative vs Non-cumulative FDs
The biggest choice before entering values here is whether your FD is cumulative or non-cumulative. In a cumulative FD, interest is not paid out periodically — it is reinvested and compounds until maturity. The amount shown by this calculator reflects a cumulative structure where interest rolls up to the final payout.
A non-cumulative FD pays interest monthly, quarterly, or half-yearly to your linked savings account, so the compounding effect is reduced. If you use this calculator for an income-payout FD, treat the maturity figure as an approximation of the underlying compounding and not as your actual cash-flow schedule.
Compounding Frequency and Effective Yield
Most Indian bank FDs compound interest quarterly. When your bank quotes 7% per annum with quarterly compounding, the effective annual yield is slightly above 7% because every quarter's interest starts earning interest immediately in the next period. The standard formula is:
A = P × (1 + r / n)n × t
where P is the principal, r is the annual rate as a decimal, n is compounding periods per year (4 for quarterly), and t is tenure in years. This calculator uses quarterly compounding as the baseline. If your bank compounds monthly or annually, the maturity value will differ slightly.
Senior-citizen Rate and Rate Matching
Many banks offer an additional 0.25–0.50% on FD rates for depositors aged 60 and above. This calculator does not automatically detect your age — simply enter the rate your bank quotes for your category (regular or senior citizen) and the result will reflect that rate correctly. When comparing two banks, run separate calculations for each quoted rate.
Tax on FD Interest and TDS
FD interest is taxed as "Income from Other Sources" at your applicable income-tax slab rate. Banks deduct TDS when your aggregate interest income with that bank crosses ₹40,000 in a financial year (₹50,000 for senior citizens under current rules). TDS is an advance against your final tax liability — not the complete tax. This calculator shows gross (pre-tax) maturity; apply your own slab rate to the interest figure to estimate your post-tax outcome.
Tax-saving 5-year FDs under Section 80C lock principal for five years. The deposit may be eligible for a deduction up to the Section 80C limit, but the interest earned remains fully taxable each year.
FD Calculator India – FAQs
Does this calculator work for both cumulative and non-cumulative FDs?
It models a cumulative FD where interest rolls up until maturity. For non-cumulative (income payout) FDs, the maturity figure is an approximation — your actual periodic interest payments arrive before the end date.
What compounding frequency does this tool assume?
Quarterly compounding, which is the standard most Indian banks use for FDs. If your bank uses monthly or annual compounding, actual maturity will be slightly different from this estimate.
How do I use this for a senior-citizen FD rate?
Enter the senior-citizen rate quoted by your bank in the interest rate field. The calculator does not detect age automatically — enter whichever rate applies to you and the result will reflect it correctly.
Is the maturity amount shown pre-tax or post-tax?
Pre-tax (gross). Apply your income-tax slab rate to the interest amount shown to estimate post-tax return. TDS deducted by the bank counts as advance tax, not final tax.
What is the TDS threshold on FD interest?
Under current rules, TDS is deducted when your total FD interest income with one bank crosses ₹40,000 in a financial year (₹50,000 for senior citizens). Form 15G/15H can exempt eligible taxpayers from TDS deduction but does not eliminate the underlying tax liability.
Can I compare two bank FD offers using this tool?
Yes. Run separate calculations with each bank's rate and tenure, note both maturity amounts, then factor in post-tax return and any premature withdrawal penalties before making a choice.
