A principal, a rate and a tenure in years, months and days give the interest and the maturity. Quarterly compounding is the default. You can switch to a payout, and see the amount after a tax slab you choose.

How interest is paid
Cumulative adds interest back. Payout is simple interest, and the principal comes back at the end.
Compounding
Quarterly is the usual bank default. A leftover shorter than one period earns simple interest.

No year of this deposit crosses it
The slab is 0%, so no income tax is shown. Pick your slab to see tax and cess. Section 153 is not applied.
No year of this deposit crosses ₹50,000 of interest, so this deposit alone would not cross the Section 393 TDS line. Other deposits at the same bank still count.
A cumulative deposit adds the interest back, so later periods earn interest on interest. A payout pays simple interest and does not add it back. The principal comes back at the end.
For a cumulative deposit, whole quarters, months, half-years or years compound. A shorter leftover earns simple interest. A year in the year box is 12 months. Extra days use a 365-day year. 365 days matches 1 year. One month is one-twelfth of a year, not 30 days.
The formula in plain words
Cumulative maturity is the principal, times (1 + yearly rate divided by the number of periods) to the power of the whole periods, times (1 + yearly rate times any leftover fraction of a year). Payout interest is the principal times the yearly rate times the length in years. It is rounded to the nearest rupee once.
Tax is that interest times the slab you pick. Cess is 4% of the tax. Each is rounded, then added. TDS is not taken off again.
A worked example
₹1,00,000 for 1 year at 6.25%, compounded quarterly. Maturity is ₹1,06,398. Interest is ₹6,398. The same deposit as a payout pays ₹6,250 and returns the principal of ₹1,00,000.
At a 30% slab, tax on the cumulative interest is ₹1,919. Cess is ₹77. Together that is ₹1,996. After tax you receive ₹1,04,402. The interest is under ₹50,000, so this one deposit would not cross the TDS line.
6.25% is SBI retail card, 1 year to less than 2 years, below ₹3 crore, general public. It has been in force from 15 December 2025. SBI's card was last updated 19 October 2026. It is one bank's card, not a market rate. Type the rate you were offered.
Tax, TDS and the senior-citizen rate
Section 393 of the Income-tax Act, 2025 (this was section 194A) lets a bank deduct 10% if you have given your PAN and the interest it credits in a tax year crosses ₹50,000. For a person who is 60 or older, that line is ₹1,00,000. The comparison is each year, not the interest over the whole tenure. TDS is a collection. Your return settles the real tax.
Section 153 (this was Section 80TTA and Section 80TTB) is separate. Under 60, the deduction of up to ₹10,000 is for savings accounts, not fixed deposits. A senior citizen who is not under Section 202 can deduct up to ₹50,000, and that can include a fixed deposit. Section 202 does not allow Section 153. This calculator does not apply it.
The starting rate is not a senior-citizen rate. SBI pays 0.50 percentage points more than 6.25% on the 1-year public bucket. Longer buckets can differ, because some banks add a further senior extra. Type the number on your card. The Income-tax Act, 2025 has been in force from 1 April 2026. FY 2025-26 still uses the 1961 section numbers.
Assumptions and limits
The rate stays the same for the whole tenure. A bank can revise the card for a new deposit.
There is no penalty for breaking the deposit early. That penalty is not modelled.
Surcharge is not included. The basic exemption is not included, because your other income is unknown.
Year rows are rounded on their own. They can differ from the headline by a rupee.
The senior-citizen box changes only the TDS note.

Questions
Why is quarterly compounding the default?
Most bank fixed deposits compound every quarter. You can switch to monthly, half-yearly or yearly. Interest payout is simple interest: the interest is not added back, and the principal comes back at the end.
Does this include TDS?
The maturity and the tax line do not subtract TDS. Section 393 lets a bank deduct 10% when the interest it credits in a tax year is more than ₹50,000, or more than ₹1,00,000 if you are 60 or older, and you have given your PAN. The note on the result counts years for this deposit alone. Other deposits at the same bank count too. TDS is adjusted in your return. It is not a second tax.
Where is the extra rate for senior citizens?
It is not added for you. Banks print a higher card rate. On the SBI card used here, the 1-year public rate is 6.25%, and senior citizens are paid 0.50 percentage points more on that bucket. Type the rate from your own card. The box for age 60 or older only changes the TDS line.
Is the maturity after tax?
No. The maturity is before tax. Pick your slab to see tax and the 4% cess on that tax. The default slab is 0%, so the tool does not assume a bracket. Section 153 (this was Section 80TTA for savings accounts, and Section 80TTB for senior citizens) is not applied. FD interest is not covered by the ₹10,000 savings-account deduction. A senior citizen who is not under Section 202 can deduct up to ₹50,000 of interest, including FD interest. This page does not take that deduction, because your other interest and your tax regime are not entered.
PPF interest is tax-free and follows a government rate. The PPF calculator uses that rate and the 15-year term.
