How cumulative deposit interest grows

The principal and accumulated interest earn another quarter of interest at annual rate ÷ 4. Quarter boundaries are anchored to the deposit date, with month-end clamping. After the last complete quarter, the remaining days earn simple interest on that balance at annual rate × days ÷ 365.

Use the rate on your deposit advice

Choose the opening date and maturity date instead of guessing the length in years. The bank’s contracted rate may depend on age, booking date and product. The sample 7% is an illustration, not a current offer. This tool models accumulation, not monthly interest payouts.

A one-year example

A ₹1,00,000 deposit from 1 April 2026 to 1 April 2027 at 7% compounds four times: 100000 × (1 + 0.07/4)^4 = ₹1,07,185.90. Gross interest is ₹7,185.90 before tax. The table shows how the balance reaches that amount.

Why your bank’s amount may differ

The result excludes TDS, tax liability, penalties and premature closure. Actual banks may use different day-count conventions or interim rounding. SBI documents completed-quarter compounding and a 365-day basis for broken periods; confirm the convention on your own fixed-deposit receipt.

FD Maturity Calculator FAQs

Is this FD result after TDS?

No. FD Maturity Calculator shows gross contractual growth. Tax withholding can affect the amount credited and depends on your circumstances; no withholding rate or threshold is assumed.

Does February or a leap year change the calculation?

Dates are processed as calendar dates in UTC. Complete quarters are counted from the start date; leftover days use actual elapsed days with a 365-day denominator, including when those days fall in a leap year.
