Estimate the maturity value of a cumulative fixed deposit using the quoted annual rate, tenure, and compounding frequency. Change the frequency only when the bank’s product terms use that convention.

Assumes a cumulative FD at a constant rate. Bank day-count, compounding dates, premature closure, TDS, and tax are not included.

What this FD calculator shows

  • Principal deposited.
  • Estimated interest over the selected period.
  • Estimated maturity value.

Fixed deposit formula

The calculator uses the compound-interest formula:

Fixed deposit formula

Maturity value = P x (1 + r / n)^(n x t)

Here, P is the deposit, r is the annual rate as a decimal, n is the number of compounding periods per year, and t is the tenure in years. Quarterly compounding uses four periods per year.

For example, Rs. 1,00,000 at 7% for five years with quarterly compounding grows to about Rs. 1,41,478 before tax and product-specific adjustments.

What can make the bank value different

Banks can use exact deposit dates, day-count conventions, completed-quarter rules, special short-tenure methods, senior-citizen rates, and different premature-closure treatment. Non-cumulative deposits pay interest out instead of reinvesting it, so this maturity formula is not suitable for a payout FD.

The estimate excludes TDS and income tax. FD interest is generally taxable according to the applicable rules even when TDS is not deducted.

Common questions

Is quarterly compounding standard for every FD?

No. It is common for cumulative bank FDs, but product terms can use another frequency or a special convention for incomplete periods.

Does a higher compounding frequency always increase maturity?

At the same nominal annual rate and tenure, more frequent compounding normally produces a slightly higher value. Banks may quote effective yields differently, so compare the written maturity amount too.

Does the calculator include premature closure penalty?

No. Use the contracted premature-closure rate and penalty from the bank before breaking an FD.
