Formula and calculation method

A = P × (1 + r/n)^(n×t), where P is principal, r annual rate as decimal, n compounding periods yearly and t years. Interest = A − P.

Worked example

A ₹1,00,000 deposit at 7% compounded quarterly for one year is estimated using n = 4 and t = 1. Bank terms can change the actual amount.

Important information

This is not a bank quote or guaranteed return. Verify the bank's official deposit terms and applicable tax rules.

Frequently asked questions

How accurate is this calculator?

It provides an estimate based on the values and assumptions entered. Verify important decisions with the relevant provider or a qualified professional.

Does this replace professional advice?

No. It is an informational tool and does not replace tax, legal, accounting, lending, investment or medical advice.

Understanding an FD maturity estimate

For a ₹1,00,000 deposit, an annual rate assumption of 7% and quarterly compounding over one year, the compound-interest illustration uses four compounding periods. The result is an estimate; actual maturity proceeds depend on the bank's product terms, deposit dates, payout option and applicable rounding.

What to verify with the bank

Check whether the rate is cumulative or a periodic interest payout, the compounding frequency, premature-withdrawal penalty, minimum tenure, senior-citizen eligibility and tax deducted at source. Rates can change and are not guaranteed for future deposits. Confirm the final amount in the bank's official FD advice rather than relying only on this calculator.
