How the FD estimate is calculated

The calculator uses Maturity = Deposit × (1 + Annual rate ÷ 4)4 × Time. This assumes interest is compounded quarterly and retained in the deposit until maturity.

Deposit

A single investment made at the beginning of the selected tenure.

Compounding

The entered annual rate is divided across four compounding periods each year.

Assumptions

The rate stays constant; premature withdrawal, tax, TDS, and bank-specific rules are excluded.

Worked fixed-deposit example

For a one-time deposit of ₹1,00,000 at 7.1% per year for 5 years with quarterly compounding, the calculator estimates:

Deposited
₹1,00,000
Estimated interest
₹42,175
Estimated maturity
₹1,42,175

Frequently asked questions

Does every bank compound FD interest quarterly?

Not necessarily. Products can use different compounding or payout schedules. This calculator consistently uses quarterly compounding for comparison.

Does the result include TDS or income tax?

No. The result is a gross estimate before tax, TDS, penalties, and other deductions.

What happens if I close the FD early?

Premature closure can change the applicable rate and may attract a penalty. Those product-specific rules are not modelled.
