About the IOB FD Calculator

Indian Overseas Bank (IOB), headquartered in Chennai, offers fixed deposits across short and long tenures with interest compounded quarterly. IOB FD rates differ by tenure and depositor category, and senior citizens usually earn a premium over the standard rate. Use this IOB FD calculator to see an estimated maturity value for your chosen amount and period.

What is an FD Calculator?

An FD calculator estimates the maturity amount of a fixed deposit from three inputs: the deposit amount, the annual interest rate, and the tenure. Banks in India compound fixed deposit interest quarterly on most schemes, which means interest earns interest every quarter and the effective yield is slightly higher than the quoted rate.

How Does the IOB FD Calculator Work?

The calculator uses the compound interest formula with quarterly compounding:

A = P x (1 + r/4/100)^(4 x t)

A is the maturity amount.
P is the deposit amount.
r is the annual interest rate.
t is the tenure in years.

Example

For a deposit of Rs. 2,50,000 for 5 years at an assumed 6.8% per year compounded quarterly, the maturity value works out to about Rs. 3,50,235, which includes roughly Rs. 1,00,235 in interest. Your actual rate depends on the current rate card for your tenure, so treat this as an illustration.

Frequently Asked Questions

Does IOB offer a monthly interest payout option on FDs?

Yes. Indian Overseas Bank lets you choose quarterly or monthly interest payouts on eligible tenures, which is useful if you want regular income instead of reinvestment.

How is FD interest calculated?

Most banks compound FD interest quarterly, so the formula is A = P x (1 + r/4/100)^(4t). Quarterly compounding adds a small yield advantage over simple interest at the same nominal rate, which the calculator reflects in the maturity value of Rs. 3,50,235.

Is FD interest taxable?

Yes. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS when annual interest crosses the current threshold, which is higher for senior citizens under the latest budget rules. Submit Form 15G or 15H if your total income is below the taxable limit.

Can I withdraw my FD before maturity?

Yes, banks allow premature closure, but they pay interest at the rate applicable to the period the deposit actually stayed, often with a small penalty. Deposit insurance covers up to Rs. 5 lakh per depositor per bank through DICGC.
