Fixed Deposits remain one of India's most trusted investments — guaranteed returns, zero market risk, available at every bank. But before locking in your money, you need to know exactly what you will earn. A free FD calculator gives you that answer instantly.

What is a Fixed Deposit?

A Fixed Deposit is a savings instrument where you deposit a lump sum with a bank for a fixed tenure — from 7 days to 10 years — at a predetermined interest rate. Unlike savings accounts, the FD rate is locked at the time of deposit, protecting you from rate cuts during your tenure.

FDs are insured by DICGC (Deposit Insurance and Credit Guarantee Corporation) up to Rs 5 lakh per depositor per bank, making them one of the safest investments in India.

How FD Interest is Calculated

FD interest is calculated using two methods. Simple Interest: Interest = Principal x Rate x Time divided by 100. Compound Interest for cumulative FDs: A = P x (1 + r/n)^(n x t), where A is maturity amount, P is principal, r is annual rate, n is compounding frequency (quarterly = 4), and t is years.

Most bank FDs compound quarterly. Use our calculator to get instant results for any combination of amount, rate, and tenure.

Cumulative vs Non-Cumulative FD — Which to Choose?

Cumulative FD: Interest compounds and is paid at maturity with principal. Best for wealth creation — you get the full power of compounding. Ideal if you do not need regular income.

Non-Cumulative FD: Interest paid at regular intervals — monthly, quarterly, or annually. Best for retirees who need regular income. Interest rate is slightly lower because it is not reinvested.

Tax-Saving FD: 5-year lock-in, qualifies for deduction under Section 80C up to Rs 1.5 lakh. Available at all major banks.

Best FD Rates in India 2025

Bank TypeGeneral RateSenior Citizen Rate
SBI and large PSU banks6.5 to 7.0%7.0 to 7.5%
HDFC, ICICI, Axis Bank6.6 to 7.2%7.1 to 7.7%
Small Finance Banks7.5 to 9.0%8.0 to 9.5%

Always verify current rates on the bank website before investing. Small Finance Banks offer higher rates but are riskier — stick to DICGC insured amounts (Rs 5 lakh limit per bank).

FD vs SIP — Which Gives Better Returns?

FD gives guaranteed returns with zero risk, but at 6 to 7% annual return, it barely beats inflation (5 to 6%), giving very low real returns. SIP in equity mutual funds has historically given 10 to 14% annual returns with no guarantee but strong inflation-beating growth over 5 or more years.

The right choice depends on your goal: FD for short-term safety (1 to 3 years), SIP for long-term wealth creation (5 or more years). Use our free SIP calculator to compare returns side by side.

Tax on FD Interest — What You Need to Know

FD interest is fully taxable as income from other sources at your applicable income tax slab rate. Banks deduct TDS at 10% if annual interest exceeds Rs 40,000 (Rs 50,000 for senior citizens). If your total income is below the taxable limit, submit Form 15G or 15H to avoid TDS deduction.

Frequently Asked Questions

What happens to FD if the bank fails?

FD deposits are insured by DICGC up to Rs 5 lakh per depositor per bank. If the bank fails, DICGC compensates up to this limit. Spread FDs across different banks if your investment exceeds Rs 5 lakh.

Can I break FD before maturity?

Yes, most FDs allow premature withdrawal with a penalty of 0.5 to 1% on the applicable interest rate. Some banks offer zero-penalty withdrawal after 3 months. Check terms before investing.

What is the minimum FD amount?

Most banks allow FDs from Rs 1,000. SBI minimum is Rs 1,000, HDFC is Rs 5,000. Small finance banks vary. Post Office FDs start at Rs 1,000.

Is FD better than RD?

FD is better if you have a lump sum to invest. RD (Recurring Deposit) is better for monthly savings. Both are equally safe. FD interest is slightly higher than RD for the same tenure.
