What a Fixed Deposit Is and How Banks Use Your Money
A fixed deposit (also called an FD) is an account where you give a bank or post office a sum of money for a set period — usually three months to ten years — and they pay you a fixed interest rate on top of what you deposited. You cannot withdraw the money before that period ends without paying a penalty. The bank uses your money to lend to other customers or invest it, and they return your original amount plus the interest when the term is over.
Fixed deposits are offered by commercial banks, cooperative banks, post offices, and some non-banking financial companies (NBFCs). The interest rate you receive depends on the bank, the amount you deposit, how long you lock the money away, and the current economic conditions. Rates change frequently — sometimes weekly — so two people opening an FD on different days may receive different returns even at the same bank.
The main appeal is certainty: you know exactly how much money you will have at the end, with no market risk. The main cost is that your money is locked away and you cannot access it without losing some of the interest you earned.
Key Takeaways
- You deposit a lump sum for a fixed period (three months to ten years), and the bank pays you a may provide interest rate on that amount.
- Interest rates vary by bank, deposit size, and term length, and change regularly — you must check the current rate at the time you open the account.
- Withdrawing money before the term ends usually costs you a penalty that reduces or eliminates the interest you earned.
- Fixed deposits are backed by deposit insurance up to ₹500,000 per depositor per bank through the Deposit Insurance and Credit may provide Corporation (DICGC).
- Interest earned on fixed deposits is taxable income and must be reported on your tax return in the year it is credited to your account.
Interest Rates and How Much You Actually Earn
The interest rate on a fixed deposit is set when you open the account and does not change for the entire term. A bank might offer 6.5% per year on a two-year deposit but 7.2% on a five-year deposit. Larger deposits often earn higher rates — depositing ₹1,000,000 may earn more than depositing ₹100,000 at the same bank.
Interest can be paid to you monthly, quarterly, half-yearly, or at the end of the term. If you choose to receive it during the term, you get smaller payments spread out. If you choose to receive it at maturity, the full amount compounds (meaning you earn interest on your interest) and you get one large payment at the end. Compounding makes your final amount larger, but you do not see any money until the term ends.
To calculate what you will receive: if you deposit ₹100,000 at 7% per year for two years with annual compounding, you will have ₹114,490 at maturity. The ₹14,490 is your earnings. If the same deposit earned simple interest instead (no compounding), you would have ₹114,000. The difference grows larger with longer terms and higher rates.
Penalties for Withdrawing Money Early
If you need your money before the term ends, you can withdraw it, but the bank will charge a penalty. The penalty is usually a reduction in the interest rate you receive — for example, the bank might pay you 2% instead of the promised 7%. Some banks charge a flat fee instead. A few banks allow penalty-free withdrawal after a certain point (such as after one year of a five-year term), but this is uncommon and must be stated in the account terms when you open it.
The penalty can be severe enough that you earn less than you would have in a regular savings account. Before opening a fixed deposit, think honestly about whether you will need the money during the term. If you might need it, a savings account or a money market account may be safer, even though the interest rate is lower.
Some banks offer "flexi deposits" or "sweep accounts" that let you withdraw part of the money without losing all the interest, but these are less common and the interest rate is usually lower than a standard fixed deposit.
Tax on Fixed Deposit Interest
Interest earned on a fixed deposit is taxable income. If you earn ₹50,000 in interest during a financial year, that ₹50,000 must be reported on your income tax return. The tax you owe depends on your total income and your tax bracket — the higher your income, the higher the tax rate on the interest.
Banks automatically deduct tax at source (called TDS, or Tax Deducted at Source) if your interest earnings exceed ₹40,000 in a financial year (or ₹50,000 if you are over 60). The bank withholds the tax and sends it to the government, and you receive the interest minus the tax. You can still claim a refund when you file your tax return if too much was withheld.
To avoid TDS, you can submit Form 15G (if your total income is below the tax threshold) or Form 15H (if you are over 60 and your income is below the threshold) to the bank. These forms tell the bank not to withhold tax because your total income will not be taxable. You must submit the form before the interest is credited.
Deposit Insurance and What Happens If the Bank Fails
Fixed deposits held at banks licensed by the Reserve Bank of India (RBI) are protected by the Deposit Insurance and Credit may provide Corporation (DICGC). If the bank fails, the DICGC will repay you up to ₹500,000 per depositor per bank. This means if you have ₹600,000 in fixed deposits at one bank, only ₹500,000 is insured and you lose ₹100,000.
If you have money at multiple banks, each bank's deposits are insured separately up to ₹500,000. So ₹500,000 at Bank A and ₹500,000 at Bank B are both fully insured. The insurance covers the principal (the money you deposited) plus any interest earned up to the date of the bank's failure.
Fixed deposits at post offices are insured under a different scheme with similar limits. NBFCs (non-banking financial companies) are not covered by DICGC insurance, so deposits with them carry more risk. Before opening an FD with an NBFC, check whether they are regulated by the RBI and what protections exist.
How to Open a Fixed Deposit
To open a fixed deposit, you will need to visit a bank branch or use the bank's online platform if they offer it. You will need to provide your name, address, PAN (Permanent Account Number), and proof of identity and residence. If you already have a savings or current account at the bank, the process is faster because they already have your details.
You then choose the deposit amount, the term (how long to lock the money), and how often you want interest paid. The bank will show you the interest rate that applies to your choices. Once you confirm, the money is transferred from your account to the fixed deposit, and the term begins. You will receive a certificate or confirmation showing the deposit amount, rate, maturity date, and interest payment schedule.
When the term ends, the bank automatically returns your principal and interest to your account. Some banks let you choose to renew the deposit automatically at the new rate; others require you to actively renew or withdraw the money. Check the terms when you open the account so you know what will happen at maturity.
Fixed Deposits Versus Other Savings Options
A fixed deposit pays more interest than a savings account but less than you might earn from stocks or mutual funds. A savings account at most banks pays 2% to 4% per year and lets you withdraw money anytime. A fixed deposit pays 5% to 8% per year (rates vary) but locks your money away. A mutual fund or stock investment might pay 10% to 15% or more over time, but the amount can go down as well as up.
Fixed deposits make sense if you have money you will not need for several years and want to know exactly how much you will have at the end. They are less useful if you might need the money soon or if you are saving for a goal more than ten years away, because inflation will reduce the real value of your money over that long period.
Some people use a "ladder" strategy: they open multiple fixed deposits with different maturity dates (one maturing in one year, one in two years, one in three years, and so on). This way, part of their money becomes available each year, and they can reinvest it or use it as needed, while still earning the higher fixed deposit rate on the rest.
Frequently Asked Questions
Can I withdraw money from a fixed deposit before it matures?
Yes, but you will pay a penalty. The bank usually reduces the interest rate you receive — sometimes to as low as the savings account rate — which can mean you earn almost nothing on your money. Some banks allow penalty-free withdrawal after a certain period (such as after one year), but you must check the specific terms when you open the account.
What happens to my fixed deposit if the bank merges with another bank?
Your deposit transfers to the new bank and the terms remain the same. The DICGC insurance limit applies to the merged entity, so if you have deposits at both banks before the merger, they may now be counted together for insurance purposes. Contact the bank for details about how the merger affects your account.
Can I use a fixed deposit as collateral for a loan?
Yes. Many banks will lend you money against your fixed deposit at an interest rate slightly higher than the deposit rate. For example, if your FD earns 7%, the bank might lend you money at 9%. This lets you access cash without breaking the deposit, though you pay interest on the loan.
Is the interest rate the same for everyone?
No. Interest rates vary by bank, deposit amount, and term length. Two banks might offer different rates on the same term. Within one bank, a ₹1,000,000 deposit might earn more than a ₹100,000 deposit. Rates also change over time as economic conditions shift. Always check the current rate at the time you open the account.
What if I die before the fixed deposit matures?
Your nominee (the person you named when you opened the account) can claim the deposit and receive the principal plus interest earned up to your death. If you did not name a nominee, your heirs will need to go through a legal process to claim the money. Naming a nominee when you open the account makes it easier for your family.
