The Post Office FD scheme is a savings option for people who want predictable returns without following the stock market. You deposit money once, choose a fixed period and earn interest under government small savings rules.
Officially called the National Savings Time Deposit Account, it is commonly known as a Post Office Fixed Deposit or Post Office TD. You can choose a one-year, two-year, three-year or five-year account, depending on when you need your money.
However, the interest rate is only one part of the decision. Annual payouts, tax treatment and early withdrawal rules also affect how useful this investment will be for you. Here is a simple guide to understanding the Post Office FD Scheme before opening an account.

What Is the Post Office FD Scheme?
A Post Office FD allows you to invest a lump sum for a selected tenure. It is a Government of India small savings scheme available through post offices.
Unlike a recurring deposit, you do not make monthly contributions to the same account. You place the deposit when opening it. If you want to invest another amount later, you can open another eligible account.
The interest rate applicable when the account is opened generally remains fixed until maturity. Later changes in rates for new deposits do not change the contracted rate on your existing deposit.
Post Office FD Scheme Interest Rates
The published Post Office Time Deposit rates are:
| Deposit tenure | Annual interest rate |
|---|---|
| 1 year | 6.9% |
| 2 years | 7.0% |
| 3 years | 7.1% |
| 5 years | 7.5% |
The government reviews small savings rates quarterly. Confirm the applicable rate when opening your account, especially if you are reading this guide after a new quarter begins.
The five-year option offers the highest rate among these tenures, but it also requires a longer commitment. A slightly lower rate can be more practical if your money is needed sooner.
Minimum Deposit and Investment Limit
The minimum deposit is ₹1,000. Deposits above this amount must be in multiples of ₹100. There is no prescribed maximum investment limit under the scheme.
For example, you can open an account with ₹1,000, ₹5,000, ₹25,000 or ₹1 lakh, depending on your budget.
The absence of a maximum limit does not mean you should put all your savings into one deposit. Keep enough accessible money for regular expenses and unexpected needs before choosing a fixed tenure.
Who Can Open a Post Office FD?
Eligible account arrangements include:
- A single account opened by an adult.
- A joint account with up to three adults.
- An account opened by a guardian for a minor.
- An account opened by a guardian for a person of unsound mind.
- An account opened by a minor aged ten or above in their own name.
The account must meet the applicable residency and identification rules. For a child’s account, ask the post office about documentation and the formalities required when the child becomes an adult.
How Is Post Office FD Interest Calculated?
Interest is calculated with quarterly compounding but is payable annually. These two features are often confused.
Quarterly compounding determines the annual interest amount. It does not mean the annual payout automatically stays invested in the same TD for the entire tenure. Interest that becomes payable but remains unwithdrawn does not earn additional TD interest.
For an illustrative annual payout, use:
Annual interest = Deposit × [(1 + annual rate ÷ 4)⁴ − 1]
Enter the rate as a decimal. At 7.5%, that means using 0.075. Actual credited amounts follow the scheme’s calculation and rounding rules.
Example: ₹1 Lakh in a Five-Year Post Office FD
At an annual rate of 7.5%, a ₹1 lakh deposit generates approximately ₹7,714 in annual interest.
| Component | Approximate amount |
|---|---|
| Initial deposit | ₹1,00,000 |
| Annual interest payout | ₹7,714 |
| Total interest over five years | ₹38,570 |
| Principal returned at maturity | ₹1,00,000 |
| Total receipts across the full term | ₹1,38,570 |
These figures are before tax and rounded for explanation. The total receipts include interest paid during the five years; they are not a single maturity cheque. Returns from separately reinvesting those payouts are excluded.
Main Benefits of the Post Office FD Scheme
Government backing: The scheme suits savers who value the security of a government small savings product.
Predictable income: Knowing the rate and annual payout helps you plan future spending without depending on market movements.
Choice of tenure: Four durations allow you to match the deposit with a planned expense, such as an education payment or a future purchase.
Accessible starting amount: A ₹1,000 minimum makes it possible to begin with a modest sum.
Practical account facilities: Nomination and account transfer facilities can help with account management. Keep nominee information accurate and tell a trusted family member where your deposit records are stored.
Post Office FD Tax Benefits
The five-year Post Office Time Deposit qualifies for the investment deduction commonly referred to as Section 80C, subject to the applicable tax law, eligible tax regime and overall limit. Under the old-regime framework, the combined limit is ₹1.5 lakh for qualifying investments and payments.
One-year, two-year and three-year deposits do not qualify for this particular five-year TD deduction. The standard new tax regime does not provide the same deduction.
Interest is generally taxable; a deduction on the deposit does not make its interest tax-free. Any separate relief depends on your eligibility. Check the provisions applicable to your tax year before claiming a deduction, especially because tax legislation and section numbering can change.
Premature Withdrawal Rules
Early closure can reduce your return substantially. The rules depend on the tenure and, for five-year accounts, the opening date.
For one-year, two-year and three-year accounts, withdrawal is not permitted during the first six months. Closure after six months but before one year generally attracts the Post Office Savings Account rate. Two-year and three-year accounts closed after one year are subject to reduced-interest calculations.
Five-year accounts opened under the rules effective from 10 November 2023 cannot ordinarily be closed before four years. Closure after four years but before maturity attracts the Post Office Savings Account rate under those rules. Previously paid excess interest is adjusted.
Older five-year accounts can follow different provisions. Ask for a closure calculation for your specific account before submitting a request.
Documents Required to Open an Account
Usually, you should be ready with:
- A completed account opening form and deposit slip.
- Aadhaar and the required identity and address documentation.
- PAN or the permitted alternative declaration, where applicable.
- Recent photographs.
- Mobile number and nominee details.
- Relevant guardian and minor documents, if needed.
Carry originals for verification along with the required copies. The post office can confirm any additional documents for your account type.
How to Open a Post Office FD
- Visit a post office offering savings account services.
- Request the Time Deposit account opening form.
- Select your deposit amount and tenure.
- Fill in personal, joint-holder and nominee details carefully.
- Submit the completed paperwork and identification documents.
- Make the deposit through an accepted payment method.
- Check the account record for the amount, tenure, rate and maturity date.
Ask how annual interest will be credited and whether your eligible account can use India Post’s online banking facilities. Keep the acknowledgement and account details safely for future reference.
How to Choose the Right Tenure
Start with the date when you expect to need the money. If an expense is due next year, a five-year deposit creates an unnecessary mismatch, even if its advertised rate is higher.
For separate goals, consider separate deposits. One could mature for a near-term expense while another remains invested for longer. This makes planning clearer and may reduce the need to close a large deposit early.
Also decide what you will do with annual interest. Spending it provides income; reinvesting it elsewhere may help savings grow. Either way, make that choice deliberately rather than assuming the TD automatically reinvests every payout.
Frequently Asked Questions
Is Post Office FD interest paid monthly?
No. Time Deposit interest is payable annually. The Post Office Monthly Income Scheme is a different product designed around monthly payouts.
Can I invest ₹5 lakh in a Post Office FD?
Yes. The scheme has no prescribed maximum deposit limit, although identification, payment and reporting requirements still apply.
Do senior citizens get a higher Post Office FD rate?
There is no separate senior-citizen bonus rate within the standard TD scheme. The Senior Citizens Savings Scheme is a separate product with its own eligibility conditions.
Will my money double in five years?
No. At the rates shown above, a five-year TD does not double your deposit. Be cautious with examples that incorrectly assume automatic reinvestment of annual interest.
What should I check before investing?
Confirm the opening-date rate, interest credit instructions, withdrawal restrictions and tax treatment. Choose a tenure that fits your goal and keep emergency money accessible outside the deposit.
