Post Office Time Deposit Calculator
Calculate Annual Payouts & check the "Smart RD Reinvestment" Strategy.
Why do this? Unlike Bank FDs, Post Office FDs do not offer a cumulative option. Your interest sits idle in a savings account (4%).
By reinvesting this payout into a 5-Year RD (6.7%), you earn interest-on-interest manually.
Tax Rule: Interest income is fully taxable. TDS (10%) is deducted if interest exceeds ₹40,000/yr (₹50k for Seniors).

Why India Trusts the “Post Office” Above All
In a world of volatile stock markets and private banks that occasionally make headlines for the wrong reasons, the Indian Post Office remains a fortress of financial safety.
When you invest in a Post Office Fixed Deposit (officially known as National Savings Time Deposit or POTD), you aren’t just lending money to a bank; you are lending it to the Government of India. It comes with a Sovereign Guarantee, meaning your money is 100% safe, regardless of economic conditions.
However, Post Office FDs work differently from Bank FDs. They don’t just “compound” your money quietly in the background. They pay out interest annually. If you don’t know how to handle these payouts, you might be losing money to inflation.
The FinMinutes Post Office FD Calculator isn’t just a calculator; it’s a Strategy Tool. It helps you calculate your guaranteed returns and shows you how to “create” compounding using the smart RD Reinvestment Strategy.
The “Hidden” Problem with Post Office FDs
Most investors assume that if they invest ₹5 Lakhs for 5 years at 7.5%, they will get a big lump sum at the end. This is wrong. Unlike Bank FDs, which offer a “Cumulative” option (where interest is added back to the principal), Post Office Time Deposits are strictly Non-Cumulative.
How it actually works:
- Interest Calculation: Interest is calculated quarterly.
- Interest Payout: The interest is paid out annually to your savings account.
- The Trap: If you leave this annual interest in your savings account, it earns a measly 4%. Your high-return investment (7.5%) essentially “leaks” value every year.
The Solution: The “Daisy Chain” Strategy
Our tool includes a unique “Reinvest in RD” toggle.
- Step 1: You open a 5-Year Time Deposit.
- Step 2: You instruct the Post Office to credit annual interest to your Savings Account.
- Step 3: Set a “Standing Instruction” to auto-debit the amount into a 5-Year Recurring Deposit (RD).
Result: Your 7.5% interest starts earning an additional 6.7% (RD Rate) instead of idling at 4%. This is how you beat the system.

4. Analyse the Schedule
Scroll down to the “Yearly Breakdown” table. It shows you exactly how much money hits your account every year and whether it’s idling or growing.
Current Post Office FD Interest Rates
Interest rates for Small Savings Schemes are reviewed and announced by the Ministry of Finance every quarter. It is crucial to lock in high rates when they are available, as your rate is fixed for the entire tenure once you open the account.
| Tenure | Interest Rate (p.a.) | Compounding Freq. | Payout Freq. |
| 1 Year | 6.9% | Quarterly | Annual |
| 2 Year | 7.0% | Quarterly | Annual |
| 3 Year | 7.1% | Quarterly | Annual |
| 5 Year | 7.5% | Quarterly | Annual |
Note: The 5-Year TD is the only tenure eligible for Tax Benefits under Section 80C.
Post Office FD vs. Bank FD: The Showdown
Should you go to your local SBI/HDFC branch or the nearest Post Office? Here is the honest comparison.
1. Safety (The Sovereign Edge)
- Bank FD: Insured by DICGC only up to ₹5 Lakhs. If you have ₹50 Lakhs in a bank and it collapses, only ₹5 Lakhs is guaranteed.
- Post Office FD: Sovereign Guarantee on 100% of the amount. Whether you invest ₹1 Lakh or ₹1 Crore, the Government of India guarantees every rupee.
2. Interest Payout Mechanism
- Bank FD: Flexible. You can choose Monthly, Quarterly, or Cumulative (On Maturity) payout.
- Post Office FD: Rigid. Interest is payable annually. No cumulative option exists. This is why our Strategy Tool is essential.
3. Tax Benefits (Section 80C)
- Bank FD: Only specific “5-Year Tax Saver FDs” qualify. You cannot break these before 5 years.
- Post Office FD: The 5-Year Time Deposit qualifies for Section 80C deduction (up to ₹1.5 Lakhs/year).
Important Rules You Must Know about POFD
Premature Withdrawal
Did you run into an emergency? The Post Office allows you to close the account early, but with penalties:
- Before 6 Months: Withdrawal not allowed.
- 6 – 12 Months: You will only get Savings Account Interest Rate (4%), not the FD rate.
- After 1 Year: Allowed, but the interest rate will be reduced by 2% from the contracted rate.
Extension of Account
If your FD matures but you don’t want to withdraw, you can extend it within a specific window:
- 1 Year FD: Extend within 6 months of maturity.
- 2 Year FD: Extend within 12 months.
- 3/5 Year FD: Extend within 18 months.
- Benefit: You lock in the interest rate prevailing at the time of extension.
TDS (Tax Deducted at Source)
Unlike banks, the Post Office does NOT deduct TDS on Time Deposit interest.
- Warning: This does not mean the interest is tax-free!
- The interest earned is fully taxable as per your income slab. You must manually add it to your income while filing your ITR under “Income from Other Sources.”
Post Office Fixed Deposit Calculator: FAQs
Can I open a Post Office FD online?
Yes. If you have an active Post Office Savings Account with Net Banking or Mobile Banking enabled, you can open and close Time Deposits online without visiting the branch.
Is the interest rate fixed for the entire 5 years?
Yes. The rate applicable on the date of opening applies for the entire tenure. Future rate cuts by the government will not affect your existing deposit.
How is the “RD Reinvestment” better than a Bank Cumulative FD?
Mathematically, a Bank Cumulative FD might offer slightly higher yields due to quarterly compounding within the account. However, the Post Office RD strategy offers unmatched safety for a large corpus (>₹5 Lakhs) where bank insurance limits (DICGC) fall short.
Can Senior Citizens get extra rates?
No. Unlike banks, the Post Office Time Deposit does not offer extra rates for Senior Citizens. Seniors should instead look at the SCSS (Senior Citizen Savings Scheme), which currently offers significantly higher returns (8.2%).
What happens if I don’t withdraw the annual interest in a post office FD?
It sits in your Post Office Savings Account. If you don’t have a linked savings account, it stands as a “sundry” balance and earns zero interest. Always link a savings account.
Conclusion
The Post Office Fixed Deposit is the bedrock of a secure Indian portfolio. It offers decent returns with zero risk. However, its “annual payout” nature can act as a drag on wealth creation if you aren’t careful.
Don’t let your interest sit idle. Use the FinMinutes Post Office FD Calculator, toggle on the Smart Strategy, and see exactly how much richer you can be by making one simple change to your investment habits. Start Calculating Now! 📮
