PNB PPF Interest Calculator 2024
Calculate your Public Provident Fund maturity amount with Punjab National Bank’s current interest rates
Introduction & Importance of PNB PPF Calculator
The Public Provident Fund (PPF) offered by Punjab National Bank is one of India’s most popular long-term savings schemes, combining attractive interest rates with significant tax benefits under Section 80C of the Income Tax Act. The PNB PPF interest calculator is an essential financial tool that helps investors:
- Project their maturity amount based on different investment scenarios
- Understand the power of compounding over the 15-year lock-in period
- Compare returns with other investment options like FDs or mutual funds
- Plan their annual investments to maximize tax savings (up to ₹1.5 lakh per year)
- Make informed decisions about extending their PPF account beyond 15 years
According to the Reserve Bank of India, PPF accounts have consistently delivered inflation-beating returns, making them a cornerstone of conservative investment portfolios. The current interest rate of 7.1% (as of Q2 2024) is compounded annually, which significantly boosts long-term returns compared to simple interest instruments.

Interactive PPF Calculator FAQs
What is the current PNB PPF interest rate for 2024?
The current PNB PPF interest rate is 7.1% per annum (as of April 2024). This rate is compounded annually and is set by the Government of India on a quarterly basis. The rate has remained stable at 7.1% since Q2 2020, though it was as high as 8.7% in 2015-16.
You can verify the current rate on the official PNB website or the Ministry of Finance notifications.
Can I open multiple PPF accounts in PNB?
No, you cannot open multiple PPF accounts in your own name under normal circumstances. The PPF rules strictly permit only one account per individual, except:
- You can open a second account on behalf of a minor child
- If you’re a guardian, you can open accounts for multiple minors
- In case of account transfer from another bank to PNB
Violations can lead to the closure of additional accounts without interest benefits. The maximum combined deposit across all accounts (including minor accounts where you’re guardian) cannot exceed ₹1.5 lakh per financial year.
How is PPF interest calculated monthly in PNB?
While PPF interest is compounded annually, it’s calculated monthly based on the lowest balance between the 5th and last day of each month. Here’s how it works:
- PNB checks your balance on the 5th of each month (or next working day)
- Also checks the balance at month-end
- Uses the lower of these two balances for interest calculation
- Interest for all months is summed and credited on 31st March
Example: If you deposit ₹10,000 on:
- 4th March: Gets full month’s interest
- 6th March: Gets interest from 6th-31st only
- 25th March: Gets minimal interest
This is why depositing before the 5th of each month maximizes your returns.
What happens if I don’t deposit the minimum ₹500 in a year?
If you fail to deposit the minimum ₹500 in any financial year, your PNB PPF account will become inactive. Here’s what happens:
- You cannot make further deposits until reactivated
- No interest is paid for the years the account remains inactive
- To reactivate, you must pay:
- ₹500 for the year of default
- ₹50 as penalty for each year of default
- The account can be reactivated within the 15-year tenure
- If not reactivated, the account earns no interest but remains open
Important: The account doesn’t close automatically – it just stops earning interest until reactivated. You can still withdraw the balance after maturity.
Can I withdraw money from my PNB PPF account before 15 years?
Yes, partial withdrawals are allowed from the 7th financial year onwards, subject to conditions:
- Timing: Only one withdrawal per financial year
- Amount: Maximum of 50% of the balance at the end of the 4th year preceding the withdrawal year
- Purpose: No restrictions – can be used for any financial need
- Process: Submit Form C with passbook at your PNB branch
Example: If you opened the account in 2020-21:
- First eligible withdrawal: 2026-27 (7th year)
- Maximum amount: 50% of balance as on 31.03.2023
Important Notes:
- Withdrawals don’t affect your loan eligibility
- The withdrawn amount cannot be redeposited
- Interest continues on the remaining balance
How does PNB PPF compare with SBI PPF?
There is no difference between PNB PPF and SBI PPF in terms of:
- Interest rate (7.1% for both, set by government)
- Tax benefits (both qualify for Section 80C)
- Tenure (15 years minimum for both)
- Deposit limits (₹500-₹1.5 lakh per year)
- Withdrawal and loan rules
The only differences are in:
| Feature | PNB PPF | SBI PPF |
|---|---|---|
| Account Opening | Online + Branch | Online + Branch |
| Mobile App | PNB One | SBI YONO |
| Branch Network | 10,000+ branches | 22,000+ branches |
| Customer Service | 1800 180 2222 | 1800 11 2211 |
| Additional Services | Linked to PNB savings account | Linked to SBI savings account |
Recommendation: Choose based on which bank you already have a relationship with, as the core PPF features are identical. Both are equally safe as government-backed schemes.
What happens to my PNB PPF account after 15 years?
After the initial 15-year lock-in period, you have three options with your PNB PPF account:
-
Close the Account:
- Withdraw the entire maturity amount
- No tax on the withdrawal
- Account becomes inactive
-
Extend Without Contributions:
- Account remains open without new deposits
- Continues to earn interest at prevailing rates
- Can make one withdrawal per year
- No time limit – can extend indefinitely
-
Extend With Contributions:
- Can continue depositing ₹500-₹1.5 lakh annually
- Extension in blocks of 5 years
- Can make one withdrawal per year (from extended period)
- Must submit Form H for extension
Key Points:
- If you don’t take any action, the account is automatically extended without contributions
- You can switch between options later (e.g., start contributing after initial extension)
- Extended accounts continue to enjoy tax benefits
- Interest remains tax-free even after maturity
Most financial advisors recommend extending the account (with or without contributions) to continue enjoying the tax-free returns, especially if you’ve already built a substantial corpus.
