Public Provident Fund (PPF) Calculator
Estimate your PPF maturity amount, total investment, and interest earned using annual contributions.
What is a Public Provident Fund (PPF)?
Public Provident Fund (PPF) is one of India’s most trusted long-term savings instruments. It is backed by the Government of India, offers tax benefits under Section 80C, and helps investors build disciplined wealth with low risk. A PPF account has a 15-year lock-in period, with options to extend in blocks of 5 years.
Why use this public provident fund india calculator?
A PPF account grows through annual contributions plus compound interest. Even small yearly deposits can grow significantly over time. This calculator helps you:
- Estimate maturity value before opening or extending your account.
- Compare contribution levels (for example ₹50,000 vs ₹1,50,000 per year).
- Understand how tenure and deposit timing affect total returns.
- Plan tax-saving investments in a realistic way.
How the calculator works
The tool uses annual compounding for a practical projection. You enter your annual contribution, expected interest rate, and number of years. Then it computes:
- Total Invested: Annual contribution × number of years
- Interest Earned: Maturity amount − total invested
- Maturity Amount: Final projected balance at the end of tenure
If you choose deposit at the beginning of each year, your money gets one extra year of growth compared with end-of-year deposits.
Current key PPF rules (quick summary)
1) Minimum and maximum investment
You must invest at least ₹500 in a financial year to keep the account active. The maximum eligible contribution is ₹1,50,000 per financial year.
2) Lock-in and extension
The base tenure is 15 years. After maturity, you can extend your account in 5-year blocks, with or without fresh contributions.
3) Tax benefits
PPF generally falls under the EEE (Exempt-Exempt-Exempt) category:
- Contribution eligible for deduction (subject to 80C limits),
- Interest earned is tax-free,
- Maturity amount is tax-free.
4) Loan and partial withdrawal
Loans and partial withdrawals are allowed under specific rules after certain years. Always verify latest guidelines from your bank/post office before planning withdrawals.
Example scenario
Suppose you invest ₹1,50,000 every year for 15 years at 7.1% annual interest. The calculator will show the projected maturity amount and break down how much of it is your own contribution versus interest gains. Try changing the tenure to 20 or 25 years to see the impact of compounding.
Tips to maximize your PPF returns
- Invest early in the financial year to maximize interest accrual.
- Contribute consistently instead of skipping years.
- Use PPF as the debt-stability part of your long-term portfolio.
- Consider extension blocks after 15 years for stronger compounding.
- Review annual policy updates and interest rate revisions.
PPF vs other options (at a glance)
Compared with market-linked instruments, PPF offers stability and tax efficiency, but lower flexibility due to lock-in. It is often ideal for conservative long-term goals such as retirement corpus balance, child education safety bucket, or predictable wealth accumulation.
Frequently asked questions
Is this calculator exact?
It is a strong estimate. Actual credit can differ slightly due to monthly balance method and periodic interest-rate changes by the government.
Can I invest monthly in PPF?
Yes, contributions can be made in installments (within annual cap). This tool simplifies that into annual totals for easy planning.
Can I extend my PPF account beyond 15 years?
Yes, in 5-year blocks. Use the tenure field to model longer periods like 20, 25, or 30 years.
