How PPF maturity is estimated
PPF (Public Provident Fund) is a long-term, government-backed savings scheme in India. Most accounts have a 15-year lock-in; contributions earn interest that is compounded annually in this planning model.
Each year we add your yearly deposit to the balance, apply the annual rate to the full balance, and credit interest—similar to many online PPF estimators used for rough planning.
Real PPF interest uses rules tied to monthly balances and government-notified rates. Always confirm the current rate and ₹1.5 lakh per financial year deposit cap with official sources. Compare with FD, SIP, or lumpsum tools for other goals.
How to use this calculator
- Enter yearly PPF deposit (up to ₹1.5 lakh per financial year is the usual cap).
- Set the annual interest rate (use the latest government-notified PPF rate for planning).
- Choose tenure in years—15 is the default minimum lock-in period.
- Add opening balance only if you already have corpus in the account.
- Review maturity amount, interest, and the year-wise table.
Worked examples
Sample numbers you can try in the calculator above. Your lender's quote may differ slightly.
₹1.5 lakh/year for 15 years at 7.1%
Maxing the common annual limit for the full lock-in builds a large tax-free-style savings corpus in the model.
₹1,50,000 yearly · 7.1% · 15 years
Maturity: Maturity roughly ₹40+ lakh (estimate)
₹50,000/year for 15 years
Smaller yearly deposits still benefit from 15 years of compounding.
₹50,000 yearly · 7.1% · 15 years
Maturity: Lower corpus, same tenure
20-year extension
After 15 years, accounts can be extended in blocks—model longer horizons if you plan to continue.
₹1,00,000/year · 7% · 20 years
Maturity: Longer tenure increases maturity
Existing balance
Use opening balance for money already in the account before future yearly investments.
₹2,00,000 opening + ₹1 lakh/year
Maturity: Opening balance grows with new deposits
Frequently asked questions about the PPF calculator
What is PPF in India?
Public Provident Fund is a long-term savings scheme offered via banks and post offices, backed by the Government of India. It is popular for retirement-style savings with tax benefits under current law (confirm with a tax adviser).
What is the maximum PPF deposit per year?
The usual limit is ₹1.5 lakh per financial year across your PPF accounts combined. This calculator lets you enter any amount for planning, but do not rely on numbers above the legal cap.
How is PPF interest calculated?
Actual PPF interest follows government rules on monthly balances. This tool uses a simplified yearly model: add your annual deposit, then apply one year of interest to the balance—good for estimates, not exact bank statements.
Is PPF locked for 15 years?
New PPF accounts generally have a 15-year maturity from the end of the financial year of opening. Partial withdrawals and extensions are allowed under rules after that period.
PPF vs FD—which is better?
PPF is long-term with tax benefits and government-notified rates; FDs are flexible bank deposits with chosen tenure. Use this PPF calculator for long horizons and the FD calculator for shorter bank FD quotes.
