Post Office PPF Calculator
The Public Provident Fund (PPF) is a government-backed, long-term savings scheme offering a guaranteed, fully tax-free return over a 15-year base term. The Post Office (India Post) is the original home of the PPF and remains one of the most trusted places to hold the account, especially in towns and rural areas where the post-office network reaches further than private banks. The scheme is operated under the National Savings Institute, so the interest rate, contribution limits and tax benefits are exactly the same as a PPF held at any bank — the Post Office simply administers your account. Use this Post Office PPF calculator to project your maturity value and total tax-free interest from your yearly contributions.

Formula
M = P × [((1 + r)ⁿ − 1) ÷ r] × (1 + r)
- M
- Maturity value at the end of the term.
- P
- Yearly contribution (PPF allows up to ₹1.5 lakh per year).
- r
- Annual PPF interest rate ÷ 100 (government-set, same everywhere).
- n
- Number of years invested (minimum 15).
PPF interest compounds annually and the maturity amount is fully tax-free. The government fixes the rate every quarter and it is identical at the Post Office and at every bank; this calculator assumes a fixed yearly contribution.
Worked example
Suppose you invest ₹1,50,000 every year into your Post Office PPF account at the government PPF rate of 7.1% per annum for the full 15-year term.
- Yearly Investment (P)
- ₹1,50,000
- Interest Rate (p.a.)
- 7.1% (government-set)
- Tenure
- 15 years
You invest ₹22,50,000 in total over 15 years. At 7.1% the Post Office PPF account matures to about ₹40,68,209 — meaning roughly ₹18,18,209 of tax-free interest on top of your contributions.

How this Post Office PPF calculator works
Adjust the yearly investment, interest rate and tenure sliders to see your Post Office PPF maturity value and tax-free interest update instantly, with a breakdown of contributions versus interest. The rate is pre-set to the current government PPF rate of 7.1% — update it whenever the government revises the rate. Because PPF compounds annually over a long horizon, the interest portion grows to a large share of the final corpus, which the chart makes clear.
Why hold your PPF at the Post Office
For many savers — particularly outside large cities — the Post Office is the most accessible institution, with a network that reaches where private banks do not. The product itself is identical to a bank PPF: the same government-set rate, the same ₹1.5 lakh annual cap, the same EEE tax treatment and the same 15-year discipline. If your banking later shifts, you can transfer the account to a bank without breaking its continuity. Many investors pair the safety of PPF with market-linked options like a SIP to balance stability and growth, and compare it against an FD or RD for shorter-term savings.
Tips for Post Office PPF investors
- Deposit before the 5th of the month — interest is reckoned on the lowest balance between the 5th and month-end, so early deposits earn more.
- Invest early in the financial year so each contribution earns a full year of interest.
- Use the IPPB app or standing instruction so contributions are timely and the account never lapses.
- Contribute the ₹1.5 lakh maximum if you can, to build the largest tax-free corpus and use your full Section 80C limit.
- Extend in 5-year blocks after maturity to keep the tax-free compounding going.

Frequently asked questions.
How do I open a PPF account at the Post Office?
Visit any Post Office offering savings services with your PAN, Aadhaar, a photograph and the opening deposit, and fill in Form A. Many post offices now also support PPF through the India Post Payments Bank (IPPB) app. The account is opened in your own name, or as a guardian for a minor.
Is the Post Office PPF rate different from a bank PPF?
No. The PPF interest rate is set by the central government and revised every quarter, and it is the same whether your account is at a Post Office or any bank. The Post Office only administers the account; it does not set the rate. This calculator lets you enter the current rate so your projection stays accurate.
Is Post Office PPF tax-free?
Yes. PPF carries EEE (exempt-exempt-exempt) status: contributions qualify for deduction under Section 80C, the interest is tax-free, and the maturity amount is tax-free. This applies to a Post Office PPF account exactly as it does at a bank.
Can I transfer my Post Office PPF to a bank later?
Yes. A PPF account can be transferred between a Post Office and a bank (or between banks) without losing its history, balance or maturity date — the account simply continues at the new institution. The transfer is treated as continuous, so your compounding is unaffected.
What are the Post Office PPF limits and tenure?
You can invest between ₹500 and ₹1,50,000 per financial year across all your PPF accounts combined. The base term is 15 years, extendable in 5-year blocks thereafter. Loans are available between the 3rd and 6th years and partial withdrawals from the 7th year. Use the tenure slider to see how extending the term grows your corpus.
