How This Calculator Works
Enter your current PPF balance, monthly contribution, the PPF rate, and the tenure (the standard PPF term is 15 years, extendable in blocks of 5). The calculator compounds the balance and shows the estimated maturity value and total interest. PPF enjoys EEE tax status — contributions, interest, and maturity are all tax-exempt.
The Formula
Future Value with Regular Contributions
P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
A ₹50,000 balance plus ₹10,000 a month for 15 years at 7.1% grows to roughly ₹33.4 lakh (about ₹3,341,911) — with around ₹14.9 lakh of that being tax-free interest. The PPF (Public Provident Fund) is a government-backed long-term savings scheme with a 15-year lock-in, a fixed rate revised quarterly by the government, and — crucially — EEE (Exempt-Exempt-Exempt) tax treatment: contributions are deductible under Section 80C, the interest is tax-free, and the maturity amount is tax-free.
Key Insight
PPF is a cornerstone of conservative, tax-efficient saving in India, and its appeal rests on safety plus the rare EEE tax status. Key features: it's backed by the Government of India (effectively risk-free), pays a fixed rate set and revised quarterly by the government (so the rate can change over the 15-year term), and has a 15-year maturity that can be extended indefinitely in 5-year blocks. The tax treatment is its biggest draw — Exempt-Exempt-Exempt: deposits qualify for deduction under Section 80C (up to the ₹1.5 lakh annual limit, shared with other 80C investments), the interest earned is fully tax-free, and the maturity proceeds are tax-free — a combination few instruments offer. Contribution rules: a minimum yearly deposit keeps the account active, and the annual maximum is ₹1.5 lakh; deposits can be lump-sum or in instalments. A nuance this simple monthly-compounding estimate glosses over: PPF interest is actually calculated on the minimum balance between the 5th and last day of each month and credited annually, so to maximise interest, deposit before the 5th of the month. Partial withdrawals are allowed from year 7, and loans against the balance from years 3–6. For long-horizon, risk-averse goals (retirement, a child's future), PPF's guaranteed, tax-free compounding is hard to beat among safe instruments — though equity (e.g. ELSS or index funds) may outperform over very long periods at higher risk. This is an estimate; confirm the current quarterly rate and rules, as the government revises them.
Frequently Asked Questions
How is PPF maturity calculated?
Your balance and contributions compound at the PPF rate. A ₹50,000 balance plus ₹10,000/month for 15 years at 7.1% grows to roughly ₹33.4 lakh. (PPF interest is officially calculated on the minimum monthly balance and compounded annually, so this monthly-compounding figure is a close estimate.)
Is PPF tax-free?
Yes — PPF has EEE (Exempt-Exempt-Exempt) status: contributions are deductible under Section 80C (within the ₹1.5 lakh annual limit), the interest is fully tax-free, and the maturity amount is tax-free. This rare triple exemption is a major reason for PPF's popularity.
What is the PPF tenure and contribution limit?
The standard tenure is 15 years, extendable in 5-year blocks. The annual contribution limit is ₹1.5 lakh (about ₹12,500/month), with a small minimum yearly deposit required to keep the account active. Deposits can be lump-sum or in instalments through the year.
Is the PPF interest rate fixed?
It's a fixed, government-backed rate, but the government reviews and can revise it quarterly — so the rate can change over your 15-year term (recently around 7.1%). It's not market-linked, which makes PPF safe and predictable but means the rate isn't guaranteed for the full tenure.
When can I withdraw from PPF?
PPF has a 15-year lock-in, but partial withdrawals are allowed from the 7th year, and loans against the balance are available from years 3 to 6. At maturity you can withdraw fully, extend with or without further contributions, or roll into a new 5-year block. To maximise interest, deposit before the 5th of each month.

Methodology & Review
The future value compounds a starting balance and a fixed monthly contribution at the annual rate, compounded monthly for simplicity. It assumes deposits at month end and a constant rate; actual PPF interest is calculated on the minimum monthly balance and compounded annually, and the government can revise the rate quarterly, so this is an estimate.
