PPF Calculator: Plan Your Retirement with India's Most Popular Savings Scheme
The Public Provident Fund (PPF) is widely considered the gold standard for long-term, risk-free investing in India. Our PPF Calculator is designed to help you project the growth of your investments over the 15-year mandatory lock-in period. Whether you are investing to save for your child’s education, your own retirement, or simply to save on income tax, this tool provides a clear roadmap for your wealth creation journey.
What makes PPF unique is its EEE status—Exempt (on investment), Exempt (on interest earned), and Exempt (on maturity amount). This means you don't pay a single rupee in tax on the wealth you build within this fund. However, because the interest is compounded annually and the rates are set by the government quarterly, calculating the final maturity manually can be overwhelming. Our calculator does the heavy lifting for you.
In this guide, we'll dive into the rules of PPF, explain the '5th of the month' secret to maximize interest, and provide a 15-year growth table to show you how small monthly saves can turn into a massive tax-free corpus.
What is PPF and Why Should You Invest?
The Public Provident Fund (PPF) is a long-term savings-cum-tax-savings scheme introduced by the National Savings Institute of the Ministry of Finance in 1968. It is specifically designed to provide retirement security to self-employed individuals and those in the unorganized sector, though it is open to all Indian citizens.
The primary draw of PPF is its unmatched safety—it is backed by the Central Government. The interest rate, currently around 7.1% (subject to quarterly change), is usually higher than most bank FDs. Furthermore, the investment is eligible for deduction under Section 80C of the Income Tax Act, up to a limit of ₹1.5 Lakh per year.
With a 15-year lock-in period that can be extended indefinitely in blocks of 5 years, the PPF is a marathon, not a sprint. It uses the power of compounding to turn regular contributions into a multi-generational wealth asset.

The Math Behind PPF Compounding
Compound Interest Formula
F = P [({(1+i)^n} - 1) / i]Where F is maturity, P is annual installment, i is interest rate, and n is number of years.
The Monthly Interest Rule
Minimum balance between the 5th and the last dayInterest is calculated on the lowest balance during this window. If you deposit after the 5th, you lose interest for that month!
