PPF Calculator

What This PPF Calculator Does

The Public Provident Fund (PPF) is a long-term, government-backed savings scheme with a 15-year lock-in, a government-notified interest rate (revised quarterly), and tax-free interest under current rules. This calculator projects your PPF maturity value based on your annual contribution and the interest rate.

The Formula

Each year, your contribution is added to the running balance, and the entire balance then earns a year of compound interest: balance = (balance + annual contribution) × (1 + rate), repeated for every year of the tenure. Because PPF compounds annually on the whole balance including prior years' interest, consistent early contributions have an outsized effect on the final maturity value.

How to Use It

Enter your planned annual contribution (up to the current maximum of ₹1,50,000 per financial year), the applicable interest rate, and the tenure - the statutory minimum is 15 years, extendable afterward in blocks of 5. The calculator shows your total contribution, the interest earned, and the projected maturity value.

Why PPF Is Popular for Long-Term, Low-Risk Goals

PPF combines a government guarantee, a rate that has historically stayed well above typical savings account rates, and full tax exemption on both the interest earned and the maturity amount under the current tax regime's applicable rules - a combination few other instruments offer. The trade-off is the long lock-in and a contribution cap, which makes it better suited as one part of a diversified plan rather than your only long-term investment.

Who This Is For

Long-term savers - especially for goals like retirement or a child's future - who want a guaranteed, tax-efficient, low-risk component alongside market-linked investments like mutual fund SIPs.

Quick Example

Contributing ₹1,00,000 every year for the full 15-year PPF tenure at 7.1% builds a maturity value of approximately ₹27,12,139 - roughly ₹12,12,139 of that being interest, entirely tax-free under current rules.
