How it works

The Public Provident Fund (PPF) is a government-backed, long-term savings scheme in India with a statutory lock-in of 15 years. It is popular because contributions qualify for a Section 80C deduction, and the interest and maturity amount are entirely tax-free — the coveted EEE (exempt-exempt-exempt) status.

This calculator assumes you contribute a fixed amount each year and that interest is compounded annually on the opening balance plus that year's contribution. The year-by-year table shows how the balance snowballs: closing = (opening + contribution) × (1 + rate/100). The current rate defaults to 7.1%, but you can edit it. The annual contribution ceiling is ₹1.5 lakh.

Figures are estimates. The PPF interest rate is set by the government and revised every quarter, so a long projection assumes the rate stays constant, which it may not. All maths runs privately in your browser.

Examples

₹1,50,000/year for 15 years at 7.1% → invested ₹22.5 lakh, maturity ≈ ₹40.68 lakh.
₹50,000/year for 15 years at 7.1% → maturity ≈ ₹13.56 lakh.
Extend the tenure to 20 years (via a 5-year extension) to see the tax-free corpus grow further.

RiskGovernment-backed — capital is secure

Because PPF interest is compounded annually and the maturity is fully tax-free, contributing early in the financial year (before the 5th of the month) maximises the interest credited. The year-by-year table above shows how the balance builds toward maturity.

Frequently asked questions

What is the current PPF interest rate?
It is set by the government and revised quarterly. The tool defaults to 7.1% but you can change it to match the latest notified rate.
Is PPF interest taxable?
No. PPF enjoys EEE status — contributions are deductible under Section 80C, and both the interest and the maturity amount are tax-free.
What is the maximum I can invest?
The annual deposit limit is ₹1.5 lakh across all your PPF accounts, with a minimum of ₹500 per year to keep the account active.
Can I extend a PPF account beyond 15 years?
Yes, in blocks of 5 years, with or without further contributions. Increase the tenure in the tool to model an extension.
Does the tool model quarterly rate changes?
No. It assumes a constant rate for the whole tenure. Because the government revises the rate quarterly, treat the maturity value as an estimate.
What is the current PPF interest rate?
The PPF interest rate is 7.1% per annum (compounded annually) and has been held at that level across recent quarters. The government reviews small-savings rates every quarter, so it can change — this calculator lets you edit the rate to match the latest figure.
How long is the PPF lock-in period?
A PPF account matures in 15 years from the end of the financial year in which it was opened. After that you can extend it in blocks of 5 years, with or without further contributions. Partial withdrawals are allowed from the 7th year, subject to limits.
How much can I invest in PPF each year?
You can deposit a minimum of ₹500 and a maximum of ₹1,50,000 per financial year, in a lump sum or in instalments. Deposits above ₹1.5 lakh earn no interest and aren't eligible for tax benefit.
Is PPF tax-free?
PPF has EEE (Exempt-Exempt-Exempt) status: contributions qualify for deduction under Section 80C, the interest earned is tax-free, and the maturity amount is tax-free — one of the reasons it's a popular long-term, low-risk option.
Is my data uploaded?
No — the projection runs entirely in your browser.
