How the PPF calculation works

PPF compounds annually on deposits made during the year. This tool assumes the full yearly deposit is made at the start of the year, so Maturity = P × (((1 + r)ᵗ − 1) / r) × (1 + r), with P as your annual deposit, r the current PPF rate (7.1% p.a., revised quarterly by the government), and t the tenure in years.

The rate has ranged between 7.1% and 8% over the last decade; the tool holds it at the current 7.1% for the full tenure.

Worked example

Depositing the maximum ₹1,50,000 every year for the full 15-year term:

Yearly deposit₹1,50,000
Rate · tenure7.1% · 15 years
Total deposited₹22,50,000
Interest earned₹18,18,209
Maturity value₹40,68,209

Extend the same account in 5-year blocks after maturity and the corpus keeps snowballing — ₹66.58L by year 20 on unchanged deposits.

Frequently asked questions

What is the current PPF interest rate?
The government reviews PPF rates quarterly; it has held at 7.1% p.a. since Q1 2020. Interest is tax-free, which makes the post-tax comparison with FDs even stronger for higher slabs.
Can I extend my PPF after 15 years?
Yes, in unlimited 5-year blocks — either with fresh deposits or as a "without contribution" extension where the balance keeps compounding. Many households run the no-deposit extension purely for the tax-free compounding.
Is PPF maturity amount taxable?
No. PPF enjoys EEE status — deposits get 80C deduction, interest accrues tax-free, and maturity is exempt. It is one of the last fully tax-free instruments available.
How much can I deposit in PPF per year?
Between ₹500 and ₹1,50,000 per financial year. Deposits beyond ₹1.5L earn no interest, so surplus money belongs in other instruments.
