PPF Calculator
Calculate the maturity value and interest of a Public Provident Fund account for any yearly deposit, rate and tenure.
How it works
Each year: balance = (balance + yearly deposit) × (1 + rate) — deposits are made at the start of the year and interest compounds annually
The Public Provident Fund is a government-backed savings scheme where you deposit up to a yearly cap and the balance compounds once a year at a rate the government sets. Because the deposit is treated as made at the start of the year, it earns a full year of interest, and both the interest and the maturity amount are tax-free. This calculator adds each year deposit, compounds the running balance, and shows how the interest builds up over the tenure.
Worked example
Depositing the ₹1.5 lakh annual maximum for 15 years at 7.1% grows to about ₹40.68 lakh. Of that, ₹22.5 lakh is your own deposits and roughly ₹18.18 lakh is tax-free interest earned along the way.
Frequently asked questions
What are the PPF limits and lock-in?
A PPF account has a 15-year lock-in, a minimum deposit of ₹500 and a maximum of ₹1.5 lakh in a financial year. After 15 years you can extend in blocks of five years, with or without fresh deposits.
How often does the PPF rate change?
The government reviews small-savings rates every quarter, so the PPF rate can change through the life of your account. The 7.1% default here is the rate at the time of writing — confirm the current figure before relying on the result.
Is PPF interest taxable?
No. PPF falls under the exempt-exempt-exempt regime, so your deposits qualify for a deduction, the annual interest is tax-free and the maturity amount is tax-free too. That makes the effective return higher than a taxable deposit at the same rate.
