How to use the PPF Calculator

Enter your yearly deposit (minimum ₹500, maximum ₹1,50,000).
Enter the current PPF interest rate (set by the government every quarter).
Enter the investment period — 15 years minimum, extendable in blocks of 5.
Click Calculate to see total investment, interest earned and maturity value.

Formula used

F = Σ D × (1 + i)^k, for k = 1 to n

Interest is compounded annually. Deposits made before the 5th of a month earn interest for that month, so depositing early in April earns the most.

Worked example

₹1,50,000 every year for 15 years at 7.1%

Total invested = ₹22,50,000

Maturity value ≈ ₹40,68,209

Interest earned ≈ ₹18,18,209 — fully tax-free

Why PPF is popular

PPF has EEE tax status: the deposit qualifies for Section 80C deduction (old regime), the interest is tax-free, and the maturity amount is tax-free. It is backed by the Government of India. The trade-off is liquidity — partial withdrawals are allowed only from the 7th financial year, and loans from the 3rd to 6th year.

Tips for accurate results

Deposit before 5 April each year to earn interest for the full year.
You can extend the account after 15 years with or without fresh deposits.
The rate can change every quarter; this calculator assumes a constant rate.
