Calculate maturity value of Public Provident Fund (PPF) with current 7.1% interest rate.
The Public Provident Fund (PPF) is a long-term, tax-free savings instrument backed by the Government of India. It offers a fixed interest rate (currently 7.1% as of FY25-26, reviewed quarterly), a 15-year lock-in period (extendable in 5-year blocks), and a maximum annual contribution of ₹1.5 lakh per individual.
PPF qualifies for the "EEE" (Exempt-Exempt-Exempt) tax treatment in India — your contribution is deductible under Section 80C, the annual interest is tax-free, and the final maturity amount is tax-free. This makes PPF one of the highest post-tax-return debt instruments available to Indian investors, especially in higher tax brackets.
A = \sum_{k=1}^{n} P \times (1+r)^{n-k+1}
Inputs: ₹1,50,000 per year for 15 years at 7.1%
Partial withdrawals are allowed from the 7th financial year onwards, up to 50% of the balance at the end of the 4th year preceding the year of withdrawal. Premature closure is allowed after 5 years only in cases of serious illness, higher education, or change of residency. Otherwise the 15-year lock is strict.
You can — a parent or guardian can open a PPF account in a minor child's name. However the combined annual contribution across all your PPF accounts (yours + child's) is capped at ₹1.5 lakh, so you only get extra tax benefit if you fund both accounts from the child's own income (rare). Most parents prefer Sukanya Samriddhi (for daughters) or a regular equity SIP for higher long-term returns.
