Understanding PPF Calculator

What is PPF (Public Provident Fund)?

PPF is a long-term savings scheme backed by the Government of India, offering guaranteed returns with complete tax exemption. It's one of the safest investment options in India with triple tax benefits (EEE - Exempt-Exempt-Exempt). PPF has a lock-in period of 15 years, making it ideal for retirement planning and long-term goals. The interest rate is set by the government quarterly and compounds annually.

How Does Our PPF Calculator Work?

Our calculator uses the compound interest formula with annual compounding:

A = P × [(1 + r)^n - 1] / r

Where: A = Maturity Amount, P = Annual Investment, r = Annual Interest Rate, n = Number of Years

PPF interest is compounded annually and credited to your account at the end of each financial year (March 31).

Depositing Less Than ₹500: Account becomes inactive, requires reactivation with penalty

Year-End Deposits: Lose interest for entire year. Always deposit early in financial year.
Not Nominating: Nomination simplifies claim process for family in case of death
Premature Closure: Lose tax benefits and interest for full 15-year compounding
Ignoring Extension: After 15 years, extend for 5 more years to maximize tax-free wealth
Taking Loan Unnecessarily: Loan interest (8.1%) eats into your returns. Avoid unless emergency.
