Find the final amount of a PPF account.
PPF compounds annually — each year's contribution is added to the balance and the whole amount earns interest for the year.
Each year: (Balance + contribution) × (1 + rate)
What is the current PPF interest rate?
7.1% per year. This rate has not changed since April 2020, and the government reviews it every three months.
Is PPF interest taxable?
No. PPF is called an EEE product, which means all three stages are tax-free: your deposits get a Section 80C deduction, the interest is tax-free, and the final amount is tax-free too.
