How the PPF calculator works
PPF interest is compounded once a year. The calculator assumes you deposit the full yearly amount at the start of each financial year (before 5 April), which earns interest for the whole year. Depositing later in the year earns less, because interest is worked out on the lowest balance between the 5th and the last day of each month.
Key PPF rules
- Deposit between ₹500 and ₹1,50,000 every financial year.
- The account matures after 15 full financial years and can be extended in blocks of 5 years.
- Deposits qualify for deduction under the old tax regime, and the interest and maturity amount are tax-free.
- Partial withdrawals and loans are allowed after the first few years, within limits.
