About PPF
The Public Provident Fund is a government-backed savings scheme with a 15-year lock-in, available at post offices and banks. Interest is compounded yearly, and deposits, interest and maturity are all tax-free (EEE) under the old regime.
How the calculation works
This calculator assumes you deposit at the start of each financial year (before 5 April), so the full deposit earns interest for that year: balance = (previous balance + deposit) × (1 + rate).
PPF rules at a glance
- Minimum ₹500 and maximum ₹1.5 lakh per financial year.
- Lock-in 15 years; extend in blocks of 5 years.
- Partial withdrawal allowed from the 7th year; loan facility from year 3.
- Deposits qualify for Section 80C deduction under the old regime.
Frequently asked questions
When should I deposit to earn maximum interest?
Deposit before the 5th of April (or before the 5th of each month for monthly deposits) so the amount earns interest for the full period.
Can I extend PPF after 15 years?
Yes, in blocks of 5 years, with or without fresh deposits.
Is PPF interest tax-free?
Yes. PPF has EEE status – deposit, interest and maturity are tax-exempt.
