Why the date of deposit matters
PPF interest is worked out on the lowest balance between the 5th and the last day of each month. A deposit made after the 5th earns nothing for that month. Depositing the full year’s amount before 5 April earns interest on all of it for the entire year. With ₹1.5 lakh a year for 15 years at 7.1%, the maturity value looks like this.
| Deposit pattern | Total deposited | Maturity value |
|---|---|---|
| Lump sum before 5 April | ₹22,50,000 | ₹40,68,209 |
| ₹12,500 a month, before the 5th | ₹22,50,000 | ₹39,44,599 |
| ₹12,500 a month, after the 5th | ₹22,50,000 | ₹39,22,125 |
The lump-sum approach earns about ₹1.2 lakh more over 15 years for the same money.
Withdrawals, loans and extension
- Partial withdrawal is generally allowed from the 7th financial year, up to 50% of the balance at the end of the 4th preceding year or the immediately preceding year, whichever is lower.
- Loan against PPF is generally available between the 3rd and 6th financial year.
- Extension: after 15 years you can extend in 5-year blocks, with or without fresh contributions. To keep contributing, you need to submit the extension request in time.
- Premature closure is allowed only in specific cases after 5 years, such as serious illness or higher education.
Rules are administered by banks and post offices, so confirm the current conditions where your account is held.
Is PPF a good investment?
PPF is backed by the government, has tax-free returns and no market risk. The trade-off is the long lock-in and a rate that can change every quarter. It suits conservative, long-term goals such as retirement or a child’s education. Compare it with equity options using the step-up SIP calculator before deciding how much to allocate to each.
Limitations
The calculator assumes the account starts at the beginning of a financial year and that the rate you enter stays the same throughout. Real PPF rates are reviewed every quarter, so actual maturity can differ.
