PPF (Public Provident Fund) is a government long-term savings scheme with a 15-year account term and a government-set interest rate reviewed quarterly. This page shows maturity examples at a constant rate and summarises the PPF Scheme, 2019 as notified. We have not checked later amendments, so confirm current conditions with your bank or post office. Tax treatment is not covered.
1. What is PPF (Public Provident Fund)?
The Public Provident Fund is a voluntary long-term savings scheme run under the PPF Scheme, 2019, made under the Government Savings Promotion Act, 1873.
The account has a mandatory lock-in of 15 financial years. After maturity, you can extend it indefinitely in 5-year blocks. Interest is compounded annually and credited to your account on 31st March every year. The calculation, however, is based on the minimum balance between the 5th and the last working day of each month — which makes deposit timing crucial.
2. PPF Interest Rate 2026 & How It Is Calculated
Press reports put the PPF rate for October–December 2026 (Q3 of FY 2026-27) at 7.1% per annum, compounded annually. The Government of India reviews this rate every quarter (April, July, October, January); see the Department of Economic Affairs small savings page for the current one.
Interest is calculated on the minimum balance between the 5th and the last day of each month. This means that if you deposit money after the 5th of the month, that deposit earns zero interest for that month. The Scheme credits interest at the end of each year.
| Financial Year | PPF Interest Rate |
|---|---|
| October–December 2026 (per press reports) | 7.1% p.a. |
3. PPF Returns Calculation — Real Examples with Numbers
Understanding PPF returns is easiest with concrete examples. The formula for PPF maturity is: M = P × [((1 + r)^n – 1) / r] × (1 + r), where M is the maturity amount, P is the annual deposit, r is the annual interest rate, and n is the number of years. Our free PPF calculator handles this automatically, but let's look at real scenarios. These figures assume a constant 7.1% rate, annual compounding and the full yearly deposit made at the start of each year; real results differ because the rate changes and interest is calculated on the monthly lowest balance.
| Annual Deposit | Total Invested (15 yrs) | Total Interest Earned | Maturity Amount |
|---|---|---|---|
| ₹500/month (₹6,000/yr) | ₹90,000 | ₹72,736 | ₹1,62,736 |
| ₹5,000/month (₹60,000/yr) | ₹9,00,000 | ₹7,27,284 | ₹16,27,284 |
| ₹10,000/month (₹1,20,000/yr) | ₹18,00,000 | ₹14,54,569 | ₹32,54,569 |
| ₹12,500/month (₹1,50,000/yr) | ₹22,50,000 | ₹18,18,209 | ₹40,68,209 |
If you extend your PPF account beyond 15 years, the power of compounding becomes even more visible. At ₹1,50,000 per year for 25 years, your total invested amount of ₹37.5 lakh grows to over ₹1.03 crore — if the rate stayed constant for all 25 years, which is not guaranteed.
4. Tax Treatment
This page does not state the income-tax treatment of PPF deposits, interest or maturity for FY 2026-27, because we could not confirm it under the Income-tax Act, 2025. Check incometaxindia.gov.in or ask a tax professional.
5. PPF Deposit Rules and Limits
Under the PPF Scheme, 2019, a deposit must be at least ₹500 and at most ₹1,50,000 in a year, in multiples of ₹50, as a lump sum or in instalments. If the minimum is not deposited in a year the account is treated as discontinued; it can be revived during its maturity period by paying ₹50 plus the ₹500 arrears for each year of default.
| Rule | Details |
|---|---|
| Minimum Deposit/Year | ₹500 |
| Maximum Deposit/Year | ₹1,50,000 |
| Manner of Deposit | Lump sum or instalments, in multiples of ₹50 |
| Account Maturity | 15 years from the end of the year of opening |
| Interest | Credited at the end of each year |
| Interest Calculation | On the lowest balance between the 5th and the last day of the month |
6. PPF Withdrawal, Loan & Premature Closure Rules
As notified in the PPF Scheme, 2019, one partial withdrawal a year is allowed after five years from the end of the year of opening, up to 50% of the balance at the end of the fourth year before the withdrawal year or of the preceding year, whichever is lower. It is not allowed from a discontinued account.
A loan can be taken after one year and before five years from the end of the year of the first deposit (roughly the 3rd to 6th financial year), up to 25% of the balance at the end of the second year before the year of application, one loan a year. The principal is to be repaid within 36 months. Interest is 1% a year on the loan if repaid within 36 months; if not, it is 6% a year instead of 1% (not on top of it) from the first day of the month after the loan was drawn.
| Feature | Condition (Scheme as notified, 2019) |
|---|---|
| Partial Withdrawal | After 5 years; 50% of the lower balance; once a year |
| Loan Against PPF | After 1 and before 5 years from the end of the opening year; 25% of the balance two years back |
| Premature Closure | After 5 years, only on the grounds in paragraph 13; interest 1% lower |
| Extension without deposits | After 15 years; one withdrawal a year |
| Extension with deposits | After 15 years; apply in Form 4 within one year of maturity; 5-year blocks; withdrawals capped at 60% of the block-start balance |
7. Opening a PPF Account
An individual opens an account by applying in Form 1 to an accounts office with a minimum first deposit of ₹500. An individual may also open one account for each minor or person of unsound mind they are guardian of; joint accounts are not allowed. Which banks and post offices offer it, whether online opening is available, and the KYC documents needed depend on the institution, so ask them directly.
