Most people think of the Public Provident Fund (PPF) as a simple retirement account.

Invest for 15 years. Let the money compound. Withdraw everything at maturity.

But the rulebook allows something far more interesting.

If structured properly, a PPF account can continue compounding while also paying you a regular tax-free income for decades. If you want to see how this fits into your overall portfolio, explore our personalised financial planning approach at Novelty Wealth.

This article explains a simple model that turns ₹15 lakh invested over 10 years into about ₹45.8 lakh of tax-free withdrawals over time.

The key lies in understanding PPF withdrawal rules and the post-maturity options.

What Is the Public Provident Fund

The Public Provident Fund is a long-term savings scheme backed by the Government of India.

It was introduced to give individuals a safe way to build wealth with guaranteed returns and full tax benefits.

Unlike market-linked investments:

• There is no NAV
• There is no fund manager
• There is no credit risk

The government sets the interest rate and guarantees both the principal and the interest.

Currently the interest rate is 7.1 percent per year (FY 2025–26). The rate is reviewed every quarter by the government.

PPF also falls under the EEE tax regime:

PPF also falls under the EEE (Exempt-Exempt-Exempt) tax regime. This means every rupee earned in PPF is tax-free. To understand how this compares to other assets, read our guide on how different capital gains are taxed in India.

PPF also has an additional legal protection. The balance cannot be attached by creditors under most circumstances. That makes it one of the safest financial assets available to Indian households.

The Core Rules You Need to Know

Understanding the rules is essential because the model works only if the rules are followed correctly.

Who Can Open a PPF Account

Only individuals can open a PPF account.

• One account per person
• Joint accounts are not allowed
• Guardians can open accounts for minors

However, the total contribution across the guardian and minor accounts cannot exceed ₹1.5 lakh per year.

Contribution Limits

Deposits should ideally be made before April 5 every year.

PPF interest is calculated on the lowest balance between the 5th and the last day of each month. If you deposit after April 5, you lose the interest for that month.

Interest Calculation

Current rate: 7.1 percent per year

Key points:

• Calculated monthly
• Credited once per year on March 31

This means the money compounds annually inside the account.

Loans Against PPF

A loan facility exists during the early years.

Loan window From Year 2 to Year 5

Loan limit Up to 25 percent of the balance from two years earlier

Loan interest 1 percent above the PPF interest rate

If not repaid within 36 months, the interest rate increases significantly.

After Year 5 the loan facility disappears and partial withdrawals become available instead.

The Withdrawal Rule That Makes This Strategy Possible

PPF allows partial withdrawals from Year 7 onward.

Each year you can withdraw up to the lower of two numbers:

1. 50 percent of the balance four years earlier
2. 50 percent of the previous year's balance

In practice the four-year-prior balance is usually lower, which becomes the effective limit.

This rule allows gradual withdrawals while the remaining balance continues earning interest.

What Happens After 15 Years

PPF matures after 15 years.

At maturity you get two choices.

Option 1: Continue Without Deposits

You simply keep the account active.

• No further deposits
• Interest continues
• You can withdraw any amount once per year

There is no percentage cap on withdrawals.

This option is the foundation of the model explained below.

Option 2: Extend With Deposits

You can also continue contributing.

To do this you must file Form 4 within one year of maturity.

Rules in this option:

• Deposits up to ₹1.5 lakh per year
• Maximum withdrawal of 60 percent of the balance every 5 years

Because of this restriction, the income model works better under Option 1.

The Model: Turning PPF Into a Tax-Free Income Stream

This structure is particularly effective for those following a comprehensive retirement planning process.

Investment Phase

A person starts PPF at age 50.

They invest the maximum allowed amount every year.

₹1,50,000 per year For 10 years

That works out to ₹12,500 per month.

Total invested over 10 years ₹15,00,000

During this period the money compounds at 7.1 percent annually.

Phase 1

Age 50 to 59

10 Years of Compounding

During the first phase:

• ₹1.5 lakh invested every year
• No withdrawals
• Full compounding

Total invested: ₹15 lakh Corpus at age 59: ₹22.3 lakh

This stage builds the capital base that will later generate income.

Phase 2

Age 60 to 64

Controlled Withdrawals Before Maturity

PPF allows withdrawals from Year 7 onward.

During this phase the strategy does two things:

1. Continue the minimum deposit of ₹500 per year
2. Withdraw ₹2,00,000 per year

The withdrawal remains within the official PPF limits.

Despite these withdrawals, the balance continues earning interest.

By the time the account reaches maturity at age 65, the balance is still roughly ₹19 lakh.

Phase 3

Age 65 to 82

Post-Maturity Income

Once the account matures, deposits stop completely.

The account is continued without new deposits.

This means:

• The balance keeps earning interest
• Any amount can be withdrawn once per year

The model withdraws:

₹2,00,000 every year

That equals roughly:

₹16,667 per month

This continues until the account balance is fully depleted at age 82.

The Final Numbers

In simple terms:

₹12,500 per month invested for 10 years can generate ₹16,667 per month for more than two decades.

All of it tax-free.

Important Rules to Follow

This model only works if a few details are handled correctly.

Deposit Before April 5

Depositing after April 5 reduces the interest calculation for that month.

Over many years this can reduce the total corpus meaningfully.

Respect the 15-Year Lock-In

PPF has a strict lock-in period.

Premature closure is allowed only for:

• Serious medical emergencies
• Higher education
• Change in residency status

Closing early reduces the interest rate by 1 percent from the beginning.

Stop Deposits After Maturity

To allow unlimited withdrawals, the account must continue without deposits after maturity.

If deposits continue, the account shifts into the extension-with-deposit rule which restricts withdrawals.

The Interest Rate Can Change

The current PPF rate is 7.1 percent.

Historically PPF rates have ranged between 7 percent and 12 percent depending on government policy.

Future returns may therefore differ from the model.

Who Should Use This Strategy

PPF is not for everyone. At 7.1%, you are not beating broad market equity returns. The Nifty 50 has delivered approximately 12% to 14% CAGR over long periods. Its not for wealth maximization; for that, SIP investments in equity are far superior.

PPF is right for you if:

• You are in the 20 to 30% tax bracket and want a guaranteed, tax-free return (consider combining this with tax loss harvesting for your equity side).
• You want a completely safe, government-backed component in your retirement corpus
• You want predictable monthly income in retirement without any market risk
• You want an asset that is legally protected from creditors and court orders
• You follow the 25x LCM strategy and need a reliable "Debt" bucket.

PPF is not right for you if:

• You need liquidity before 5 to 7 years
• You are building purely for wealth maximisation with high equity risk tolerance
• You are in a low tax bracket where the EEE advantage is minimal
• You want to deploy more than ₹1.5L/year into fixed-income instruments

The Bigger Picture

PPF is not a standalone retirement plan. It is the capital-preservation, guaranteed-income anchor of a well-constructed financial plan. Combined with equity mutual funds for wealth creation and adequate insurance for protection, PPF provides the one thing a retirement plan cannot do without: certainty.

Most people will earn more from equity. But no market instrument can guarantee that you will receive ₹16,667 every month for 23 years without a single year of negative return. PPF can.
