About this calculator
Public Provident Fund (PPF) Investment Guide
The Public Provident Fund (PPF) is one of the most popular long-term, government-backed savings schemes in India. Introduced by the National Savings Institute in 1968, it offers a compelling combination of safety, guaranteed returns, and massive tax benefits.
Our PPF Calculator helps you determine the maturity value of your investment after the mandatory 15-year lock-in period, showing exactly how your money compounds tax-free over time.
Why Invest in PPF? (The EEE Benefit)
The biggest draw of the PPF is its "Exempt-Exempt-Exempt" (EEE) tax status, available under the Old Tax Regime:
- Exempt Investment: The amount you invest in PPF (up to ₹1.5 Lakhs per year) is deductible from your taxable income under Section 80C.
- Exempt Interest: The interest accumulated every year is completely tax-free.
- Exempt Maturity: The entire corpus (principal + interest) you withdraw at maturity is absolutely tax-free.
Key Rules of a PPF Account
- Investment Limits: You must invest a minimum of ₹500 per financial year to keep the account active. The maximum amount you can invest is ₹1,50,000 per financial year.
- Lock-in Period: The PPF has a strict 15-year maturity period. However, partial withdrawals are permitted from the 7th financial year onwards under specific conditions.
- Interest Calculation: The government reviews and sets the PPF interest rate every quarter. A crucial detail: Interest is calculated on the minimum balance between the 5th and the last day of every month. Therefore, to maximize your interest, it is always best to deposit your money on or before the 5th of the month.
- Extension: After the 15-year maturity, you can extend your PPF account in blocks of 5 years indefinitely, either with or without making further contributions.
How to Use the PPF Calculator
- Yearly Investment: Enter the amount you plan to deposit into your PPF account every financial year (maximum ₹1.5 Lakhs).
- Time Period: The default is 15 years. You can change this if you plan to extend your PPF account in 5-year blocks (e.g., 20, 25, or 30 years).
- Interest Rate: The calculator uses the current prevailing government interest rate for accuracy.
Formula
Investment Returns Formula
The compound interest formula for investments:
A = P(1 + R/100)^N
Where:
- A = Final amount
- P = Principal (initial investment)
- R = Annual rate of return (%)
- N = Time period (years)
Simple vs Compound Returns
Simple Interest (rarely used): Interest = P × R × T ÷ 100
Compound Interest (most investments): Interest compounds periodically (quarterly, monthly, or annually), earning returns on previous returns.
SIP (Systematic Investment Plan) Formula
For monthly SIP investments:
FV = M × [((1 + r)^n - 1) / r] × (1 + r)
Where:
- FV = Future Value
- M = Monthly investment amount
- r = Monthly return rate
- n = Number of months

Investment Planning Framework
Step 1: Define Your Financial Goals
- Short-term (1-3 years): Emergency fund, vacation, gadgets
- Medium-term (3-10 years): Home down payment, car, education
- Long-term (10+ years): Retirement, wealth creation
Step 2: Assess Your Risk Tolerance
- Age and income stability: Younger with stable income = higher risk capacity
- Family responsibilities: More dependents = lower risk capacity
- Emergency fund: Must have 6 months expenses before investing
- Investment timeline: Longer timeline = can tolerate more volatility
Step 3: Determine Asset Allocation
- Rule of thumb: 100 - Age = % in stocks
- Age 30: 70% stocks, 30% bonds/conservative
- Age 40: 60% stocks, 40% bonds/conservative
- Age 50: 50% stocks, 50% bonds/conservative
Step 4: Choose Investment Vehicles
- Stocks: High growth, high risk (long-term)
- Bonds/FDs: Stable, low growth (capital preservation)
- Mutual funds: Diversified, professional management
- Real estate: Illiquid, tangible asset
- Gold: Inflation hedge, low growth
Step 5: Start Investing
- Start with SIP for rupee-cost averaging
- Invest amount you can afford to lose
- Don't time the market, stay invested
- Review quarterly, rebalance annually
Key Investment Principles
Diversification: Don't put all money in one investment. Spread across:
- Different asset classes (stocks, bonds, real estate)
- Different sectors (IT, pharma, finance, consumer)
- Different instruments (direct stocks, mutual funds, ETFs)
Compound Interest Power: Start early to benefit from compounding:
- ₹10,000/month from age 25: ₹2.75 crore by age 60 (12% returns)
- ₹10,000/month from age 35: ₹1.05 crore by age 60 (same returns)
- Starting 10 years earlier = 2.6X more wealth
Regular Review:
- Check portfolio performance quarterly
- Rebalance if allocation drifts >5%
- Adjust for life changes (marriage, children, job change)
- Keep expense ratio low (<1% for mutual funds)
Avoiding Investment Mistakes
- Chasing High Returns: Higher return = higher risk
- Panic Selling: Selling during crashes locks in losses
- Lack of Diversification: Overconcentration increases risk
- Ignoring Inflation: Returns must beat inflation to create real wealth
- Delaying Start: Time in market beats timing the market
Frequently Asked Questions
Can I open multiple PPF accounts?
No, an individual is allowed to open only one PPF account in their name across all banks and post offices in India. However, you can open a second account in the name of your minor child as a guardian.
What is the maximum amount I can invest in PPF?
The maximum limit is ₹1,50,000 per financial year. Even if you hold an account for yourself and act as a guardian for a minor's account, the combined total contribution across both accounts cannot exceed ₹1.5 Lakhs in a single year to claim tax benefits.
What happens if I forget to deposit ₹500 in a year?
If you fail to make the minimum ₹500 deposit in a financial year, your PPF account becomes inactive. To revive it, you must pay a penalty of ₹50 for every year defaulted, along with the minimum deposit of ₹500 for each missed year.
When is the best time to deposit money into a PPF account?
To maximize your interest, you should deposit the money on or before the 5th of the month (if making monthly deposits), or between April 1st and April 5th (if making a yearly lump-sum deposit). This ensures the money earns interest for that entire month.
Can an NRI open a PPF account?
Non-Resident Indians (NRIs) are not permitted to open a new PPF account. However, if an Indian resident opens a PPF account and subsequently becomes an NRI during the 15-year tenure, they are allowed to continue contributing to the account until maturity on a non-repatriable basis.
Can I take a loan against my PPF balance?
Yes, you can take a loan against your PPF account from the 3rd to the 6th financial year of opening the account. The loan amount is capped at 25% of the balance available at the end of the second year immediately preceding the year you apply for the loan.

Frequently Asked Questions
What is the lock-in period for a PPF account and can I withdraw early?
A PPF account has a mandatory lock-in period of 15 years. You cannot make full withdrawals before this period ends, but partial withdrawals are permitted from the 7th financial year onwards under certain conditions. After the 15-year term, you may extend the account in blocks of 5 years.
How is PPF interest calculated and when is it credited?
PPF interest is calculated on the lowest balance in your account between the 5th and last day of each calendar month, then credited at the end of the financial year (March 31). To maximise interest, it is advisable to deposit before the 5th of each month so the deposit counts in that month's calculation.
What is the minimum and maximum amount I can invest in PPF per year?
You must deposit a minimum of ₹500 per financial year to keep the account active. The maximum permissible deposit is ₹1,50,000 per financial year across all your PPF accounts. Deposits can be made in a lump sum or in up to 12 instalments.
What tax benefits does a PPF investment offer?
PPF follows the Exempt-Exempt-Exempt (EEE) structure: the amount you invest qualifies for deduction under Section 80C; the interest earned is fully tax-free; and the maturity proceeds are also exempt from income tax. This makes PPF one of the most tax-efficient savings instruments available in India.
How does this calculator estimate my PPF maturity amount?
The calculator uses the standard PPF compounding formula, applying the prevailing interest rate (announced by the government quarterly) to your annual deposits over the chosen tenure. It compounds interest annually and shows your total invested amount, interest earned, and projected maturity value.
