What is PPF?
The Public Provident Fund (PPF) is a government-backed small savings scheme launched in 1968. It is one of the most secure ways to grow your money while also enjoying EEE tax benefits (Exempt-Exempt-Exempt).
- Exempt at investment: You get tax deduction under Section 80C up to ₹1.5 lakh.
- Exempt during interest: The interest you earn is completely tax-free.
- Exempt on maturity: The final maturity amount is also tax-free.
That means zero tax leakage throughout the investment journey – something very few financial instruments offer.
Why PPF is a Long-Term Wealth Builder
PPF comes with a 15-year lock-in period, which may sound restrictive but is actually a blessing in disguise. Because of this long tenure, the power of compounding works beautifully, multiplying your wealth over time.
Let’s say you invest ₹1,50,000 annually in PPF. With an interest rate of 7.1% (as of now), over 15 years, you will not just get back your invested money but also a handsome compounding interest amount.
That’s where the PPF calculator helps you visualize the impact of compounding clearly.
The PPF Formula
The formula for calculating interest in a PPF account is slightly different from normal simple compounding.
Each year’s balance is calculated as: A=P×(1+r)n−1rA = P \times \frac{(1 + r)^n - 1}{r}A=P×r(1+r)n−1
Where:
- AAA = Maturity amount
- PPP = Annual investment
- rrr = Rate of interest (7.1% = 0.071)
- nnn = Number of years
The interest is compounded annually. That’s why if you invest regularly, each year’s investment earns compound interest till maturity.
Example – Using the PPF Calculator
Suppose you invest ₹1,00,000 every year for 15 years.
- Principal invested = ₹15,00,000
- Interest rate = 7.1% per annum (compounded yearly)
- Tenure = 15 years
Result:
- Maturity Value = ₹21,21,214
- Interest Earned = ₹6,21,214
This shows that without taking any market risk, you earned over ₹6 lakh extra simply because of compounding.
The best part? If you keep extending PPF in 5-year blocks after 15 years, your wealth keeps growing exponentially.
Benefits of Using a PPF Calculator
- Accurate Estimates – No manual mistakes, just clear results.
- Future Planning – Helps you decide how much to invest annually.
- Compounding Visualization – Shows how small amounts grow big over years.
- Comparison – Compare with other investments like FD, mutual funds, or NPS.
- Tax-Free Growth – Reminds you of the EEE benefit, which boosts your net return.
Why You Shouldn’t Ignore Compounding
Albert Einstein called compounding the 8th wonder of the world – and PPF is the perfect example of this principle.
If you invest early and consistently, your interest on interest keeps piling up. For instance:
- If you start PPF at age 25 and invest ₹1,50,000 per year, at age 40 you’ll already have over ₹30 lakh+.
- If you start at age 35, for the same investment, by age 50 you’ll only have around ₹18-20 lakh.
The lesson? Start early, invest consistently, and let compounding do the heavy lifting.
How to Use the PPF Calculator
Using the calculator is simple:
- Enter the annual investment amount.
- Enter the rate of interest (currently 7.1%).
- Enter the tenure (15 years minimum, extendable in 5-year blocks).
- Hit calculate, and the tool instantly shows:
- Maturity Value
- Total Principal Invested

This takes away all the guesswork and gives you a realistic picture of your financial future.
PPF vs Other Safe Investments
| Investment Type | Lock-in | Interest Rate | Tax Benefits | Risk | Liquidity |
|---|---|---|---|---|---|
| PPF | 15 years | ~7.1% | EEE (fully exempt) | Very Safe | Partial withdrawal after 7 years |
| Fixed Deposit | 5 years | 6–7% | Tax-saving FD under 80C | Safe | Locked for tenure |
| NPS | Till retirement | Market linked | EEE (partial tax-free) | Moderate | Locked till 60 |
| Sukanya Samriddhi Yojana | 21 years | ~8% | EEE | Very Safe | Limited |
Clearly, PPF holds a sweet spot for safety + compounding + tax benefits.
