What is PPF Calculator?
PPF Calculator projects the maturity amount of a Public Provident Fund account over its 15-year tenure, based on your annual deposit and the prevailing interest rate, with a full year-by-year balance breakdown.
PPF is one of India’s best long-term tax-saving instruments — EEE tax status means deposits reduce taxable income (Section 80C), interest is tax-free, and the entire maturity corpus is tax-free.
PPF Key Facts
15-Year Lock-in
PPF has a mandatory 15-year tenure. Partial withdrawals allowed from year 7; premature closure only under specific conditions.
Compound Growth
Interest compounds annually. Deposits made before April 5th of each month earn interest for that full month.
Tax Benefits
EEE status: ₹1.5L/year deductible under 80C, interest tax-free, maturity tax-free.
How to Use PPF Calculator
Enter deposit
Enter your planned annual deposit (₹500–₹1,50,000). Most people deposit the maximum ₹1.5L for maximum 80C benefit.
Set interest rate
The current rate is pre-filled. Adjust it to model conservative scenarios (lower rate) or historical returns.
View maturity
See the 15-year maturity amount, total deposits made, and total interest earned.
Read year table
The year-by-year table shows opening balance, deposit, interest earned, and closing balance for all 15 years.
PPF Year-by-Year Growth
The power of PPF is compound growth over 15 years. At 7.1% with ₹1.5L annual deposits:
| Year | Total Deposited | Maturity Value | Interest Earned |
|---|---|---|---|
| 5 | ₹7.5L | ~₹8.8L | ~₹1.3L |
| 10 | ₹15L | ~₹21L | ~₹6L |
| 15 | ₹22.5L | ~₹40.7L | ~₹18.2L |
The interest in the final 5 years exceeds the interest earned in the first 10 — demonstrating the power of compounding.
Tips & Common Mistakes
Deposit before April 5th each month to earn interest on that deposit for the full month. Depositing on April 6th means you miss one month’s interest — over 15 years, timing adds up.
Don’t confuse PPF with ELSS. PPF gives guaranteed, tax-free returns. ELSS (Equity Linked Savings Scheme) can give higher returns but with market risk. PPF is appropriate for risk-averse, long-term capital preservation.
