PPF Calculator
Calculate PPF maturity amount, total interest earned, and year-wise growth for any annual deposit at 7.1% — India's safest long-term investment.
What is the PPF Calculator?
The PPF Calculator (Public Provident Fund Calculator) helps you estimate the maturity value of your PPF account based on your annual deposit, interest rate, and tenure. PPF is one of India's most popular long-term savings instruments — it offers tax-free returns, government-backed safety, and Section 80C deductions up to ₹1.5 lakh per year.
PPF accounts have a minimum tenure of 15 years, extendable in blocks of 5 years. The current interest rate is 7.1% per annum (compounded annually, as set by the government quarterly). The maximum deposit is ₹1,50,000 per year and the minimum is ₹500 per year.
Why PPF Is Popular in India
PPF is EEE — Exempt-Exempt-Exempt. Contributions qualify for 80C deductions (exempt at investment), interest earned is tax-free (exempt at accumulation), and maturity proceeds are tax-free (exempt at withdrawal). This triple tax exemption makes PPF extremely attractive for long-term wealth building, especially for individuals in higher tax brackets.
PPF vs FD vs SIP
PPF offers guaranteed returns (unlike SIP which is market-linked) and higher returns than most FDs (typically 1-1.5% higher), with full tax exemption. For salaried professionals who want a safe, tax-efficient component in their portfolio, PPF is hard to beat.
How Does the PPF Calculator Work?
1. Enter Annual Deposit: Type how much you invest in your PPF account each year (max ₹1,50,000).
2. Enter Interest Rate: Pre-filled at 7.1% (current government rate). You can adjust if the rate changes.
3. Enter Tenure: How many years you plan to stay invested (minimum 15 years).
4. View Results: See your maturity amount, total amount deposited, and total interest earned.
Formula & Calculation Method
PPF Maturity Formula (beginning-of-year deposits):
M = P × (1+r) × [(1+r)^n − 1] / r
Where:
- P = Annual deposit amount
- r = Annual interest rate / 100
- n = Number of years
This assumes deposits are made at the beginning of each financial year (April), which maximizes interest earned. If deposits are made later in the year, actual maturity may be slightly lower.
Example Calculation
Example: ₹1,50,000 annual deposit, 7.1% interest, 15 years
Maturity = 1,50,000 × 1.071 × (1.071^15 − 1) / 0.071 ≈ ₹40,68,209
Total deposited = 1,50,000 × 15 = ₹22,50,000
Total interest = ₹40,68,209 − ₹22,50,000 = ₹18,18,209 (tax-free!)
