How PPF Interest is Calculated — Year-by-Year
PPF interest is calculated on the minimum balance between the 5th and last day of each month and credited annually on March 31st. This means you should deposit before the 5th of each month to earn interest for that month. The formula compounds your deposits annually over 15 years.
F = P × [((1 + i)ⁿ - 1) / i]Where:
- • F = Maturity Amount at end of tenure
- • P = Annual deposit amount (max ₹1,50,000)
- • i = Annual interest rate ÷ 100 (currently 7.1% → 0.071)
- • n = Number of years (minimum 15)
- • Example: ₹1.5L/year for 15 yrs @ 7.1% → Maturity = ₹40,68,209
- Year-by-Year Growth (₹1.5L/year @ 7.1%): Year 1: ₹1,60,650 | Year 5: ₹9,13,847 | Year 10: ₹21,95,337 | Year 15: ₹40,68,209. Your money nearly doubles from Year 10 to Year 15 due to compounding!
- Deposit Tip: Deposit before April 5th each year to earn interest for the full year. A yearly deposit of ₹1.5L vs monthly deposits of ₹12,500 gives slightly higher returns when invested as lump sum early in April.
- PPF Interest Rate History: The rate is set by the government quarterly. It was 8.7% (2016), 7.9% (2020), 7.1% (2020–present). Historically between 6.5–12% — still attractive for risk-free, tax-free returns.
- EEE Status Explained: E1 — Investment up to ₹1.5L deductible under Section 80C. E2 — Annual interest earned is NOT taxed. E3 — Maturity amount (₹40.68L in above example) is completely tax-free. No other instrument offers all three.
