Note: Interest rates are reviewed by the Ministry of Finance in consultation with RBI. Changes typically occur every quarter.

How to Calculate PPF Returns

The PPF calculator uses the compound interest formula for periodic deposits:

Maturity Value = P × [((1+r)^n - 1) / r] × (1+r)

Where:
P = Annual investment
r = Rate of interest ( Quarterly compounded: divide annual rate by 4)
n = Number of quarters (Years × 4)

Example Calculation

Scenario: Invest ₹1.5 lakh annually (₹12,500/month) at 7.1% for 15 years

Annual Investment (P) = ₹1,50,000
Rate (r) = 7.1% / 4 = 1.775% per quarter
Period (n) = 15 × 4 = 60 quarters

Maturity Value ≈ ₹44.2 lakhs
Total Invested = ₹22.5 lakhs
Interest Earned ≈ ₹21.7 lakhs

PPF Top-up and Partial Withdrawal

Top-up Contributions

You can increase contributions above ₹1.5 lakh in the financial year. However, excess amount gains interest at 1% below the prevailing rate. It's generally better to stay within ₹1.5 lakh limit.

Partial Withdrawal (After Year 12)

After 12 years, you can withdraw partially without closing the account. Rules:
