What does this PPF maturity corpus mean for you?
By investing ₹1,50,000 every year for 15 years, you will invest a total capital of ₹22,50,000. At the current sovereign rate of 7.1% p.a., your account earns ₹18,18,209 in cumulative compounding interest, yielding a guaranteed final tax-free corpus of ₹40,68,209.
- PPF enjoys true EEE (Exempt-Exempt-Exempt) tax status: deposit is tax-deductible u/s 80C, interest earned is 100% tax-free, and maturity amount is completely exempt from income tax.
- More than 45% of your final ₹40,68,209 maturity value is pure compound interest paid by the Government of India.
- Interest is calculated on the lowest balance between the 5th and the end of each month, so depositing before the 5th of April (or 5th of every month) maximizes your interest income.
How This Calculator Works
PPF calculates interest annually on the opening balance plus yearly deposits. The interest rate is notified quarterly by the Ministry of Finance and compounded at the end of each financial year (March 31).
F = P × [({(1 + i)^n} - 1) / i] × (1 + i)Variables in Formula:
Worked Step-by-Step Example
Suppose you deposit the maximum limit of ₹1,50,000 every year before the 5th of April at 7.1% p.a. for the standard 15-year PPF lock-in period.
Key takeaway: Your ₹22.5 Lakhs of personal savings compounds into ₹40.68 Lakhs of sovereign-guaranteed, completely tax-free wealth, while saving up to ₹46,800/year in income tax.
Common Mistakes to Avoid
⚠ Depositing after the 5th of the month
PPF interest is computed on the minimum balance between the 5th and the last day of each month. If you deposit on the 6th, you lose interest for that entire calendar month.
⚠ Depositing more than ₹1.5 Lakhs in a FY
Any deposit exceeding ₹1,50,000 across all PPF accounts (including minor accounts) earns 0% interest and is not eligible for tax deductions.
⚠ Closing account instead of extending with contribution
After 15 years, PPF can be extended in 5-year blocks indefinitely. Extending with contribution lets you continue compounding large balances with 100% tax freedom.
