Calculate the maturity value of your Public Provident Fund (PPF) at the current 7.1% rate — and see what that tax-free corpus is really worth after inflation.
PPF compounds annually; each year's deposit earns interest for the remaining tenure:
Where: A = annual deposit, r = 7.1% rate, n = years. Assumes deposits at the start of each financial year.
Depositing the maximum ₹1,50,000 every year for the full 15-year term at 7.1% grows to about ₹40.68 lakh — ₹22.5 lakh invested and roughly ₹18.2 lakh of tax-free interest. After 6% inflation, that corpus is worth about ₹17 lakh in today's purchasing power.
