How this is worked out
PPF compounds annually: each year's contribution is added, then 7.1%/yr interest is credited on the running balance. Over 15 years that turns ₹22.5 L of your own money into ₹40.68 L — and because PPF is EEE (exempt-exempt-exempt), none of that ₹18.18 L in growth is taxed, going in, growing, or coming out.
