How PPF interest is calculated
Interest is worked out every month on the lowest balance between the 5th and the end of the month, and credited once a year on 31 March. Deposit before the 5th, ideally by 5 April for the full year, to earn interest on it from that month.
Balance at year end ≈ (opening balance + deposit) × (1 + rate)repeated for 15 years when you deposit at the start of each yearWorked example
Example: ₹1.5 lakh at the start of every year for 15 years at 7.1%
Total deposited: ₹22.5 lakh.
Maturity value: about ₹40.68 lakh, of which ₹18.18 lakh is tax-free interest.
Extending for another 5 years with deposits would take it to roughly ₹66 lakh. The rate can change every quarter, so treat long projections as estimates.
