  • PPF interest and maturity are tax-free. A taxable FD would need to pay about 10.3% to match 7.1% for someone in the 30% slab.
  • In the old tax regime, deposits count towards 80C: up to ₹46,800 of tax saved each year at the 30% slab.
  • In today's money, at 6% inflation, the maturity is worth about ₹16,97,522.
  • Deposit by 5 April each year: PPF interest is worked out on the lowest balance between the 5th and the end of each month.

How is PPF interest calculated?

Interest is worked out every month on the lowest balance between the 5th and the last day of the month, and credited once a year on 31 March. Depositing before the 5th, ideally by 5 April for a yearly deposit, earns the most.

Can I withdraw from PPF before maturity?
