Method

Deposit by 5 April: Balance = (Balance + D) × (1 + i) each year, so FV = D × [(1 + i)ⁿ − 1] ÷ i × (1 + i). Deposit at year end: FV = D × [(1 + i)ⁿ − 1] ÷ i

D
yearly deposit
i
interest rate ÷ 100
n
number of years

Worked example

  1. 1.071¹⁵ = 2.79796, so [(1.071¹⁵ − 1) ÷ 0.071] × 1.071 = 27.1214.
  2. Maturity = 1,50,000 × 27.1214 = ₹40,68,209.
  3. Deposits = 15 × 1,50,000 = ₹22,50,000, so interest = ₹18,18,209.

Depositing the maximum ₹1.5 lakh every year by 5 April at 7.1% gives about ₹40.68 lakh after 15 years.

What the result means

Depositing by 5 April each year earns interest for the whole year; a deposit at the end of the year earns nothing that year. PPF interest is set by the government each quarter, so the real figure will differ if the rate changes.

Assumptions and limits

  • Deposit limits of ₹500 to ₹1,50,000 per financial year, maturity after 15 complete financial years and 5-year extensions with deposits, as stated by the National Savings Institute (checked 29 October 2026).
  • One deposit a year, and the rate you enter applies for the whole period.
  • Interest is credited at the end of each financial year and compounds yearly.
  • Interest is actually worked out monthly on the lowest balance between the 5th and the end of the month; deposits after the 5th earn less than shown.
  • Loans and partial withdrawals are not modelled.

Questions

What is the PPF interest rate?

The government sets it every quarter. Enter the rate in force; the 7.1% default is only an example.

Can I continue PPF after 15 years?

Yes. The account can be extended in blocks of 5 years with further deposits, or kept without deposits, earning the prevailing rate.
