Each deposit is assumed at the start of the year; interest is added at the end of the year.

How it works

With the same deposit D at the start of every year and interest r added once a year, the maturity amount is:

M = D × ((1 + r)n − 1) ÷ r × (1 + r)

  • D = yearly deposit
  • r = interest rate as a decimal (7% = 0.07), as you enter it
  • n = number of years

The first deposit earns interest for n years and the last for one year. At 0% the maturity amount is simply D × n. The scheme itself calculates interest under its own rules, so a real account can differ slightly.

Worked example

By hand: ₹1,000 a year for 2 years at 10%.

  1. Year 1: ₹1,000 grows to ₹1,000 × 1.1 = ₹1,100
  2. Year 2: (₹1,100 + ₹1,000) × 1.1 = ₹2,310
  3. Formula: ₹1,000 × (1.12 − 1) ÷ 0.1 × 1.1 = ₹2,310.00

Longer example: ₹1,00,000 a year for 15 years at 7% (an example rate).

  1. (1 + 0.07)15 = 2.759032
  2. M = ₹1,00,000 × (2.759032 − 1) ÷ 0.07 × 1.07 = ₹26,88,805.36
  3. Deposited ₹15,00,000; interest earned ₹11,88,805

Frequently asked questions

What is PPF?

The Public Provident Fund is a long-term savings scheme run by the Government of India. You deposit money every year, it earns interest set by the government, and you get the balance back when the account matures. The National Savings Institute page linked below lists the scheme's main features.

How does this calculator work out the maturity amount?

It assumes you deposit the same amount at the start of every year and that interest at the rate you enter is added to the balance once a year. Each year's interest is then earned on the deposits and on the interest already added.

Which interest rate should I enter?

Enter the current PPF rate from the official source, or a rate you want to test. The PPF rate is set by the government and can change, so this calculator does not fill one in for you. The default value is only a starting point, not the current rate.

How many years should I enter?

Enter the number of years you plan to deposit. Check the official scheme page for the account's maturity period and the rules for extending it. If you extend the account, you can enter the longer period here to see the effect.

Why might the real maturity amount differ?

The scheme calculates interest under its own rules and on the actual dates you deposit, and the rate can change during the account's life. This calculator uses one rate for every year and start-of-year deposits, so treat the result as an estimate.

Are there limits on how much I can deposit?

Yes, the scheme has minimum and maximum deposits per financial year. They are set by the rules and can change, so this page does not list them. Check the National Savings Institute page linked below before you plan your deposits.

Is PPF interest taxed?

The scheme has specific tax treatment under the Income Tax Act, described on the official page linked below. Tax rules can change, so check the current rules on the Income Tax Department website or with a tax professional.
