Ppf Account Interest Calculator

Public Provident Fund (PPF) accounts are a popular long-term savings instrument in India, offering attractive interest rates and tax benefits. This calculator helps you determine the interest earned on your PPF account over time.

How PPF Accounts Work

PPF accounts are government-backed savings schemes in India. Here's what you need to know:

Minimum investment: ₹500 per year
Maximum investment: ₹1,50,000 per year (₹1,500 per month)
Lock-in period: 15 years
Interest rate: Currently 7.1% per annum (as of 2023)
Tax benefits: Interest earned is tax-free under Section 80C of the Income Tax Act

The interest is calculated annually on the balance in the account, which includes both the principal and the accumulated interest. The account matures after 15 years, after which the entire amount can be withdrawn.

PPF Interest Calculation

The interest on a PPF account is calculated using the following formula:

Maturity Amount = P × [(1 + r)^n - 1] / r

Where:

P = Annual investment amount
r = Annual interest rate (in decimal)
n = Number of years

The interest is compounded annually, meaning each year's interest is added to the principal for the next year's calculation.

Note: The actual interest rate may change each year based on government notifications. This calculator uses the current rate of 7.1% per annum.

Example Calculation

Let's say you invest ₹10,000 per year in a PPF account with an annual interest rate of 7.1% for 15 years.

Year	Opening Balance	Annual Investment	Interest Earned	Closing Balance
1	₹0	₹10,000	₹0	₹10,000
2	₹10,000	₹10,000	₹710	₹20,710
3	₹20,710	₹10,000	₹1,493	₹32,203
...	...	...	...	...
15	₹1,20,20,000	₹10,000	₹8,414	₹1,30,21,414

After 15 years, your total maturity amount would be approximately ₹1,30,21,414, including the principal and interest earned.
