What is a PPF Calculator?

A PPF Calculator is an online tool designed to help you calculate the returns on your Public Provident Fund (PPF) investments. By entering details like your investment amount, frequency, interest rate, and duration, the calculator provides accurate estimates of your maturity amount, total contributions, and interest earned over the investment period.

Whether you're planning for retirement, saving for your child's education, or building a financial safety net, a PPF calculator simplifies the process by giving you clear projections of your investment growth.

How Does a PPF Calculator Work?

A PPF calculator uses the compound interest formula to calculate your returns. The formula is:

Closing Balance = Opening Balance + Deposits + Interest Earned

Where:

Opening Balance: The balance at the start of the year.
Deposits: Total contributions made during the year.
Interest Earned: Calculated as (Opening Balance + Deposits) × Interest Rate.

The interest is compounded annually, and the closing balance for each year becomes the opening balance for the next year.

Practical Example of PPF Calculation

Let’s consider a practical example to understand how the PPF calculator works:

Scenario: You invest ₹5,000 monthly at an interest rate of 7.1% for 15 years.

Annual Deposit: ₹5,000 × 12 = ₹60,000
Total Deposits Over 15 Years: ₹60,000 × 15 = ₹9,00,000
Total Interest Earned: ₹8,50,000 (approx.)
Maturity Amount: ₹17,50,000 (approx.)

This example shows how your regular contributions can grow significantly over time due to compound interest.
