What is a PPF Calculator?

A PPF Calculator online is a free tool that estimates how much you will grow your PPF savings into maturity. With a 15 year lock-in period, (which you can extend in blocks of 5 years), you get a snapshot of your total contributions, yearly interests earned, and payout they would receive at the end of the maturity period.

Simply enter your:

• Annual contribution
• Tenure, (15 years, or extended term)
• Current PPF interest rate (available quarterly from Government of India)
• Start year of investment.

Once you enter this, the calculator will immediately show you what you can expect to get as a payout amount and a PPF growth chart will be generated to represent your annual savings growth.

How Does the PPF Calculator Work?

The calculator works using four key inputs:

• Contribution Amount – The amount that you contribute every year (up to ₹1.5 lakh per year).
• Tenure -15 years by default, but can be extended in blocks of 5.
• Interest rate - The current PPF rate is set by the Ministry of Finance, which is published once every calendar quarter.
• Compounding - Interest is compounded once a year.

From these parameters, the calculator calculates:

• Total money invested during the tenure.
• Total interest earned.
• Final maturity amount.
• Year to year growth of the balance, and will provide an alternate graphic for a clearer growth trend.

Formula Used for Calculating PPF

The formula to calculate PPF maturity is:

Where:

• P = Annual deposit
• i = Interest rate
• n = Number of years
• F = Maturity value

Example: If you deposit ₹1,00,000 annually for 15 years at 7.1% interest, the formula gives you the approximate maturity value.

Since manual calculation is complex due to compounding, the online PPF calculator automates this instantly, saving you from errors.
