What is a PPF Calculator?
A PPF Calculator (Public Provident Fund Calculator) is a useful online tool that helps individuals estimate the total amount they will receive upon maturity of their PPF investment. It calculates the total invested amount, interest earned, and the final maturity value based on the annual investment, the prevailing or custom interest rate, and the investment tenure—typically 15 years.
Public Provident Fund is a long-term savings scheme launched by the Government of India that offers tax benefits under Section 80C of the Income Tax Act and guarantees returns backed by the government. It is a safe, reliable, and low-risk investment option favored by salaried individuals, freelancers, and small business owners.
How Does the PPF Calculator Work?
The calculator takes three primary inputs:
-
Annual Investment Amount – You can invest a minimum of ₹500 and a maximum of ₹1.5 lakh per financial year.
-
Interest Rate – The current interest rate is revised quarterly by the Ministry of Finance. Our calculator also lets you input a custom rate for better flexibility.
-
Investment Tenure – Typically 15 years, but extendable in blocks of 5 years.
The calculator uses a compound interest formula with yearly compounding to determine the maturity amount:
A = P * [((1 + r)^n – 1) / r]
Where:
-
A is the maturity amount
-
P is the yearly contribution
-
r is the annual interest rate divided by 100
-
n is the number of years
Why Use a PPF Calculator?
A PPF calculator is especially helpful if you are:
-
Planning your long-term savings and retirement
-
Comparing PPF with other tax-saving schemes like ELSS or NPS
-
Unsure how interest rates impact the final maturity amount
-
Interested in knowing how a higher contribution or tenure changes the results
Instead of doing manual calculations, the calculator instantly gives you accurate figures for:
-
Total principal invested
-
Total interest earned over the tenure
-
Final maturity amount
This helps you plan your finances more efficiently.
