Introduction
The PPF Calculator Tool helps you estimate the maturity amount, interest earned, and total investment for your Public Provident Fund (PPF) contributions. It simplifies the complex calculations required for PPF investments and provides insightful charts for a better understanding of your financial growth over time.
How to Use the PPF Calculator Tool
Follow these steps to calculate your PPF maturity value:
1. Enter Your Yearly Investment
- Field Name: Yearly Investment (₹)
- Input Range: ₹500 to ₹1,50,000
- Default Value: ₹1,50,000
- Adjust the slider or manually enter the yearly amount you plan to invest in your PPF account.
2. View the Current PPF Interest Rate
- Field Name: Current PPF Interest Rate (%)
- Default Value: 7.1%
- This field is pre-filled and reflects the current PPF interest rate as declared by the government. It cannot be edited.
3. Enter Investment Duration
- Field Name: Duration of Investment (Years)
- Input Range: 15 to 30 years
- Default Value: 15 years
- Enter the number of years you plan to continue investing in the PPF scheme.
Results
Once all fields are filled, the tool will display the following results dynamically:
1. Invested Amount
- The total amount you have invested over the chosen duration.
- Formula: Invested Amount = Yearly Investment × Duration
2. Total Interest
- The total interest earned on your PPF contributions over the chosen duration.
- Formula: Total Interest = Maturity Amount − Invested Amount
3. Maturity Amount
- The total amount you will receive at the end of the investment period, including principal and interest.
- Formula:
$$\text{Maturity Amount} = \text{Yearly Investment} \times \left( \frac{\left(1 + \text{Interest Rate}\right)^\text{Duration} - 1}{\text{Interest Rate}} \right) \times \left(1 + \text{Interest Rate}\right)$$
Charts for Visualization
The tool includes two interactive charts to visualize your investment details:
1. Pie Chart: Investment Breakdown
- Displays the proportion of total investment vs. total interest earned.
2. Line Chart: Growth Projection Over Time
- Plots the growth of your PPF investment over the chosen duration.
- X-Axis: Years
- Y-Axis: Amount (₹)
Features

Tips

- Consider Long-Term Investments: PPF is a long-term investment tool. Opting for a longer duration (e.g., 20–30 years) can significantly increase your maturity amount due to compound interest.
- Revisit Interest Rates: Keep track of government announcements as PPF interest rates may change periodically.
