PPF Calculator Formula

The PPF Calculator estimates the maturity value of your investment based on your annual contribution, investment tenure, and applicable interest rate. The result depends on when contributions are deposited and how interest is calculated.

Annual Contribution

Annual Contribution = Amount * Periods per Year

Year-end Balance

Closing = (Opening + Annual Contribution) * (1 + Rate / 100)

Total Deposits

Total Investment = Annual Contribution * Years

Maturity Value

Maturity = Total Investment + Total Interest

Test Case

However, the maturity value and interest figure must be verified against the calculator's actual formula. Do not retain these as confirmed results merely because they appear in the written task.

Annual Contribution vs Monthly Contribution in PPF

Both contribution methods are eligible for the same PPF tax benefits and annual investment limit. The difference lies in when the money is deposited and how long it remains invested during the financial year.

Which Option Should You Choose?

An annual contribution made early in the financial year may earn more interest since the full amount remains invested for longer. Monthly contributions are easier to manage and help build a regular savings habit. Use the calculator to compare different contribution amounts and their impact on your maturity value.

PPF Tax Benefits Under Section 80C

PPF investments may qualify for tax deductions of up to ₹1.5 lakh per tax year under Section 123 read with Schedule XV of the Income-tax Act, 2025, subject to applicable conditions and tax regime.

PPF follows the Exempt-Exempt-Exempt (EEE) tax structure, where contributions, interest earned, and maturity proceeds are tax-free as per applicable rules.

PPF Withdrawal & Loan Rules

PPF is designed as a long-term savings scheme, but it also provides limited access to funds during the investment period through loans and partial withdrawals.

These provisions offer some flexibility while helping investors stay committed to their long-term savings goals.

PPF Extension After 15 Years

A PPF account matures after 15 years. After maturity, it can be extended in blocks of five years while continuing to earn interest on the accumulated balance.

You can choose either of the following options:

• Extend with contributions – Continue making deposits and earn interest on both your existing balance and future contributions.
• Extend without contributions – Keep the account active and earn interest on the existing balance without making additional deposits.

To continue making contributions after maturity, the required extension request must be submitted within the prescribed time period. This option allows your savings to remain invested and continue compounding beyond the original tenure.
