1. What is a PPF Calculator With Yearly Increment?

Definition: This calculator estimates the maturity value of a Public Provident Fund (PPF) account where annual deposits increase by a fixed percentage each year.

Purpose: It helps investors plan their PPF investments when they intend to increase their contributions annually.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Maturity = \sum_{k=1}^{n} \left( P \times (1 + g)^{k-1} \right) \times (1 + i)^{n - k + 1} \]

Where:

$ Maturity $ — Final maturity amount ($)
$ P $ — Initial annual deposit ($)
$ g $ — Yearly deposit growth rate (decimal)
$ i $ — PPF interest rate (decimal, default 0.071)
$ n $ — Investment period (years)
$ k $ — Current year in calculation

Explanation: Each year's deposit grows by rate g, and each deposit compounds until maturity at rate i.

3. Importance of PPF Calculation

Details: Accurate PPF projections help with retirement planning, tax-saving strategies, and long-term wealth accumulation.

4. Using the Calculator

Tips: Enter initial deposit, yearly growth rate (e.g., 0.10 for 10%), investment period (typically 15 years for PPF), and current interest rate (default 7.1%).
