Formula & Mathematical Explanation

\displaystyle F = P \times \left[ \frac{(1 + r)^n - 1}{r} \right] \times (1 + r)

PPF interest is compounded annually. Assuming contributions are made at the beginning of each financial year, the future value (F) is calculated using the annuity due formula on the annual investment (P), rate (r), and number of years (n).
