1. What is the Savings Calculator?

The Savings Calculator estimates the future value of investments with regular monthly contributions. It calculates how much your savings will grow over time with compound interest, helping you plan for financial goals.

2. How Does the Calculator Work?

The calculator uses the compound interest formula with regular contributions:

\[ FV = P \times (1 + r / 12)^{(12 \times t)} + PMT \times \frac{(1 + r / 12)^{(12 \times t)} - 1}{r / 12} \]

Where:

$ FV $ — Future value of the investment ($)
$ P $ — Initial principal amount ($)
$ r $ — Annual interest rate (decimal)
$ t $ — Time in years
$ PMT $ — Monthly payment amount ($)

Explanation: The formula calculates compound interest on both the initial principal and regular monthly contributions, showing how savings grow over time.
