1. What is the Monthly Saving Calculator?

The Monthly Saving Calculator With Interest helps you calculate the future value of your savings by considering both an initial principal amount and regular monthly contributions, compounded monthly at a specified annual interest rate.

2. How Does the Calculator Work?

The calculator uses the future value formula:

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

Where:

$ FV $ — Future Value ($)
$ P $ — Initial Principal ($)
$ PMT $ — Monthly Payment ($/month)
$ r $ — Annual Interest Rate (decimal)
$ t $ — Time in Years (years)

Explanation: The formula calculates compound interest on both the initial principal and regular monthly contributions, compounded monthly.

3. Importance of Future Value Calculation

Details: Understanding the future value of your savings helps in financial planning, retirement planning, and achieving long-term financial goals by showing how regular contributions and compound interest can grow your money over time.

4. Using the Calculator

Tips: Enter initial principal in dollars, monthly payment in dollars per month, annual interest rate as a percentage, and time in years. All values must be non-negative with time greater than zero.
