1. What is the College 529 Calculator Monthly Contribution?

The College 529 Calculator Monthly Contribution helps determine the monthly savings needed in a 529 college savings plan to reach a specific future value. It uses the future value of an ordinary annuity formula to calculate required monthly contributions based on target amount, interest rate, and time period.

2. How Does the Calculator Work?

The calculator uses the future value formula:

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

Rearranged to solve for PMT:

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

Where:

$ FV $ — Future Value (USD)
$ PMT $ — Monthly Contribution (USD/month)
$ r $ — Monthly Interest Rate (decimal)
$ n $ — Number of Months

Explanation: This formula calculates the fixed monthly payment needed to reach a specific future value, considering compound interest over time.

3. Importance of Monthly Contribution Calculation
