What Is a 529 Savings Plan?

The Formula Behind the Calculator

Our 529 Savings Plan Calculator uses a compound interest formula that accounts for both your initial savings and recurring monthly contributions.

Here’s the formula it follows:

Future Value of Savings = Current Savings × (1 + Monthly Interest Rate)^Months + Σ(Monthly Contribution × (1 + Monthly Interest Rate)^(Months - i))

Where:

  • Current Savings: The amount you already saved.
  • Monthly Contribution: The amount you will contribute every month.
  • Annual Interest Rate: The expected yearly growth rate of your savings.
  • Months: Total months until college (Years × 12).
  • i: Month number in the contribution sequence.

This formula ensures that your contributions compound over time, which can significantly increase the total savings for college.


Example Calculation

Let’s walk through a practical example to understand how the calculator works.

Scenario:

  • Current Savings: $5,000
  • Monthly Contribution: $200
  • Annual Interest Rate: 6%
  • Years Until College: 10

Step 1: Convert Annual Interest to Monthly Interest
Monthly Interest Rate = 6% ÷ 12 = 0.5% = 0.005

Step 2: Total Months Until College
10 years × 12 months = 120 months

Step 3: Calculate Future Value of Current Savings
FV of current savings = $5,000 × (1 + 0.005)^120 ≈ $9,116.30

Step 4: Calculate Future Value of Monthly Contributions
Using the formula:
FV of contributions = Σ($200 × (1 + 0.005)^(120 - i)) ≈ $34,828.20

Step 5: Total Estimated Savings
Total Future Savings = $9,116.30 + $34,828.20 ≈ $43,944.50

This means that in 10 years, with a $200 monthly contribution and 6% annual growth, you could have nearly $44,000 for college.

Years Until CollegeMonthly ContributionTotal Savings (6% Interest)
5$100$7,000
5$200$14,000
10$100$22,000
10$200$44,000
15$100$38,500

This table demonstrates how consistent contributions and compounding interest can grow your savings over time. Even small monthly contributions can make a significant difference in the long run.
