529 Plan Growth Calculator
What Is a 529 Plan?
A 529 plan is a tax-advantaged savings plan designed to encourage saving for future education costs. Named after Section 529 of the Internal Revenue Code, these plans can be used to pay for qualified education expenses including tuition, books, and even some K–12 costs.
Two major types of 529 plans exist:
- Prepaid tuition plans
- Education savings plans (our calculator is tailored to this type)
About the 529 Plan Growth Calculator
The 529 Plan Growth Calculator is a web-based tool that allows you to project the future value of your 529 savings based on four key inputs:
- Initial investment
- Monthly contribution
- Annual interest rate
- Number of years until withdrawal
With this calculator, you can explore "what-if" scenarios—such as increasing your monthly contribution or estimating how long your savings will last under various interest rate assumptions.
How to Use the Calculator: Step-by-Step
Using the 529 Plan Growth Calculator is incredibly straightforward. Here’s how to make the most of it:
- Enter Your Initial Investment
Input the amount you’ve already saved or plan to invest at the start. Example: $5,000 - Enter Monthly Contributions
Specify how much you plan to contribute each month going forward. Example: $200 - Input Annual Interest Rate
Enter your expected average annual return as a percentage (e.g., 6%). This field assumes compounding interest. - Set the Number of Years
Indicate how many years you plan to keep the money invested before making withdrawals (e.g., 15 years). - Click “Calculate”
Hit the Calculate button to see the projected Future Value of your 529 plan. - Reset Anytime
Use the Reset button to clear all fields and start fresh.
Practical Example: Saving for a Newborn’s College Fund
Let’s say you just had a baby and want to start saving immediately. You decide to:
- Invest an initial $5,000
- Contribute $300 per month
- Assume an average annual return of 6%
- Save for 18 years
Plugging these values into the calculator gives you a future value of approximately $130,000.
This can go a long way toward covering tuition, books, housing, and more—especially when invested wisely.
