What Is a 529c Plan?
A 529c plan (usually called simply a 529 plan) is a tax-advantaged education savings plan designed to help families save for college and other educational expenses. There are two types:

This calculator focuses on investment-based 529 plans, where savings grow over time and can be withdrawn tax-free for qualified educational expenses.

How to Use the 529c Calculator
Using the calculator is simple and only requires a few inputs.
Step-by-Step Instructions:
- Enter Current Savings
The amount already saved in your 529c plan. - Enter Monthly or Annual Contribution
How much you plan to contribute regularly. - Input Number of Years Until College
Typically 0–18 years depending on the child’s age. - Expected Rate of Return (%)

The tool returns:- Future Value of your 529c plan
- Total contributions made
- Interest or investment gain earned
Formula Used (Plain Text)
Future Value of 529 Savings (with regular contributions):
FV = P(1 + r)^t + PMT × [((1 + r)^t – 1) / r]
Where:
- FV = Future Value
- P = Initial principal (current savings)
- PMT = Regular monthly contribution
- r = Annual return rate ÷ 12 (for monthly contributions)
- t = Time in years × 12 (converted to months)
This formula considers compounding growth and recurring contributions.
Example Calculation
- Current Savings: $5,000
- Monthly Contribution: $300
- Years to College: 10
- Expected Annual Return: 6%
r = 0.06 ÷ 12 = 0.005
t = 10 × 12 = 120 months
FV = 5000 × (1 + 0.005)^120 + 300 × [((1 + 0.005)^120 – 1) / 0.005]
Future Value ≈ $5,000 × 1.8194 + $300 × 186.282
FV ≈ $9,097 + $55,885 = $64,982
Result: Your 529c account will be worth approximately $64,982 after 10 years.
