When my first kid was born, someone told me to open a 529 plan. I nodded, said "yeah totally," and then didn't do it for 18 months because I had no idea which one to pick.
There are over 100 different 529 plans. Every state has at least one. Some are great. Some charge fees that eat your returns alive. The difference between a good plan and a bad one can cost you tens of thousands of dollars over 18 years.
I spent a weekend comparing them so you don't have to. Here's what matters.
The short answer
If your state gives you a tax deduction for 529 contributions, use your state's plan first. If not (or if your state's plan is expensive), use Utah's my529 or Nevada's Vanguard 529. They have the lowest fees and best investment options in the country.
How much should you save?
Plug in your kid's age and we'll tell you how much to put away each month.

Do you even need a 529?
If you plan to help pay for your kid's college, yes. The tax benefits are real. Your money grows tax-free, and withdrawals for education expenses are tax-free too Source: IRS Publication 970, Tax Benefits for Education . That's a better deal than a regular brokerage account where you'd pay capital gains tax on the growth.
How much difference does that make? If you invest $300/month for 18 years at a 7% return, you'll have about $130,000. In a taxable account, you'd owe roughly $10,000-15,000 in capital gains tax on that growth. In a 529, you owe $0. That's a free semester of college just from the tax benefit.
What if my kid doesn't go to college?
This used to be a real concern. Starting in 2024, you can roll unused 529 funds into a Roth IRA Source: SECURE 2.0 Act, Section 126 for the same beneficiary, up to $35,000 lifetime. So if your kid gets a scholarship, goes to trade school, or skips college entirely, the money isn't trapped. It becomes retirement savings.
You can also change the beneficiary to another family member at any time. Second kid, niece, nephew, even yourself if you want to go back to school.
How much should you save?
The average cost of 4 years at a public university is about $110,000 including room and board Source: College Board, Trends in College Pricing 2025 . For private universities, it's over $230,000. Those numbers go up every year.
You don't have to cover 100%. Even saving 50-70% puts your kid in a massively better position than most. Use the 529 calculator to see what monthly contribution gets you to your target.
