529 Plans Explained: How to Start Saving for College

The average cost of a four-year public university education is currently over $100,000 — and it continues to rise faster than inflation. Starting to save when your child is a newborn gives you the single most powerful advantage in college funding: time. Even modest monthly contributions grow significantly over 18 years thanks to compound returns.

This guide demystifies 529 plans, explains your options, and helps you start a savings strategy that fits your budget — whether that's $25 a month or $500.

Why 529 Plans Are the Best College Savings Tool

529 plans are state-sponsored investment accounts specifically designed for education expenses. They offer three major tax advantages: contributions grow tax-free, withdrawals for qualified education expenses are tax-free at the federal level, and many states offer income tax deductions or credits for contributions. No other savings vehicle offers this combination of benefits for education.

As of 2024, the SEC notes that 529 plans can now be used for more than just college. Qualified expenses include K-12 tuition (up to $10,000/year), apprenticeship programs, and student loan repayment (up to $10,000 lifetime). Recent legislation also allows unused 529 funds to be rolled into a Roth IRA for the beneficiary (subject to conditions), reducing the risk of "oversaving."

How 529 Plans Work

You open an account, name a beneficiary (your child), and choose investment options (typically age-based portfolios that automatically become more conservative as the child approaches college age). Anyone can contribute — parents, grandparents, aunts, uncles, friends. Contributions are made with after-tax dollars (no federal deduction), but the growth and withdrawals are tax-free for qualified expenses.

Qualified expenses include: tuition and fees, room and board (up to the school's cost of attendance for off-campus housing), books and supplies, computers and internet access, and special needs equipment.

Choosing a 529 Plan

You can use any state's 529 plan regardless of where you live or where your child goes to school. However, your state's plan may offer tax benefits (like a state income tax deduction) that make it more advantageous. Check whether your state offers a tax deduction first. If your state has no income tax or no 529 tax benefit, compare plans based on fees, investment options, and performance.

Key factors to compare: expense ratios (look for under 0.5%), investment options (age-based portfolios are simplest), minimum contribution requirements, and state tax benefits.

How Much to Save

The "right" amount depends on your goals and budget. A common target is to save enough to cover about 1/3 of projected college costs, with the remaining 2/3 coming from current income, financial aid, scholarships, and student contributions. For a public university, that means saving roughly $50,000–$75,000 by age 18.

Reaching $50,000 by age 18 takes roughly $130 a month if you start at birth, and roughly $360 a month if you start at age ten — the same target, nearly triple the monthly cost, purely because of when you began. The figures below assume a 7% average annual return, which is an illustration rather than a promise; actual returns vary and can be negative in any given year.

Even if you can't hit these targets, any amount helps. $25/month from birth grows to approximately $10,800 — that's a full year of community college tuition. The most common mistake is waiting until the number feels meaningful; the table above is the argument against that.

Alternatives to 529 Plans

A 529 is not the only tax-advantaged account a child can hold. Trump Accounts for kids covers the newer option and how it sits alongside a 529, including who can contribute and what the money can eventually be used for.

This page is general information, not financial advice. Contribution limits, state deductions, and eligibility rules change, and the right mix depends on your own tax situation — worth an hour with a fee-only advisor before you commit to a structure.

Where College Savings Sits in the Wider Budget

College is the most distant line item on a new parent's budget and, for that reason, usually the last one funded. That order is mostly correct — but it is worth knowing the size of everything ahead of it before you decide what is left over. The cost of raising a baby sets out the first-year numbers, and budgeting for a new baby turns them into a monthly plan.

The two expenses that most often crowd out college saving are childcare and a second child. Childcare options compares what each arrangement actually costs, and going from one child to two covers what changes financially when the second arrives. If grandparents keep asking what to give, a 529 contribution is a request that fits naturally alongside a registry.
