How to Save for College: 529 Plans, Timelines, and How Much You Need

Four-year college costs at public in-state universities average over $28,000/year in 2026 (tuition, fees, room, and board). Private universities average over $60,000/year. Without a savings plan, families face a choice between large student loans, significant income disruption at college age, or limiting options, which is why most families should start saving as early as they realistically can. Understanding how to save for college early with tax-advantaged accounts can significantly reduce the burden of these escalating costs.

Quick answer

For most families, a 529 plan is the right tool, because contributions grow tax-free, qualified withdrawals are tax-free, and many states add a deduction on top. The biggest lever is not which specific plan you choose, it is when you start: funding a $50,000 target costs about $145 a month from birth versus roughly $960 a month starting at age 14, since compounding has so much less time to work. Use your own state's plan first if it offers a real deduction; otherwise shop nationally for lower fees. Unused funds can move to another family member or, within limits, roll into a Roth IRA.

How Much to Save

A common target: save enough to cover 1/3 of expected college costs, with the remaining 2/3 funded by financial aid, scholarships, and the student's contributions (income during college, loans if necessary).

Monthly savings needed to cover $50,000 in future college costs (one child, assumed 6% investment return):

The cost of waiting is dramatic. Starting at birth costs a third of what starting at age 14 costs for the same outcome. Run your own child's age and target amount through the College Savings Calculator instead of relying on the generic table above.

What to Do at Each Stage

529 Plans: The Primary Tool

A 529 plan is a state-sponsored investment account for education savings. Key features:

Tax benefits: Contributions are made with after-tax dollars. Investment growth is tax-free. Withdrawals for qualified education expenses (tuition, fees, room and board, books, computers) are tax-free federally and in most states.

State tax deductions: Most states offer a deduction or credit for contributions to their own state's 529 plan. The deduction can be worth $100–600/year on a $3,000–5,000 contribution depending on your state and tax rate.

Flexibility: Funds can be used at any accredited U.S. college or university, many trade and vocational schools, and some foreign universities. Unused funds can be transferred to another family member (sibling, cousin, yourself). Federal law also allows up to $35,000 in unused 529 funds to be rolled into a Roth IRA for the beneficiary over time, subject to conditions including a 15-year account-age requirement and annual Roth contribution limits.

Control: The account owner (usually a parent) controls the funds, not the beneficiary. You can change the beneficiary at any time. Model your own contribution and time horizon directly in the 529 Plan Calculator to see the projected tax-free growth.

How to Open a 529

1. Choose a plan: Start with your state's plan if it offers a meaningful tax deduction. Compare fees and investment options at SavingForCollege.com.
2. Open the account: Most plans open online in 20 minutes. Provide Social Security numbers for both owner (parent) and beneficiary (child).
3. Choose investments: Most plans offer age-based portfolios that automatically shift from aggressive (stocks) to conservative (bonds) as college approaches. This is the right default for most families. In the final year or two before enrollment, many families move the imminent-use portion into cash equivalents like a high-yield savings account, currently paying up to 4.20%, rather than leaving tuition money exposed to a market downturn right before it is due.
4. Set up automatic contributions: Monthly automated transfers are the most consistent approach. $100–300/month from birth is more achievable than lump sums.

Other College Savings Options

Roth IRA: Contributions (not earnings) can be withdrawn penalty-free for any purpose. Some families use a Roth IRA as a dual-purpose retirement/college savings account. If college funds are not needed, the money stays for retirement. Note: using a Roth for college prevents those funds from compounding for 30+ years of retirement.

Coverdell ESA: Lower contribution limit ($2,000/year), but can be used for K-12 expenses as well as college. Rarely used today given 529's expanded K-12 eligibility and higher limits.

Taxable brokerage account: No tax advantages, but maximum flexibility. Consider for large savers who have maximized 529 contributions.
