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

Bottom line: A 529 plan is the right tool for most college savers. Contributions grow tax-free and withdrawals for qualified education expenses are tax-free. Most states offer additional deductions on contributions. Start as early as possible — a child born today has 18 years of compounding before college bills arrive.

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.

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.

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). As of 2024, up to $35,000 in unused 529 funds can be rolled into a Roth IRA for the beneficiary (subject to conditions).

Control: The account owner (usually a parent) controls the funds, not the beneficiary. You can change the beneficiary at any time.

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.
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.
