How to Save for Your Kids' College: What Every Parent Should Do

Why Starting Early Matters So Much

Time is your greatest asset when saving for college. The difference between starting at birth vs. age 10 is dramatic. Saving $300/month from birth (18 years) at 7% annual growth yields approximately $131,000. Starting at age 10 (8 years) with the same contribution yields only $40,000. Compound growth works in your favor when you start early, but it still works even if you start late — every dollar saved reduces the amount your child will need to borrow.

Step 1: Secure Your Retirement First

Before aggressively saving for college, ensure you're contributing enough to your retirement accounts to at least capture any employer 401k match. Your retirement savings can't be funded with loans; your child's college can be. If you have to choose between your retirement and their college, retirement comes first.

Step 2: Open a 529 Plan

A 529 plan is the best tool for most families saving for college. Open one as soon as you know the child's Social Security number — at birth if possible. Key setup decisions:

• Which state's plan? If your state offers a tax deduction for in-state contributions, start there. Otherwise, choose a low-cost plan from Utah (my529), New York, or plans through Vanguard or Fidelity.
• Investment selection: Choose an age-based portfolio or a low-cost index fund. Avoid high-fee actively managed options.
• Contribution amount: Even $50–$100/month at birth builds a meaningful fund over 18 years.

Step 3: Calculate How Much You Need

The current average cost of a 4-year public in-state education (tuition, fees, room, and board) is approximately $108,000. Assuming 4% annual inflation in college costs, that becomes about $240,000 for a child born today by the time they enroll. That's a big number, but you don't need to cover 100% of it from savings — the traditional guideline is the Rule of Thirds: save one-third, count on scholarships/aid for one-third, and cover the final third with current income or modest loans.

How Much to Save Monthly by Age

To accumulate $80,000 (one-third of projected cost) assuming 6% annual returns:

• Starting at birth (18 years): ~$214/month
• Starting at age 5 (13 years): ~$369/month
• Starting at age 10 (8 years): ~$703/month
• Starting at age 14 (4 years): ~$1,573/month

Starting earlier dramatically reduces the monthly contribution required to reach the same goal.

Other Accounts to Consider

Beyond 529 plans, Coverdell ESAs offer more investment flexibility with a $2,000/year contribution limit. UGMA/UTMA custodial accounts are more flexible (money can be used for anything) but assets count more heavily against financial aid than 529 plans. Roth IRAs can also be used for college expenses in a pinch, as contributions (not earnings) can be withdrawn tax and penalty-free at any time.

Ask Family to Contribute

Instead of toys or gifts, grandparents and relatives can contribute to the child's 529 plan. Many 529 plans have gift contribution portals. Grandparent-owned 529 plans used after a student's second year of college are no longer penalized on FAFSA calculations (as of the updated FAFSA rules starting 2024–25).

What If You Can't Save Much?

Save what you can, even $25–50/month. Every dollar saved reduces loan burden. Discuss with your child that they'll need to contribute — through scholarships, work, and potentially starting at community college. Having the conversation early helps the child take ownership of their educational decisions with cost in mind.
