How Much Should You Save for Your Kid's College?

The Number That Scares Parents — And Why It Shouldn't

If you have a baby today and college costs rise at just 3% annually, four years at a public university could cost roughly $220,000 by the time your child enrolls. A private university? Closer to $466,000. Those figures land like a punch to the stomach — and they're designed to. But reacting to a worst-case sticker price without understanding the full picture is exactly how parents end up either over-saving at the expense of their own retirement or freezing entirely and saving nothing.

The real question isn't "how do I accumulate $400,000?" It's more nuanced: how much of the projected bill are you actually choosing to fund, when are you starting, and what tools are you using to get there? Whether you're a new parent just getting started or someone asking how much to invest for beginners in the college-savings context, this guide gives you a framework built on real numbers — not fear.

What College Actually Costs: Published Price vs. Net Price

The College Board's figures for the 2025–2026 academic year are a useful anchor. Average published tuition and fees at a public four-year in-state university sit at $11,950 per year. Add housing, food, books, transportation, and other expenses, and the total annual student budget climbs to roughly $31,000. For private nonprofit universities, published tuition and fees average $45,000, with a total annual budget of around $65,470.

Four years at today's prices: approximately $124,000 at a public university and $262,000 at a private nonprofit.

But here's what most parents miss: those are published prices. The net price — what families actually pay after grants, scholarships, and tax benefits — is often dramatically lower. The College Board estimates that first-time, full-time students at public four-year schools pay an average of just $2,300 in net tuition and fees after grant aid and tax benefits. Room, board, and living costs still apply, but the tuition itself can be near zero for many families.

Private universities can discount heavily too. Some elite private schools with large endowments routinely offer packages that make them cheaper than in-state public schools for middle-income families. The lesson: never multiply a sticker price by four and call it your savings target.

Before building a savings plan, clarify two things:

• What type of school are you realistically planning for — public in-state, private nonprofit, community college first?
• What percentage of the projected cost are you actually willing to cover?

Choosing Your Coverage Percentage — A Smarter Starting Point

The better question isn't "how do I save enough for college?" It's "how much of college am I choosing to fund?" That reframe matters because college is a shared funding problem, not a single parent-funded transaction.

Using the projected public university bill of roughly $220,721 (today's $31,000 annual budget grown at 3% over 18 years), here's what different coverage targets look like:

• 25% coverage: ~$55,180
• 50% coverage: ~$110,361
• 75% coverage: ~$165,541
• 100% coverage: ~$220,721

None of these is the "right" answer. Your child may earn merit scholarships. They might attend a community college for two years and transfer. They might live at home. They might work part-time. You might cash-flow a portion of tuition from your income while they're enrolled. Grandparents might contribute. All of these reduce what your 529 actually needs to produce.

The critical insight: setting a coverage target based on your household's actual financial capacity is more sustainable — and ultimately better for your child — than chasing a $400,000 number that leaves you broke at 65.

What That Means Per Month: The Math on Starting Early

Vanguard's projections, assuming a 5% annual return, make the time-value argument clearer than any motivational speech:

For a $100,000 target:

• Start at birth: ~$285/month
• Start at age 5: ~$454/month
• Start at age 10: ~$846/month

For a $200,000 target:

• Start at birth: ~$570/month
• Start at age 10: ~$1,692/month

Starting early doesn't require saving a large amount — it requires giving smaller contributions more time to compound. As a concrete example: $250 per month invested for 18 years at 5% grows to roughly $87,300. You personally contributed $54,000. Investment growth added another $33,300. Time did roughly 38% of the saving for you.

For anyone exploring how much to invest as a beginner in the college-savings space, this is the core takeaway: start smaller and start sooner, rather than waiting until you can afford to start big. A $50/month contribution started at birth beats a $300/month contribution started at age 10, both financially and psychologically.

If your budget is tight right now, automate $50 or $100 and increase it annually as your income grows. The worst college savings strategy isn't starting small — it's waiting until the numbers feel less overwhelming, which they rarely do.

The 529 Plan: Why It's Usually the Right Account

For money you genuinely intend to use for education, the 529 plan is the most efficient vehicle available to most families. Here's why it beats a standard brokerage account or custodial account for this specific purpose:

Tax advantages:

• Contributions grow tax-deferred inside the account
• Qualified withdrawals are federal income tax-free
• Many states offer a deduction or credit on contributions — worth checking for your specific state

Control: Unlike a custodial account (UGMA/UTMA), a 529 remains under parental control. A custodial account is an irrevocable gift — once your child reaches legal age, it's their money, full stop. You might mentally label it "college fund." Your 18-year-old might mentally label it "gap year in Europe."

Financial aid treatment: Under the federal FAFSA formula, assets in a parent-owned 529 are assessed far more favorably than assets held directly in a student's name. Student-owned assets are assessed at 20%. Parent-owned assets, including a parent-owned 529, go through a more favorable formula — often cited as up to approximately 5.64%, though the actual calculation depends on the family's complete financial picture.

The "what if they don't go to college" problem has largely been solved:

Modern 529 rules are far more flexible than most people realize:

• Funds can be used for registered apprenticeships and certain post-secondary credentialing programs
• Up to $10,000 lifetime can go toward qualified student loan repayment
• Starting in 2026, up to $20,000 per year per beneficiary can be used for K–12 expenses (up from the prior $10,000 limit)
• Beneficiary can be changed to another qualifying family member without tax consequences
• Under current rules, up to $35,000 in unused 529 funds can be rolled into a Roth IRA for the beneficiary (subject to conditions: account must be open at least 15 years, annual IRA contribution limits apply, and contributions from the prior 5 years are generally ineligible)

That Roth IRA rollover option is the most meaningful change to 529 flexibility in years. It doesn't mean you should deliberately over-fund a 529 as a Roth strategy — the rules are too restrictive for that — but it does mean that being slightly overfunded no longer carries the same penalty risk it once did.

The Rule No Financial Calculator Will Tell You: Retirement First

This is where the math and the emotion collide. Most parents instinctively want to sacrifice everything for their children's futures. That instinct is admirable. The financial outcome of acting on it uncritically can be devastating — for both parent and child.

Here's the sequencing that holds up under scrutiny:

1. High-interest debt first — paying down 20%+ credit card debt is a guaranteed return that no 529 investment can reliably beat
2. Emergency fund — three to six months of expenses before locking money away in investment accounts
3. Employer 401(k) match — this is an immediate 50–100% return on contribution, depending on the match structure. Do not leave it on the table to fund a 529
4. Retirement savings — IRA, 401(k) beyond the match, other retirement vehicles
5. College savings — after the above are addressed, at a level your budget can genuinely sustain

The reason for this order is asymmetric: your child has access to scholarships, grants, work-study, community college, in-state tuition, and yes, federal student loans. None of those options exist for a 68-year-old who spent their working years funding private college tuition instead of a retirement account. There is no federal student loan program for retirement.

The uncomfortable truth: a parent who depletes their retirement savings to fund college may ultimately become a financial burden on the very children they were trying to help. Promising a realistic contribution and delivering it is worth more than promising unlimited funding and falling short.

Building a College Savings Plan That Actually Works

If you're starting from scratch, here's a practical framework:

• Define your target school type — public in-state, private, or undecided
• Pick a coverage percentage you can realistically commit to (50% is a reasonable starting point for many families)
• Calculate your monthly contribution using your timeline and a conservative return assumption (5% is widely used)
• Open a 529 in your state and check whether your state offers a contribution deduction or credit — it often makes sense to use your home state's plan first
• Automate contributions — even $100/month at birth compounds meaningfully by age 18
• Revisit annually — adjust contributions as income grows, and shift the investment mix toward more conservative allocations as college approaches
• Don't let perfect be the enemy of started — a small, consistent contribution today outperforms a large, theoretical contribution you never make

College savings is not a single decision made once. It's a 18-year plan that gets recalibrated as your income grows, your child's interests clarify, and the higher education landscape evolves. Build the foundation, automate it, and adjust — rather than paralysing yourself over a projected six-figure number.

Frequently Asked Questions

How much should I save per month for my child's college? It depends on your target amount and how early you start. Vanguard's projections (assuming 5% annual returns) suggest that saving $285/month from birth reaches roughly $100,000 by age 18. Wait until age 10 and the same target requires about $846/month. Starting early is significantly more cost-effective than starting large.

Is a 529 plan the best account for college savings? For most families, yes. A 529 offers tax-deferred growth, federal income tax-free qualified withdrawals, favorable treatment under the FAFSA formula compared to student-owned assets, and parental control that custodial accounts don't provide. Recent rule changes — including the Roth IRA rollover option and broader eligible expenses — have made 529s considerably more flexible than they used to be.

Should I fund a 529 or my retirement account first? Retirement first, in most cases. You cannot borrow to fund your retirement, but your child has access to grants, scholarships, work-study, and federal student loans. The recommended sequence is: eliminate high-interest debt, build an emergency fund, capture any employer 401(k) match, fund retirement accounts, then allocate to college savings.

What if my child doesn't go to college — will I lose the 529 money? Not necessarily. Modern 529 rules allow funds to be used for registered apprenticeships, certain credentialing programs, K–12 tuition (up to $20,000/year starting 2026), and student loan repayment (up to $10,000 lifetime). You can also change the beneficiary to another qualifying family member. Under current rules, up to $35,000 in unused funds can be rolled into a Roth IRA for the beneficiary, subject to eligibility conditions including a 15-year minimum account age.

What percentage of college costs should parents aim to cover? There's no universal answer. A common planning approach is to target 50% of projected costs and rely on a combination of scholarships, financial aid, student contributions, and cash flow during college years to cover the rest. Targeting 100% only makes sense if your retirement is fully funded and you have no high-interest debt — and even then, it may not be necessary given the multiple other funding sources available to students.
