What you actually need to save depends on which college, when, and how much you're willing to borrow
There is no single "right" number for college savings because the cost depends on choices you haven't made yet. A public in-state university costs roughly half what a private university costs. Community college costs a fraction of either. Your child might attend at 18 or 25. You might pay the full bill, cover half, or expect your child to work and borrow. The math changes completely based on these decisions.
The practical approach is to work backward from a realistic scenario, then save what you can toward that target. If you save less, your child borrows more or attends a lower-cost school. If you save more, you have options. The goal is not a magic number—it's having enough choices when the time comes.
Key Takeaways
- Current costs for four years range from roughly $100,000 at public in-state universities to $250,000 or more at private universities, and these amounts grow each year.
- Saving even a partial amount—say, half the expected cost—meaningfully reduces how much your child needs to borrow or work.
- Starting early matters because time lets smaller monthly contributions grow through compound interest, not because you must hit a specific target.
- A 529 plan or Coverdell ESA offers tax advantages, but a regular savings account works if those accounts don't fit your situation.
- Your child's income, scholarships, and willingness to attend community college first are realistic parts of the plan, not backup options.
Estimating the cost for the school your child might attend
Start by picking one or two schools you think your child might realistically attend, then look up their published cost of attendance on their website. This number includes tuition, fees, room and board, and books. It is usually listed under "Cost of Attendance" or "Financial Aid" on the admissions or financial aid page.
Multiply that annual cost by four (or however many years your child will attend). Then add roughly 3 to 5 percent per year to account for tuition increases. A school that costs $30,000 per year today will cost more in 10 years. If your child is 8 years old and will attend in 10 years, multiply the current annual cost by 1.04 raised to the 10th power to get a rough future cost. Most financial calculators do this automatically.
Do this for two scenarios: a public in-state school and a private school, or a community college and a four-year university. You will see the range. Your target is somewhere in that range, depending on how much you want to cover.
Deciding what portion you want to fund
You do not have to save the full amount. Many families save enough to cover half, or a third, or just the first two years. Your child can cover the rest through scholarships, work-study, part-time jobs, or student loans. There is no moral obligation to pay for all of it.
A practical middle ground: save enough to cover half the cost of a public in-state university. This reduces your child's borrowing significantly without requiring you to save an enormous amount. If your child gets scholarships or attends community college first, you have extra money. If they attend a private school, they borrow more—which is a choice they can make as an adult.
Write down your target amount. If a public in-state school costs $120,000 over four years and you want to cover half, your target is $60,000. If you want to cover 75 percent, it is $90,000. This number is your starting point for figuring out how much to save per month.
How much to save per month to reach your target
Divide your target by the number of months until your child turns 18 (or whatever age you expect them to start college). If your target is $60,000 and your child is 8 years old, you have 10 years, or 120 months. That is $500 per month before any investment growth.
But if you put that money in a savings account earning 4 to 5 percent annually, or in a 529 plan earning 6 to 8 percent through stock investments, the money grows. A financial calculator will show you the exact monthly amount needed. As a rough guide: if you invest the money and earn 5 percent annually, you need to save roughly 30 to 40 percent less per month than the simple division suggests.
If $500 per month is not realistic for your budget, save what you can. Even $100 or $200 per month adds up over 10 years, especially with investment growth. You will not hit your full target, but you will have something—and your child will have more options than if you saved nothing.
Using a 529 plan or Coverdell ESA for tax advantages
A 529 plan is a state-sponsored savings account where money grows tax-free as long as it is used for college costs. You contribute after-tax dollars, but the growth is not taxed, and withdrawals for tuition, fees, room and board, and books are not taxed either. Most states offer a 529 plan; you can use any state's plan regardless of where you live.
A Coverdell ESA works similarly but has a lower annual contribution limit ($2,000 per year, compared to much higher limits for 529 plans). It also allows withdrawals for K-12 private school tuition, which 529 plans do not.
Both accounts have investment options ranging from conservative (bonds, stable value funds) to aggressive (stock index funds). The more years until college, the more risk you can typically take. If your child is 8 years old, you might choose stock-heavy investments. If they are 16, you might shift to bonds to reduce the chance of a market downturn right before you need the money.
If a 529 or Coverdell does not fit your situation—perhaps you are unsure about your child's college plans, or you want maximum flexibility—a regular savings account or brokerage account works too. You will pay taxes on the growth, but there are no restrictions on how you use the money.
What happens if you save less than your target
Saving $30,000 instead of $60,000 is not failure. It means your child borrows $30,000 more, or works more during college, or attends community college for the first two years (which costs far less and transfers to a four-year university). These are real, workable paths.
Federal student loans for dependent students have limits, but private loans exist if needed. Work-study and part-time jobs are standard for college students. Community college is a legitimate choice, not a consolation prize—many students save money and time by starting there.
The point of saving is to give your child options, not to eliminate all borrowing or work. If you save something, you have accomplished that goal.
Adjusting your plan as your child gets older
Your estimate will change as your child ages and you learn more about their interests and academic performance. A child interested in engineering might attend a specific university; a child interested in trades might not attend a four-year university at all. Revisit your target every few years and adjust your monthly savings if needed.
As your child gets closer to college age, shift your investments toward safer options. If your child is 16 and will start college in two years, you do not want a market crash to wipe out your savings. Most 529 plans offer "age-based" investment options that automatically become more conservative as your child approaches college age.
If your child receives scholarships or decides to attend a lower-cost school, you can use the extra money for graduate school, trade school, or other education costs. Many 529 plans now allow transfers to siblings or even repayment of student loans (up to certain limits).
Frequently Asked Questions
Should I save for college before paying off my own debt?
If you are paying high-interest debt (credit cards, personal loans above 6 percent), prioritize that first. Your child can borrow for college at lower rates than you can borrow for other purposes. Once high-interest debt is gone, college savings becomes more realistic. If you have low-interest debt (mortgage, student loans below 4 percent), you can do both.
What if I have multiple children?
A 529 plan allows you to save for multiple children in one account, or open separate accounts for each. You can also transfer unused funds from one child's account to another. If you have limited budget, save proportionally for each child, or focus on the oldest first and adjust as you go.
Can my child use college savings for trade school or apprenticeships?
Most 529 plans now cover tuition and fees at trade schools and apprenticeships, not just four-year universities. Check your specific plan's rules. If your child pursues a trade instead of college, you may be able to roll the money into a sibling's account or use it for other education costs.
What if my child gets a full scholarship?
If you withdraw money from a 529 plan and it is not used for college costs, you pay taxes on the growth plus a 10 percent penalty. However, many plans now allow penalty-free withdrawals if your child receives a scholarship—you pay taxes on the growth but not the penalty. Check your plan's rules before withdrawing.
Is there a "too late" to start saving?
No. Even if your child is 15, saving $200 per month for three years gives you $7,200 plus growth—money that reduces borrowing. Start where you are. Something is always better than nothing.
