There is no single right amount — it depends on what you want to cover and when your child starts college
The monthly savings target that works for your family depends on three things: how many years until college, what portion of costs you want to cover, and which schools you're thinking about. A parent with a newborn and 18 years ahead can save less per month than a parent with a 10-year-old. Someone aiming to cover half the cost needs a different plan than someone aiming to cover all of it. And the costs at a public university in your state are different from a private school across the country.
Rather than chasing a number you read somewhere, you can work backward from what you actually want to achieve. This section shows you how to set a realistic target based on your own situation.
Key Takeaways
- College costs vary widely — in-state public universities average less than half the cost of private schools, and costs change year to year.
- You can calculate a monthly savings target by deciding how much you want to cover, subtracting what you expect from other sources (grants, scholarships, student work), and dividing by the months remaining.
- Starting early matters because your money has more time to grow through interest and investment returns, which reduces how much you need to save from your own pocket each month.
- A 529 college savings plan lets your savings grow tax-free, which means you reach your target faster than saving in a regular bank account.
- If you cannot save the full amount, any regular savings is better than none — even modest monthly deposits add up over years.
What college actually costs right now
College costs vary by school type and location. For the 2023–2024 school year, published costs (tuition, fees, room, and board) averaged roughly $28,000 per year at public universities for in-state students, $46,000 at private colleges, and $16,000 at community colleges. These are averages — your state's schools may cost more or less, and costs rise each year.
The number that matters for your planning is not the average but the actual cost at schools your child might attend. If you have specific schools in mind, you can find their current cost on their website under "cost of attendance" or "net price calculator." If you are planning broadly, using $25,000 to $30,000 per year for a public in-state school is a reasonable starting point, but check your own state's schools to be sure.
Multiply the annual cost by four to get a rough total for a four-year degree. A public in-state school at $28,000 per year would be about $112,000 total. That is the number you will use to work backward to a monthly savings target.
How to calculate what you need to save each month
Start with the total cost you want to cover. Let's say you want to cover $100,000 of a four-year degree. Next, subtract what you expect to come from other sources: scholarships, grants, your child's part-time work, or student loans you are willing to take. If you expect $20,000 from scholarships and $10,000 from your child working during school, you need to save $70,000 yourself.
Now count the months until your child starts college. If your child is 8 years old and will start at 18, you have 120 months. Divide $70,000 by 120 months and you get roughly $583 per month. That is your target before any growth from interest or investment returns.
In reality, your money will grow as it sits in a savings account or investment account, so you will not need to save the full $583 every month. A 529 plan or high-yield savings account will reduce that number. But $583 is a useful starting point to know whether the goal feels realistic for your budget.
| Years until college | Monthly savings needed (before growth) to reach $70,000 |
|---|---|
| 18 years (newborn) | $325 |
| 14 years (age 4) | $417 |
| 10 years (age 8) | $583 |
| 6 years (age 12) | $972 |
| 2 years (age 16) | $2,917 |
This table shows the monthly amount needed to save $70,000 with no investment growth. The earlier you start, the smaller the monthly payment. If you start when your child is a newborn, you save less than half per month compared to waiting until age 12.
Why starting early makes a real difference
The reason early savers need smaller monthly amounts is that their money has time to earn returns. In a high-yield savings account earning 4% to 5% annually, $325 per month over 18 years grows to roughly $80,000 — your $58,500 in deposits plus $21,500 in interest. In a 529 plan invested in stock-based funds, the growth is typically larger, but also varies with market performance.
A parent starting when their child is 12 years old does not have that luxury. Saving $972 per month for 6 years in a high-yield account earning 4% annually grows to about $60,000 — your $58,320 in deposits plus only $1,680 in interest. The shorter timeline means less of your target comes from growth and more must come from your own pocket.
This is not an argument that you have failed if your child is already 10 or 12. It is an argument for starting now with whatever amount you can manage, rather than waiting for a "perfect" plan. Even $200 per month for 6 years is $12,000 plus interest — real money that reduces what your child needs to borrow or earn.
How a 529 plan changes the math
A 529 college savings plan is a tax-advantaged account offered by each state. Money you deposit grows tax-free, and withdrawals for college expenses are not taxed. This means your money grows faster than it would in a regular savings account, so you reach your target with smaller monthly deposits.
The difference is meaningful but not magical. If you save $400 per month for 15 years in a regular savings account earning 0.5% (typical for basic accounts), you end up with about $72,000. In a 529 plan earning 6% annually through a mix of stocks and bonds, the same $400 per month grows to roughly $110,000. The 529 gets you there faster, but you still need to actually save the money — the account does not create it.
Each state runs its own 529 plan, and you can use any state's plan regardless of where you live. You choose how the money is invested — conservative options that stay mostly in bonds, moderate options that mix stocks and bonds, or aggressive options that are mostly stocks. The more aggressive the investment, the higher the potential growth, but also the higher the risk if the market drops right before college starts.
What to do if you cannot save the full target amount
Many families cannot save $500 or $1,000 per month. If your budget allows $200 per month, that is still $2,400 per year, or $24,000 over 10 years before any growth. That is real money that reduces what your child needs to borrow.
You have other options beyond your own savings. Your child can work part-time during high school and college. They can attend a community college for the first two years (roughly half the cost of a four-year university) and transfer. They can take out federal student loans, which have fixed interest rates and income-based repayment options. They can look for scholarships and grants based on academic performance, athletic ability, or financial need.
The goal is not to save every dollar yourself. The goal is to save what you reasonably can, so your child's total cost is split among your savings, their work, scholarships, and loans — rather than loans alone.
Frequently Asked Questions
Should I save for college or pay off debt first?
If you have high-interest debt like credit cards, paying that down usually makes more sense than college savings. High-interest debt costs you more than college savings can earn. If your debt is low-interest (like a mortgage) or you have no debt, you can do both — even small college savings is better than waiting until debt is gone.
What if my child gets a scholarship?
Money you saved can be used for expenses scholarships do not cover — room and board, books, computers, or living costs. If a full scholarship covers everything, you can redirect that monthly savings to other goals. Some 529 plans allow you to transfer unused funds to a sibling's account.
Can I save too much in a 529 plan?
Yes, but the limit is high — roughly $235,000 per child depending on your state. If you save more than your child uses for college, unused funds can be withdrawn (you pay taxes and a penalty on the earnings) or transferred to a family member's account. Most families will not hit this limit.
Does saving for college hurt my child's chances of financial aid?
Parent-owned 529 plans have minimal impact on federal financial aid calculations. Student-owned accounts and savings in the student's name reduce aid may be able to access more. If you think your family will may have access to for need-based aid, a parent-owned 529 is a better choice than a student savings account.
What if I start saving when my child is already a teenager?
You can still save something. Even $300 per month for 4 years is $14,400 plus interest. Your child can cover the rest through scholarships, work, and loans. Starting late is not ideal, but starting is better than not saving at all.
