How Much Does College Actually Cost?
The sticker price of college is higher than most families realize, and it keeps rising. According to the College Board's Trends in College Pricing, average published tuition and fees for the 2024-2025 academic year are:
| School Type | Average Annual Tuition and Fees | Average Total Cost (with room and board) |
|---|---|---|
| Public four-year, in-state | $11,610 | $28,840 |
| Public four-year, out-of-state | $30,780 | $46,730 |
| Private four-year | $43,350 | $60,420 |
These are averages. Elite private universities can exceed $80,000 per year including room and board. Many public universities offer a solid education for under $25,000 per year for in-state students. The college savings target you enter in the calculator should reflect the type of school you are planning for.
College costs have increased at roughly 4-6% per year on average over the past two decades, significantly faster than general inflation. If your child is 5 years old today, by the time they start college in 13 years, those costs will be 65-100% higher than current prices based on historical trends. The calculator accounts for tuition inflation so your target reflects what you will actually owe, not what college costs today.
What Is a 529 Plan and Why It Matters
A 529 plan is a tax-advantaged savings account designed specifically for education expenses. The name comes from Section 529 of the IRS tax code. Every state offers at least one 529 plan, and you are not required to use your home state's plan.
Tax advantages:
What counts as a qualified expense: Tuition, room and board, required fees, books, supplies, computer equipment, and, as of 2018, up to $10,000 per year for K-12 private school tuition.
What if my child does not go to college: You can change the beneficiary to another family member with no penalty. As of 2024, up to $35,000 in unused 529 funds can be rolled into a Roth IRA for the beneficiary over their lifetime, eliminating the previous "trapped money" concern for overfunded accounts.
Non-qualified withdrawals: If you withdraw money for non-qualified expenses, you pay income tax plus a 10% penalty on the earnings portion only. Your original contributions are always available penalty-free since they were made with after-tax dollars.
How Much Should You Save Monthly?
The answer depends on four variables: the current age of your child, the type of college you are planning for, how much you have saved already, and your assumed investment return.
| Child's Current Age | Years Until College | Monthly Savings Needed (Public In-State) | Monthly Savings Needed (Private University) |
|---|---|---|---|
| Newborn | 18 years | ~$350/month | ~$850/month |
| 3 years old | 15 years | ~$450/month | ~$1,100/month |
| 5 years old | 13 years | ~$550/month | ~$1,350/month |
| 8 years old | 10 years | ~$750/month | ~$1,850/month |
| 10 years old | 8 years | ~$1,050/month | ~$2,600/month |
| 12 years old | 6 years | ~$1,600/month | ~$3,900/month |
These estimates assume 6% investment growth and 5% annual tuition inflation, and a goal of covering 100% of costs. Most families do not aim to cover 100% of college costs from savings alone, and that is fine. Financial aid, merit scholarships, student loans, and student income typically cover a portion. The calculator lets you set your coverage target.
The 529 Plan Contribution Strategy
Start early. The math advantage of starting at birth versus starting at age 10 is enormous. Starting at birth with $300/month gives you roughly the same result as starting at 10 with $1,050/month. Earlier and smaller beats later and larger.
Use your state's deduction if available. Check whether your state offers a tax deduction for 529 contributions. In states like New York (deductions up to $10,000/year) or Virginia (deductions up to $4,000/account/year), this is a meaningful benefit. Even if your state does not offer a deduction, a 529 still beats a taxable account due to federal tax-free growth.
Avoid picking individual stocks. Most 529 plans offer age-based investment options that automatically shift from growth-oriented assets (stocks) when the child is young to conservative assets (bonds and cash) as college approaches. These are sensible defaults for most families. The risk of a large stock market decline the year before college starts is real, and age-based funds manage that risk automatically.
Do not over-contribute. While excess funds can now roll into a Roth IRA, there are limits and waiting periods. Aim to fund the account based on realistic projections rather than massively over-funding.
What About Financial Aid?
A 529 plan is counted as a parental asset on the FAFSA (Free Application for Federal Student Aid). Parental assets reduce financial aid eligibility by a maximum of 5.64% per year. That means a $100,000 529 balance reduces your expected aid by at most $5,640. This impact is modest and does not change the calculation significantly for most families.
Grandparent-owned 529 plans were previously treated differently on the FAFSA, but as of the 2024-2025 FAFSA cycle, distributions from grandparent-owned 529 plans no longer count as student income, eliminating the previous disadvantage of grandparent-held accounts.
If you are concerned about financial aid impact, saving in a 529 held in a parent's name is the most favorable treatment available. Custodial accounts (UGMA/UTMA) are treated as student assets, which have a higher impact on financial aid calculations.
Alternative College Savings Approaches
Roth IRA for college: Contributions to a Roth IRA (not earnings) can be withdrawn penalty-free at any time for any purpose. Some families use a Roth IRA as a college savings vehicle because it offers more flexibility: if your child receives a full scholarship or decides not to go to college, the money stays available for retirement. The downside is that Roth IRA contributions also reduce your retirement savings, and the annual contribution limit ($7,000 in 2025) is lower than 529 contribution limits.
I Bonds: U.S. Treasury I Bonds earn interest at a rate tied to inflation and are exempt from federal taxes when used for education expenses. They have annual purchase limits ($10,000 per person) and a one-year minimum holding period. They are a reasonable supplement for part of a college fund but not a standalone strategy.
529 vs. paying off the mortgage first: Some financial advisors argue that parents should prioritize their own retirement and mortgage payoff before funding college accounts. The logic is sound: you cannot borrow for retirement, but students can borrow for education. A reasonable approach is to balance all three rather than neglecting any one entirely.
When Starting Late: Realistic Options
If your child is 10 or older and you have not started saving, there are still meaningful options:
Save aggressively for a shorter period. Even $500-$800 per month for 6-8 years builds a significant fund. It may not cover all costs, but it meaningfully reduces borrowing.
Target lower-cost schools. Public in-state universities deliver excellent educations at a fraction of the cost of private schools. Community college for the first two years, then transferring to a four-year school, can cut total tuition by 40-50%.
Apply aggressively for merit scholarships. Academic, athletic, and need-based scholarships can cover substantial portions of cost. Families with incomes under $75,000 often qualify for significant institutional aid at private schools.
Federal student loans are not catastrophic at reasonable levels. Graduating with $20,000-$30,000 in federal student loans is manageable. Graduating with $80,000-$120,000 in private loans is a different situation. Understanding the difference matters.
Real-World Examples
Example: Marcus and Ellen, parents of a 2-year-old
Situation: They want to save for a public in-state university, estimated to cost $160,000 by the time their daughter turns 18. They have $3,000 saved.
What they calculated: With 16 years, $3,000 already saved, and a 6% investment return, they need to save approximately $420 per month to hit their target.
Result: They open a 529 at their state's plan to capture the state tax deduction, invest in an age-based growth fund, and automate $425/month. On track without disrupting other financial goals.
Example: Dana, parent of a 12-year-old, starting late
Situation: Dana has $8,000 in a savings account she originally intended for college. Her daughter is six years from starting school.
What she calculated: A modest public university will cost approximately $90,000. With $8,000 saved and 6 years to grow, she needs $1,100/month to cover costs fully. That is out of reach.
Result: Dana moves the $8,000 into a 529, contributes $500/month, and plans to cover the remaining gap with a combination of merit aid, federal student loans, and her daughter working part-time. She focuses remaining savings on her own retirement, which has a higher cost of not being funded.
