A $28,000 Degree Today Costs $290,439 for a Newborn
College costs have compounded faster than general inflation for decades. Running that forward eighteen years produces a number most parents have not seen, and it changes what a reasonable monthly contribution looks like.
The sticker price of a year at a public university sits around $28,000 once tuition, fees, housing, and food are included. For a child born today, that is not the relevant number. The relevant number is what the same year will cost in eighteen years, and college costs have historically risen faster than general inflation.
At 5% annual growth, that $28,000 year becomes $67,385. Four consecutive years, each more expensive than the last, total $290,439.
| Years from now | Cost of one year |
|---|---|
| Today | $28,000.00 |
| 5 years | $35,735.88 |
| 10 years | $45,609.05 |
| 18 years | $67,385.34 |
| Four-year total starting in 18 years | $290,439.23 |
What it takes to fund it
Saving the full $290,439 over eighteen years, in an account returning 6%, requires $749.80 a month. Of the eventual total, $161,958 comes from your contributions and $128,481 comes from growth. Compounding does roughly 44% of the work, which is the strongest argument for starting at birth rather than at any later point.
| Start at birth (18 years) | Start at age 8 (10 years) | |
|---|---|---|
| Monthly contribution required | $749.80 | $1,772.27 |
| Total contributed | $161,957.81 | $212,672.97 |
| Growth | $128,481.42 | $77,766.26 |
Waiting eight years raises the required monthly contribution by $1,022.47 and increases the amount you must contribute out of pocket by $50,715. The delay does not merely compress the schedule. It removes the years in which compounding would have done the most work, and you replace that growth with your own money.
A more realistic target
Funding four years entirely from savings is out of reach for most households, and treating it as the goal often produces paralysis rather than saving. A more useful framing is to decide what share you intend to cover.
- The one-third rule. Plan to cover roughly a third from past income (savings), a third from current income during the college years, and a third from student loans or the student's own earnings. On the figures above, that reduces the savings target to about $250 a month.
- Cover the in-state public option. Saving toward the cost of a state school leaves the family free to choose a more expensive institution if aid makes it viable, without having built the plan around it.
- Save what you can, consistently. A contribution of $200 a month from birth at 6% reaches roughly $77,000 by age eighteen, which is a meaningful reduction in borrowing even though it funds no complete degree.
The important point is that partial funding is not failure. Every dollar saved is a dollar not borrowed at student loan rates, and the difference between saving nothing and saving modestly is far larger than the difference between saving modestly and saving heroically.
Where to put the money
The account type matters more here than for most goals, because the tax treatment is unusually favourable and the time horizon is fixed and known.
| Vehicle | Main advantage | Main limitation |
|---|---|---|
| 529 plan | Tax-free growth and withdrawals for qualifying education costs; many states add a deduction or credit | Non-qualified withdrawals face tax plus a penalty on earnings |
| Coverdell ESA | Broader definition of qualifying expenses, including some K-12 costs | Low annual contribution limit and income restrictions |
| Custodial account (UTMA/UGMA) | No restriction on how funds are eventually used | Becomes the child's property at majority; weighed more heavily in aid calculations |
| Taxable brokerage account | Complete flexibility | No tax advantage; gains are taxed as realised |
For most families saving specifically for education, a 529 plan is the default. The tax-free growth is worth a great deal over an eighteen-year horizon, and recent rule changes have softened the main objection by allowing a limited amount of unused 529 funds to be rolled into a Roth IRA for the beneficiary, subject to conditions. Check your own state's plan first, since the state tax benefit often outweighs small differences in fund expenses.
Two things worth getting right
Shift the risk down as the date approaches. A portfolio appropriate for a newborn is inappropriate for a sixteen-year-old, because there is no time to recover from a decline before the first bill arrives. Most 529 plans offer age-based portfolios that do this automatically, which is a reasonable default for anyone who would not otherwise rebalance.
And do not fund college ahead of your own retirement. This ordering feels wrong to most parents and is nonetheless correct: your child can borrow for education at government-subsidised rates with income-driven repayment options, and you cannot borrow for retirement on any terms. A parent who arrives at retirement underfunded transfers a much larger problem to the same child a few decades later.

Is 5% the right assumption for college cost inflation?
It reflects the pattern of recent decades, during which published college costs rose faster than general inflation, though the gap has narrowed in recent years and net prices after aid have risen more slowly than sticker prices. Because the projection compounds over eighteen years, the assumption matters enormously: at 3% the four-year total falls to roughly $200,000 rather than $290,000. Running your own projection at both 3% and 5% is more informative than trusting either.
What happens to a 529 if my child does not go to college?
Several options avoid the penalty. The beneficiary can be changed to another family member, including siblings, cousins, or yourself. Funds can be used for many apprenticeship programmes and, within limits, for K-12 tuition and student loan repayment. Recent rules also permit rolling a limited lifetime amount into a Roth IRA for the beneficiary, subject to account age and contribution requirements. Only genuinely non-qualified withdrawals incur income tax plus a penalty, and that applies to earnings only, never to your contributions.
Does having savings reduce the financial aid we receive?
Somewhat, but far less than most families assume. Assets held by a parent are assessed at a much lower rate than assets held by the student in federal aid formulas, and retirement accounts are generally excluded from the calculation entirely. A parent-owned 529 is treated as a parental asset. The reduction in aid is typically a small fraction of the amount saved, so saving still leaves you meaningfully better off than not saving.
Should I save in a 529 or pay down my mortgage?
Compare the guaranteed return from the mortgage against the expected after-tax return in the 529. A 6.5% mortgage is a guaranteed 6.5%, which is competitive with an uncertain 6% growing tax-free. The 529 has the edge on tax treatment and the mortgage has the edge on certainty. What tilts it for most families is flexibility: mortgage equity cannot be accessed without borrowing against it, while 529 funds are available exactly when the tuition bills arrive.
How much do families actually pay compared with the sticker price?
Considerably less on average, particularly at private institutions, which typically discount heavily through institutional grants. Every accredited institution publishes a net price calculator showing estimated costs after aid for a family with your income and assets, and these are far more useful for planning than published rates. Run them for a few specific schools before setting a savings target.
