Saving for College: Why the Bill Is Double What You Think
Four years at $25,000 each is $100,000 in today's money. By the time a newborn gets there it is $224,011. Rising costs add $124,011 - more than the original bill. Starting fifteen years out means $781 a month. Starting five years out means far more, which is why the number matters more than the strategy.
The number that doubles while you are not looking
Four years of education at $25,000 a year is $100,000. That is the figure most people carry around.
It is also the figure for someone starting today. If your child is a newborn, the bill lands eighteen years from now, and each of those four years costs more than the last.
At 5% cost rises, from the college savings calculator:
| Year of study | Years from now | Costs |
|---|---|---|
| First | 15 | $51,973 |
| Second | 16 | $54,572 |
| Third | 17 | $57,300 |
| Fourth | 18 | $60,165 |
| All four | $224,011 |
| Amount | |
|---|---|
| Cost in today's money | $100,000 |
| What rising costs add | $124,011 |
| Total needed | $224,011 |
Rising costs add more than the original bill. That is the single most important thing on this page, and it is why planning around today’s sticker price leaves people badly short.
What it takes each month
To reach $224,011 in fifteen years at a 6% return: $781 a month.
That is a real number and for many households it is a difficult one. Which is exactly why it is worth knowing early rather than discovering at fourteen.
Starting later costs more than the missed contributions, because you also lose the years of compounding those contributions would have had. Every year of delay makes the monthly figure jump more than the previous year did.
The order that matters more than the amount
Here is the part that gets emotional, and it is worth being direct about.
Fund your own retirement first.
There are loans for education. There are none for retirement. A parent who arrives at 70 with nothing put aside becomes a cost their children have to carry - and that cost typically dwarfs a tuition bill.
Paying for education instead of your own retirement does not spare your children an expense. It moves the expense later, makes it larger, and gives them no way to borrow for it.
So the sensible order is:
- Emergency fund
- Any employer retirement match - that is free money, see the 401(k) guide
- Expensive debt
- Retirement saving
- Then education saving
That is not selfishness. It is arithmetic.
What to do with a number you cannot reach
Most people cannot save $781 a month. That does not make the exercise pointless.
Save what you can. $300 a month for fifteen years is a substantial contribution even if it is not the whole bill. Partial funding means less borrowing, which means less interest.
Do not treat the number as all-or-nothing. Education is rarely paid entirely from savings. It is usually savings plus current income plus some borrowing plus whatever the institution offers.
Revisit it. Costs and plans both change. A figure worked out today is a starting point, not a commitment.
Be honest about the type of education. $25,000 a year is one kind of assumption. A different route can cost a fraction of that, and the difference is enormous when compounded over eighteen years.
The account, briefly
For money genuinely earmarked for education, a 529 is usually the right home. Growth and qualified withdrawals avoid tax, and many states add a deduction on top.
The trade is flexibility. Take money out for something else and the growth faces tax and a penalty.
A sensible approach is to put the amount you are confident about into a 529 and keep anything doubtful somewhere more flexible. That way you get the tax treatment on the certain part without locking up money whose purpose might change.
Where to start
- Work out your real number, with cost rises included, not today’s prices.
- Check your retirement saving is on track first.
- Start something, even if it is small. The years matter more than the amount.
- Revisit every few years.
Run your own figures in the college savings calculator - it shows each year of study at its future cost, what rising prices add, and the monthly amount needed to get there.
Common questions about college savings
How much do I need to save for college?
Far more than today's prices suggest. Four years at $25,000 each is $100,000 now. Fifteen years from now with costs rising 5% a year it comes to $224,011 - because each year of study costs more than the one before it, and the last year is eighteen years away.
Why is the total more than double?
Because education costs have historically risen faster than general prices, and the bill lands years in the future. At 5% a year over fifteen years, the first year of study costs $51,973 rather than $25,000 - and the fourth year costs $60,165.
How much do I need to put away each month?
On those figures, $781 a month for fifteen years at a 6% return. Starting later means considerably more, because you lose both the contributions and the years of compounding on them.
Should I save for this before my own retirement?
Generally no, and it is worth being blunt about. There are loans for education and none for retirement. Filling a retirement account first is not selfish - it stops your children supporting you later, which costs them far more than tuition.
Is a 529 the right account?
For money genuinely earmarked for education, usually yes - growth and qualified withdrawals avoid tax, and many states add their own deduction. The trade is flexibility: non-qualified withdrawals face tax and a penalty on the growth. Save what you are confident about there and keep the rest elsewhere.
