The Tuition Inflation Problem
College tuition historically increases at 5–7% per year — significantly faster than general inflation (~3%). The future cost of tuition starting at today:
where is the annual tuition inflation rate and is years until enrollment.
| Current annual cost | In 10 years (5%) | In 18 years (5%) |
|---|---|---|
| $10,000 (in-state public) | $16,289 | $24,066 |
| $25,000 (out-of-state) | $40,722 | $60,166 |
| $55,000 (private) | $89,590 | $132,365 |
Monthly Savings Needed
To accumulate a target amount in years with monthly contributions earning rate :
This is the sinking fund formula — solving the annuity future value for the payment amount. For example, to save $100,000 in 18 years at 6% return:

Tax advantage
Contributions grow tax-free, and withdrawals for qualified education expenses (tuition, room, board, books) are tax-free at the federal level.
Effective return boost
Tax-free growth effectively increases your return. A 6% return in a taxable account (25% tax rate) yields ~4.5% after tax. In a 529, you keep the full 6%.
The Savings Gap
The difference between your projected savings and the projected cost:
The factor of 4 accounts for four years of tuition. A positive gap means you'll need loans, scholarships, or increased contributions to close the shortfall.
Frequently Asked Questions
How much should I save each month for college?
It depends on the target cost and time horizon. Using the sinking fund formula, saving for $100,000 over 18 years at a 6% return requires roughly $258 per month. Starting when a child is born gives you the longest compounding window; waiting until age 8 roughly doubles the required monthly amount.
What is a 529 education savings plan?
A 529 plan is a tax-advantaged investment account designed for education expenses. Contributions grow tax-free at the federal level, and withdrawals for qualified expenses (tuition, room, board, books) are also tax-free. Many states offer additional income tax deductions for contributions.
How fast does college tuition increase?
College tuition has historically risen at 5--7% per year, significantly faster than general inflation (~3%). At 5% annual growth, a $10,000 annual tuition today becomes roughly $24,000 in 18 years. This means savings must grow faster than inflation to keep pace.
What is the savings gap and how do I close it?
The savings gap is the difference between your projected savings at enrollment and the projected four-year tuition cost. A positive gap means a shortfall. You can close it by increasing monthly contributions, starting earlier, seeking higher returns, or planning for scholarships, grants, and financial aid.
Does the tax advantage of a 529 plan really make a big difference?
Yes. A 6% return in a taxable account (at a 25% marginal rate) nets roughly 4.5% after taxes. In a 529, you keep the full 6%. Over 18 years, that 1.5% difference can add 15--20% more to your final balance compared to a taxable account.
