College Savings Calculator

College costs in the US have outpaced inflation for decades. The average four-year private college now costs over $200,000 with room and board, while public universities run $100,000–$120,000 for in-state students. Planning early — and using tax-advantaged accounts — is the difference between graduating debt-free and starting careers with six-figure loans.

This calculator projects your current savings forward at your assumed return rate, adds your monthly contributions, and compares the total to your child's expected four-year cost (net of scholarships). The "funding gap" is what's left to cover; the "monthly to fully fund" is the total monthly contribution that closes the gap by the time college starts.

The most effective vehicle for college savings in the US is a 529 plan: tax-free growth and tax-free withdrawals when used for qualified education expenses. Most states also offer state income tax deductions for contributions. Start as early as possible — even $100/month from birth can grow to $40,000+ by age 18 at typical market returns.

Don't over-fund a 529 if you're not sure your child will attend college — withdrawals for non-education purposes incur taxes plus a 10% penalty on earnings (recent SECURE 2.0 legislation does allow some 529 funds to roll into Roth IRAs). Balance education savings against retirement: you can borrow for college, but you can't borrow for retirement.

529 plans are the most powerful college-savings vehicle in the US tax code. Contributions grow tax-free, withdrawals for qualified education expenses are tax-free, and many states offer a state-income-tax deduction on contributions. The plan stays in the parent's name (preserving control) and counts only modestly against financial-aid calculations. Every state offers at least one 529, and you are not required to use your own state's plan — shop for the lowest fees and best investment options.

Starting early is the single biggest lever. $200/month saved from a child's birth grows to roughly $77,000 by age 18 at a 6% return, but only $42,000 if you wait until age 8 to start. Time in the market matters more than the amount contributed in any single year. If you cannot start with $200, start with $50 — the habit and the compounding curve matter more than the initial amount.

College costs have outpaced general inflation for four decades. Sticker prices at private four-year colleges average $60,000+ per year all-in; flagship public universities run $25,000–$35,000 for in-state students. Net prices (after grants and scholarships) are much lower — many families pay 40–60% of sticker. Use the published net-price calculator on each college's website to get a realistic estimate of what you would actually pay.

Scholarships, grants, work-study and in-state tuition are the four big ways to reduce out-of-pocket cost. Merit scholarships from individual schools dwarf almost every external scholarship database in dollar terms — focus your application energy on schools where your student profile lands in the top 25% of admitted applicants. Free tools like the College Board's BigFuture and Niche let you filter schools by historical merit-aid generosity.
