How Much Should I Save for College?
For a 5-year-old starting college at 18, the projected 4-year cost (at $35K/year today, 5% inflation) will be approximately $336,000. To fully fund this with $5,000 saved and $300/month contributions at 7% return, you’d accumulate about $148,000 — leaving a $188,000 shortfall. The recommended monthly contribution is roughly $675 to fully fund.

Why College Savings Math Is Harder Than It Looks
College costs have outpaced general inflation for decades. According to the College Board, the average published tuition at a four-year public in-state university is now around $11,400 per year, while private colleges average $43,000 per year — and that is tuition alone. Add room, board, fees, books, and transportation, and the all-in cost reaches roughly $27,000 per year for in-state public, $45,000 for out-of-state public, and $60,000+ for private institutions. College cost inflation has historically run around 5% per year, meaning today’s $35,000 sticker price will roughly double by the time a newborn starts freshman year.
This is why starting early matters. Compound growth is the parent’s best friend: a dollar saved at birth has 18 years to grow before college begins, while a dollar saved when your child is 14 has only 4. Even modest contributions of $200-$300 per month can grow to six figures if started at birth and invested in a diversified 529 age-based portfolio. The 529 plan is the most powerful vehicle for college savings because contributions grow federally tax-free and withdrawals for qualified education expenses are tax-free at both the federal and state levels. Many states also offer an up-front state income tax deduction for contributions — a hidden 8-9% immediate return in high-tax states like New York and Illinois. Use this calculator to project whether your current plan will hit the target, and adjust contributions as early as possible to close any funding gap.
529 Plan Strategies
Start at Birth
Opening a 529 at birth gives you 18 years of compound growth. $300/month from birth can grow to over $130,000 at 7% annualized — enough to cover several years of in-state public college.
Use Age-Based Portfolios
Most 529 plans offer age-based glide paths that automatically shift from equity-heavy when the child is young to bond-heavy as college approaches. This reduces the risk of a market crash right before freshman year.
Check Your State Deduction
Over 30 states offer a state income tax deduction or credit for 529 contributions. In high-tax states like New York, you can deduct up to $10,000 per couple per year — an instant 8-10% return. Contribute to your home-state plan first unless another plan has significantly lower fees.
Frequently Asked Questions
What if my child doesn’t go to college?
You have options: change the beneficiary to another family member (including yourself), use the funds for K-12 private tuition (up to $10,000/year), apprenticeship programs, or student loan repayments ($10,000 lifetime). Starting in 2024, unused 529 funds can also be rolled to a Roth IRA for the beneficiary up to $35,000 lifetime, subject to IRS rules.
How much can I contribute to a 529 plan?
There is no federal annual contribution limit, but contributions over the annual gift exclusion ($19,000 in 2026) may trigger gift tax reporting. A special 529 rule lets you “superfund” five years at once — contributing up to $95,000 per donor per beneficiary in a single year ($190,000 for couples) without gift tax.
Do 529 plans affect financial aid?
Yes, but only slightly. A parent-owned 529 is counted as a parent asset on the FAFSA, which reduces financial aid by only 5.64% of the account value at most. Grandparent-owned 529s used to hurt aid more, but as of 2024 they no longer reduce financial aid at all under the simplified FAFSA.
Should I use my home state’s 529 plan?
Generally yes, if your state offers a tax deduction. If your state has no income tax (or no 529 deduction), you can shop for the best plan nationally — look at low-cost plans like Utah’s my529, Nevada’s Vanguard 529, or New York’s 529 Direct Plan, all of which have expense ratios under 0.15%.
