College Savings (529) Calculator
Plan for your child's education with tax-advantaged savings
About the Calculator
College costs have risen faster than inflation for four consecutive decades, and the gap between what families save and what they actually need is the single biggest source of student debt. This calculator estimates your projected 529 balance at college enrollment, compares it against expected tuition costs (adjusted for education inflation), and shows you the surplus or shortfall in plain numbers. Change your monthly contribution or expected return to close the gap - or adjust the school type to see how choosing a public university over a private one affects the math. The earlier you start, the more compound growth does the heavy lifting. But even late starters can make a meaningful dent. The goal is to walk away knowing your number and your monthly target.

80-90% stocks, 10-20% bonds
Aggressive growth focus
5-10 Years Out
60-70% stocks, 30-40% bonds

What Is a 529 Plan?
A 529 is a tax-advantaged savings account specifically designed for education expenses. Named after Section 529 of the IRS tax code, these accounts let your money grow free of federal income tax, and withdrawals are tax-free as long as the money is used for qualified education expenses - tuition, fees, books, room and board, and more.
Unlike a standard investment account, you won't owe capital gains tax on the growth, which can amount to a significant difference over 18 years of compounding. Most states also offer an additional state income tax deduction or credit on contributions, making the effective return even higher in your first year of saving.
Every state sponsors at least one 529 plan, but you're not restricted to your home state's plan - you can open an account in any state and use the funds at eligible schools nationwide (and many abroad). Shopping around for the plan with the lowest fees and best investment options is worth doing before you open an account.
529 Plan Tax Advantages
- ✓Tax-Free Growth: Earnings grow federal tax-free and withdrawals for qualified education expenses are tax-free
- ✓State Tax Benefits: Many states offer tax deductions or credits for contributions
- ✓High Contribution Limits: Most states allow $300k-$500k+ total contributions per beneficiary
- ✓Gift Tax Strategy: Contribute up to 5 years worth ($90k in 2024) at once without gift tax
- ✓Roth IRA Rollover: New law allows up to $35k lifetime rollover to beneficiary's Roth IRA
The Formula
Examples
Example 1: Starting at birth
Parents open a 529 the month their child is born, deposit $5,000 as a starting balance, and contribute $300/month. At a 7% average annual return, by the time the child turns 18 they'd have accumulated approximately $126,000 - enough to cover a full four years at an in-state public university in most states, even accounting for tuition inflation. The key here is time: more than half of that balance is investment growth, not contributions.
Example 2: Starting at age 8 - the most common scenario
Many families don't think seriously about college savings until their child is in primary school. Starting at age 8 with $10,000 already saved and $300/month contributions gives roughly 10 years of growth. At 7% returns, the projected balance at age 18 is around $72,000 - a meaningful contribution toward a public university, but likely insufficient for private school costs without additional aid or loans. Bumping contributions to $500/month closes most of that gap.
Example 3: Late start at age 14 - aggressive catch-up
With only 4 years until college, a family with $40,000 saved and the ability to contribute $800/month can project roughly $88,000 by enrollment. At this stage, the investment allocation should already be shifting conservative (more bonds, less stocks) to protect what's been saved from a market downturn in the final years. The 529 covers a significant portion of costs, but loans or aid will likely fill the remainder.
FAQ
What happens if my child doesn't go to college?
You have several options. You can transfer the account to another family member - a sibling, cousin, or even yourself - without penalty. Since 2024, you can also roll up to $35,000 of unused funds into a Roth IRA for the beneficiary (subject to annual contribution limits). If you withdraw funds for non-qualified expenses, you'll owe income tax plus a 10% penalty on the earnings portion only - not the contributions.
Can I use a 529 for K-12 expenses?
Yes, up to $10,000 per year per child can be used for K-12 private school tuition. This is a federal rule, but some states don't conform to it - meaning your state might still tax those withdrawals. Check your specific state plan before using 529 funds for K-12 costs.
Does a 529 affect financial aid eligibility?
A parent-owned 529 is counted as a parental asset on the FAFSA, which has a relatively low impact on aid eligibility - reducing aid by at most 5.64% of the account value. Student-owned accounts are assessed at a higher rate (20%). Grandparent-owned 529s used to cause larger aid reductions, but FAFSA rule changes effective from 2024 have largely eliminated that problem.
Can I use a 529 at any school?
Most accredited colleges and universities in the US qualify, including community colleges and many trade schools. Many international universities are also eligible. Use the Department of Education's Federal School Code lookup to check if a specific institution qualifies.
What's the best investment strategy inside a 529?
Most 529 plans offer age-based portfolios that automatically shift from growth-oriented (stocks) to conservative (bonds and cash) as college approaches - a sensible default for most families. If you're managing allocations manually, the glide path shown above (80–90% stocks when 10+ years out, shifting to 30–40% stocks in the final 5 years) is a widely-used rule of thumb.
How much should I be saving each month?
A common target is to aim for savings that cover roughly one-third of projected costs, with financial aid and out-of-pocket payments from income covering the rest. For a public university, that might mean $200–$300/month from birth. For private university coverage, $500–$700/month. Use this calculator to find your specific target based on your child's age and current balance.
Tips & Strategies
Your home state's plan may not be the best one. Compare expense ratios across state plans. a 0.5% difference in annual fees compounds significantly over 18 years.
The federal annual gift tax exclusion is $18,000 per person per year (2024). Grandparents can each contribute $18,000 without triggering gift tax. a useful way to accelerate the balance early.
Superfunding. contributing 5 years of gifts upfront ($90,000 per donor in 2024) - is a powerful option for grandparents or other relatives who want to make a large, lump-sum contribution while removing assets from their taxable estate.
529 funds can now be used for K-12 private school tuition up to $10,000/year per child, not just college. a relatively recent expansion worth knowing about if private schooling is in the picture.
Unused 529 balances can now be rolled over into a Roth IRA for the beneficiary (up to $35,000 lifetime, subject to annual Roth contribution limits), as of 2024. This significantly reduces the penalty risk of oversaving.
Things Worth Knowing
- •Tuition has outrun almost everything. College costs have risen roughly 1,200% since 1980, compared to around 270% for general consumer prices. A degree that cost $10,000 in 1980 would cost over $120,000 today at the same institution.
- •Time is worth more than money here. Saving $200/month from birth yields roughly $95,000 by age 18 at 7% returns. Starting the same savings at age 10 yields only around $33,000 - less than a third, from the same monthly investment.
- •The average graduate debt load. College graduates in 2026 carry an average of around $37,000 in student loan debt. At a standard 10-year repayment on a federal loan, that's roughly $370/month - comparable to a car payment, running for a decade.
- •529s aren't just for four-year universities. Funds can be used at accredited community colleges, trade schools, vocational programs, and many international universities - making them useful even if traditional college isn't the path.
