Should I save for college or retirement first?

TL;DR. Retirement first — your kids can borrow for college through federal student loans and scholarships, but there is no loan product for retirement. Capture your full employer 401(k) match before putting a single dollar into a 529 plan. The math is clear: a dollar invested in your 401(k) at 35 grows to roughly $7.60 by 65 at 7%, while a Parent PLUS loan at 8.05% over 10 years costs about $1.45 per dollar borrowed.

The borrowing asymmetry — why order matters

The core principle is simple: your children can borrow for college, but you cannot borrow for retirement. Federal student loans, scholarships, work-study, and income-share agreements all exist for education funding. No equivalent exists for a retiree who falls short. Social Security replaces only about 40% of pre-retirement income for the average worker, and that percentage declines for higher earners.

Here is a worked example with 2026 numbers. A 35-year-old parent earns $120,000 and has an employer 401(k) match of 50% on the first 6% of salary — worth $3,600 per year in free money. If this parent skips the match to fund a 529 plan instead, they forfeit $3,600 annually. Over 30 years at a 7% real return, that forfeited match alone grows to approximately $340,000 in lost retirement wealth. Meanwhile, the federal Direct Unsubsidized Loan rate for 2025-2026 is 6.53%, and Parent PLUS loans carry an 8.05% rate. Borrowing $40,000 in Parent PLUS loans over 10 years costs roughly $18,000 in total interest — painful, but far less than the $340,000 in lost compounding. The right order of operations: (1) capture the full 401(k) match, (2) pay off high-interest debt, (3) max out Roth IRA if eligible, (4) increase 401(k) contributions toward the annual limit ($23,500 in 2026, or $31,000 if age 50+), and (5) then fund the 529.

What a good college vs. retirement calculator should show

• Side-by-side projection of retirement wealth gained vs. student loan cost incurred.
• The dollar value of employer match contributions forfeited by under-funding a 401(k).
• Total interest cost of federal student loans and Parent PLUS loans at current rates.
• Impact of different savings splits (e.g., 70/30 retirement/college) on both goals.
• Tax advantages of 401(k) pre-tax contributions vs. 529 state tax deductions. AdvisorCal's College vs. Retirement Calculator models all of the above. Use it alongside the 401(k) Maximizer to optimize your contribution strategy, the Savings Growth Calculator to project compounding over different time horizons, or the Save Now vs. Later Calculator to see the cost of delaying retirement contributions by even a few years.

Key facts

• 2026 401(k) limit: $23,500 ($31,000 for ages 50+; $34,750 for ages 60-63 under SECURE 2.0).
• 2026 federal student loan rate (undergraduate): 6.53% for Direct Unsubsidized Loans.
• 2026 Parent PLUS loan rate: 8.05% with a 4.228% origination fee.
• Social Security replacement rate: approximately 40% of pre-retirement income for the average earner.
• 529 plan contribution: no federal deduction, but over 30 states offer a state income tax deduction or credit.
• Rule of thumb: every $1 of forfeited employer match costs $3-8 in lost retirement wealth over 25-30 years at 7%.

Common follow-ups

What if my employer does not offer a 401(k) match? The priority still favors retirement savings, but the gap narrows. Without a match, a Roth IRA ($7,000 limit in 2026, $8,000 if age 50+) offers tax-free growth and flexible withdrawal rules — Roth contributions (not earnings) can be withdrawn penalty-free at any time, giving you a partial emergency backstop. Fund the Roth IRA first, then split remaining savings between additional retirement contributions and the 529 based on your timeline and shortfall for each goal.

Can I use a Roth IRA for college expenses? You can withdraw Roth IRA contributions (not earnings) at any time without penalty or tax. Earnings withdrawn before age 59.5 for education expenses avoid the 10% penalty but are still taxed as ordinary income. This makes a Roth IRA a dual-purpose vehicle — prioritize it for retirement, but it provides a backstop for education if needed. However, Roth IRA distributions count as income on the following year's FAFSA, which can reduce financial aid eligibility.

How much does a 529 plan actually save in taxes? The federal benefit is tax-free growth — there is no federal deduction for contributions. State benefits vary: some states (e.g., New York, Illinois) offer deductions up to $10,000 per year, saving roughly $500-$800 in state taxes depending on your bracket. If your state offers no deduction, the 529's only advantage over a taxable brokerage account is tax-free growth on earnings — meaningful over 15+ years, but modest over shorter horizons.

Should grandparents fund the 529 instead? This is often the best structure. Under current FAFSA rules (effective 2024-2025), distributions from grandparent-owned 529 plans no longer count as student income, eliminating the old aid-reduction penalty. Grandparents also benefit from estate planning advantages — 529 contributions qualify for the annual gift tax exclusion ($19,000 per beneficiary in 2026), and a five-year front-loading election allows up to $95,000 in a single year without gift tax consequences.

When this doesn't apply

This priority order assumes you have not already reached a fully funded retirement trajectory. If you are on track to replace 80%+ of pre-retirement income and are maximizing tax-advantaged retirement accounts, funding a 529 plan is entirely appropriate and the tax-free growth is valuable. The advice also does not apply to parents whose children are within 2-3 years of college enrollment — at that point, the 529's investment horizon is too short for meaningful compounding, and a high-yield savings account or short-term bond fund may be more appropriate for education funds already earmarked.
