Renee and Paul did almost everything right for twenty-five years. Steady careers. A paid-off first mortgage. A healthy, growing retirement account. Then their oldest got into a good college, one that cost more every month than their old mortgage payment ever did.
They co-signed the loan. Of course they did. Then their second child needed the same. Two co-signed loans, roughly $80,000 combined. To make the payments feel manageable, they slowed their own retirement contributions (just for a few years, they told themselves).
A few years became a decade. At 61, they discovered their retirement savings hadn’t meaningfully grown in ten years, while their oldest, now facing his own financial strain, had fallen behind on the loan they co-signed. Their credit took the hit. Their retirement date moved a decade later than planned.
Co-Signing Doesn’t Feel Like Debt. It Is Debt.
Here’s the trap that catches even careful, loving parents: co-signing a student loan doesn’t feel like taking on debt. It feels like an act of love. But legally and mathematically, it’s identical to borrowing the money yourself. If your child can’t make a payment, you’re on the hook for the balance, the credit damage, and the stress at precisely the stage of life when you have the least time left to recover.
This isn’t a caution against helping your kids. It’s a caution against exposure without a plan.
The Real Problem: Sequential Thinking Applied to a Simultaneous Decision
Once a family reaches Stage 4, debt-free except the mortgage, building real wealth, retirement, college funding, and mortgage acceleration stop being a checklist you complete one at a time. They become three goals running simultaneously, competing for the same monthly dollar.
Treat them sequentially, ‘college first, retirement later’, and the math never catches up. There’s no getting back a decade of lost compound growth. Time is the one input retirement math can’t recover once it’s spent.
The Three-Goal Formula
This week’s insight article, a real coaching session covering Baby Steps 4, 5, and 6, walks through exactly this balancing act. A couple with $904,000 already saved for retirement had to decide how to split every surplus dollar between retirement, their son’s prepaid college program, and their mortgage.
The math mattered. Their son’s prepaid tuition program charged zero interest, so accelerating those payments had no financial upside. Their mortgage carried a 3% rate, a guaranteed return if paid down faster. Their retirement accounts, split between traditional and Roth, offered long-term growth and tax diversification.
The formula that emerged: retirement contributions come first, non-negotiably, at a minimum of 15% of income. Surplus dollars beyond that go wherever the return is highest, often mortgage acceleration ahead of a zero-interest college obligation. College itself gets funded through vehicles built for that purpose, 529 plans, scholarships, the student’s own summer earnings, not by pausing retirement or co-signing a loan that puts your entire financial future at risk.
What Renee and Paul Would Do Differently
If Renee and Paul had followed this formula a decade earlier, retirement contributions would have stayed at 15% the whole time, no pause, no exceptions. College costs would have been split between an early-started 529 plan, their children’s own contributions, and an honest conversation about in-state tuition versus the most expensive option available. Co-signing would have been a last resort, not the default plan.
It is the same cost conversation we walk through with families weighing $56,000-a-year private school tuition. Naming the real number early is what keeps it from becoming a decision made under pressure, in the moment, by parents who love their kids.
None of that requires loving your kids any less. It requires refusing to let ‘college first’ quietly turn into ‘retirement never.’
Your Move This Week
Pull your current retirement contribution rate and your current college savings or loan payments side by side. If retirement has dropped below 15% to make room for college costs, that’s the fix this week needs, not the tuition bill.
