Why the economy leaves some people behind — and how one little-known rule about retirement savings can change everything for people on public assistance.
Not financial or benefits advice. The information on this page is educational only. Every household's benefits situation is different. Before making any changes, please talk to your county social worker or a benefits counselor to understand how retirement contributions apply to your specific case. Benefit rules and income thresholds change annually — always confirm with official California program sources.
Part 1
You've probably heard that the economy is doing well. Stock markets hit new highs. Unemployment is low. Wages are up. But those headline numbers hide a more complicated truth: the gains are not shared equally. Economists call it the K-shaped recovery.
Imagine the letter K. The upper branch curves upward — that's the top half of earners, building wealth through home ownership, stock portfolios, and retirement accounts. The lower branch curves downward — that's the bottom half, falling further behind despite working just as hard.
The question isn't whether you're working hard. It's whether the system is set up to let you build wealth. And for people on public assistance, there's a specific, concrete barrier standing in the way — one that most people have never heard of.
Before we go further, it's worth saying plainly: if you're reading this while trying to figure out how to stretch this week's groceries, retirement is probably not what's on your mind, and it shouldn't be. That struggle is real, and nothing here is meant to suggest you should be thinking about a retirement account when you're focused on getting through the week. But the strategy in this article isn't really about retirement first — it's about keeping the Medi-Cal you already have, today, as your income changes. Building wealth for the future happens to be a side effect of that same move. If a small contribution can be the difference between losing your benefits and keeping them, it's worth knowing about — even if "saving for retirement" isn't the frame that makes it feel relevant to your life right now.
"The difference between the two branches of the K isn't talent or effort. It's access to wealth-building tools — and one rule that blocks millions of people from using them."
Part 2
California's health assistance programs — Medi-Cal and Covered California — are designed to help families access healthcare. They do. But they're built around income thresholds: earn below a certain amount and you qualify; earn above it and you don't.
The problem is that these cutoffs are cliffs, not slopes. There's no gradual phase-out. One dollar over the limit and you can lose thousands of dollars in benefits — instantly.
A single parent with two kids earns $2,100/month and qualifies for Medi-Cal with free coverage (value roughly $600/month). Their employer offers a raise to $2,500/month.
That $400 raise pushes them over the Medi-Cal income limit. They lose the coverage entirely. Net result: they now earn $400 more but lose healthcare worth $600/month — a net loss of $200 every single month.
This is the cliff. And it's not a glitch. It's how the system is designed.
People on assistance aren't unaware of this. They live it. Many deliberately avoid raises, turn down extra hours, or stay in lower-paying jobs because they've done the math and know that earning more will leave them worse off. Economists call this a poverty trap — a structural feature of the system that punishes the very behavior it's supposed to reward.
The cliff doesn't just hurt families in the short term. It prevents them from ever building the kind of economic foundation — savings, investments, retirement security — that would make them permanently self-sufficient. It keeps the lower branch of the K going down.
Net resources = (Income + Benefits) − (Taxes + Expenses) — family of 3
As income rises, net resources climb steadily — until a benefits threshold is crossed and a cliff causes a sudden drop, even though wages went up. Contributing to a Traditional IRA or 401(k) right at that threshold can hold income just under the line, creating a plateau instead of a drop — buying time for wages to climb high enough to clear the threshold for good.
How long that plateau can last depends on how much room a retirement account gives you. A Traditional IRA shelters up to $7,500 a year in 2026 — a realistic number for most working families navigating this, and the figure this site is built around. If you have access to a 401(k) through an employer, the technical ceiling is much higher — up to $24,500 a year — though reaching that limit while staying near a benefits threshold is a narrow scenario that applies to relatively few households. The realistic takeaway either way is the same: even a modest contribution can hold the line flat for a while, buying time for wages to keep climbing underneath it.
Part 3
Here's the part most people don't know. California's benefits programs don't look at your paycheck. They look at something called your MAGI — Modified Adjusted Gross Income. And MAGI is not the same as what you earn.
MAGI is your income after certain deductions. One of the biggest deductions available to almost any working person is a contribution to a pre-tax retirement account — a Traditional IRA, a 401(k), a SEP-IRA, or a SIMPLE IRA.
When you put money into one of these accounts, that money doesn't count as income for the purposes of benefits eligibility. Your gross pay stays the same. But your MAGI — the number the programs actually use — goes down.
You earn $34,000 a year. The Medi-Cal limit for your household is $32,000. You're over the cliff — no coverage.
But if you contribute $2,400/year ($200/month) to a Traditional IRA, your MAGI drops to $31,600. You're now under the threshold. Medi-Cal coverage: restored.
You kept your raise. You kept your benefits. And you now have $2,400 growing in a retirement account.
This isn't a loophole. It isn't tax fraud. It's how the system is designed to work — Congress intentionally excluded retirement contributions from MAGI specifically to encourage savings. The problem is that nobody tells people on assistance that this tool exists and applies to them too.
Part 4
The annual contribution limit for a Traditional IRA in 2026 is $7,500. That means you can shelter up to $7,500 of your income from MAGI calculations each year — keeping yourself below benefits thresholds while that money sits in an investment account, working for you.
That $7,500, invested in a simple low-cost index fund, participates in the same stock market that has built wealth for the upper branch of the K for generations. The market doesn't know or care whether you receive Medi-Cal. It compounds the same for everyone.
That's the same compounding that built the retirement security of the upper branch of the K. The stock market is one of the few wealth-building systems in America that doesn't check your income or your zip code before letting you in. But you have to know the door is open.
"You can earn $7,500 more, put it all in a retirement account, stay under the benefits cliff, and watch it grow in the stock market — just like everyone else."
This isn't about getting rich quick. It's about participating in the normal, legal wealth-building mechanisms that middle-class America takes for granted — while protecting the benefits your family depends on right now.
Part 5
The mechanics are simpler than they sound. Here's the path from where you are to a funded retirement account that protects your benefits:
Enter your income, household size, and county. See exactly which benefits you currently receive, which thresholds you're near, and how much a retirement contribution would shift your MAGI. This is your baseline.
Any major brokerage — Betterment, Fidelity, Schwab, or M1 Finance — lets you open a Traditional IRA online in about 10 minutes with no minimum balance. Once open, select a low-cost index fund and set up a monthly contribution.
California also offers CalSavers, the state-run retirement program for workers without employer plans. It's free, has no minimum, and starts at $5/month — a good option if you're not sure where to begin. Visit calsavers.com to learn more.
The calculator shows you the exact monthly amount that brings your MAGI below your key threshold. Start there — even $50/month adds up. You can always increase it as your income grows.
You don't need to pick stocks. A total market index fund (like FSKAX at Fidelity, VTSAX at Vanguard, or the CalSavers default fund) automatically spreads your money across thousands of companies and charges minimal fees. Set it and forget it.
Benefits thresholds are adjusted each year with the federal poverty level. Run the calculator again each January to confirm your contribution amount still keeps you protected. Increase your contribution if your income grows.
Only pre-tax contributions reduce your MAGI. A Traditional IRA uses pre-tax dollars — it reduces your MAGI dollar-for-dollar. A Roth IRA uses after-tax dollars and does not reduce your MAGI. For benefits protection, always choose Traditional.
The same applies to 401(k)s and 403(b)s through an employer — those are also pre-tax and reduce MAGI. If your employer offers one with a match, that's even better.
To be clear, Roth accounts are great — tax-free growth and tax-free withdrawals in retirement are a real advantage. They're just not the right tool for protecting your benefits today. Read more about Roth vs. Traditional →
