What is MAGI?

MAGI stands for Modified Adjusted Gross Income. It's a tax term — a specific way the IRS measures your income. MAGI determines your tax bracket, whether you can contribute to a Roth IRA, how much of your Social Security gets taxed, and — critically for early retirees — how much you pay for health insurance. The higher your MAGI, the less help you get.

The key insight: your MAGI is often much higher than your paycheck. It includes dividends from your investments, interest from your savings, every dollar you withdraw from a Traditional IRA, and every dollar you convert to a Roth. Many early retirees are surprised to learn that money they're simply moving between accounts — not spending — is raising their MAGI and costing them thousands in lost health insurance subsidies.

Why It Matters: The Subsidy Cliff

If you buy health insurance through the ACA marketplace (Obamacare) before age 65, the government subsidizes your premiums — but only if your MAGI stays below 400% of the Federal Poverty Level.

The cliff: In 2026, if your MAGI goes even $1 over the threshold, you lose your entire subsidy and pay full price. For a 57-year-old couple, that's the difference between paying $7,000/yr and $36,000/yr for the same coverage.
Household 400% FPL Threshold (2026)
Single $61,600
Couple (no dependents) $83,600
Family of 4 $127,600

What Counts as MAGI

Every dollar from these sources pushes your MAGI higher and closer to the cliff:

Income Source MAGI Impact Can You Control It?
Traditional IRA / 401(k) withdrawals Dollar-for-dollar Yes — main lever
Roth conversions Dollar-for-dollar Yes — timing + amount
Capital gains from selling investments Dollar-for-dollar Yes — choose which lots
Employment / self-employment income Dollar-for-dollar Partially
Taxable dividends & interest Dollar-for-dollar Partially
Social Security benefits Up to 85% No (once claimed)
Pension income Dollar-for-dollar No

What Does NOT Count as MAGI

These are your secret weapons. You can spend this money without raising your MAGI at all:

Source MAGI Impact
Roth IRA / Roth 401(k) withdrawals $0 — completely invisible
Return of basis from taxable accounts $0 — only gains count
HSA withdrawals (for medical expenses) $0
Loans (HELOC, margin, etc.) $0
The strategy in one sentence: Fund your living expenses from Roth withdrawals and taxable account basis, while keeping Traditional IRA withdrawals below the subsidy cliff.

What This Looks Like in Practice

Here's a real example: a couple, both age 57, with $1.5M across multiple account types. They need $90,000/yr for living expenses.

Without MAGI Awareness

  • Pulls $90,000 from Traditional IRA
  • MAGI = $90,000
  • Above cliff ($83,600)
  • No subsidy — full premium
Healthcare: $35,904/yr

With MAGI Awareness

  • $40,000 from Traditional IRA
  • $30,000 from Roth (no MAGI impact)
  • $20,000 from taxable account
  • MAGI = $80,000 — below cliff
Healthcare: $6,800/yr
$29,104 / year
saved in healthcare costs — same spending, different source

Over 8 years (age 57 to 65, when Medicare begins), that adds up:

Year Age Without MAGI Awareness With MAGI Awareness Saved
157$35,904$6,800$29,104
258$36,768$6,900$29,868
359$37,680$7,000$30,680
460$40,704$7,200$33,504
561$41,712$7,300$34,412
662$43,080$7,500$35,580
763$44,136$7,600$36,536
864$45,000$7,800$37,200
Total $324,984 $58,100 $266,884

The same couple, spending the same amount, saves over a quarter million dollars in healthcare costs just by choosing which accounts to pull from. The money was always there — the difference is the order.

Bonus: Roth Conversions During the ACA Window

If your MAGI is well below the cliff, you have room to convert Traditional IRA money into a Roth IRA. This raises your MAGI now (but you stay below the cliff), and it reduces your future tax burden when Required Minimum Distributions (RMDs) kick in at age 73.

In the example above, the couple has MAGI of $80,000 with a cliff at $83,600. They could convert up to ~$3,600 more to Roth each year and still keep their subsidy. Over 8 years, that's ~$29,000 moved from a taxable account to a tax-free account — on top of the healthcare savings.

Important: Roth conversions count as MAGI. If you're doing conversions, factor them into your cliff calculation. This is where getting the numbers right matters — a $1,000 miscalculation can cost you $29,000 in lost subsidies.

Your Quick Checklist

# Action
1 Know your cliff number. Look up 400% FPL for your household size.
2 Add up your unavoidable MAGI. Pension, Social Security, dividends — what can't you change?
3 Calculate your MAGI room. Cliff minus unavoidable MAGI = how much you can pull from Traditional accounts.
4 Fill the gap from Roth + taxable. Whatever spending your Traditional withdrawals don't cover, pull from MAGI-free sources.
5 Use leftover MAGI room for Roth conversions. If you're below the cliff, convert the remaining room to reduce future taxes.
