ACA Subsidy Calculator for Ages 62-64
Retire or lose employer coverage before 65, and you're on your own for health insurance until Medicare kicks in. Estimate how much help you'd get toward a Marketplace plan under 2026's rules — including the subsidy cliff that came back this year.
For 2026, the temporary enhanced ACA subsidies expired and the original rules are back: your premium tax credit depends on your household income as a percentage of the federal poverty line (FPL), using the IRS's applicable percentage table to set your expected contribution. Income above 400% of FPL generally means $0 in credit, no matter how expensive the plan — the "subsidy cliff" that was suspended from 2021-2025 is back in effect. This matters most for early retirees ages 62-64: Social Security income counts in full toward this calculation, even the untaxed portion, so claiming benefits early can meaningfully shrink your subsidy.
The years between an early retirement and Medicare eligibility at 65 are the one stretch where most people in this age group have to buy health insurance entirely on their own. This calculator walks through the actual federal formula — not a rough estimate — so you know what to expect before you're comparing plans on healthcare.gov.

Several states (California, Massachusetts, New York, New Jersey, Washington, Connecticut, Vermont, Colorado, Maryland, and New Mexico among them) fund their own additional subsidies on top of the federal credit calculated here, especially at lower incomes. Check your state's own exchange — this tool only calculates the federal amount.
For 2021 through 2025, temporary enhancements from the American Rescue Plan and Inflation Reduction Act removed the income cap on subsidies entirely and capped the required contribution at a lower rate. Congress didn't extend those enhancements past 2025, so 2026 reverts to the original, pre-2021 rules: a hard cutoff at 400% of the federal poverty line, and a steeper required-contribution schedule below it. For someone right at the edge of that cutoff, even a modest income increase — a larger RMD, a Roth conversion, claiming Social Security earlier than planned — can mean the difference between a meaningful subsidy and none at all. This is exactly the kind of income-timing decision worth running through a planner or tax preparer before locking in, not after.
The math itself has two moving parts. First, your household income is measured against the federal poverty line for your household size to get a percentage — 150% of FPL, 250% of FPL, and so on. Second, the IRS's applicable percentage table (updated annually, and higher for 2026 than in the enhanced-subsidy years) sets what portion of that income you're expected to contribute toward the benchmark plan, sliding from 2.10% near the bottom of the eligible range up to 9.96% at the top. The premium tax credit is simply the gap between that expected contribution and the benchmark plan's actual cost. You can apply the credit to any plan tier, not just the benchmark Silver plan — a cheaper Bronze plan might cost less than your credit, while a pricier Gold plan would cost more out of pocket.
The Social Security detail catches a lot of early retirees off guard. Regular federal income tax only taxes up to 85% of Social Security benefits, and sometimes none of it, depending on your other income. ACA MAGI doesn't work that way — it adds back 100% of your Social Security benefits regardless of the taxable portion. That means two people with identical take-home income could have very different measured MAGI for subsidy purposes if one relies more heavily on Social Security than the other. It's a genuine planning variable, not just a calculation footnote.
Frequently Asked Questions
How is the ACA premium tax credit calculated for 2026?
Your household income (MAGI) is compared to the federal poverty line (FPL) for your household size to find your income as a percentage of FPL. The IRS applicable percentage table sets what share of that income you're expected to pay toward the benchmark (second-lowest-cost Silver) plan. The premium tax credit is the benchmark plan's premium minus that expected contribution.
Is the ACA subsidy cliff back for 2026?
Yes. The temporary enhanced subsidies from the American Rescue Plan and Inflation Reduction Act expired at the end of 2025. For 2026, household income above 400% of the federal poverty line generally means $0 in premium tax credit, no matter how high the actual premium is — the original pre-2021 rules are back in effect.
Does Social Security income count toward ACA subsidy eligibility?
Yes, and this trips up a lot of early retirees. ACA MAGI counts the full amount of Social Security benefits received, including the portion that isn't taxable under regular income tax rules — not just the taxable share. If you've already claimed Social Security before 65, all of it counts here.
What if my income is below 100% of the poverty line?
Generally, marketplace premium tax credits require income at or above 100% of FPL — below that, you're expected to qualify for Medicaid instead. In the states that didn't expand Medicaid, this can create a "coverage gap" where income is too low for marketplace subsidies but too high for that state's traditional Medicaid rules. Check Medicaid eligibility directly if this applies to you.
Do all states use the same subsidy rules?
The premium tax credit calculated here is federal and identical in every state. Several states — including California, Massachusetts, New York, New Jersey, Washington, Connecticut, Vermont, Colorado, Maryland, and New Mexico — layer their own additional state-funded subsidies on top for 2026. Check your state's exchange directly to see if you qualify for extra help beyond what this calculator shows.
Uses the IRS's 2026 Applicable Percentage Table (Rev. Proc. 2025-25) and the 2025 HHS federal poverty guidelines (the guidelines in effect for 2026 Marketplace enrollment). Assumes full-year coverage — if you'll turn 65 and move to Medicare partway through 2026, your actual credit is prorated for the months you're enrolled in a Marketplace plan, which this tool doesn't calculate. It also doesn't include any state-funded supplemental subsidy your state may offer on top of the federal amount. This is a planning estimate, not a Marketplace determination — get your exact figure at healthcare.gov or your state exchange when you apply.
