How this estimate works
You can read this before you hit Calculate. The tool is a 2026 national-average illustration, not a HealthCare.gov quote and not an insurance application.
1. COBRA is the notice number
Enter the full monthly premium from your election notice β employee share plus what the employer used to pay, usually plus a 2% administrative fee. If you only remember your old paycheck deduction, the optional estimator grosses that up. Replace it with the notice when it arrives.
2. Marketplace uses a 2026 credit table
Enhanced premium tax credits expired December 31, 2025. We apply IRS Rev. Proc. 2025-25 applicable percentages to your expected MAGI versus 2026 HHS poverty guidelines. There is generally no credit below 100% of FPL or above 400% of FPL. Details: 2026 subsidies.
3. Silver premium is a national-average illustration
We do not invent ZIP-level rates. The second-lowest-cost silver plan (SLCSP) is approximated with a 2026 national-average age curve, counting at most three children under 21. Your ZIP can be far higher or lower. Always verify at healthcare.gov.
4. State only affects Medicaid vs. gap
Expansion states typically cover adults up to 138% of FPL. Ten non-expansion states (AL, FL, GA, KS, MS, SC, TN, TX, WI, WY) can leave adults under 100% FPL in a coverage gap β no Medicaid expansion and no Marketplace credit. Formulas: methodology.
This is not insurance, tax, or legal advice. Networks, deductibles, and HSA eligibility are not in the math β they still matter. See when COBRA still wins.

The COBRA Wait Strategy
You don't have to decide today. Wait up to 60 days. If you stay healthy, enroll in ACA. If you get sick, retroactively enroll in COBRA and pay the back-premiums. It's a legal safety net few people know about. Both clocks still expire β see How it works.
60-Day Special Enrollment Window
Losing job-based coverage triggers a Special Enrollment Period (SEP). You have 60 days to enroll in an ACA Marketplace plan without waiting for open enrollment. Enrolling in COBRA does not extend that Marketplace SEP.
Income Timing Matters
If you lost your job mid-year, your annual MAGI will be lower than usual. Lower income can mean a larger 2026 credit β until you hit the 100% FPL floor or the 400% cliff. Use a realistic full-year estimate.
Check Your Doctors' Networks
COBRA keeps you on your existing plan (same doctors, same network). ACA plans may have different networks. If you have ongoing care, confirm your providers are in-network before switching.
