Enter each person's business income, expenses and W-2 wages. The estimator builds MAGI step by step, shows where you sit against the 400% poverty-line cliff, and estimates your credit and net monthly premium.
You don't need to apply for coverage first. You'll need three numbers (and a fourth, optional one if you're already enrolled). Each field below has a “How do I find this?” link.
A good order: look up your prices, use this estimator to see how your income and deductions change your credit, then apply (or update your application) with your best honest estimate of income. If you've already applied, you can use this to double-check your numbers. Using it doesn't enroll you in anything, and your numbers stay in your browser. The one exception is the optional benchmark lookup, which sends only your ZIP code and ages (not your income).
Optional. This sends only your ZIP code and ages (not your income) to HealthCare.gov’s public plan data through my website, and nothing is saved. You can always skip it and type your own number below.
What it is: the monthly price of the second-lowest-cost Silver plan in your area, for everyone in your household who would be covered. The credit is based on this price, not on the plan you pick.
You don't need to apply first. Choose the case that fits you:
The full monthly price of the plan you have or are considering, before any credit. Find it in your Marketplace account's plan details, or on the plan's page when you browse plans. If the price shown is after a credit, look for the total or full premium.
This only applies if you're already enrolled and get part of your premium paid each month by a tax credit. Leave it blank if you haven't enrolled yet, or if you chose not to take the credit in advance.
If you updated your income estimate during the year, use your current amount. It may have changed.
Menu names change. If a label doesn't match, look for “see plans,” “preview plans,” or “window shopping.” Stuck? free local help can find it with you.
Box 1 of a W-2 already leaves out pre-tax 401(k)/403(b) deferrals and HSA contributions made through payroll. Enter Box 1 and don't list those contributions again in step 3, or they'd be subtracted twice.
Retirement: SEP-IRA, solo 401(k) (employee and employer sides) and deductible traditional IRA. As of November 12, 2026 the IRS hadn't announced 2027 retirement limits (they're usually published in mid-November), so check the IRS announcement. For reference, the 2026 limits are \1. A traditional IRA deduction can phase out if you're also covered by a workplace plan. HSA: only with an HSA-eligible plan; the 2027 limit for your coverage type is shown under each HSA box. Other adjustments: student loan interest, educator expenses and similar Schedule 1 items. Verify limits with the IRS before relying on them.
The deduction can't be more than your net business profit, minus the half-SE-tax deduction and self-employed retirement contributions from that business. This estimator adds those amounts for both people. If the plan runs through only one spouse's business, the true cap can be lower. For an S corporation owner, the cap is the W-2 salary instead, and the premiums must be reported on that W-2 (Box 1) for the deduction to be allowed. No SEHI deduction is allowed for any month you could have joined an employer-subsidized plan through your own job, your spouse's, a dependent's, or a child under 27's, even if you turned it down. The estimator assumes that wasn't the case for any month. Treat it as a close estimate, not the Form 7206 result.
Current law (as of November 12, 2026): the enhanced subsidies that were in place through 2025 have expired, and I'm not aware of any law that restores them. Congress has debated extending them, but as far as I can tell it hasn't become law. Above 400% of the poverty line, current law gives no credit. Check the latest news before you enroll.
What changes from 2026 to 2027:
Married filing separately: generally not eligible for the credit. The IRS allows a narrow exception for victims of domestic abuse or spousal abandonment (see Publication 974).
Figures used: applicable percentages from IRS Rev. Proc. 2026-26 (2.15% below 133% of the poverty line, rising to 10.22% from 300–400%); 2026 HHS poverty guidelines (used for 2027 coverage); 2027 Social Security wage base $192,300 (reduced by each person's W-2 wages); 2027 HSA limits of $4,500 self-only and $9,000 family from IRS Rev. Proc. 2026-24. This estimator covers the 2027 coverage year. Plans for 2028 will use updated percentages and poverty guidelines.
