The ACA premium tax credit calculator estimates the monthly subsidy and the premium left to pay from household size, MAGI, state group and the benchmark silver premium, using the HHS poverty guidelines and the IRS applicable-percentage table for the coverage year. Because the enhanced credits expired after 2025, the 400% income limit applies again for 2026 — exactly the change shoppers need explained.
Leads from a subsidy calculator arrive with household size and income already stated, which tells a Marketplace-certified agent within seconds whether the shopper is likely subsidy-eligible, near a cliff, or better served by off-exchange or employer options. Point consumers to HealthCare.gov (opens in a new tab) for official eligibility determinations.
