The official marketplace tool and independent subsidy calculators don’t always pull from the same numbers.

Federal guidelines update once a year, but not every calculator updates on the same schedule.

Standard utility allowances vary by state and even by heating type, details most national tools skip entirely.

Broad-based categorical eligibility can bypass standard income tests, a workaround many calculators don’t model at all.

Words like ‘may qualify,’ ‘appears eligible,’ and ‘possible match’ each signal a different level of certainty.

Whether child support counted as income at all depended entirely on which tool was asked.
