2027 irmaa brackets: Medicare Cost And Irmaa Table

Every row is a verbatim sentence read from the named source's own page through the estate's fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

2 of the 5 named sources that could be read published a usable figure; 2 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 30 candidate sentence(s) were refused by a reviewer with the reason recorded.

Derivation as chartered: one row per figure per year, quoted verbatim from the authority that sets it with its effective date: the Part A deductible and coinsurance, the Part B standard premium and deductible, every IRMAA bracket for Part B and Part D with its MAGI threshold and dollar surcharge, the 15% limiting charge, and the deductibility rule with its 7.5%-of-AGI floor.

What is ours is the SERIES: every figure back-dated year on year, the percentage change at each rate turn, the share of the Social Security COLA a premium rise consumes, and the bracket a given MAGI lands in two years later - the calculator is generated from the table, never typed.

30 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
