Talk:Income-Related Monthly Adjustment Amount (IRMAA)

IRMAA table tiers
I don't understand how to calculate the entries in the "Marginal Annual Cost at Top of Tier" and "Marginal Tax Rate for Traversing Entire Tier" columns. Is this in a spreadsheet? If so, please link the spreadsheet as a citation reference.

Also note that this page will have to be updated annually.
