I would think the exact calculation would be available online, however I haven't found it. For married filing jointly, the maximum MAGI before any increase in Part B and Prescription Drug premiums, increased from $174,000. to $176,000. I know the calculation rounds to the nearest thousand, however, I'd like to see the calculation so I can estimate the increase/decrease next year.
I think it's based on the CPI increase, however, I don't know how to check the arithmetic. I'm hoping someone can show me the calculation. Thank you.
