What it did to a Social Security payment
The Part B premium is withheld from the Social Security payment, so it lands in the same January as the cost-of-living adjustment and the two move against each other. A $2,000 monthly benefit in 2020 became $2,026 gross with the 1.3% adjustment — a rise of +$26. After the premium went from $144.60 to $148.50, the payment rose +$22, an effective 1.19%.
