Gross vs. net

The headline COLA is your gross increase

For many beneficiaries, Medicare Part B is deducted directly from Social Security. The calculator compares today's gross check and Part B premium with the projected next-year amounts, then shows the difference in what reaches the bank. Hold-harmless protection can cap the premium increase for eligible beneficiaries.
