Strategic Decision-Making: How to Choose the Best Path for You

You don’t get to choose your COLA, but you absolutely can—and should—choose how you plan for its impact. A Cost-of-Living Adjustment doesn’t exist in a vacuum. It directly interacts with other parts of your financial life, most notably your Medicare Part B premiums. A strategic retiree anticipates this interaction, while a novice is often surprised and disappointed by it.

Let’s illustrate this with a simple numeric example comparing two retirees, Bill and Susan. Both are 68, have been retired for a few years, and receive an average Social Security benefit of $1,900 per month.

This year, the SSA announces a 3.0% COLA. Both Bill and Susan are set to receive a raise.

Bill’s Path: The Reactive Approach

Bill hears the news about the 3.0% COLA and does some quick math. 3.0% of his $1,900 benefit is $57. He’s pleased, thinking he’ll have an extra $57 each month to help with groceries. He doesn’t think much more about it.

In January, his first check of the new year arrives. He sees the gross amount has indeed increased to $1,957. But his net deposit is much smaller than he expected. He looks at his statement and sees that his Medicare Part B premium, which is automatically deducted from his Social Security benefit, has also increased. Let’s say it went up by $10 per month. Now, his net gain isn’t $57; it’s only $47. He feels deflated, as if a third of his raise was taken away before he ever saw it. He feels like the system is working against him.

Susan’s Path: The Strategic Approach

Susan hears the same news about the 3.0% COLA. Like Bill, she calculates her gross increase will be $57 per month. However, her strategic mindset immediately prompts a second question: “How will this affect my Medicare premium?”

She knows that Part B premiums are often announced shortly after the COLA, and that increases are common. She anticipates that a portion of her COLA will be consumed by this predictable expense. She budgets mentally for a net gain of perhaps $40 to $45, viewing the COLA not as a true raise but as a partial shield against rising healthcare costs. When her January statement arrives and shows the same $10 premium increase as Bill’s, she isn’t surprised or disappointed. It’s exactly what she planned for. The $47 net increase fits perfectly into her budget, and she has a realistic understanding of her cash flow.

The difference isn’t in the numbers—it’s in the mindset and the planning. But we can take this a step further. A truly savvy strategist like Susan also considers the risk of IRMAA, the Income-Related Monthly Adjustment Amount. This is a surcharge that high-income beneficiaries pay for Medicare Part B and Part D. A series of large COLAs, combined with other retirement income like pensions or IRA withdrawals, can unexpectedly push your income over the IRMAA threshold. This could cause your Medicare premiums to jump not by $10, but by $70, $170, or even more per month.

Susan, the strategist, reviews her total projected income for the coming year, including the new COLA-adjusted Social Security benefit. She checks the IRMAA brackets published by the Social Security Administration (SSA) to see if she’s close to a threshold. If she is, she might decide to adjust her withdrawal strategy from her traditional IRA to stay just under the limit, saving herself a significant amount of money. Bill, on the other hand, would be completely blindsided by a large IRMAA surcharge, seeing his entire COLA, and more, wiped out by higher premiums.

The best path is always proactive. Treat the COLA not as found money, but as one piece of a dynamic puzzle. Your job as the CEO of your retirement is to see how the pieces fit together and make moves that protect your bottom line.
