The ‘Official’ Story vs. The Reality

The official story you hear about claiming Social Security is straightforward. You are eligible for retirement benefits once you turn 62. If you claim before your FRA (which is typically 66 to 67, depending on your birth year), your monthly benefit is permanently reduced. If you delay claiming past your FRA, your benefit permanently increases by a set percentage each year, up to age 70.

This narrative is accurate, but it’s incomplete. It implies that any month is as good as another within a given year of your life. The reality is far more nuanced, and it hinges on a few mechanical rules that the SSA uses to process applications.

The Birthday Rule

First, let’s talk about your birthday. The SSA considers you to have attained your age for the entire month in which you were born. However, there is a peculiar exception. If your birthday falls on the 1st or 2nd of the month, the SSA treats you as if you had attained your age in the previous month. This isn’t just a fun fact; it has direct financial consequences.

For example, let’s say your 62nd birthday is on March 20th. You are considered 62 for all of March. The earliest month you can be “entitled” to a benefit is March. Since Social Security pays benefits in the month following the one for which they are due (a system called paying “in arrears”), your first payment for March would arrive in April.

Now, let’s say your 62nd birthday is on March 1st. Because of the special rule, the SSA considers you to have turned 62 for all of February. This means your first month of entitlement is February, and your first check would arrive in March. You get an entire extra month of payments simply because of your birth date.

The COLA Calculation and Its Strategic Importance

The second and more powerful reality involves the annual Cost-of-Living Adjustment, or COLA. A COLA is an increase in your Social Security benefit designed to help your purchasing power keep up with inflation. It is a cornerstone of your long-term retirement planning.

The SSA calculates the COLA based on changes in a specific inflation index, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). They compare the average CPI-W from the third quarter (July, August, September) of the current year to the third quarter of the previous year. The resulting percentage increase is the COLA for the following year.

Here is the critical piece of information: this COLA is officially applied to benefits in December and first appears in the check you receive in January. If you are not yet receiving benefits in December, you might assume you miss out on that COLA. This is where the opportunity lies. The COLAs that occur after you turn 62 are factored into your benefit amount when you eventually do claim. They are added to your primary insurance amount (PIA), which is the benefit you would receive at your FRA.

The strategy emerges when you combine this knowledge with your decision of when to claim. By strategically choosing your start month, you can ensure a potentially large COLA is applied to your highest possible benefit amount before you even receive your first check.
