If There's Any Number to Know About Social Security, Make It This One
Unfortunately, Social Security isn't the most straightforward program. There are constant changes and complexities that can sometimes leave retirees with more questions than answers. Considering the vital role Social Security plays in many people's retirement, that shouldn't be the case.
While this complexity isn't likely to change, the one thing retirees can do is cut out the noise and focus on the handful of details that matter the most. If there's one number to focus on regarding Social Security -- particularly in helping you decide when to claim benefits -- it should be your break-even age.
Your break-even age is when the total amount received from claiming Social Security at your full retirement age (FRA) or earlier equals the total amount received by delaying benefits.
