If you are planning your retirement, the most critical question you might ask is: does social security use months to calculate benefits? The answer is a definitive yes.

Many retirees believe that if they wait from age 66 to age 67, they only get an annual bump. In reality, for every month you delay, your benefit increases by a small fraction.
