I’m not sure what your question is exactly but there is a finite amount of money in your social security “bank” and that amount is based on what you paid into social securityduring your working years. So, if you start drawing social security benefits at a younger age, your monthly check will be less but you will recieve this monthly checks for a longer period of time. If you start drawing your social security at an older age, your monthly checks will be more, but for a shorter period of time.
