About the Social Security Calculator
This calculator helps estimate a Social Security retirement claiming strategy. It models claiming ages from 62 through 70, an estimated full retirement age based on birth year, monthly benefits, life expectancy, annual cost-of-living adjustment, and investment return on received payments.
Claiming age
Claiming before full retirement age generally reduces monthly retirement benefits, while delaying can increase monthly benefits.
Life expectancy
Longer life expectancy can make delayed claiming more attractive because higher benefits are received for more years.
COLA and return
COLA grows future benefits, while investment return estimates how received benefits might accumulate if saved or invested.
How to use this calculator
Enter your birth year, estimated monthly benefit at full retirement age, life expectancy, investment return, and COLA. Then compare two custom claiming ages and benefit amounts to see which option may provide more lifetime value.
