A free, open-source Social Security strategy calculator
Your primary insurance amount (PIA) is the amount of your monthly retirement benefit, if you file for it at your full retirement age. You can get an estimate of your PIA from your Social Security statement. You can also call the SSA to request that they calculate your PIA, or you can calculate it yourself with the calculator at SSA.tools or the SSA's "Any PIA" calculator.
