How it works

Most pensions cut your monthly benefit a fixed percentage for every year you claim before full retirement age — claiming five years early at 5% a year is a 25% permanent cut. This shows your reduced check, the monthly and percentage cut, and the lifetime trade-off: more years of smaller checks by starting early, versus fewer years of larger checks by waiting.
