MetLife makes money in three ways. First, it collects premiums and fees: in FY2025, premiums, fees and other revenues (PFOs) rose 10% to $57.6B, led by US Group Benefits (employer-paid and voluntary life, dental, disability, vision and accident coverage, including the federal FEGLI program) and Retirement & Income Solutions (pension risk transfer, structured settlements, stable value and funding agreements). Second, it invests the reserves backing those policies and earns net investment income on a general account of several hundred billion dollars. Third, MetLife Investment Management earns fees managing money for outside institutions. Profit depends on underwriting margins (claims versus premiums), the spread between investment yields and what is credited to policyholders, and expense control.
