A $400,000 annuity crosses into genuine income-replacement territory — generating $2,425–$2,866/month at age 65 depending on rate. Combined with Social Security, it lifts most households above their essential expense line on guaranteed income alone. Major 401(k) rollover, pension lump-sum election, sale of a rental property, or consolidated retirement accounts are among the most common sources for a $400,000 annuity purchase. At age 65 and a 5% credited rate over 20 years, a $400,000 annuity generates approximately $2,640/month.
