How to Use the Military Service Wage Credit Calculator
This tool covers the actual U.S. Social Security special wage credit for active-duty military service — it is not a translation of Korea's National Pension childbirth credit, which has no U.S. equivalent. Social Security has no credit tied to having children; the only extra wage credit it offers is for military service performed between 1957 and 2001, which is why this calculator focuses on that scope alone.
For service between 1957 and 1967, Social Security adds $300 in deemed wages to your earnings record for each quarter of active duty (up to $1,200 for a full year). For service between 1968 and 2001, it adds $100 in extra wages for every $300 of your actual military basic pay, capped at $1,200 per year. Service after 2001 gets no additional credit because active-duty basic pay is already fully counted as regular Social Security wages.
Select your service period, enter your years of active duty, and fill in either quarters per year or average annual basic pay depending on the period. The calculator shows the deemed wage credit added to your earnings record each year and the total over your service — this can modestly raise your Average Indexed Monthly Earnings (AIME) and, in turn, your monthly benefit.
