How much do 4 years in the military pay?

Understanding Active-Duty Officer Pay Over Four Years

Entering the military as a commissioned officer provides structured salary growth driven by rank and length of service. Over a four-year period, base earnings increase steadily through scheduled pay bumps and routine promotions.

For entry-level officers starting as a Second Lieutenant (O1), starting annual pay sits at $47,980.80, climbing to $60,375.60 after four years. Promoting to First Lieutenant (O2) brings starting pay to $55,281.60, which grows to $74,966.40 over the same timeframe.

Higher ranks see even stronger financial progression. A Captain (O3) earns roughly $63,979.20 with less than two years of service, rising to $85,348.80 by year four. Officers holding the rank of Major (O4) start at $72,770.40 and reach $91,108.80 after four years. Beyond base salary, service members frequently qualify for non-taxable allowances covering housing and meals, further boosting overall financial compensation.
