Military retirement after 20 years

Military retirement after 20 years pays 50% of your High-3 average basic pay under the High-3 system and 40% under the Blended Retirement System: $2,750 or $2,200 a month on a $5,500 High-3, before tax and SBP. Below: the amount at other High-3 levels, the SBP cost, the BRS lump sum and a calculator set to 20 years.

Short answer: 50% of your High-3 average basic pay under the High-3 system (2.5% a year) and 40% under the Blended Retirement System (2% a year). On a $5,500 High-3 that is $2,750 or $2,200 a month before tax and SBP, paid from the month after you retire at any age and raised each December for inflation.

Why 20 years pays 50%

Each year of service earns 2.5% of your High-3 under the High-3 system and 2% under BRS, so 20 years is 20 × 2.5% = 50%, or 20 × 2% = 40%. Two fewer years (18) would pay 45% or 36%; two more (22) would pay 55% or 44%. Service past 30 years keeps counting up to 40, and retired pay rises each December by the change in consumer prices.

After the Survivor Benefit Plan

SBP spouse coverage on full retired pay costs 6.5% of it and pays your surviving spouse 55% for life. Premiums stop once you have paid 360 months and reached 70.

The BRS lump sum

Under BRS you can take 25% or 50% of your retired pay up to Social Security’s full retirement age as a discounted lump sum; the monthly check is 75% or 50% of normal until then and returns to the full amount after. At 20 years on a $5,500 High-3, that means $1,650 or $1,100 a month instead of $2,200 until that age. The pension vs lump sum calculator shows what return a lump sum would need to keep up.

The calculator, set to 20 years

Enter your own High-3 and choose BRS or High-3. The full military retirement calculator page covers every rule.

TSP, Social Security and a second career

Retiring after 20 years usually leaves years of work and saving before Social Security. Federal civilian work can add a pension of its own: see the FERS retirement calculator.
