What This Calculator Does
This military retirement pay calculator compares the three Department of War retirement systems: High-36 (legacy system for members who entered before 2018), Blended Retirement System or BRS (for members who entered 2018 or later), and REDUX (Career Status Bonus option at 15 years). It calculates your monthly and annual retirement pay based on years of service and your High-36 average (the average of your highest 36 months of base pay). For BRS members, it models Thrift Savings Plan (TSP) contributions with government matching and projects retirement account value. The calculator shows the 2026 retired pay with 2.8% COLA increase and helps you compare retirement systems to make informed career decisions.
The Formula
The High-36 retirement formula multiplies 2.5% by your years of creditable service by your High-36 average base pay. For 20 years, you receive 50% of your High-36 average; for 30 years, 75%. The BRS uses 2.0% instead of 2.5%, resulting in a smaller pension (40% at 20 years, 60% at 30 years), but adds TSP government matching up to 5% of base pay and a continuation bonus at 12 years. REDUX also uses 2.0% but provides a $30,000 Career Status Bonus at 15 years in exchange for the reduced multiplier; at age 62, your pension is restored to the High-36 equivalent. All three systems calculate your High-36 average by taking the 36 consecutive months of highest base pay (usually your final 3 years) and averaging them.
Step-by-Step Example
Determine your retirement system
If you entered service before January 1, 2018, you are under High-36 (unless you opted into BRS during the 2018 opt-in period). If you entered on or after January 1, 2018, you are automatically in BRS.
Calculate High-36 average
Add your monthly base pay for the highest 36 consecutive months of service, then divide by 36. For an E-7 retiring in 2026 after 24 years, the final 36 months averaged $5,800/month.
Apply the formula
High-36: 2.5% x 24 years = 60% multiplier. $5,800 x 60% = $3,480/month retirement pay. BRS: 2.0% x 24 years = 48% multiplier. $5,800 x 48% = $2,784/month, but add TSP account and continuation bonus.
Include TSP for BRS
If you contributed 5% to TSP throughout your career and received 5% government match at a 7% annual return, your TSP could be worth $250,000 to $400,000+ at retirement, offsetting the smaller pension.
Real-World Use Cases
20-Year Retirement Planning
Service members approaching 20 years use the calculator to estimate their immediate retirement pay and determine if they can afford to retire or should continue to 25 or 30 years for a higher pension.
BRS vs High-36 Comparison
Service members who entered during the 2018 BRS opt-in window compare projected outcomes under each system by modeling TSP growth, continuation bonus, and pension amounts to make an informed election decision.
REDUX Career Status Bonus Decision
Service members at 15 years of service evaluate whether to accept the $30,000 REDUX Career Status Bonus in exchange for reduced retirement pay from 2.5% to 2.0% multiplier until age 62, considering time value of money and career intentions.
Common Mistakes to Avoid
Confusing base pay with total compensation when calculating High-36. Only base pay counts, not BAH, BAS, special pays, or bonuses. Your High-36 average is typically $4,000 to $8,000/month depending on rank.
Forgetting to contribute to TSP if you are in BRS. You must contribute at least 5% of base pay to receive the full 5% government match. Not contributing means you forfeit free money that could be worth $200,000+ at retirement.
Not accounting for COLA. Retiree COLA is based on CPI and adjusts annually. The 2026 COLA is 2.8%, but future years will vary. REDUX retirees receive CPI minus 1% COLA until age 62.
Assuming you can change systems after retirement. Your retirement system is locked when you hit 12 years of service (BRS continuation pay election) or when you separate. You cannot switch from High-36 to BRS after retiring.
Forgetting about the Survivor Benefit Plan (SBP). Retired pay stops at death unless you elect SBP, which provides 55% of your retired pay to your surviving spouse for a monthly premium of 6.5% of your retired pay.
