Introduction
This Army Retirement Calculator helps you estimate your military retirement pay. It covers all four retirement plans: Final Pay, High-3, REDUX, and the Blended Retirement System (BRS). Whether you are Active Duty, Army Reserve, or National Guard, this tool shows you what to expect each month after you retire.
Enter your rank, years of service, and service entry date. The calculator picks the right plan for you, looks up your base pay, and does the math step by step. It also builds a side-by-side comparison of High-3 vs. BRS so you can see which plan pays more over your lifetime. You can adjust for COLA, state taxes, disability ratings, and TSP contributions to get a clearer picture of your total retirement income.
Use this calculator to plan ahead. A few small choices now — like how much you put into TSP or how long you serve — can mean thousands of dollars more each year in retirement.
How to Use Our Army Retirement Calculator
Enter your military service details below to estimate your monthly and annual retirement pay, lifetime pension value, and how different retirement plans compare. Here is what each field means.
Service Component — Pick whether you serve on Active Duty, in the Army Reserve, or in the National Guard. This changes how your retirement pay is calculated.
Service Entry Date — Enter the date you first joined the military. The calculator uses this date to suggest the right retirement plan for you.
Total Years of Service — Enter the total number of years you will have served when you retire. Most soldiers need at least 20 years to qualify for retirement.
Age at Retirement — Enter how old you will be on the day you retire. Reserve and Guard members usually start getting paid at age 60.
Retirement Grade (Rank) — Choose the rank you expect to hold when you retire. Your rank sets your base pay, which drives your pension amount.
Years at Highest Grade — Enter how many years you will have spent at your final rank. This helps figure out your High-3 pay average.
Retirement Plan — Choose your retirement plan. The calculator suggests one based on your entry date, but you can pick a different one to compare. Final Pay, High-3, REDUX, and BRS each use a different formula.
Custom High-3 Average — If you know your exact 36-month pay average, type it here. Leave this blank to let the calculator estimate it for you.
CSB/REDUX Election — Check this box if you took the $30,000 Career Status Bonus at 15 years of service. This only applies to the REDUX plan.
Govt TSP Contribution % — For BRS only. Enter the total government contribution to your Thrift Savings Plan, up to 5%.
Member TSP Contribution % — For BRS only. Enter the percentage of your base pay that you put into your TSP each month.
Estimated TSP Balance at Retirement — For BRS only. Enter how much you expect to have in your TSP account when you retire.
Continuation Pay — For BRS only. Enter the one-time bonus you received or expect to receive at your 12-year mark.
Total Retirement Points — For Reserve and Guard only. Enter your total retirement points. You earn points from drills, active duty days, and membership years.
Qualifying Years — For Reserve and Guard only. Enter the number of years where you earned 50 or more points. You need at least 20 qualifying years to retire.
Pay Commencement Age — For Reserve and Guard only. Enter the age when your retirement pay will start. This is usually 60 but can be lower with qualifying active service.
DoD Disability Rating — Turn on the Medical Retirement section and slide to your DoD disability rating. This is separate from any VA rating you may have.
Annual COLA — Slide to set the yearly cost-of-living adjustment you expect. The default is 2.5%, which is a common estimate.
Life Expectancy — Slide to the age you want the calculator to project through. This affects your lifetime pension total.
State of Residence — Pick the state where you plan to live after you retire. Many states do not tax military retirement pay at all.
State Income Tax Rate — This fills in automatically when you pick a state. You can change it if your situation is different.
Once all your information is entered, click the Calculate button to see your results. The calculator will show your estimated monthly and annual pay, a step-by-step breakdown of the math, a COLA projection table, and a side-by-side comparison of BRS versus High-3.
How Army Retirement Pay Works
When you serve in the U.S. Army for 20 or more years, you earn a monthly pension for the rest of your life. This is called military retirement pay. The amount you get depends on your rank, how long you served, and which retirement plan applies to you.
The Four Retirement Plans
There are four military retirement plans. The one you fall under depends on when you first joined the service.
Final Pay is for members who entered service before September 8, 1980. It uses your last base pay and multiplies it by 2.5% for each year you served. For example, 20 years of service gives you 50% of your final base pay.
High-3 is for members who entered between 1980 and 2017. Instead of your final paycheck, it uses the average of your highest 36 months of base pay. The multiplier is the same — 2.5% per year.
REDUX applies to members who entered between 1986 and 2002 and chose the Career Status Bonus (CSB). You get a $30,000 bonus at 15 years of service, but your retirement multiplier is reduced and your cost-of-living adjustments are smaller until age 62.
Blended Retirement System (BRS) is for anyone who joined on or after January 1, 2018. It uses a lower multiplier of 2.0% per year but adds government contributions to your Thrift Savings Plan (TSP). You also receive continuation pay at 12 years of service.
Reserve and National Guard Retirement
If you serve in the Army Reserve or National Guard, your retirement pay is based on points instead of years. You earn points through drills, active duty days, and membership. You divide your total points by 360 to get your equivalent years of service. You need at least 20 qualifying years to retire, and pay usually starts at age 60.
Medical and Disability Retirement
If you leave the Army due to a medical condition, you may qualify for disability retirement. You need a DoD disability rating of at least 30%. Your pay is either based on your disability percentage or your years of service — whichever amount is higher.
Cost-of-Living Adjustments (COLA)
Military retirement pay goes up each year to keep pace with inflation. This increase is called a cost-of-living adjustment, or COLA. Under most plans, COLA matches the Consumer Price Index. Under REDUX, the adjustment is 1% less than full COLA until you turn 62.
State Taxes on Military Retirement
Federal taxes apply to military retirement pay, but state taxes vary. Many states fully exempt military pensions from state income tax. Some states tax it partially, and a few tax it fully. Where you live in retirement can make a real difference in your take-home pay.
