There are three military retirement calculators, namely: “Final pay,” “High-3” and “Career Status Bonus/Redux.” The retired pay will differ from one military retirement calculator to another this variation depends on the years of your service with the military.
Let’s see how the Career Status Bonus/Redux system works:
The most important thing is to determine the exact day you entered the military service. So, you entered military service after 31 of July, 1986 you can use the Redux/ Career Status Bonus military retirement calculator to determine your retired pay.
This military retirement calculator gives you the possibility to make tables that would illustrate your situation. When calculating the retired pay there are several variables that are used by in this calculator that is the number of years in US army, the age, the retirement grade and the sum of 30.000 US dollars, called Career Status Bonus. Moreover, the REDUX calculator permits you to change the inflation rate accordingly and the expected return that you may gain from the bonus money which were invested.
Let’s see some possible scenarios that could resemble your situation.
At the 15th year of service the Redux retirees are entitled to receive the so called Career Status Bonus of 30.000 US dollars. If you have served 20 years in the US army, your retired pay will be lower, namely, the legal formula in this case will represent 40% of the average of the base pay together with the 3 highest earnings during the years in the army.
In case of between 20 and 30 years of military service the Redux retirees’ retired pay will be calculated by using 2.5 % 
for one year of service, however, you should subtract 1 percentage point for each year of military service which is shorter than 30 years. For example, you have 25 years of military service, so you multiply your number of years in the US army with 2.5 % but then reduce the result with 5 points because 5 years are short of 30 years. So your retired pay with Redux plan will constitute 57.5 percent. This percentage is calculated in relation to your average basic pay together with the highest earnings gained in three years of military service.
If you have 30 years of military service then under the military retirement calculator Redux you simply have to multiply number of your years in the active service with 2.5 %, which will constitute already 75% of your average basic pay together with the highest earnings in three years in uniform.
But if you have more than 30 years of military service then you multiply your number of your years in the active service with 2.5 % for each year of service.
If your number of your years in the active service with military reaches 40 years then under the Redux system you would have 100 % of your average basic pay of those 3 years, when you had highest earnings.
