Understanding the Calculator Results
The calculator displays four important values.
1. Longevity Retirement
This represents retirement pay based solely on:
- Years of service
- Retirement multiplier
- Monthly base pay
Longer military careers generally produce higher longevity retirement payments.
2. Disability Retirement
This amount is calculated using your disability rating and monthly base pay.
Generally speaking, a higher disability percentage results in a higher estimated disability retirement amount.
3. Estimated Monthly Retirement
The calculator compares both retirement methods and displays the larger estimated monthly benefit.
This provides a quick comparison of which calculation produces the higher retirement estimate.
4. Method Used
The calculator identifies which method generated the estimated retirement amount:
- Longevity Method
- Disability Percentage Method
This makes it easy to understand how the estimate was determined.
Military Disability Retirement Formula Explained
The calculator uses two separate calculations.
Longevity Retirement Formula
Longevity Retirement = Monthly Base Pay × (Years of Service × Retirement Multiplier)
If the calculated percentage exceeds 75%, it is capped at 75% within the calculator.
Example
Monthly Base Pay:
$6,000
Years of Service:
20
Multiplier:
2.5%
Retirement Percentage:
20 × 2.5 = 50%
Estimated Longevity Retirement:
$6,000 × 50%
= $3,000 per month
Disability Retirement Formula
The disability retirement estimate is based on:
Disability Retirement = Monthly Base Pay × Disability Rating
Example
Monthly Base Pay:
$6,000
Disability Rating:
60%
Estimated Disability Retirement:
$6,000 × 60%
= $3,600 per month
Final Retirement Estimate
The calculator compares both amounts.
Example:
Longevity Retirement:
$3,000
Disability Retirement:
$3,600
Estimated Monthly Retirement:
$3,600
Method Used:
Disability Percentage Method
Complete Example
Suppose a service member enters:
- Monthly Base Pay: $5,800
- Years of Service: 18
- Disability Rating: 50%
- Retirement Multiplier: 2.5%
Step 1
Longevity Percentage:
18 × 2.5
= 45%
Step 2
Longevity Retirement:
$5,800 × 45%
= $2,610
Step 3
Disability Retirement:
$5,800 × 50%
= $2,900
Step 4
Comparison
Longevity:
$2,610
Disability:
$2,900
Estimated Monthly Retirement:
$2,900
Method Used:
Disability Percentage Method

Common Mistakes to Avoid
Many users accidentally reduce estimate accuracy by making simple mistakes.
Avoid these common errors:

- Using an incorrect disability percentage
- Forgetting partial years of service
- Selecting the wrong retirement multiplier
- Assuming estimates are official benefit determinations
- Ignoring future changes to retirement regulations
Why Compare Both Retirement Methods?
Comparing both methods helps you understand how different factors influence retirement pay.
For example:
Someone with many years of service but a lower disability rating may receive a higher estimate under the Longevity Method.
On the other hand, someone with fewer years of service but a higher disability rating may receive a larger estimate under the Disability Percentage Method.
Displaying both values provides a clearer picture of potential retirement income.
