CRSC Pay Calculator: Estimate Combat-Related Special Compensation
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.
Created by Luis Gonzalez · Last updated October 24, 2026
Combat-Related Special Compensation (CRSC) is a tax-free monthly benefit for eligible military retirees whose VA-rated disabilities are connected to combat-related circumstances. It can restore some or all of military retired pay otherwise waived to receive VA disability compensation. The amount depends on eligibility, the combat-related rating approved by the service branch, VA compensation rates, and the retired-pay offset.
Using the calculator’s default inputs—$2,500 monthly retired pay, a 70% VA disability rating, a 50% combat-related rating, 20 years of service, and no dependents—the estimate is $1,095 monthly CRSC, $1,748 monthly VA compensation, $1,847 net retired pay, and $3,595 total monthly income. These are calculator estimates, not an award decision. Your service branch determines whether disabilities qualify as combat-related, and official payment calculations can differ.
Use this estimate alongside the military retirement pay calculator to review retired pay, and compare it with the military retirement calculator if you are still assessing your overall benefit.
Enter ratings and retired pay
Enter monthly retired pay before the VA waiver, your overall VA disability rating, and the combat-related disability rating. The calculator limits the combat-related rating to the lower of the two ratings entered. Add dependents because VA compensation rates vary with dependent status.
The years of service input is included in the interface, but the supplied calculation does not use it to determine CRSC. The model uses monthly retired pay as entered and does not calculate the service-based longevity limit that may apply in an official CRSC determination. For that reason, do not treat this estimate as a substitute for a branch-level calculation.
The result cards distinguish four amounts:
- CRSC Payment: the modeled tax-free replacement amount.
- VA Compensation: the estimated VA disability compensation amount.
- Net Retired Pay: retired pay remaining after the VA offset, plus modeled CRSC.
- Total Monthly: net retired pay plus VA compensation.
The calculator also estimates annual CRSC and tax savings using a flat 22% assumption. That assumption is an illustration, not your individual marginal tax rate.
Default example: how the estimate is built
For the defaults, the calculator uses $1,748 as the estimated VA compensation for a 70% rating with no dependents. It estimates $1,095 of compensation associated with the 50% combat-related rating.
The modeled VA offset is the smaller of retired pay and total VA compensation:
$2,500 retired pay versus $1,748 VA compensation gives an offset of $1,748.
The CRSC estimate is capped at the smaller of the VA offset and compensation associated with the combat-related rating:
$1,748 offset versus $1,095 combat-related compensation gives $1,095 CRSC.
Net retired pay is:
$2,500 − $1,748 + $1,095 = $1,847 per month.
Total monthly income is:
$1,847 net retired pay + $1,748 VA compensation = $3,595.
The model reports annual CRSC of $13,140. Its tax-savings estimate is $13,140 × 22% = $2,890.80, rounded to $2,891 per year. Actual tax savings depend on the taxable income you would otherwise have received and your tax situation. CRSC is generally tax-free, but the calculator does not prepare a tax return.
CRSC eligibility and payment rules
A VA disability rating alone does not establish CRSC eligibility. The disability must meet the service branch’s combat-related criteria, such as an injury connected to armed conflict, hazardous service, simulated war, or an instrumentality of war. You apply through your military service branch, which reviews the evidence and decides which conditions qualify. The Defense Finance and Accounting Service CRSC guidance explains the application and payment process.
CRSC is distinct from Concurrent Retirement and Disability Pay (CRDP). CRDP restores waived retired pay for qualifying retirees but is generally taxable; CRSC is tied to approved combat-related disabilities and is tax-free. Eligibility and election rules can depend on your service history and circumstances. Read the DFAS comparison of CRSC and CRDP and review your branch’s instructions before deciding.
The calculator applies these simplified caps:
VA offset = the smaller of monthly retired pay or VA compensation
CRSC estimate = the smaller of the VA offset or combat-related VA compensation
Net retired pay = monthly retired pay − VA offset + CRSC estimate
Total monthly income = net retired pay + VA compensation
These formulas help explain the result cards, but official CRSC calculations may include additional statutory limits and service-specific details. In particular, the supplied calculator logic does not use the years-of-service input. It also does not independently determine the approved combat-related percentage or eligibility.
Compare possible rating inputs
The table illustrates how changing one input affects the estimate qualitatively. Exact payments require the current VA compensation table and your dependent status.
| Scenario | VA disability rating | Combat-related rating | Dependents | Likely effect on modeled CRSC |
|---|---|---|---|---|
| Lower combat-related share | 70% | 30% | 0 | Lower combat-related compensation cap |
| Default inputs | 70% | 50% | 0 | Calculator estimate: $1,095 monthly |
| Combat-related rating matches VA rating | 70% | 70% | 0 | Higher potential cap, subject to retired-pay offset |
| Add eligible dependents | 70% | 50% | 1 | VA compensation table amount changes |
This is not a table of official award amounts. Dependents, rating combinations, special monthly compensation, and statutory caps can change actual payments. For current rates, use the VA disability compensation rates and confirm which year’s table applies.
Interpreting the tax and income estimate
CRSC’s tax-free treatment can make a dollar of CRSC different from a dollar of taxable retired pay. The calculator’s annual savings figure uses a single 22% assumed tax rate. It does not calculate federal or state tax brackets, deductions, filing status, other income, or how a CRSC award might affect a prior tax year.
For example, the default result’s $13,140 annual CRSC multiplied by the model’s 22% rate yields $2,891 estimated tax savings after rounding. This is not a guaranteed tax refund or a prediction that your tax bill will fall by exactly that amount. The actual comparison depends on how much of your retired pay would otherwise be taxable and on your other income.
A higher VA rating does not necessarily mean the same percentage of retired pay will be restored as CRSC. The model separately considers total VA compensation and compensation at the combat-related rating, then applies a cap. This is a useful simplification for an estimate, but it does not reproduce every official payment rule.
To see how the benefit fits with other retirement income, use a pension income calculator or a pension withdrawal calculator. If you are planning withdrawals from savings, a 401(k) withdrawal calculator and an IRA withdrawal calculator can help model separate account income. For a broader spending plan, use the retirement needs calculator and retirement withdrawal calculator.
