CRDP Calculator: Estimate Concurrent Retirement and Disability Pay
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.
Created by Luis Gonzalez · Last updated August 8, 2026
Concurrent Retirement and Disability Pay (CRDP) is a program that can restore some or all military retired pay offset by VA disability compensation for eligible retirees. This calculator estimates the monthly restoration, annual benefit, and total monthly income using your retired pay, VA compensation, disability rating, and years of service.
The default example shows a $1,386 monthly CRDP gain and $16,632 annually. It assumes a 60% VA disability rating, 22 years of service, $2,500 monthly retired pay, and $1,386 monthly VA compensation, with no dependents. The result is an estimate, not an eligibility determination or a DFAS payment calculation. Review the VA’s CRDP eligibility and payment information and confirm your circumstances with the responsible agency.
What the inputs and results represent
Enter gross monthly military retired pay, your VA disability rating, and your monthly VA compensation. Add years of service and dependents if applicable. The calculator uses the entered compensation amount and adds a modeled dependent amount for eligible ratings when dependents are entered. Because VA compensation rates depend on rating, dependents, and current rate tables, use the amount that applies to your own award rather than relying on a generic figure.
The results distinguish between income before and after restoration:
- Monthly CRDP Gain is the modeled amount of retired pay restored after the VA offset.
- Annual Benefit is the monthly gain multiplied by 12.
- Full Retired Pay shows the monthly retired-pay amount entered.
- Total Monthly Income combines retired pay and VA compensation after the modeled restoration.
In the default example, the VA offset is the smaller of $2,500 retired pay and $1,386 VA compensation, so the offset is $1,386. Before CRDP, net retired pay is $2,500 − $1,386 = $1,114. Add $1,386 in VA compensation and total monthly income before restoration is $2,500. The calculator marks the default inputs eligible, restores the $1,386 offset, and estimates total income of $2,500 + $1,386 = $3,886 per month.
This result does not mean CRDP creates a second VA payment. It models restoration of retired pay that was previously offset. The VA compensation is included once in the total.
Eligibility: useful screening, not a ruling
The calculator’s simplified eligibility test requires a disability rating that rounds to at least 50% and at least 20 years of service. It rounds the rating to the nearest 10 percentage points before applying the threshold. Those internal rules help explain the calculator’s result, but actual eligibility can depend on the type of retirement and individual service history.
The Department of Defense and VA describe CRDP eligibility categories and requirements in official guidance. For example, the program generally covers certain regular retirees with qualifying service and a VA disability rating of at least 50%; other retirement categories can have additional requirements. Read the current VA CRDP explanation and check the Defense Finance and Accounting Service CRDP information. Do not treat the calculator’s two-input screening rule as proof of eligibility.
The calculator does not determine eligibility under every special or disability-retirement rule. Years of service alone may not capture the service credit, retirement category, or other facts used in an official decision. If your situation involves a medical retirement, reserve retirement, combat-related disability, or a correction to your service record, confirm how the program applies before budgeting the estimated amount.
CRDP also differs from Combat-Related Special Compensation (CRSC). Eligible retirees generally cannot receive both at the same time; an eligible person may need to compare the programs and make or confirm an election. CRSC has different eligibility rules and tax treatment. Ask DFAS or the relevant service branch how a choice affects your payments. The calculator does not compare CRDP with CRSC.
Default calculation, step by step
The calculator’s default inputs are $2,500 monthly retired pay, 60% VA disability, $1,386 monthly VA compensation, 22 years of service, and zero dependents.
- Check the modeled eligibility conditions. A 60% rating is at least 50%, and 22 years is at least 20 years, so the calculator returns eligible.
- Calculate the VA offset. The smaller of retired pay and adjusted VA compensation is min($2,500, $1,386) = $1,386.
- Find net retired pay before CRDP. $2,500 − $1,386 = $1,114.
- Find total income before CRDP. $1,114 + $1,386 = $2,500 per month.
- Restore the offset under the modeled eligibility test. CRDP gain = $1,386 per month.
- Annualize the gain. $1,386 × 12 = $16,632 per year.
- Estimate total income after restoration. $2,500 retired pay + $1,386 VA compensation = $3,886 per month.
These values are rounded to whole dollars in the result cards. The calculation does not model a payment-start date, phase-in schedule, retroactive payment, debt collection, or every DFAS adjustment.
Formula: offset, restoration, and annual gain
Adjusted VA compensation =
entered monthly VA compensation + modeled dependent add-on
VA offset =
smaller of monthly retired pay or adjusted VA compensation
CRDP gain =
VA offset, if the calculator's eligibility test is met;
otherwise 0
Annual CRDP gain = monthly CRDP gain × 12
The calculator estimates total income before restoration as net retired pay plus adjusted VA compensation. If eligible under its simplified rule, it estimates post-restoration income as full retired pay plus adjusted VA compensation.
Tax treatment and what the estimate leaves out
CRDP restores military retired pay; it is generally treated as taxable retired pay, while VA disability compensation is generally not taxable as federal income. The exact tax result depends on your situation and other income. The calculator’s tax bracket input does not appear in its computation, so it does not estimate after-tax CRDP income. Do not subtract the entered bracket from the result or interpret the displayed total as take-home pay.
For general federal rules, the IRS explains the tax treatment of military retirement pay and VA benefits in its tax information for members of the Armed Forces. State tax rules may differ. A pension income calculator can help model other retirement income, while a military retirement calculator can estimate retired pay from service and pay inputs.
The tool also does not calculate VA disability compensation from the rating, determine dependents’ eligibility, apply individual VA rate tables, or account for every deduction or payment adjustment. Use the amount on your current award information and compare the estimate with official payment records.
Compare income scenarios
Each row below changes one input from the default. The outputs shown are arithmetic consequences of the calculator’s stated rules, not official determinations.
| Scenario | Changed input | Modeled monthly CRDP gain | Modeled total monthly income |
|---|---|---|---|
| Lower VA compensation | VA compensation: $1,000 | $1,000 | $3,500 |
| Lower retired pay | Retired pay: $1,000 | $1,000 | $2,386 |
| Rating below threshold | Rating: 40% | $0 | $2,500 |
In the first scenario, the offset is min($2,500, $1,000) = $1,000, and the calculator’s eligibility conditions remain met. Total income after restoration is $2,500 + $1,000 = $3,500.
In the second, the offset is min($1,000, $1,386) = $1,000. The modeled gain is $1,000, and post-restoration income is $1,000 + $1,386 = $2,386. In the third, a 40% rating fails the calculator’s 50% threshold, so it restores $0 and leaves the modeled total at $2,500. Actual eligibility may differ from this simplified screening result.
If you are planning a full retirement budget, compare military income with Social Security, savings withdrawals, and other benefits. You can use the retirement annuity calculator or pension withdrawal calculator for additional income scenarios. A retirement withdrawal calculator can help assess the amount your portfolio may need to provide.
Frequently asked questions
Does CRDP restore all of my VA offset?
Not necessarily. The calculator restores the full modeled offset only when its eligibility test is met. Actual program rules and individual circumstances determine the amount and payment treatment; verify with VA or DFAS.
Is CRDP the same as receiving both full retired pay and VA compensation?
CRDP can restore retired pay that was offset by VA compensation for eligible retirees. In the calculator’s eligible scenario, the estimated total is full retired pay plus VA compensation. It is not a second VA award.
Is the calculator’s result after tax?
No. It is a gross monthly estimate. The tax-bracket input is not used in the calculation, and the tool does not estimate withholding or take-home income.
Why does the calculator use a 50% disability threshold and 20 years of service?
Those are the simplified eligibility conditions coded into this estimate. Official CRDP eligibility can depend on retirement category and additional rules, so the calculator’s screen is not an official determination.
Should I choose CRDP or CRSC?
That depends on eligibility, amount, tax treatment, and personal circumstances. The programs have different rules, and eligible retirees generally cannot receive both at the same time. Compare official estimates and ask DFAS or your service branch before making an election.
Does adding dependents automatically give the correct VA amount?
No. The calculator applies a modeled dependent add-on based on its rating table and dependent count. VA compensation depends on the applicable rate schedule and qualifying dependent details. Use your current award amount and verify changes with VA.
What should I do if my official payment differs?
Check the VA award amount, retirement category, service history, deductions, and DFAS payment statement. If the difference remains unexplained, contact the agency responsible for the specific payment rather than adjusting the calculator to force a match.
Use this estimate to prepare questions and a budget; use VA and DFAS records to confirm eligibility and payment amounts.
