CRDP vs CRSC Calculator
Military retirees with VA disability can receive both retirement pay and VA compensation — but CRDP and CRSC restore that money in different ways. One is taxable, one isn't. The right choice can mean thousands of dollars a year.
The VA Offset Problem
For decades, a federal law created a cruel double-billing for disabled military retirees. Both retirement pay and VA disability compensation come from the federal government — and Congress decided you couldn't collect both in full. For every dollar in VA compensation you received, your retirement pay was reduced by one dollar. You got the same total amount as if you only had one benefit.
This made no logical sense: VA compensation replaces income lost due to disability. Retirement pay is compensation for years of service. They are different things. Congress eventually agreed — and created two separate programs to fix the problem.
CRDP and CRSC both eliminate this offset — but they do it differently, they have different eligibility requirements, and one is taxable while the other is not. You can only use one at a time.
CRDP — Concurrent Retirement and Disability Pay
CRDP simply restores the VA offset. If you qualify, DFAS pays you back the retirement pay that was previously withheld to offset your VA compensation — so you receive your full retirement pay AND your full VA compensation simultaneously.
CRSC — Combat-Related Special Compensation
CRSC pays a tax-free monthly amount equal to the VA compensation you receive for combat-related disabilities, up to your gross retirement pay. Because it's tax-free, it is often the higher net-income option — even when the gross CRDP amount looks larger.

The January Election Window
If you qualify for both CRDP and CRSC, you elect one each January. DFAS sends you a comparison letter. You are not locked in forever — you can switch programs each year during the open election period.
This means your optimal choice can change over time. If your VA rating increases, the CRSC/CRDP math shifts. If tax law changes, it shifts again. Check your numbers every year when DFAS sends your annual notice.
Chapter 61 Medical Retirees — Different Rules
Chapter 61 retirees — those separated for disability before completing 20 years — have more complex CRDP eligibility. CRDP requires that your disability rating equals your percentage of disability for retirement purposes, and the VA rating must be 50% or higher.
CRSC is available to Chapter 61 retirees with combat-related disabilities at any rating, making it especially important for those medically retired before reaching 20 years. If you are a Chapter 61 retiree, the calculator below is directional — consult your VSO for the exact rules that apply to your case.
