Should I use the Montgomery GI Bill or Post-9/11 GI Bill for a fully online degree program?

The Montgomery GI Bill (MGIB, Chapter 30) and the Post-9/11 GI Bill (Chapter 33) work very differently, and the better choice depends on your specific entitlement history and how the program is delivered.

Under MGIB, the VA pays you a fixed monthly benefit directly, and you are responsible for paying tuition, fees, and any other costs to the school yourself. The amount is the same regardless of your tuition cost and does not include a separate housing allowance.

Under the Post-9/11 GI Bill, the VA pays tuition and fees directly to the school (subject to a cap for private and out-of-state schools, which can affect you at a private institution like Purdue Global), plus you may receive a monthly housing allowance (MHA) and a yearly book stipend. For programs that are entirely online with no in-person component, the MHA is paid at half the national average BAH rate rather than a location-based rate — this is a meaningful difference from in-person or hybrid programs, where the allowance is tied to the school's zip code.

You generally cannot use both benefits for the same period of enrollment, and in many cases choosing Post-9/11 GI Bill after having MGIB eligibility requires an irrevocable one-time election, so compare total remaining months of entitlement and projected payout before deciding. The GI Bill Comparison Tool on va.gov lets you enter the specific school and program to see estimated tuition coverage and housing rates under each benefit.

Your 100 percent disability rating does not by itself change which GI Bill benefit to choose, but it may make you eligible to explore Chapter 31 Veteran Readiness and Employment (VR&E) benefits instead of or alongside GI Bill benefits, since a serious service-connected disability is one of the threshold factors VA considers for that program. VR&E has its own eligibility determination process and is not interchangeable with Chapter 30 or Chapter 33.

Because the right answer depends on how much entitlement you have left under each program and whether you've already made an irrevocable election, the concrete next step is to log into va.gov to check your remaining MGIB and Post-9/11 entitlement months, run the specific Purdue Global online program through the GI Bill Comparison Tool, and call the VA Education Call Center to confirm which program maximizes your benefit before enrolling.
