The standard advice is right 90% of the time: the Post-9/11 GI Bill is better than the Montgomery GI Bill for most veterans. The Post-9/11 pays tuition directly to the school plus a housing allowance based on the school's ZIP code. For most people attending a typical university, this produces more total value.
But there are three specific situations where the Montgomery GI Bill (MGIB, Chapter 30) actually puts more money in your pocket. If any of these describe you, do the math before switching.
How MGIB Works (The Basics)
The Montgomery GI Bill pays a flat monthly rate directly to you — currently $2,185.20/month for full-time enrollment. It doesn't pay the school separately. You receive the check and pay tuition yourself. If your tuition is lower than the monthly payment, you keep the difference. If your tuition is higher, you pay the gap.
If you made the optional $600 buy-up contribution during service, add $150/month to the rate ($2,335.20/month total). Over 36 months, that $600 investment returns $5,400 — one of the best guaranteed returns available to service members.
When MGIB Wins
Scenario 1: Very cheap school + low-cost area. If you attend a community college or affordable state school where tuition is $3,000-$5,000/year, and you live in a low-BAH area where the Post-9/11 housing rate is $1,200-$1,500/month, MGIB's flat $2,185/month can net you more cash. You'd pay tuition out of the MGIB payment and keep the rest. Run the numbers for your specific school and location.
Scenario 2: Online-only student. The Post-9/11 GI Bill pays online-only students just $1,054.50/month in housing, and pays tuition separately. If you're attending a cheap online program where tuition is low, MGIB's $2,185/month flat payment exceeds the Post-9/11's combined tuition + online housing rate. This is the most common scenario where MGIB wins.
Scenario 3: Employer/scholarship covers tuition. If you have a full-ride scholarship, employer tuition reimbursement, or tuition waiver, the Post-9/11's tuition payment to the school is partially or fully wasted — you'd receive the housing allowance only. MGIB's full $2,185/month goes to you regardless, since it doesn't pay the school. If your BAH rate would be under $2,185 and your tuition is already covered, MGIB wins.
When Post-9/11 Always Wins
If you attend any school in a metro area where BAH exceeds $2,200/month (most mid-to-large cities), Post-9/11 wins because the housing allowance alone exceeds MGIB's total flat rate — and you get tuition paid separately on top. If your tuition exceeds $5,000-$6,000/year, Post-9/11 almost certainly wins because the direct tuition payment adds significant value.
For the majority of veterans — attending a 4-year university, in-person, in a typical metro area — Post-9/11 produces $50,000-$150,000+ more in total value than MGIB. The edge cases above are real but uncommon.
Switching: Irrevocable Decision
You can switch from MGIB to Post-9/11 GI Bill, but the election is irrevocable — you cannot switch back. You can also use MGIB for some semesters and then elect Post-9/11 for remaining months (total cannot exceed 36 months). Some veterans strategically use MGIB for a cheap online program, then switch to Post-9/11 when they transfer to an in-person school in a high-BAH area.
If you have a VA disability rating of 10%+, consider VR&E (Chapter 31) instead of either GI Bill — it provides 48 months, no tuition cap, and the same housing rate as Post-9/11, making it objectively better than both for eligible veterans.
