If you paid $1,200 into the Montgomery GI Bill and also served after 9/11, you may have to choose between two education benefits. For most people, the Post-9/11 GI Bill wins. But not for everyone, and the choice is usually permanent. This guide compares both programs using current numbers, walks through real examples, and explains the 2024 Supreme Court decision that changed the rules for veterans with more than one enlistment.
The Short Answer
The Post-9/11 GI Bill usually pays more if you're:
Going to school full-time, in person
Attending a school with high tuition, or in an area with high housing costs
Planning to transfer benefits to a spouse or child
Separated on or after January 1, 2013, and want benefits that never expire
The Montgomery GI Bill Active Duty (MGIB-AD) can pay more if you're:
Going to school only half-time
Taking all your classes online at a low-cost school
Attending a school where your tuition is already covered by a waiver or employer
Doing flight training or certain high-cost non-degree programs
The rest of this post shows why.
How Each Program Pays
The two programs send money in completely different ways.
The Post-9/11 GI Bill pays your tuition directly to the school, then pays you a housing allowance and a book stipend. At the 100% benefit level for the 2026–2027 school year (August 1, 2026, through July 31, 2027):
Tuition: Full in-state tuition at public schools. At private schools, up to $30,908.34 a year.
Housing: The military housing allowance for an E-5 with dependents at your school's ZIP code, for in-person students. Online-only students get up to $1,261 a month.
Books: Up to $1,000 a year.
Your benefit level runs from 50% to 100% depending on how long you served after September 10, 2001, and every payment is multiplied by that percentage.
The old version of this post said Post-9/11 pays tuition "up to the highest public in-state rate in your state." That rule ended in 2011. Today, public schools are covered in full at the 100% level, and private schools have a national cap.
The Montgomery GI Bill Active Duty pays you a flat monthly amount, and you pay the school yourself. From October 1, 2025, through September 30, 2026, the full-time rate is $2,518 a month if you served at least three continuous years, or $2,043 if you served less. Half-time students get half. The rate adjusts every October 1.
If you paid into the $600 buy-up program while serving, you get up to $150 more a month. Some service members also earned a "kicker," or college fund, that adds more.
Side by Side
| Feature | Post-9/11 GI Bill | Montgomery GI Bill Active Duty |
|---|---|---|
| Who it pays | School (tuition) and you (housing, books) | You |
| Full-time amount | Tuition + local housing rate + books | $2,518/month (3+ years served) |
| Online-only | Tuition + up to $1,261/month housing | Same flat rate as in person |
| Half-time | Tuition and books, but no housing | Half the monthly rate |
| Months of benefits | 36 | 36 |
| Time limit | None if you separated on or after Jan. 1, 2013 | 10 years after separation |
| Transfer to family | Yes, if approved while serving | No |
| Pays during breaks | No | No |
When Post-9/11 Wins
Full-time, in-person school in most places. The housing allowance alone often beats the entire Montgomery payment in medium- and high-cost areas, and Post-9/11 pays your tuition on top of that.
Expensive schools. Montgomery pays the same flat amount at a $4,000-a-year community college as at a $40,000 private university. Post-9/11 covers tuition up to the cap, and the Yellow Ribbon Program can help pay above it at participating schools if you're at the 100% level.
Family. Only the Post-9/11 GI Bill can be transferred to a spouse or child. You must be approved while you're still serving. Under current Defense Department policy, you generally need at least six years of service, and no more than 16, when you apply, and you must agree to serve four more years.
Time. If you separated on or after January 1, 2013, your Post-9/11 GI Bill doesn't expire. Montgomery gives you 10 years. If you think school might be several years off, that matters.
When Montgomery Can Win
These examples use made-up numbers to show how the math works. Plug in your own school's tuition and your own housing rate.
Example 1: Half-time student. Say you work full-time and take two classes a term. Under Post-9/11, you must be enrolled more than half-time to get any housing allowance, so at exactly half-time you'd get tuition and books but $0 for housing. Under Montgomery, you'd get $1,259 a month, half the full-time rate. If your tuition is low, Montgomery puts more money in your pocket.
Example 2: Online at a low-cost school. Say you're full-time and fully online at a public school charging $3,600 a term, about $900 a month over a four-month term.
Post-9/11: Tuition paid, plus up to $1,261 a month in housing and about $83 a month in books. That's roughly $1,344 a month to you.
Montgomery: $2,518 a month, minus about $900 a month for tuition, leaves roughly $1,618 a month to you.
In that case, Montgomery comes out ahead by close to $275 a month. Add one in-person class that counts toward your degree, and Post-9/11 switches to your school's local housing rate. In most places, that flips the math back.
Example 3: Tuition already covered. If a state tuition waiver or your employer already pays your tuition, Post-9/11's biggest advantage disappears. Aid that's set aside only for tuition reduces what the VA pays. Montgomery's flat payment still comes to you in full.
Flight training and some non-degree programs. Montgomery pays 60% of approved flight training costs. Post-9/11 caps flight school at $17,661.89 a year. For expensive flight programs, compare both carefully.
The old version of this post said you could "pocket the difference" with Montgomery at cheap schools. That's true, but only if the difference is bigger than what Post-9/11's housing allowance would have paid you. Run the numbers.
The Choice Is Usually Permanent
If you qualify for both programs from the same period of service, you have to pick one. Once you choose Post-9/11 and give up Montgomery, you can't switch back.
There's another catch. If you've already used some Montgomery months before switching, you only get as many Post-9/11 months as you had left in Montgomery. Use 10 months of Montgomery, switch, and you'll have 26 months of Post-9/11, not 36.
About your $1,200. If you switch to Post-9/11 and use up every month, the VA refunds part or all of your $1,200 Montgomery contribution with your last housing payment. The amount depends on how many Montgomery months you had left when you switched. You must be receiving a housing allowance on the day your benefits run out. The $600 buy-up is never refunded. If a family member uses up your transferred benefits instead of you, you don't get the refund.
If You Have More Than One Enlistment: The Rudisill Rule
In April 2024, the Supreme Court decided Rudisill v. McDonough. For some veterans, it changed "pick one" into "use both."
Here's the short version. If you earned the Montgomery GI Bill in one period of service and the Post-9/11 GI Bill in a separate period, you may be able to use both, for up to 48 months total instead of 36. That's up to a full extra year of school.
A few details matter:
It takes separate periods of service. VA counts a reenlistment as a separate period, but not an extension.
VA generally requires at least 56 months of active duty to qualify for the full 48 months. If you served less, you can generally use only one benefit.
It applies even if you gave up Montgomery in the past. You may be able to get some of that entitlement back.
VA says it reviews these cases automatically. If you think you qualify and haven't heard anything, ask.
Not legal advice: I'm not an attorney or a VSO. Rudisill eligibility depends on your exact service dates and past benefit elections. An accredited VSO can review your records for free before you make an irrevocable choice.
Guard and Reserve Members
The Montgomery GI Bill Selected Reserve (MGIB-SR) is a separate program for drilling Guard and Reserve members with a six-year commitment. It pays $493 a month for full-time school through September 30, 2026. The benefit generally ends when you leave the Selected Reserve.
If you've served on qualifying federal active-duty orders, like a mobilization or deployment, you may also have earned some Post-9/11 GI Bill. Check your percentage before you assume MGIB-SR is all you have.
What About Going Abroad?
The old version of this post said international programs are "generally only available through the Post-9/11 GI Bill." Both programs can pay at VA-approved foreign schools. Post-9/11 caps foreign tuition at the same $30,908.34 as private schools. Housing abroad is paid at the national average rate. Check the school's approval status in the VA's GI Bill Comparison Tool before you apply.
A Few Things That Are the Same
Both pay only while you're enrolled. Neither pays during breaks between terms.
Both use 36 months per benefit. Part-time students use months more slowly under either program.
Both require an honorable discharge in most cases.
Both require monthly enrollment verification for most students. Miss it and payments stop.
Both can cover apprenticeships and on-the-job training, but the payment rules differ, so compare before you start.
Neither program is taxable in most cases.
How to Decide
Price out both programs at your actual school. Use the GI Bill Comparison Tool for Post-9/11. For Montgomery, subtract your tuition from the monthly rate.
Be honest about how you'll study. Full-time, part-time, online, or in person makes a bigger difference than most people expect.
Think about family. If you're still serving and might transfer benefits, only Post-9/11 does that.
Check for Rudisill. If you had more than one enlistment, you may not have to choose at all.
Talk to someone before you sign. Your school certifying official, a VSO, or the GI Bill hotline at 888-442-4551 can review your situation. Don't make the switch on a guess.
Conclusion
Choosing between the Post 9/11 GI Bill and Montgomery GI Bill is about maximizing the value of your military service for years to come. The Post 9/11 GI Bill typically offers greater financial value, especially if you're attending expensive schools or living in high-cost areas. However, the Montgomery GI Bill's flexibility might better suit your specific circumstances. For most veterans, the Post-9/11 GI Bill is the stronger choice. But "most" isn't "all," and the decision is hard to undo. A half hour with a calculator can be worth thousands of dollars.
