Post-9/11 GI Bill vs. Montgomery GI Bill (MGIB): Key Differences and Eligibility Breakdown

Post-9/11 vs. Montgomery GI Bill

Veterans and current service members are offered education benefits under several GI Bill® programs. Among the various programs, two of the most compared and applied for GI Bill® Veteran’s Education Benefits Program are the Montgomery GI Bill® (MGIB) and the Post‑9/11 GI Bill® (Chapter 33). The Montgomery GI Bill predates Post‑9/11, and it was the main GI Bill® educational benefit for many years. The Post‑9/11 GI Bill®, launched in 2008 (effective August 1, 2009), was designed to expand and modernize the benefits for those who served after September 10, 2001.

While both programs provide up to 36 months of benefits, the differences in eligibility, the amount paid, and how benefits are delivered are significant. The program you choose depends on your eligibility, service record, your educational goals, whether you need housing support, and whether you plan to transfer benefits to dependents.

GI Bill® Education Benefits: Post-9/11 vs. Pre-9/11 (Montgomery) Programs

Montgomery GI Bill®

The Montgomery GI Bill®, also known as the Pre-9/11 GI Bill®, is a U.S. Department of Veterans Affairs education benefit program that provides a monthly stipend to eligible Active-duty Service Members (MGIB-AD) and Selected Reserve (MGIB-SR) to cover education and training costs. Depending on service dates and contracts, it broadly applies to service members who served before or after 9/11.

The program requires veterans and service members to pay $1,200 during their first year of service. It later offers them up to 36 months of benefits for use at approved institutions or training programs

The Post‑9/11 GI Bill® (Chapter 33)

The Post‑9/11 GI Bill® (Chapter 33) is another education benefit program for veterans who served active duty after September 10, 2001. It covers up to 100% of tuition fees, provides a monthly housing allowance, and includes a stipend for books and supplies, making it ideal for those attending college, vocational training, or other approved programs.

What Are the Key Eligibility Differences

Criterion Montgomery GI Bill® (MGIB) The Post-9/11 GI Bill®
Service requirement Typically, at least 2–3 years of active duty, depending on contract; or for Selected Reserve, certain service obligations. At least 90 days aggregate active-duty service after Sept 10, 2001, for full benefits, 36 months or more. Also, special provisions for 30 days and discharge for disability.
Honorable discharge or status Required. Required.
Time to use benefits after separation Usually 10 years. Originally 15 years, but under the Forever GI Bill® legislation, for many, the 15-year limit has been removed for service on or after Jan 1, 2013.

What the Benefits Look Like

Here are the benefits covered under the two programs, and how they differ:

Benefit Type Montgomery GI Bill® (MGIB) The Post-9/11 GI Bill®
Tuition & Fees MGIB gives a fixed monthly stipend directly to the veteran. The veteran is responsible for paying the school. The stipend is based on service, what kind of program, etc. Tuition and fees are paid directly to the school. If the veteran is attending a public in-state school, a full tuition fee may be covered. For private or non-public schools, there is a cap on the tuition fee.
Housing / Living Expenses MGIB does not provide a separate housing allowance. Veterans may have to use their monthly stipend if living expenses need to be covered. Post-9/11 GI Bill® provides a Monthly Housing Allowance (MHA), based on the Basic Allowance for Housing (BAH) of an E-5 with dependents in the location of the school (if attending in-person, more than half-time). For online or distance classes, there is usually a reduced or no housing benefit.
Books & Supplies MGIB does not provide a separate books and supplies fee; veterans must cover these from their monthly stipend. Post-9/11 GI Bill® offers up to $1,000/year for books, supplies, etc.
Transfer to Dependent MGIB benefits are not transferable to dependents. Under the Post-9/11 GI Bill®, transfer of unused benefits to spouse or children is possible under certain criteria (e.g., must be serving long enough, must elect transfer while still active duty, and meet other requirements).
Duration or Usage Window for Benefits Up to 36 months of benefits. For MGIB, benefits generally must be used within 10 years after discharge or separation (for those eligible) under the traditional rules. Up to 36 months of benefits. For many, under the Post-9/11 GI Bill®, one has 15 years after separation; recent legislation, Forever GI Bill®, has removed the time limit for certain categories (for example, service members who served after Jan 1, 2013).
Eligibility for Training Types MGIB may cover a wide variety: degree programs, non-degree (vocational, technical), apprenticeships, correspondence courses, licensing/certification, etc. Post-9/11 GI Bill® is applicable for approved degree-granting institutions, but for some non-degree or non-traditional programs (trade, certification, etc.), eligibility depends on whether the institution is approved, or whether the veteran transferred in from MGIB or another similar program. In some cases, non-degree programs might have fewer benefits or different rules.

Which Program Might Work for You, Depending on the Situation

Scenario Likely Better Choice
Full-time degree at a public in-state college Post-9/11 GI Bill® may likely work for you because you typically get full coverage of tuition, housing, and books.
Private or out-of-state college with high tuition Post-9/11 GI Bill® may still be better, especially if Yellow Ribbon covers the excess, but compare carefully, if tuition is enormously above cap.
Less than half-time or online study Might favor MGIB or compare carefully. Post-9/11 GI Bill® housing and stipend benefits are often reduced or eliminated.
Want to transfer benefits to spouse/children Post-9/11 GI Bill®, since MGIB doesn’t offer this.
Want maximum flexibility and maximum benefit (especially living costs) Post-9/11 GI Bill®, almost always wins here.

If eligible for both Post‑9/11 GI Bill® and Montgomery GI Bill®, it is essential to compare your cost of tuition fees, living expenses, and books under your intended institution to pick the best for you. Also, review the rules for eligibility, service time, election, and deadlines. Some rules change based on date of entry, active duty, etc.

It is also important to note that if you are eligible for both programs, choosing the Post‑9/11 GI Bill®, generally means you forgo your MGIB for that same benefit period. The election is often irreversible.

Conclusion

Both the Post-9/11 GI Bill® and the Montgomery GI Bill® offer valuable educational benefits to different service members and veterans coming from different service backgrounds. Understanding the difference between the different education benefit programs and evaluating your individual eligibility, educational goals, and financial needs is key to selecting the program that best supports your path to success.

Suppose you are a veteran or service member eligible for both. In that case, it would be wise to run the numbers using your likely institution’s tuition, housing, expenses, and the type of program you will enroll in, part‑time or full-time, and see which gives you more for your educational costs.

Speak to a VA Enrollment Advisor from the institute where you plan to pursue your education. For example, EC-Council University is approved to accept VA education benefits for the ECCU program. A dedicated team of Veterans’ Enrollment Advisors will guide you through your enrollment process and navigate through the different VA education benefits programs.

FAQs

You can’t use both concurrently. You generally choose which GI Bill® you want to use. But suppose you have separate qualifying periods of service. In that case, one qualifying for MGIB and for Post‑9/11 GI Bill®, under the Rudisill decision, you may be eligible for up to 48 months total by combining entitlements.

No, once you select to use Post‑9/11 GI Bill®, you usually give up the ability to use MGIB (for that same entitlement period).

You may be eligible for additional benefit months (up to 48 in total). Also, some MGIB entitlements you relinquished when choosing Post‑9/11 GI Bill® may be reinstated.

For Post‑9/11 GI Bill®, if your last separation from active duty was before January 1, 2013, your benefits expire 15 years after that separation. If on or after January 1, 2013, there is no expiration under the Forever GI Bill® law.
For Montgomery, there are earlier time limits (often 10 years) in many cases. (Check your specific contract and discharge date.)

It depends on the length of active-duty service after September 10, 2001. For example, 36 months or certain conditions yield 100%; less time yields lesser percentages (e.g. 90%, 80%, etc.). The VA publishes the qualifying time thresholds.
