Education Benefits
What the GI Bill actually pays for, how your active-duty time sets your percentage, and how to read the three parts of the benefit before you ever pick a school.

It pays three things, and they are calculated separately. That is the part most service members miss.
1. Tuition and fees. At a public school in your state, the VA covers your full in-state tuition and required fees at the 100% level. At a private or foreign school, payment is capped at a national maximum that the VA resets every August.
2. Monthly housing allowance (MHA). The MHA is a monthly check for your living costs. If you are in school more than half-time, you get one based on where your school sits, not where you live. More on the active-duty catch below.
3. Books and supplies. Up to $1,000 per academic year, paid at the start of each term and split up by how many credits you carry.
You have up to 36 months of entitlement, which is the number of months of benefit you have to spend. That lines up with a standard four-year degree at full-time enrollment. If you qualify for both the Post-9/11 and the Montgomery GI Bill through separate periods of service, a 2024 Supreme Court decision (Rudisill) can stretch your combined cap to 48 months.
The Post-9/11 GI Bill is three benefits that pay on their own, and your active-duty time sets one percentage that scales all of them.
What sets your amount
Your percentage: Your active-duty time sets your percentage (50% to 100%), and that percentage scales all three. 90+ days qualifies; a Purple Heart or a service-connected disability discharge goes straight to 100%.

You qualify with at least 90 days of active-duty service on or after September 11, 2001. Two other paths get you straight to 100%: a Purple Heart on or after 9/11/2001 with an honorable discharge, or at least 30 straight days of active duty followed by a discharge for a service-connected disability.
Past those shortcuts, your percentage tracks your total active-duty days. Each reenlistment counts as a separate period of service, so deployment and mobilization time adds up.
Your percentage scales everything: tuition, housing, and books all pay at that rate.
Here is the current-year math for the academic year that runs August 1, 2025 through July 31, 2026, shown at the 100% level. Multiply by your percentage for anything less. At 100%, the benefit covers full in-state public tuition with no cap, up to $29,920.95 a year at private or foreign schools, a housing allowance tied to your school's location (up to $1,169 a month if you study fully online), and up to $1,000 a year for books.
This is the piece that trips up service members who start a degree while still in uniform. If you use the Post-9/11 GI Bill on your own behalf while you are on active duty, you do not draw the monthly housing allowance. You are already getting housing through the barracks or your BAH, so the VA does not stack a second housing payment on top.
Two practical points fall out of that. First, the housing allowance is often the most valuable part of the benefit, and it tends to be worth more after you separate, when you can collect it. Second, the MHA pays the BAH rate for an E-5 with dependents at your school's ZIP code, so a campus in San Diego pays far more than one in rural Georgia, no matter your actual rank.
The VA also does not pay MHA during school breaks between terms, and it splits up the first and last month of each term. Plan your cash flow around the gaps, the same way you would plan around a late LES.
The housing allowance is often the biggest piece of the benefit, but using the GI Bill while you are still serving can leave it on the table. Here is what to weigh before you commit.
The catch: Use the GI Bill on your own behalf while on active duty and you do NOT draw the monthly housing allowance. You already get housing, so the VA does not stack a second payment.
Worth knowing

You can start using the benefit after 90 days of qualifying service, including while you are still serving. The expiration depends on your discharge date. If you left active duty before January 1, 2013, you have 15 years to use it. If your service ended on or after January 1, 2013, the Forever GI Bill removed the clock and the benefit does not expire.
One more fork worth knowing early: you generally pick one benefit per period of service. If you choose the Post-9/11 GI Bill, you give up the right to switch back to the Montgomery GI Bill for that period, and the reverse holds too. Talk to your education office before you lock it in.
How does the Post-9/11 GI Bill work?
It pays tuition and fees, a monthly housing allowance, and a books stipend as three separate amounts. Your service time sets the percentage you receive, up to 36 months of benefit.
How much does the GI Bill pay?
At 100%, it covers full in-state public tuition with no cap, up to $29,920.95 per year at private or foreign schools, a housing allowance tied to your school's location (up to $1,169 per month if you study fully online), and up to $1,000 a year for books, for the 2025 to 2026 year.
Can I use the GI Bill while I am still active duty?
Yes, after 90 days of qualifying service. The catch is that you do not collect the monthly housing allowance while you are on active duty, since the military already provides your housing.
Does the GI Bill pay housing if I take classes online?
Yes, if you are enrolled more than half-time. Fully online students get a flat rate, up to $1,169 per month for 2025 to 2026, which is half the national average. In-person students get the E-5 with-dependents BAH rate for the school's ZIP code.
How many months of GI Bill do I get?
Up to 36 months. If you qualify for two separate GI Bill programs through different periods of active duty, the Rudisill decision can raise your combined cap to 48 months.
Does my GI Bill expire?
For most people now, no. If your active duty ended on or after January 1, 2013, it does not expire. If it ended before that date, you have 15 years from your last separation to use it.
What is the difference between the Post-9/11 and the Montgomery GI Bill?
The Post-9/11 GI Bill pays tuition to the school plus a housing allowance and book stipend. The Montgomery GI Bill pays you one flat monthly amount and you cover your own tuition from it. You usually choose one per period of service, and the choice is hard to undo, so check with your education office first.
Your installation Education Services Officer (ESO) or Army Education Center is free, in person, and reads these rules for a living. You can also reach the VA Education Call Center at 888-442-4551 (Monday to Friday, 8:00 a.m. to 7:00 p.m. ET). Your school's certifying official (SCO) in the registrar or veterans office is the person who actually files your enrollment with the VA. The VA Post-9/11 GI Bill overview and the GI Bill Comparison Tool, both linked in Sources, are worth a read before you pick a school.
