The Montgomery GI Bill (MGIB) comes in two versions. MGIB-Active Duty (MGIB-AD, Chapter 30) is for people with qualifying active duty, and MGIB-Selected Reserve (MGIB-SR, Chapter 1606) is for Selected Reserve members with a 6-year service obligation. In the MGIB active duty vs MGIB selected reserve comparison, MGIB-AD pays $2,601.00 a month for full-time study at the 3-year rate, and MGIB-SR pays $508.00. MGIB-AD usually costs the member a $1,200 pay reduction, while MGIB-SR has no pay reduction but generally ends when you leave the Selected Reserve.
Both monthly figures are full-month rates published by the Department of Veterans Affairs (VA) for October 1, 2026 to September 30, 2027. The VA resets these rates every October 1.
MGIB-Active Duty (Chapter 30) vs MGIB-Selected Reserve (Chapter 1606): Side-by-Side Comparison
| Factor | MGIB-Active Duty (Chapter 30) | MGIB-Selected Reserve (Chapter 1606) |
|---|---|---|
| Who it covers | Veterans and service members with qualifying active duty and an honorable discharge | Selected Reserve members with a 6-year service obligation in good standing in an active unit |
| Cost to the member | $100 a month for the first 12 months ($1,200 total) under Category I | No pay reduction |
| Full-time monthly rate (Oct 1, 2026 to Sep 30, 2027) | $2,601.00 (3-year rate) or $2,110.00 (2-year rate) | $508.00 |
| Half-time monthly rate | $1,300.50 (3-year rate) or $1,055.00 (2-year rate) | $253.00 |
| Maximum months | Up to 48, but many applicants are eligible for only 36 | Up to 36 |
| When eligibility ends | You usually have 10 years to use it | Usually the day you leave the Selected Reserve |
| Education requirement | High school diploma, General Educational Development (GED) certificate or 12 hours of college credit (Category I) | High school diploma or equivalent before finishing initial active duty for training (IADT) |
| 36-month full-time total (Rank and Pay calculation) | $93,636.00 (36 x $2,601.00) | $18,288.00 (36 x $508.00) |
MGIB Active Duty vs MGIB Selected Reserve at a Glance
MGIB-AD (Chapter 30) is for veterans and service members with qualifying active duty and pays $2,601.00 a month for full-time study at the 3-year rate. MGIB-SR (Chapter 1606) is for Selected Reserve members with a 6-year obligation and pays $508.00 a month full time. The difference is $2,093.00 a month ($2,601.00 minus $508.00).
The comparison table sets the two programs side by side on eligibility, cost to the member, monthly rates, maximum months and when the benefit ends. Both carry the Montgomery GI Bill name, but the VA publishes separate eligibility pages and separate rate tables for each one.
Your type of service decides which program to read about first. Qualifying active duty points to Chapter 30. Service in an active Selected Reserve unit under a 6-year obligation points to Chapter 1606.
Who Qualifies for MGIB-AD
MGIB-AD requires an honorable discharge and at least 2 years on active duty, plus the conditions of one of four eligibility categories on the VA's MGIB-AD eligibility page. Category I covers members who first entered active duty after June 30, 1985, and it has four conditions.
- You have a high school diploma, a General Educational Development (GED) certificate or 12 hours of college credit.
- You first entered active duty after June 30, 1985.
- Your pay was reduced by $100 a month for the first 12 months, a total of $1,200.
- You served continuously for 3 years, or 2 years if that was your enlistment agreement, or 4 years if you entered the Selected Reserve within a year of leaving active duty.
The other three categories cover different service histories. Category II covers service that began before January 1, 1977. Category III requires $1,200 of pay reduced before separation plus one qualifying separation condition.
Category IV gives two ways to pay in: $100 a month for 12 months, or a $1,200 lump-sum contribution. The Rank and Pay Chapter 30 guide notes that the $1,200 reduction is non-refundable. The VA returns MGIB-AD contributions in one case only. If you use the Post-9/11 GI Bill and use up that entitlement, the VA refunds part or all of those contributions, up to $1,200.
Who Qualifies for MGIB-SR
MGIB-SR requires a 6-year service obligation in the Selected Reserve, and it has no pay reduction. The VA's MGIB-SR eligibility page lists four conditions.
- A 6-year service obligation in the Selected Reserve. Officers must agree to serve 6 years beyond their initial obligation.
- Good standing in an active Selected Reserve unit.
- Completion of initial active duty for training (IADT).
- A high school diploma or equivalent before you finish IADT.
Eligibility usually ends the day you leave the Selected Reserve. For a Reservist, that means unused MGIB-SR months usually go away on the separation date. The VA lists three exceptions to that rule.
- You separated because of a disability that was not caused by misconduct.
- Your unit was deactivated between October 1, 2007 and September 30, 2014.
- You were involuntarily separated, for reasons other than misconduct, between October 1, 2007 and September 30, 2014.
If an exception applies, you can qualify for 14 years from the date of your first 6-year obligation. The VA's MGIB-SR page does not mention a kicker (a bonus paid on top of the base rate). The Rank and Pay Chapter 1606 guide covers the program in more depth.
Monthly Rates for MGIB Active Duty vs MGIB Selected Reserve
MGIB-AD pays up to $2,601.00 a month for full-time study. MGIB-SR pays up to $508.00, based on the VA's published rate tables for October 1, 2026 to September 30, 2027. The VA lists MGIB-AD at two levels, a 3-year rate and a 2-year rate, on its MGIB-AD rates page. The figures below apply to colleges and non-college degree programs.
| Enrollment | 3-year rate | 2-year rate |
|---|---|---|
| Full time | $2,601.00 | $2,110.00 |
| 75% | $1,950.75 | $1,582.50 |
| 50% | $1,300.50 | $1,055.00 |
| Less than 50%, more than 25% | $1,300.50 (or tuition and fees if less) | $1,055.00 (or tuition and fees if less) |
| 25% or less | $650.25 (or tuition and fees if less) | $527.50 (or tuition and fees if less) |
MGIB-SR has a single rate table on the VA's MGIB-SR rates page.
| Enrollment | Monthly rate |
|---|---|
| Full time | $508.00 |
| 75% | $408.00 |
| 50% | $253.00 |
| Less than 50% | $127.00 |
MGIB-AD pays more at every enrollment level. At half time, MGIB-AD pays $1,300.50 at the 3-year rate and MGIB-SR pays $253.00, a difference of $1,047.50 a month.
Three rules can lower the amount you receive in a given month.
- All rates are for a full month. Veterans on MGIB-AD and students on MGIB-SR get a prorated share based on the days they are enrolled.
- Members on active duty who use MGIB-AD get the published rate or their tuition and fees, whichever is less.
- Rates reset every October 1, so the figures in these tables apply only through September 30, 2027.
MGIB-SR payments go directly to the student. The VA's MGIB-AD page lists whether you qualify for a college fund or kicker as one factor in your rate.
36-Month Totals for MGIB-AD vs MGIB-SR
Over 36 months of full-time study, MGIB-AD pays $93,636.00 at the 3-year rate. MGIB-SR pays $18,288.00 over the same 36 months, and both totals come from a Rank and Pay calculation using the VA's October 1, 2026 rates. Each total is the full-time monthly rate multiplied by 36. Rank and Pay uses 36 months for both programs because MGIB-SR tops out at 36 and many MGIB-AD applicants are eligible for only 36.
| Program | Full-time monthly rate (VA) | Months | 36-month total |
|---|---|---|---|
| MGIB-AD, 3-year rate | $2,601.00 | 36 | $93,636.00 |
| MGIB-AD, 2-year rate | $2,110.00 | 36 | $75,960.00 |
| MGIB-SR | $508.00 | 36 | $18,288.00 |
The 3-year MGIB-AD rate is 5.12 times the MGIB-SR rate ($2,601.00 divided by $508.00). At the 2-year rate, the multiple is 4.15 ($2,110.00 divided by $508.00). Over 36 months, the 3-year MGIB-AD total is $75,348.00 higher than the MGIB-SR total ($93,636.00 minus $18,288.00).
The $1,200 MGIB-AD pay reduction equals 0.46 of one month at the 3-year rate ($1,200 divided by $2,601.00). Net of that reduction, the 36-month total at the 3-year rate is $92,436.00 ($93,636.00 minus $1,200).
These totals are full-time ceilings, and several situations pay less.
- Part-time enrollment pays a lower monthly rate in both programs.
- Active-duty members on MGIB-AD get tuition and fees when those cost less than the rate.
- Anyone with fewer than 36 months of entitlement collects fewer payments.
- The totals use the October 1, 2026 rates for all 36 months, while the VA resets rates every October 1.
How Long Each Benefit Lasts
MGIB-AD usually gives you 10 years to use the benefit, and MGIB-SR usually ends the day you leave the Selected Reserve. The two programs also differ on the maximum number of months they pay.
For MGIB-AD, the VA sets a maximum of 48 months, but many applicants are eligible for only 36. The VA says the 10-year limit can change depending on your situation.
For MGIB-SR, the maximum is 36 months. MGIB-SR is tied to your Selected Reserve status, so leaving the Selected Reserve usually ends eligibility that same day.
The MGIB-SR exceptions extend that window. A Reservist who leaves the Selected Reserve without one of the VA's exceptions usually loses any unused MGIB-SR months on the separation date.
Limits on Using More Than One GI Bill
If you served less than 56 months on active duty, the VA says you can generally use only one education benefit. If you served 56 months or more, you may get up to 48 months of benefits in total, including up to 12 additional months.
The Post-9/11 GI Bill is a third program to weigh, and its entitlement is capped at 36 months. The Post-9/11 GI Bill guide covers its rules, and the GI Bill comparison lines up every chapter side by side.
Two VA rules apply to anyone who paid the MGIB-AD reduction and later moved to Post-9/11.
- If you use the Post-9/11 GI Bill and use up that entitlement, the VA refunds part or all of your MGIB-AD contributions, up to $1,200.
- Under the Rudisill decision, some people who gave up MGIB-AD to use Post-9/11 may qualify for some MGIB-AD entitlement, up to 12 added months with two or more qualifying periods. The VA reviews these cases automatically.
The VA's MGIB-AD and MGIB-SR pages do not describe drawing Chapter 30 and Chapter 1606 payments at the same time. If you hold eligibility for both, the one-benefit rule for service under 56 months is the published limit to plan around.
Picking a Montgomery GI Bill Program
MGIB-AD (Chapter 30) pays more for anyone who meets its rules. Those are its active-duty and pay-reduction rules, and it pays $2,601.00 a month full time against $508.00 for MGIB-SR (Chapter 1606). MGIB-SR fits a Selected Reserve member with a 6-year obligation who plans to study while staying in an active unit, and it has no pay reduction.
Each program is a poor fit for some readers.
- A Reservist with no qualifying active duty cannot use MGIB-AD, whatever the size of the rate gap.
- A veteran who has left the Selected Reserve usually cannot use MGIB-SR, unless one of the VA's exceptions applies.
- Anyone who qualifies for the Post-9/11 GI Bill should compare it before using either Montgomery program, because service under 56 months generally allows only one education benefit.
Three changes in your situation or the VA's rates would move this answer. They are a new VA rate table on October 1, a change in your enrollment level between full time, 75% and 50%, or eligibility for the Post-9/11 GI Bill or for both Montgomery programs.
To settle MGIB active duty vs MGIB selected reserve, start from your service record. Open the Chapter 30 guide if your service includes qualifying active duty or the Chapter 1606 guide if you serve in the Selected Reserve, then file through the VA's how to apply page.
Verdict: Which Should You Choose?
Pick MGIB-AD (Chapter 30) if you have qualifying active duty and paid the $1,200 reduction, because it pays $2,601.00 a month full time at the 3-year rate. Pick MGIB-SR (Chapter 1606) if you serve in an active Selected Reserve unit. It fits when you hold a 6-year obligation and plan to use it before you leave the Selected Reserve, at $508.00 a month full time.
MGIB-AD is a poor fit for a Reservist with no qualifying active duty, who cannot use it. MGIB-SR is a poor fit for anyone leaving the Selected Reserve without a VA exception, because eligibility usually ends that day. A new October 1 rate table, a change in enrollment level, or eligibility for the Post-9/11 GI Bill would change the answer.
