The PMR is an amount based on the locality meal rate and the Gov't meal rate (GMR). The per diem tables on this website have the PMRs already computed. The examples below, using the Standard CONUS M&IE rate ($51) and the Standard GMR ($13.85), show how to compute a PMR amount. The Standard CONUS M&IE rate ($51) consists of $46 for meals, and $5 for incidental expenses.
Add the locality meal rate and the GMR
$46 + $13.85 = $59.85
Divide step 1 total in half (rounded-up to the nearest dollar)
$59.85 / 2 = $29.93 ($30)
Add step 2 (the PMR) total to the incidental expense amount
$30 + $5 = $35
Proportional M&IE rate is step 3 total

The computation rules in these regulations may be unique to JTR.
The PMR was implemented as part of the travel simplification process to create a single meal rate to replace the cumbersome meal-by-meal deduction and per diem adjustment. The PMR is an average amount of two meal rates - the lower daily meal rate (GMR) provided for three meals in a Gov't dining facility/mess and the higher full locality meal rate.
a. A member (not a civilian employee) is lodged in Gov't Qtrs on a U.S. Installation, and one or two meals are available in a Gov't dining facility/mess on the U.S. Installation;
b. A member (not a civilian employee) is lodged in Gov't Qtrs on a U.S. installation, with the GMR prescribed in the travel order, but the Gov't dining facility/mess was not available for all meals on some/all days;
c. A traveler receives one or two meals at Gov't expense (e.g., one or two deductible meal(s) on one or more days included in a conference registration fee); or
d. A member (not a civilian employee) is not authorized per diem but must purchase a meal (the PMR is the ceiling against which the traveler's actual meal cost is compared - the lesser of the two being paid).
The responsible DoD Component /Service representative and/or member (not a civilian employee) within the chain of command must contact the TDY location(s) to determine if Gov't Qtrs and meals are available for the applicable TDY period. Some of the Services have published Directories in the Lodging section of the DTMO website.
