Meals & Incidental Expenses Breakdown

The meals and incidental expense (M&IE) breakdowns in the table below are provided should federal travelers need to deduct meals furnished by the government or included in a registration fee from their M&IE allowance consistent with Federal Travel Regulation 301-11.18. Meals provided by a common carrier or a complimentary meal provided by a hotel/motel do not affect per diem (301-11.17).

Per Diem Highlights

We establish the per diem rates for the continental United States (CONUS), which includes the 48 contiguous states and the District of Columbia. Federal agencies use the per diem rates to reimburse their employees for subsistence expenses incurred while on official travel.

Federal per diem rates consist of a maximum lodging allowance component and a meals and incidental expenses (M&IE) component. The standard rate of $178 ($110 lodging, $68 M&IE) applies to most of CONUS. For fiscal year (FY) 2025, there are 296 non-standard areas (NSAs) that have per diem rates higher than the standard rate.

Since FY 2005, we have based the maximum lodging allowances on average daily rate (ADR) data. ADR is a widely accepted lodging industry measure derived from a property's room rental revenue divided by the number of rooms rented. This calculation provides us with the average rate in an area. For more information about how lodging per diem rates are determined, visit influencing lodging rates.

The Federal Travel Regulation (FTR) allows for actual expense reimbursement when per diem rates are insufficient to meet necessary expenses. Please see FTR § § 301-11.300 through 11.306
