Montana per diem calculator (FY2027)
Simple estimate: trip total is the per-day total times the number of days. Real claims prorate the first and last travel day M&IE at 75 percent; this calculator does not model that, so treat the result as a planning estimate.

How per diem works in Montana
Per diem has two separate parts. Lodging is reimbursed up to the nightly cap for the travel area: spend less than the cap and you are reimbursed what you spent, spend more and the difference is normally on you. M&IE is a flat daily allowance paid in full with no meal receipts required, and it is meant to cover meals plus incidental costs such as tips and fees. Federal travelers and service members on temporary duty (TDY) use these GSA rates in the continental United States, and many private employers and contractors use the same figures as their travel benchmark.
Two rules shape a real claim. First, M&IE on the first and last day of travel is paid at 75 percent of the full daily rate. Second, lodging is a cap, not an allowance, so there is no benefit to booking a room priced right at the cap. This page's calculator keeps the math simple on purpose: it multiplies the full per-day total by the number of days, without the 75 percent first and last day adjustment, which makes it a planning estimate rather than a claim figure.

Montana per diem FAQs
What is the highest GSA per diem rate in Montana for FY2027?
The highest listed rate in Montana is Big Sky / West Yellowstone/Gardiner, at $249 per day: $169 for lodging (October 2026) plus $80 for M&IE. Lodging caps change by month in many areas, so the same destination can cost more or less in another season.
What per diem rate applies to a Montana city that is not listed?
Any Montana destination outside the 4 listed travel areas uses the standard CONUS rate for FY2027: $113 per night for lodging plus $68 per day for M&IE, a total of $181 per day.
How is per diem calculated for a trip in Montana?
Add the lodging cap and the M&IE rate for the travel area to get the per-day total, then multiply by the number of days for a simple estimate. For example, Big Sky / West Yellowstone/Gardiner at $249 per day for 3 days gives $747. A real federal claim pays lodging only up to the cap based on actual cost, and pays M&IE at 75 percent on the first and last travel day.
Are Montana per diem rates the same all year?
M&IE is fixed for the fiscal year (October 1, 2026 to September 30, 2027), but lodging caps vary by season in many Montana travel areas. The tables here show the October 2026 lodging rate. Check the GSA per diem lookup for the exact month of your trip before booking or filing a claim.
