Per diem rate calculator

For most CONUS locations the standard rate is $110 lodging plus $68 M&IE ($178 per full day). About 300 higher-cost localities have their own lodging caps and M&IE tiers.

Look up the GSA locality for the destination and dates. Lodging is the monthly cap times each overnight (never prorated). M&IE is the daily meals-and-incidentals amount: 100% on full days and 75% on the first and last travel day. Trip total = lodging nights + full-day M&IE + 75% first/last-day M&IE, minus any government-provided meals.

On the first and last calendar day of a trip, GSA reimburses 75% of the daily M&IE rate. Lodging is never prorated. A three-night trip is four travel days: two at 75% M&IE and two at 100%.

No. This is an independent per diem rate calculator that looks up published GSA CONUS tables (the same figures as gsa.gov). It is not a government website. Confirm amounts with your agency and the Federal Travel Regulation, and use gsa.gov/perdiem when you need the official source.

No. Per diem is lodging plus M&IE for an overnight trip. Mileage is a separate privately owned vehicle (POV) reimbursement, generally the IRS standard mileage rate under the Federal Travel Regulation—not a GSA lodging table. Washington and other states may publish their own mileage rates for state employees.

GSA sets federal CONUS locality lodging and M&IE (used on this homepage calculator). The IRS sets special transportation-industry meal rates for qualifying over-the-road truck drivers ($80 CONUS / $86 OCONUS from Oct 1, 2025). Use the trucker calculator for IRS transportation rates; do not apply GSA city tables to OTR miles unless your employer says to.

This tool is GSA CONUS (48 states + DC). Military and DoD travel often uses Joint Travel Regulations and DoD per diem (including OCONUS). Those tables are not the same as GSA. Use this calculator only when your orders or policy point to GSA CONUS rates.

Open this calculator and pick a state, locality, or ZIP, or browse GSA rates by state. Cities not listed as a GSA non-standard area use that state's standard CONUS rate. Examples people search: Seattle, Tacoma, Las Vegas, San Diego, Phoenix, Minneapolis, and Washington, DC.

Use the standard CONUS rate for that state. GSA publishes localities (usually a key city plus county), not every town. Enter a ZIP in the calculator to map to the correct destination.
