1

Where are you going?

For CONUS trips, search official GSA data or enter the authorized rates manually. For OCONUS, enter the locality rates from the appropriate official source or your orders.

No rate loaded yet.

2

How long are you going?

Use the departure and return dates from the authorization. Choose a reduced factor only when the written authorization establishes one.

Trip length alone does not automatically reduce the locality rate. A reduced rate must be authorized under the applicable travel rules.

3

What did the trip authorize?

Leave unknown optional items blank. If actual lodging is blank, the report clearly labels its use of the authorized lodging ceiling as an estimate.

4

Were deductible meals furnished?

Count only meals that the applicable rules require you to deduct. Common-carrier meals and complimentary hotel meals generally do not reduce federal M&IE.

OCONUS planning

Outside CONUS, identify the rate authority before entering a number.

“OCONUS” covers more than foreign countries. It includes foreign areas and non-foreign areas outside the continental United States, and the responsible rate source can differ. Department of State tables cover foreign localities. DTMO publishes rates for non-foreign OCONUS locations and maintains military travel guidance. The written authorization, current JTR, and servicing travel or finance office remain controlling for a particular trip.

Foreign locality

Start with the Department of State foreign per diem table and match the exact country, locality, and effective month.

Alaska, Hawaii, or U.S. territory

Use the DTMO per diem lookup for the applicable non-foreign OCONUS locality.

Military installation

Check whether government quarters or meals are available and whether an installation-specific incidental rate applies.

Currency

Record whether the source is expressed in U.S. dollars and use the official voucher process for any required conversion.

Why MyPerDiem keeps OCONUS rates manual

An automated country search can create false confidence when a city has multiple published localities, when a rate changes during the trip, or when orders establish a special rate. Manual entry forces the traveler to identify the source and lets the report preserve a currency note. The calculation math remains visible, but the tool does not claim to select the controlling OCONUS rate.

Before relying on the estimate

  • Confirm the exact locality and effective date in the official table.
  • Check government quarters, government meals, and incidental-expense rules.
  • Determine whether lodging taxes are included in the published rate or handled separately.
  • Verify any reduced rate, exchange-rate method, leave period, or personal deviation in the authorization.
