Meal breakdown and travel days
On the first and last day of travel you receive 75% of the M&IE rate. When the government provides a meal, that meal's amount comes off the day's M&IE; the incidentals portion is always kept.
| M&IE rate | Breakfast | Lunch | Dinner | Incidentals | Travel day (75%) |
|---|---|---|---|---|---|
| $68 standard | $16 | $19 | $28 | $5 | $51 |
| $74 | $18 | $20 | $31 | $5 | $55.50 |
| $86 | $22 | $23 | $36 | $5 | $64.50 |
Military travel notes
- TDY uses these locality rates (Joint Travel Regulations, chapter 2). Hotel taxes in CONUS are reimbursed separately, on top of the lodging ceiling.
- PCS travel days do not use locality rates. Driving pays a flat $181 a day (the standard rate) wherever you stop. See the PCS calculator.
- Work out a specific trip, including provided meals, in the per diem calculator.
