Per diem can make or break your TDY experience. When you understand the system and know how to work it properly, you can actually come out ahead financially instead of just scraping by. Let me show you how.
Understanding Per Diem Rates
Here’s something that catches people off guard—per diem rates swing wildly depending on where you’re headed. Washington DC or San Francisco? You’re looking at over $200 daily. Some smaller installations? Under $150. Before you pack your bags, check the Defense Travel Management Office website so you know what to expect.
Per diem breaks down into two parts: meals and incidental expenses (M&IE), plus lodging. M&IE covers your food, tips, and those small purchases you make along the way. Lodging reimburses your actual hotel costs, but only up to the max rate. Different rules apply to each, which is where things get interesting.
Meals and Incidentals Strategy
Here’s the key to making money on TDY—the M&IE rate is yours whether you spend it all or not. Book an extended stay hotel with a kitchen and cook your own meals? That extra cash stays in your pocket. Just watch out for government meals, because those get deducted from your allowance. Skip mandatory dining facilities when you can to preserve your full rate.
One thing you can’t change—first and last travel days only pay 75 percent of the M&IE rate. No amount of creative scheduling will fix this, so just factor it into your budget from the start.
Lodging Considerations
Lodging works differently than M&IE. You only get reimbursed for what you actually spend, up to the maximum rate. This means there’s no financial benefit to staying in a dump—you might as well find comfortable lodging close to the max rate instead of suffering to save money you won’t see anyway.
For longer TDYs, extended stay hotels often work out better. Weekly rates can come in under the daily per diem while giving you a kitchen and more space. Plus, being able to cook helps you maximize those M&IE savings from not eating out constantly.
Receipt Requirements
Never skip this part—lodging always requires receipts. You need itemized hotel bills with zero balances to keep auditors happy. Other expenses over $75 need receipts too. Trust me, keeping organized records during your trip beats the headache of voucher problems later.
Do yourself a favor and go digital with receipt storage. Email them to yourself or use an app, because physical receipts have a way of disappearing. I take photos of every receipt right when I get it. Those backups have saved plenty of travelers from denied reimbursements.
