How to Calculate Your Per Diem Allowance?
Calculating the correct per diem amount is crucial for accurate reimbursements and budgeting. Our calculator uses the latest rates set by the U.S. General Services Administration (GSA) to provide reliable estimates. Here’s how to use it:
Enter travel dates & destination: Input your trip's start and end dates. Then, specify the state and city (or county) where you'll be traveling. The rates often vary significantly by location.
Specify trip details: If your travel involves multiple stops, you can add each destination separately to ensure the total allowance reflects the rates for each location visited.
Understand the breakdown: The calculator will show the standard allowance broken down into lodging costs and M&IE (Meals and Incidental Expenses). Remember that lodging rates can sometimes change seasonally in certain areas, while M&IE rates typically stay consistent throughout the fiscal year for a given location.
Get your estimate: Based on your inputs, the calculator instantly provides the estimated per diem allowance according to the official GSA rates for your travel period and location(s).
