Calculate your per diem for fast, accurate travel cost estimates

Easily calculate per diem rates for travel expenses. Whether you're planning business trips or managing employee reimbursements, our calculator provides state-specific estimates to ensure accuracy.

How to calculate per diem allowance

Our per diem calculator takes the guesswork out of estimating travel expenses. It uses the most up-to-date rates provided by the General Services Administration (GSA) for federal employees and travelers. Follow these simple steps to ensure accuracy for your business travel:

  1. Enter your travel details: Start by inputting your departure and return dates, and select the location of your trip, including state and city. If you've taken multiple trips, the calculator allows you to add each destination for a complete estimate.
  1. Understand expense categories: The GSA defines per diem rates for lodging, meals, and incidental expenses (M&IE). Lodging rates may vary depending on the season, while M&IE rates remain consistent throughout the year.
  1. Get accurate estimates: The calculator applies the latest GSA rates based on your input, providing an up-to-date estimate of your travel allowance.
  2. Calculating for multiple trips or locations: For trips involving multiple destinations, easily add each location to get a total per diem estimate tailored to your travel schedule.
