Per Diem Calculator
Work out the total per diem allowance for a business trip in seconds. Enter your daily meals and incidentals rate and your nightly lodging rate, then set the number of full travel days and whether the first and last days count as full or reduced days. Many employers pay only a portion of the meals rate on partial travel days, so this tool lets you apply a common seventy five percent rule to the first and last day while paying the full rate in between. It adds lodging for each night and totals everything into one clear figure you can put on an expense report. This is a general calculator, so always confirm the exact rates and rules your organization or the applicable government schedule uses. All math runs locally in your browser.
