Free Per Diem Calculator

The Watson CPA Group has developed this free per diem calculator- created by a pilot for the crewmember industry. While this is generally used for taxpayers in the aviation or airline industry, all travelers might find it beneficial. If you need per diem rates including lodging, we suggest reviewing our Per Diem Methods and Rates page.


Pilot per diem and flight attendant per diem is typically a great tax deduction, when it’s computed and deducted properly. If the Watson CPA Group prepares your flight crew tax returns, we compute your per diem allowance and deduction for you at no additional charge. No worries- We encourage Do-It-Yourselfers to use our program for a free per diem calculation.


International destinations except Canada, Mexico and Caribbean are not available in this calculator. If an airport is not listed, we will be notified by our web site, and we’ll add it right away. For pilots and flight attendants who have international destinations, we recommend


Once you enter your flight schedule, you can print the report, email the report to yourself or send the report to us for tax preparation. We hope you enjoy this nifty airline per diem calculator.


2015 Tables

We have just finished uploading our 2015 per diem rates into our free online per diem calculator. Remember, we only populate North America airports including Hawaii, Alaska and the Caribbean. If you need international per diem calculations such as LHR, SAP, NRT, etc., we recommend


As a side bar, federal per diem rates changed dramatically in fiscal year 2016 (which starts Oct 1 2015). Los Angeles county, for example, actually went down. Nutty. And several other counties went up. This is the greatest movement in per diem rates we’ve seen in a long time. Usually it is lather rinse repeat, but not this year. Stay tuned. Yet on a brighter note, the standard daily rate for transportation workers increased from $59 to $63 for CONUS and from $65 to $68 for OCONUS.


We’ve also loaded our 2015 data into the 2016 table. This will allow you to make entries into our calculator for the current tax year as a record keeper. In December of 2016 we’ll update with current data, and your calculation will be complete (thanks to Rex for the idea).


Apple Users Alert

WARNING: We have had a handful of users have problems while using Apple products such as iPads along with Safari as the browser. We suggest Firefox for these users. And we also suggest perhaps entering only a few overnights, saving the schedule, and generating a report to ensure compatibility before entering the whole year. Sorry for the hassles.
