Per Diem Calculator — free online tool
Planning a work trip and trying to figure out how much you'll actually get for meals and small costs? The daily rate is the easy part. The headache is that first and last day, when you're only traveling for part of it and the rules pay you less. We added a free tool that does the math for you — Per Diem Calculator — right in your browser.
What it does
You type in your daily rate and the number of days, and it adds up your total travel allowance. It knows the 75% travel-day rule, so the day you leave and the day you come back are counted at the reduced amount instead of the full one. You get a clear total without doing any of the arithmetic by hand.
Nothing leaves your device
Everything runs right here in your browser. The numbers you type stay on your screen — nothing is sent anywhere, nothing is uploaded, and nothing is saved. When you close the tab, it's all gone.
How to use it
- Open the Per Diem Calculator and enter your daily rate.
- Put in how many days the trip lasts, including the travel days.
- Read your total allowance at the bottom, with the partial days already taken care of.
It's free with no limit. There are more small tools on the Apps page.
