How This Calculator Works

• We use Google Maps APIs to find the nearest office using office_locations.json and calculate driving distance and time to the client site.
• If the distance is under 50 miles, we assume technicians commute daily.
• If the distance is 50 miles or more, we assume weekly travel (5-day workweek) with hotel stays during the week.
• For hotel costs, the number of hotel nights is the total project days minus 1 for the final day, multiplied by the number of technicians.
• Per diem is based on first/last day rates and a standard daily rate for the intervening days, determined by the project’s state from our per_diem_rates.json data.
• All partial days round up to a full day for calculations. (e.g., 1.2 days counts as 2 full days).
• "Half Mileage" is simply the total mileage divided by 2, often used in our internal processes.
• Travel times are expressed in hours, rounded up to the nearest half hour for one-way calculations.
