Janitorial Direct Cost Calculation Factors

When considering your direct job costs, what all do you consider in as a factor? I have this listed, but I don't know if these are the best or if I should have more. https://ibb.co/cSX9SycZ

On my list I have:

• Background Check
• Drug Screen
• Badge Uniform
• Clock-In Services

Each category, except clock-in services, considers turnover for the position per year, resulting in a more accurate cost.

I've considered these others, but I don't know how to incorporate them into the price:

• Recruiting
• Training
• Job advertising

Thanks for your help. Here's a screenshot of how it calculates it.  https://ibb.co/cSX9SycZ
