FYI, you should use the following as this is the calculation for a full time employee (FTE):
I think 12 hours a day is quite a reach lol.
An FTE is the hours worked by one employee on a full-time basis. The concept is used to convert the hours worked by several part-time employees into the hours worked by full-time employees. On an annual basis, an FTE is considered to be 2,080 hours, which is calculated as: 8 hours per day. x 5 work days per week.
So, Your annual salary of $160,000 would end up being about $76.92 per hour.
I can work 12 hour days, but my hourly doesn't get broken down that way, as I'm only getting paid for 40 thus, you should look at the normal rate for a 40 hour work week.
