Typically when candidates are moving from a salary to an hourly rate they should look to make 20% to 50% on top of their current salary, to cushion for additional expenses that independent workers take on. Your hourly rate can be calculated by dividing your salary by 2080 (working hours in a year, assuming a 40 hour work week), then multiplying that total by 1.2 to 1.5. The standard equation is: (Current salary / 2080) X (1.2 to 1.5).
