Total Cash Compensation (TCC): TCC combines base annual salary or hourly wage, bonuses, profit sharing, tips, commissions, and other forms of cash earnings as applicable.  It does not include equity (stock) compensation, cash value of retirement benefits, or the value of other non-cash benefits (e.g. healthcare).

Typical Median Pay: The median pay is the national median (50th Percentile) annual total cash compensation.  Half of the people doing the job earn more than the median, while half earn less.

Range in pay within a job can be very wide depending upon years of experience, scope of responsibility, location of work, etc.  For example, pay can be higher than the stated median pay if the worker has more responsibility, chooses a higher paying field, or works in a city like New York.

Percentage of Low Job Stress: The percentage of respondents who chose the three least extreme options for stress: My Job is Relaxing, Not stressful, and A Little Stressful, for the question, "ow stressful is your job/work environment?"

Percentage of High Job Meaning: The percentage of respondents who chose the two most extreme options for job meaning: Yes and Very Much So, for the question, "Does your work make the world a better place?"

CEO-to-Worker Ratio: The ratio of a typical worker's pay compared to a company's CEO pay.

Percentage Above or Below Market: This measures whether a given employer typically pays above, below or at market price for their employees. By utilizing PayScale’s database of over 40 million employee profiles, we have determined how various compensable factors, like work experience, education, and job responsibilities, affect pay, when all else is held equal. From this analysis, PayScale can then calculate what a worker with a given set of compensable factors will earn across different employers.

This measure is reported as a percentage premium or loss. Any employer that pays above market will have a positive percentage. The larger the percentage, the higher the premium these employers pay for their workers. On the other hand, if an employer pays below market, the percentage will be negative.
