How we compute these numbers

We read each job from the job board of the company and check it every day. We use only open jobs that state a yearly pay range in US dollars. One job counts with the middle point of its posted range. The median is the middle value of these amounts: half of the jobs are above it and half are below it.

We do not use a range with a bottom below $15,000, a top above $1,000,000, or a top that is more than four times the bottom. A company needs 5 or more open jobs with posted pay to have a page. Jobs under the same company name count as one company.

The numbers are base pay as the company posted it. They are not the pay of a person, and they do not include stock, a bonus or benefits. For the stock and the bonus that people reported, see Reported pay.
