Amazon is a large and varied company, and the amount they pay per hour can vary widely between different roles.
Generally speaking, hourly pay at Amazon ranges from $15 to over $30 an hour depending on job type and location. The range between $15 and $30 is usually based on the level of skill and seniority of the role.
At the lower end, Amazon offers a minimum wage of $15 an hour. Amazon's minimum wage applies to all full-time, part-time and temporary roles in the US. Areas in the US where the minimum wage is higher than $15 are paid at that particular rate.
On the higher end, the pay rate for salaried or professional positions could be anything from $30 an hour and up, the exact rate depending on the job role, seniority and location.
When looking for jobs available, you should always read the job description and check the pay rate carefully to understand exactly how much you will be paid.
