Answer:
This answer will vary widely by the setting you work in (Early Intervention, public school, SNF, hospital/rehab, etc) and your location. For example, I am an SLP working in a public school in MA in a district that doesn't have a lot of money (the percentage of students who qualify for free/reduced lunch is around 50%). In my district, SLPs are paid on the same scale as teachers in the district, and a first-year teacher with a Master's degree will earn around $40,000. In a wealthier school district, this figure would be higher. This salary figure will also be higher if you're working in a medical setting or, potentially, in a private practice. To get a more precise figure, you'll need to research your specific geographic area. If you're thinking of working in the public schools, this information should be readily available in public documents.
