DPEs… how much do they make?

Some people in here might know the answer to this question, but I’m really just curious.

Does anyone know how much DPEs actually make? If you look it up on google it says 60-80k a year but that doesn’t seem right to me. I just had my CFI checkride earlier this week and the DPE charges $1600 for CFI rides and $900 for other checkrides. The area I train in is bone dry with DPE availability but with a lot of demand due to a ton of students needing checkrides. At my flight school it can take up to 2 months to get a checkride scheduled due to the lack of DPEs.

All that to say, do DPEs really not make bank? Obviously it’s gonna change based on where you live and the demand for DPEs but to make $1600 for 8 hours of work seems absurd right? And if she can charge $900 twice a day that’s a lot more than 60-80k a year right?
