That is a very broad question with a whole lot of variables.
Salary is pretty good in large cities, or for the state highway patrol. Small towns and county sheriff's don't normally pay as well. However, if it is in a town/county where you are protecting many wealthy residents, the pay tends to be better.
Besides salary, there are many other "pieces" of your paycheck. These may include:
- shift differential. If you work 2-10 pm or 10 pm- 6 am.
- longevity pay: an extra amount for each year of service.
- Education pay: pay for having a degree, or, perhaps just for having some hours of college
- Certification pay: There are usually certification levels that you advance through using training and years of service: basic, intermediate, advanced, masters
- bilingual pay: if you speak a second language, esp Spanish or American Sign Language
- clothing allowance: we got this every 3 months
- specialty pay: k9, bike patrol, helicopter, etc
- Health insurance paid for by your employer
I live in San Antonio, where cadets are starting at $45,000.
Bowling Green starts at a little over $41,000, with an increase to around $45,000 upon graduation from the police academy. https://www.bgky.org/police/jobs/police-officer
