In my experience I think location (mainly), industry, and the company you work for has an effect.
I didn’t choose an especially lucrative industry (dig marketing) mainly because I fell into it for first internship, found it easy and thought it’d be easier to carry on in same direction. I had no interest whatsoever tbh, but when I was applying for my first internships no other decent role was offered.
I have a degree and around 2 years experience in my industry, but live in a northern city.
I’m on roughly 25k (not in entry level role) which is about the same or even less than starting salaries for entry level roles in my industry based in London/SE.
I would love to relocate down south one day.
Also, I’ve noticed that there is a huge disparity in pay for similar roles to mine depending on company e.g., some prestigious firms which ask for a similar level of experience will pay a LOT more.
However, better paying jobs at such firms are much more competitive as you’d expect, so I’m sure the candidates will have a much better background than I do.
Out of curiosity I just googled the average salary in my industry, and according to Reed it’s only £29k. Interesting how experienced managers in my industry who work e.g., up north for medium sized company may only get £30k which is the same as some graduate schemes.
I do worry a lot about money and have tried switching industry before but have never been successful in applying for other roles
