Very few of us will retire from the same employer that gave us our first job out of school. While some of those job changes might be involuntary, due to a layoff or termination or other circumstances beyond our control, eventually, we’ll be the ones to say goodbye.

That means knowing when to stay and when to go – and being aware that it’s not always easy to tell the difference at first glance.

If you’re contemplating a job change, here’s what you need to consider before you make the leap:

1. Will you make more money? (Are you sure?)

Money isn’t everything, but you can’t enjoy much of anything without it – constant worry about finances has a way of taking the joy out of life.

While a higher salary isn’t the only reason to take a job, most people want to see a steady increase in salary over time. If your present employer doesn’t offer much in the way of regular raises your best bet might be to move on to greener pastures.

Of course, before you take the cash and run, you better make sure it adds up to as much as you hope. Compensation isn’t just a matter of what’s printed on your paycheck. Make sure you aren’t trading higher contributions to health insurance or other before-tax benefits for a slightly higher paycheck… which will go to pay for those self-same benefits.

2. What are you giving up by leaving?

Unless your job is truly wretched, there are probably a few things you like about it, even if it’s just the people you work with or an easy commute. Make sure you’re looking at all the pros and cons of leaving and staying before you make up your mind – even if, in the end, it’s a pretty easy call.

3. Is there room for growth in your new position?

If you’re like most people, you probably don’t want to change jobs every year for the rest of your life, but you need to know that you’ll meet new challenges and learn new skills, even when you stay put. Ideally, your new role should come with the possibility of growing into another, higher position at the same company.

4. Does the corporate culture feel comfortable for you?

Everyone has their own idea of a good time, and that’s as true professionally as it is personally. While you might look at an open-plan office and see one big party of creativity and collaboration, another person might cringe and go running back to their cube. If possible, ask to take a tour of the office during your interview process. Pay close attention to the physical space, noise level, demeanor and behavior of the staff, etc. Do you see yourself working well there, and feeling comfortable? There’s no perfect company, but there is a perfect company for you.

5. Do you respect the people you’ve met so far?

You can’t tell everything about your future co-workers by what you see during your interview, but you can get a general vibe of what kind of personality shines at the company.

6. Will you learn something new?

There’s no way to be 100 percent sure that you’ll love your new job, but if you can learn a new skill while you’re there, you’ll have moved the needle on your career, no matter what.

7. If you had to get a new job next year, would it be easier or harder than it is right now?

Let’s say the worst happens, and you hate your new job – or your new boss foolishly decides you’re not a good fit. Will moving to this new position put you in a better or worse place than you’re in right now? Ideally, you’re leaving your current role in order to move to a situation in which you’ll gain experience, knowledge, skills, and a positive brand association that will help you in your career long after you’ve left your next job.
