Glassdoor.com ^[1] shows salaries listed by title and by company, which can at least give you a little more context.

The only really accurate gauge is to apply for other jobs and see what you get offered. A salary-guide is meaningless if you can't actually get such a job.

A former colleague actually applied for a job at a competitor just so he could take the information to his annual pay-review. The offer was slightly more than his then current salary, but not a huge amount more (I don't recall the figures involved). Our company wouldn't match the offer, and he changed employer...

In the UK I use http://www.itjobswatch.co.uk/ - it gives a good breakdown by location and industry. I find it helpful to talk to recruiters (finding a good one can be difficult though!) and discuss your salary aspirations with them. A good agent should be able to tell you if what you're after is realistic or not.

You are asking the wrong question.

Salary is completely meaningless once you are covering the basic bills.

Quick thought experiment.

You are fresh out of school and have a choice of 2 jobs:

Job #1: You clean toilets. 5 days a week. Salary: $150,000

Job #2: You work directly with Sergey Brin and get direct exposure to the upper workings of Google. Salary: $50,000

Based on salary -- Job #1 is the better choice.

A better question: Is the next year of 'experience' at your current job going to be the same as the last?

You should change jobs any time you are not learning 50% new things every single month.

Regardless of your current salary, even if it means a pay cut --- change jobs.

[Update: since SO doesn't allow commenting on your own answer unless u r l33t] :

@Till -- my example was for illustration-only --> substitute any deadend job you want.

@JasonMichael -- WTF? You completely missed the point being made, which is one is a completely dead-end job that happens to pay high. The other is a job that provides lots of experience that will be used later in life.

More information on this topic over at Lifehacker ^[1]

From that Lifehacker article, Indeed ^[2] is very easy to use and seems to be giving me some decent numbers. You just enter in a job title & zip code, and it gives you a list of closely related job titles & average salaries. It's far easier to use than salary.com.

In the past, I've used the Robert Half Technology 2008 Salary Guide ^[1]. It's published by a recruiting firm and you have to sign up to get access to it, but it seemed pretty accurate last time I looked at it.

There will be no straight-forward answer. With a big enough company or in the public sector (aka working for the government, whichever that country is for you) there will be published paygrades, but in general these will come in less than in the private sector, but perhaps with other benefits (quite often better pension schemes).

With smaller companies you might get more flexibility for the job to reward your ability, but again, get paid less with an expectation that the options package will be enough to attract the quality candidates.

Mid-range companies might then pay more, but will it be as much fun?

The only way to know is to ask actually people but, really, would you answer that question? My wife knows what I earn. My boss knows. So does my bank manager. I'd tell you a number but it's up to you if you'd believe me.

And if you're a recruiter, I'll probably tell you a different number, but that depends if I'm looking for a job or looking to employ someone.

And even when we do interview to fill a role, we are often really careful not to mention too specific a salary range. If it's too high then we get lots of chancers trying to inflate their current roles with a look to step up, but if it's too low then we don't attract the quality applicants.

There really is more to this than just a single bottom line figure.

I had a chance to check out Glassdoor ^[1] and while it's interesting information, it's not particularly useful because you can't filter by job title & location, which is really the information you need to figure out what your salary should be.

I've gone to the a few different salary sites and pulled the salary for 3 similar positions/titles positions I have/had in the area/zip code I plan to work in. Then average the salaries. So far this gives a decent base line on what you should expect. Then try to get higher obviously =).

Here's another useful (or well, at least interesting) site for IT salary benchmarking:

ActiveTechPros ^[1]

To use it, you must register and enter your own info. Then you can see salary stats grouped by country / job function / experience. For example, according to the site, someone in "software engineer" role with 3-5 years of experience gets paid on average 43,000€ in Germany, £33,000 in the UK, and C$56,000 in Canada. To me, it seems to have a decent amount of data for most (developed) countries (though surprisingly few users from the US).

But other than that (points 2 & 3 assuming you are currently employed):

1. If you have friends who work in the same or similar industry, talk with them.
2. Why not talk about it with peers in your current team (some of them, the ones you know better), if you really want to know. (In Finland we seem to have a "best practice" of bringing this kind of stuff up when you are drunk off your face in the late hours of some recreational team event. Your mileage may vary. :-)
3. Ask yourself this: are you happy with your current salary, considering your role in the team, how much responsibility you take, and so on? If you are, well... be happy - and don't waste too much of your life pondering over it. If not, take the issue up with your superior, and try to reach some kind of mutual understanding.

Personally, with a combination of all 3 of the above, really, and a little browsing on activetechpros.com, I think I have a good enough idea of where I stand.

In that 30-40K range, just consider how much experience or how strong are the skills that the company wants. For example, if a company states the salary range as $80K-110K for a position with 5 to 10 years experience, then you could set $80K = 5 years, $110K = 10 years with a linear scale between them, so 7.5 years is halfway between the extremes and so it is worth $95K.

Alternatively, consider if they want a beginner, intermediate or expert in some technologies. Some places want a senior developer to know their stuff inside out and backwards in some cases and so if you can show that then you could say that you'd want something near the top of that range.

Last but not least is to consider the side benefits of working at company X: Is there flex-time? Lax dress code? Working on cool technologies? Using cutting-edge development methodologies? Profit-sharing?
