It’s always difficult getting information regarding what you should be earning if you’re working for a salary; people tend to talk circles around you as soon as you ask how much they earn per month. Luckily IT WEB did a salary survey in 2008 and gathered the relevant figures for you.
The data is gathered and plotted on a bell curve which will typically look like this:
The lower quartile is typically where the density of values make up the first 25% which should be a good indication of what an entry level salary should be. The median is typically the density of values making up 25% – 75% which is a good indication of what your salary should be if you have some experience in the field. The upper quartile is typically the density of values making up the last 75% – 100% which should give you a good indication of what a good salary in a specific field is. The 90th percentile is the position where at least 90% of the values are less than or equal to the value labelled “90th Percentile”, this pretty much gives you an indication of what the salary ceiling is.
Without further ado, here are the results of the 2008 salary survey:
