So, you've started a new job. Well, though you may be beyond excited that you got a job. It's really important to negotiate your starting salary. Here's why:

A study done by lifehacker shows that if you don't negotiate your starting salary when you begin a job in a career type field that it can end up costing you around 600K when all is said and done.

Now, this doesn't mean that you have to go in and demand a whole lot more money. If you're offered a job at around 40-50K asking for only about 5 thousand more is enough to make you that much more money over a life time.

The study found that most of the raises you receive are based on a percentage of your salary. So, it's really important to start out with as much as you can have.
