How To Negotiate A Raise

Step 1: You will need

Salary research for your profession.
Your career performance.
Analyses or on-the-job reviews.
Once you have these things together, it's pretty simple.

Step 2: Know your worth

Your research should tell you what your peers are making based on experience, seniority, market, and performance. This should give you an idea of the range that you should shoot for.

Step 3: Schedule a meeting

After you have your information together, ask your supervisor to discuss your salary with you.
You need to do the work for them and present a case that's ironclad and undeniable. Your performance reviews should provide some good evidence. Show areas where you excel, and point out areas where you have shown improvement.
Many employers have policies for giving annual raises. Make sure you are aware of any such policy before heading in.
Plead your case citing your evidences in a rational, business-like way, and respectfully present your new range of compensation.

Step 4: Be flexible

Instead of handing over more cash each week, your employer may offer other ways to increase your earnings by adding benefits, stock options, or they may simply give you more time off. Consider that although this may not look like immediate cash in your pocket, in a less direct way, it IS.
