Do you feel that you deserve a higher salary and need to ask for a raise? Let's look at the facts: You're long overdue for a raise. Your boss hasn't exactly been forthcoming with one. And sitting around waiting for him or her to give you a raise hasn't really been of much help.

So what are you waiting for? It's definitely time to ask for a raise. And with the following tips, you'll be able to do just that.

1. Access How Much Others Working in Your Field are Earning: The first thing you should do before you ask for a raise is learn about typical salaries in your field. You can get this information by using salary calculator tools like Salary.com and even looking at salary surveys. If you belong to a professional association, check with it to see if it has salary information available.

2. Evaluate Your Worth: Make a list of your accomplishments, skills and contributions. Figure out how much you can earn. Salary calculators and surveys generally present you with a range of salaries. You must determine where you should fit into this range. And to do this, consider the number of years you've been working in the field and the length of time you've worked for your current employer.

3. Prepare Your Argument: You really shouldn't approach asking your boss for a raise as an argument, but you may have to make your case. Arm yourself with information. Know what a normal raise is for someone with your experience and occupation. Think of it as selling yourself just as you would do if you were trying to get a prospective employer to hire you. That's why it is imperative to make a list of all the things you've accomplished for your employer.

4. Set Up an Appointment to Talk to Your Boss: You need to show your boss how serious you are about asking for a raise. Treat this as a business meeting and set up a time to meet with your boss. The most important thing is to choose an appropriate time of day, like an end-of-business-day meeting. Also, assess his or her mood and outlook that day. Is he or she ready to consider your request?

5. Present Your Case: Your boss may agree to give you a raise immediately with you having to do nothing more than ask him or her for one. But if that doesn't happen, you may have to do more to convince your boss you should get a raise. Present the material you gathered earlier, including the typical salaries in your field and your accomplishments. But be flexible. Would you consider a supplement in perks, time off, flextime or vacation time in lieu of a raise? The key is to negotiate.

6. Have a Backup Plan Ready: Before you walk into your boss's office to ask for a raise, think about what you will do if he or she says no, or agrees to give you a raise that is much smaller than the one you want. Will you quit your job or will you wait a while and then ask for a raise at a later date? Your answer will solely depend on what your boss says. For example, has your boss turned you down because of your performance? If so, ask yourself if his or her criticisms are valid. If they are, think about what changes you can make. If they aren't, then you may want to go where you are appreciated.

With these tips in mind, you will be able to ask for a raise in a jiffy and also expect immediate and favorable results.
