A major part of the process of accepting a job offer -- whether for an entirely new job, a lateral move within a company you already work for, or a promotion in an existing job -- is negotiating the conditions of that job, including compensation. Some people find talking about money difficult. But if you fail to ask for more money in job interviews, you could lose tens of thousands of dollars over the course of your career. Preparation will help you ask for more money with confidence.
Research typical salaries or wages for the position for which you are being hired. Look at averages within that level of that particular industry. Examine compensation data for that particular company if that information is available. Knowing what is typical will help you evaluate the initial offer the company makes and give you ammunition -- and confidence -- in asking for more.
Assemble evidence of your credentials -- that is, of the reason you deserve more money than is being offered. Document your specific accomplishments in past and current job positions.
Practice the compensation negotiation portion of the interview beforehand, especially if you tend to get nervous in interviews or if you have little experience with verbal negotiations. If possible, practice with a career coach or another experienced job professional. Get comfortable with the idea and verbal mechanics of negotiating phrases like "That seems a little low" and "Would it be possible to raise that figure?"
Steer the interview to the topic of money if the person interviewing you does not bring it up. This can be as simple as saying "I'd like to discuss the compensation you're offering for this position" or "What did you have in mind for a salary?" Stay relaxed yet confident. Prompt the interviewer to state the offered wage or salary.
Counter the interviewer's offer by asking for more money. You can either ask broadly or specifically. For example, you could say, "I want to take this job, but would it be possible to raise the salary so it is more in line with the industry average?" or "A rate of $25 an hour would be more appropriate because the ongoing education needed to retain the certification you require is quite expensive."
