Your monthly budget is an underlying part of your salary negotiation strategy. Knowing your budget helps you identify your absolute minimum salary requirements.
Whether you are asking for a raise from your current employer or negotiating a salary with a future employer, knowing the salary range for your position is crucial. Get an approximate range from sites like Payscale and Salary.com.
You could use 10 percent over your current salary as your target and twenty percent more as your ideal. Set a goal of negotiating a wage between your target and ideal numbers.
Some cities and states have banned employers from asking questions about salary history, but it could come up. Avoid disclosing your salary history if asked about it during an interview.
