Currently, I am earning 53k with holiday and other significant incentives, amounting to approximately 29k in perks. With the additional responsibilities and pressures, I would be looking to have a base pay in the 60,000 range and a bonus incentive package commensurate with my experience and responsibilities."

Before your interview, make sure you have researched the median salary for the position (and location). You can look at salary reviews on Glassdoor.com or Payscale.com.

Always make sure you give a salary range, not just a number. Providing a range allows you to negotiate down the road if you are given an offer. However, if you just tell the employer you are looking for 50K it doesn't leave room for negotiating later on. Also, make sure the lowest number of your range is something you are comfortable with!

Another great option is to tell the interviewer what you are currently earning and tell them that you are seeking a competitive offer.

"I am currently earning a base salary of 50K per year. I am looking for a position that will offer me competitive growth and salary."
