Hi Ctay,Basically what you need to do is run an analysis to see where the breakeven point is for the two options. An example of what this looks like for whether to take social security at age 62 vs. 66 can be found at the link below:http://www.newretirement.com/Services/Social_Security_Start_Age_Calculator.aspxDoes your employer's HR group offer any tools to help you model what the breakeven point is? There are a number of variables to consider including the benefit levels for each option, plus the projected change in your income from switching jobs. Bud Hebeler's site http://www.analyzenow.com/ has some good free programs to help you explore this yourself. You may also want to talk with Financial Advisor about your decision. This section gives you some background on the considerations for choosing a Financial Advisor.http://www.newretirement.com/Services/Professional_Financial_Advisors.aspx
