Setting up your 401(k) contributions isn't rocket science, though it can feel that way, especially to those who aren't sure how much retirement will cost. There isn't a universal magic number, but there are a few pretty simple strategies you can use to come up with your retirement savings number right now.

What does your ideal retirement look like? Living in a tiny place and eating the senior special at 4:30 p.m. every day, or having a comfortable home and eating dinner whenever you want? You can create the easygoing retirement of your dreams if you know how to take full advantage of the perks available within your tax-advantaged retirement plans.
