First thing to realize is that an M.Sc. Is almost never worth it financially. Your starting salary may be slightly higher, but people who worked for a year would probably have gotten a raise anyways, and would be at the same level when you start 1 year later. Also, they just spent the past year earning money, instead of spending money. This is especially important when you are young. A euro 100000 difference (their salary, plus your opportunity cost, and tuition) when you are in your early twenties will be worth about euro 1M by the time you retire. You will most likely never make it back. If you want to do it, you should be very honest with yourself and make sure money is not the reason you are doing it.
