There are retirement rules out there that serve as good guidelines but it doesn't mean that you have to follow them. Especially for millennials, it may be better to consider bending some of these rules. 

 

Rules that you can bend:

1) Saving 15% of your salary per year for retirement

- Make sure that you save more in some years to counteract the years you haven't saved enough.

2)  Picking a target-date fund after the year you retire

- Try selecting a fund not based on the year in its name, but on how it invests.

3) Subtract your age from 100 to determine your asset allocation

- Try an asset allocation tool instead.

4) Build an emergency fund before saving for retirement

- You just need enough savings to cover sudden expenses, try taking advantage of your employer 401(k) matching as soon as you can.
