Preparing for retirement is tough regardless of your age, but it can be particularly challenging if you're in your 40s.
At this age, you may have a mortgage to worry about, kids to put through school, and you might still be paying off student loans -- not to mention all of the other everyday expenses that put a strain on your bank account.

However, your senior years will be here before you know it, so it's crucial to start saving now. Retirement is more expensive than you may think, and you'll likely need to stash away several hundred thousand dollars (or more) to retire comfortably. If you haven't begun saving yet, here's how to get started.
