This Choice Could Cost You 30% of Your Social Security Benefits
Ideally, you should retire with access to income outside of Social Security. That's because those benefits will only replace a small percentage of your wages, and you may need extra money to cover your living costs, from housing to food to healthcare.
Plus, you might just plain want more money so you can enjoy retirement rather than spend the bulk of it sitting at home because you can't afford to travel or pursue hobbies. So either way, coming in with a solid nest egg is a great idea.
But even if you manage to save nicely for retirement, you might still appreciate collecting as much money from Social Security as you can. One mistake, however, could cause you to lose out on a large chunk of your benefits.
