The answer, of course, is: that depends.
Will retirement happen at 70? 65? 50? Or even younger?
When retirement happens to you is dependent on when you begin planning for retirement. The earlier you begin, the earlier it can happen. You need to financially plan, save money, invest money, and over time, your nest egg will grow until you have enough money tucked away to support you through the golden years.
First, as always, begin at the planning stage. Before you can ask: When do I hope to retire? Ask this instead: How much money will it take to support my lifestyle when I retire? That amount of money will need to be socked away before your retirement dreams can happen.
Remember, social security has some serious issues. While it's been promised by the government to employees who participate by paying into it, don't count on anything. Plan on paying for everything yourself and if you do receive social security, all the better! We hope the program continues.
