Retirement planning is the process of determining retirement income goals, and the actions and decisions necessary to achieve those goals. Retirement planning includes identifying sources of income, sizing up expenses, implementing a savings program, and managing assets and risk. Future cash flows are estimated to gauge whether the retirement income goal will be achieved. Some retirement plans change depending on whether you’re in, say, the United States, or Canada, which has its own system of workplace-sponsored plans. Retirement planning is ideally a lifelong process. You can start at any time, but it works best if you factor it into your financial planning from the beginning. That’s the best way to ensure a safe, secure—and fun—retirement. The fun part is why it makes sense to pay attention to the serious and perhaps boring part: planning how you’ll get there.
