Retirement INCOME planning is the process of realistically forecasting what you want your life to be like at that point, and estimating what you’ll be spending money on year to year. Most people need a planner or advisor to act as a catalyst so they then take action and make decisions necessary to achieve those goals. Retirement income planning includes identifying sources of income, estimating expenses, implementing a savings program and managing those assets over time as the target gets nearer and being flexible to adjust the plan as life events change.
