Retirement planning involves a skill set that goes beyond basic financial planning or providing investment advice.
A retirement planner's job is to take all of your financial assets and create a plan that results in the delivery of reliable monthly income once you aren't working. They consider all of your assets including Social Security, pensions and 401(k)s, any part-time work you're doing, and how your spouse's income factors into the calculations.
A retirement planner will project out how much retirement income you may expect to have at what date, and which accounts to draw out of. They can show you how much you'll expect to pay in taxes and for health care costs. They show you how inflation may affect your spending needs, and what decisions will help put the future 80-year-old you in a more secure position.
Although other financial advisers will help you think ahead and plan for retirement.
