Retirement planning includes many things. It begins with analyzing your current situation in terms of assets, liabilities, taxes, savings habits, budgets, goals and dreams.
Then a projection is made using existing trends to see what your asset base will look like at or near your projected retirement date.
Using the results of the projection, recommendations are then made with an aim to maximize your assets and their income generating capacity by coordinating your savings and asset base with your Social Security options, pensions, and any possible future additions to your wealth via things like inheritance.
Income projections are laid out and compared to possible expenses which include healthcare, housing etc. to arrive at an estimate of your future income levels.
Retirement planning includes the use of IRA's, 401k's, Roth's, annuities, regular brokerage accounts, dollar cost averaging plans and Dividend reinvestment plans.
