If you have existing retirement assets in a traditional IRA, you may want to consider converting those assets to a Roth IRA. Possible benefits of converting include tax-free distributions at retirement, no required minimum distributions at age 70 ½, and leaving income tax-free assets to your heirs in the event of your death.
In order to plan realistically for the future you need to have a clear understanding of what money you need when you retire. This will include the cost of living and special activities you will have. It is estimated that you will need to replace 60% to 80% of your pre-retirement earnings in order to keep the standard of living you have had thus far.
