EO's Retirement Planning Calculators
This site will disappear in late 2009.  If you are interested in any of these MS Excel calculators, please contact earlyoutdh@yahoo.com.  Thanks. 
How will my Social Security be taxed? Income taxes and Social Security
The marginal tax on SS benefits can be as high as 47% and depends on the amount of other income you receive, even though some of that income may not be taxable.  This calculator lets you enter your income amounts  and the amount of SS.  The results show how much of the SS is  taxed, an estimate of your total income tax and your marginal tax rate. The complex relationship between income taxes, the amount of SS you receive and the amount of your other income is demonstrated in these tables. Income and SS benefit amounts can be changed to look at different situations.
When should I start SS? (Test Version)
Should I start receiving SS at 62, wait until my normal retirement age or wait until I am 70?  When will I "catch up" if I wait?  This calculator gives you a look at these different scenarios.  Please see the Program Notes before trying the calculator.
Income taxes on a Roth conversion
Are you considering converting some of your traditional IRA to a Roth IRA?  This calculator will show you the amount of extra  income tax that will result from the conversion. 
General Considerations
The calculators presented here are not designed for high income tax payers.   In general, calculations for incomes that exceed the 28% tax bracket will not be correct.   AMT is ignored as is phase-out of deductions at higher incomes.    
About Macros in MS Excel
     The calculators are MS Excel spreadsheets and require that MS Excel be installed on your computer.  The calculators use macros to perform the calculations.   Your installation of  Excel may ask if you want to allow macros.  You must enable macros for these  calculators to function.  This question is asked to allow you to block  macros from sites that you do not trust.
