 Amount to convert
 Amount to convert from a Traditional IRA account to a Roth IRA. It is important to note that some high income households do not qualify for a Roth IRA conversion. Currently, anyone with an adjusted gross income over $100,000 cannot make a Roth IRA conversion. For the purposes of this calculator, we assume that your income does not limit your ability to convert to a Roth IRA.
We also assume that you are paying any taxes owed with funds that you have available outside of the IRA you are converting. The IRS treats any money not directly transferred to the new Roth IRA as an early withdrawal  even if that money is used to pay the tax bill caused by the conversion. If you do not have adequate funds outside of your IRA to pay the tax liability on a conversion, you probably should not consider converting your Traditional IRA to a Roth IRA.
 Nondeductible contributions
 Amount contributed to the Traditional IRA you are converting that was not tax deductible.

 Rate of return
 The annual rate of return for your IRA. This calculator assumes that your return is compounded annually. The actual rate of return is largely dependant on the type of investments you select. From January 1970 to December 2004, the average compounded rate of return for the S&P 500, including reinvestment of dividends, was approximately 11.5% per year. During this period, the highest 12month return was 64%, and the lowest was 39%. Savings accounts at a bank pay as little as 1% or less. It is important to remember that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for longterm investments. This includes the potential loss of principal on your investment.
