How to determine tax impact of converting IRA funds to Roth IRA?

[PMIArts]

Is there a good way to run such a calculation?  Will the Roth IRA money need to stay untouched for 5 years?

Thanks for joining us today.

The easiest way to run that calculation is to take the amount you intend to convert and multiply it by your marginal tax rate.    For more precision, you can drop the number in your return and see what the effect is.  Safest to play with that in a dummy account so you don't degrade the integrity of the live account.
