Is there a way to model conversion of a portion of our qualified funds? As far as I can tell, the only option available is to convert 100%. We would like to model converting only a fraction....
Yes, you can model only a fraction. On the Roth conversion page, the table on the left side of the page gives you the ability to specify the specific years in which you want to do conversions, and it also gives you the ability to restrict the annual amount via any of these methods: marginal tax bracket, LTCG bracket or IRMAA bracket. Then, the table on the right side of the page shows you exactly what's happening. Specifically, it shows you how much is being converted each year and the limiting factor, such as tax bracket, IRMAA, etc. You just have to manually adjust the parameters until you get the result you want.
