The Roth IRA Converter Calculator shows you vividly and dynamically whether it is worth converting your traditional IRA to a Roth IRA. The calculator takes into account if you pay your conversion taxes out of IRA proceeds or if you pull them from other sources. The results are shown as a traditional deductible IRA, conversion to a Roth IRA paying taxes out of the IRA distributions and conversion to a Roth IRA paying taxes out of funds outside of the IRA distributions.
