Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I added Federal tax by bracket to my model and estimated the headspace for Roth conversions before age 72, then estimated the tax saved on the converted amount.
I just can't get excited about this. It seems much ado about nothing. It is not a home run as mentioned by @RunningBum.
Well, it depends on the numbers in each situation.
It'll mostly depend on your tax brackets when you convert versus when that tax is ultimately paid. If you can convert now at 10% versus 35% later, then you're paying 25 percentage points less in federal taxes on those converted dollars. On a $50,000 conversion, that's $12,500 less sent to the federal government. Converting at 22% versus 24% is only 2 percentage points in savings, or $1,000.
It'll depend on how much you convert. On a $5 conversion comparing 10% versus 35%, that's only $1.25 in federal tax savings.
It'll depend on how much you have elsewhere. If you've got 10,000 krugerrands in your basement, you probably don't care as much. Or if you have a gold-plated government pension that is inflation adjusted and covers twice your living expenses, you probably also don't care as much.
It depends on how you view the deferred liability of taxes on the traditional IRA dollars you have. If you primarily focus on cash flow and the "pain" of paying taxes now on a Roth conversion, but plan on dying with money in your traditional IRA and don't care about someone else paying that deferred liability after you die, then that's something in your favor.
It'll depend on how you build your spreadsheet. If you don't build it accurately, then you'll obviously get inaccurate results. Things to model IMHO: investment growth, tax bracket growth, RMD divisors, SS start age, IRMAA brackets, IRMAA inflation adjustments, and state taxes.
@RunningBum with respect, what is your financial training? Mine is in both graduate school and as a business leader. I can't think of a financial action that does not come with an attendant analysis of payback, breakeven, NPV and IRR. This applies in my view to a Roth conversion.
If the concise business case for a Roth conversion can't be simply stated in 25 words or less, it doesn't get my attention.
I'm not @RunningBum.
I have an MBA from an institution that is accredited by the same organization that accredits Harvard's MBA program, which I earned on scholarship while also working full time.
I've completed courses in accounting and financial analysis, accounting decision making and controls, personal financial planning, global economics, and financial modeling.
I am a member of Beta Gamma Sigma, the international honor society for collegiate schools of business.
I am Ivy League educated and a National Merit Scholar.
I worked for 17 years for two Fortune 500 technology companies in R&D as an engineer and engineering manager of multiple teams of up to 15 engineers across two continents. I have one US utility patent, two trade secrets, and six defensive publications to my name.
I retired at age 46 and as of today have a 1.41% net WR, a paid off house, paid off car, and my three kids' college degrees fully funded.
As far as your use of payback, breakeven, NPV, and IRR, those are terms that all generally refer to cash flows. A Roth conversion is more like a grocery coupon. What's the NPV on getting a $1 off on a box of Cheerios that you were going to buy anyway?
A Roth conversion isn't a business, and that's not really what the term "business case" is properly used for, but anyway: "More after-tax spendable dollars." That's four or five, depending on how you think about the hyphen.
We all agree there is speculation in the tax arbitrage nature of Roth conversions. Everything in life has some element of speculation. The speculation may work as we expected, or it may not. No one knows beforehand.
@RunningBum mentioned he might pay 5%-10% on taxes less overall. This is the payback I am referring to.
@pb4uski provided a form of a NPV calculation.
@Gumby provided another form of NPV calculation.
Folks, the Roth topic can and should be quantified for people to make quantified, informed decisions.
So far none of this is appetizing to me. I will continue to read threads on this site and run models to see if I can get myself to see the light.
You generally seem to be using the terms payback and NPV incorrectly. If you're going to throw them around and argue for people making informed decisions - which I agree with, by the way - you may want to understand and use those terms better. You'll get more respect here I think.
Depending on the assumptions you make and the accuracy of your models and, as noted, your view on the embedded tax liability and the assumptions you make about that, you might find that they don't make sense for you.
If I were you, I'd focus more on making sure I was understanding things accurately and had my model accurate, rather than the rather normal result where something can be a good idea for one person and not for another. If I invest in a 529 and you don't, does that mean one of us is right and one of us is wrong? If I have a toddler who I expect will go to college and I want to reduce my state tax bill and you don't have a toddler, then our different circumstances means our different decisions make perfect sense.
