I was going to publish a blog post with Roth calculator at the end of the year. But I'll publish it now to let you see how a tax accountant does the math:
Traditional IRA vs Roth Calculator
Super simple to use. You can just click the Calculate button to see how things look using the default inputs. In most cases, the math shows people shouldn't use Roth accounts.
Nice! I played around with it a bit and the results were as I expected: higher tax rate at retirement tends to favor Roth, lower tax rate at retirement tends to favor traditional, equal tax rate is equal (with a slight advantage for Roth in the "hybrid strategy" since you're not paying dividend/capital gains tax on part of the investment). ChatGPT did well.
Small bit of coding advice to improve the display of calculated results: Replace instances of
.toFixed(2)
with
.toLocaleString('en-US', {style: 'currency', currency: 'USD'})
This will make the numbers show up like "$123,456.78" instead of "123456.78".
You could also apply a
style="text-align: right"
to the numeric table cells to right-justify the numbers, as is typically done in spreadsheets and other financial reports.
Apologies to everyone who's already suffered through me rolling out these links to screeds about Roth accounts in past, but @Alternatepriorities ? Here's the first blog post in a short series where I step through the tax accounting that shows why most people shouldn't "Roth."

That's a long article, but you sum up the main point nicely at the end:
Just to repeat this point, then, the big (massively big) insight one wants to keep in mind? The decision to use or not use a Roth-style account rests almost entirely on the top tax rate you pay today versus the top tax rate you will pay in retirement.
And just to repeat a point I already made (because it’s so important): Most people enjoy higher incomes when they work as compared to when they’re retired, so almost always the Roth-style account only costs an investor more taxes.
I agree entirely with the first paragraph. The second relies on an assumption that lower income in retirement will lead to lower marginal rates. I think the ACA really throws that assumption out the window for people planning to retire significantly earlier than Medicare age. A more nuanced case-by-case examination is now needed.
Just as one example I can point to
this recent thread where a family was worried about high RMDs in their old age and wanted to consider pros and cons of doing Roth conversions early in retirement while on ACA insurance in order to avoid RMDs pushing them into a high bracket later on.
I ran some numbers and found they (a married couple with a kid) would experience marginal rates in the 22-30% range when doing Roth conversions on ACA insurance while their AGI is in the relatively low ballpark of $60k-90k. ACA aside, the 22% bracket for a married couple covers taxable incomes in the $94-201k range, and the 24% bracket goes up to $383,900. This seems to indicate they would have been better off contributing directly to Roth while working, even with a gross as high as $400k, rather than doing a Roth conversion to realize this income while on ACA insurance with a gross income of $75k.
But we're really derailing the thread at this point. Bringing it back...
Options:
1) We have enough in money market to cover the difference between our after tax earnings and our total expenditure. We could just accept paying 22% tax this one time on earnings and cover the difference with that.
2) We can borrow from DW's 403b and pay it back over the next five years. We would borrow enough for the project and also to increase our 2024 contributions to said 403b enough to defer earnings in the 22% bracket.
3) I have an inherited Roth IRA that is 2 years into the 10 years before i have to cash it out. There is enough to cover at least half of the needed funds
4) I can sell taxable investments that are appreciated. It's a first in first out account, and the oldest shares have approximately doubled in value, so if I want to avoid paying 15% capital gains on about 1/2 I need to sell enough extra to put even more or our earned income into tax deferred accounts.
I'm leaning towards a combination of 2&3 especially considering SeattleCPA's point about the oversold benefits of Roth growth and that in any normal year of spend we would not pay any capital gains tax, but I'd love to hear other ideas or if someone sees a flaw in the plan.
Option 3 seems fine. Waiting for an extra eight years of tax-free growth could be nice, but it looks like you're talking about a principal amount in the $20k range and your tax rate isn't going to be that high anyway so the opportunity cost of cashing this out early isn't going to be very big.
I'm a fan of Option 4 though. Especially if you have extra room to contribute to retirement accounts, selling taxable stock to fill your tax shelters (and bump yourself down a tax bracket!) can be a great way to go. I know I've done this in recent lower-income years myself where I couldn't just cashflow retirement contributions without selling other investments. Just make sure you've thought through scenarios to access this money pre-59˝ in the event your spouse joins your FIRE. And, per the point above, make sure you're not saving 22% now to pay 30% later.
