Teapot vs Boldin: Tax Efficient Withdrawals and Roth Conversion Accuracy

A retiree we heard from had been using Boldin for two years. They liked it. The projections felt comprehensive. The Social Security optimizer was helpful. They felt like they had a real plan.

Then they sat down to actually figure out the withdrawal order for the year. They had $800,000 in a traditional account, $350,000 in a Roth, and $180,000 in a taxable account. They wanted to draw most of their spending from the taxable account this year — it had low embedded gains and would be nearly tax-free to sell — while pulling a modest amount from the traditional account to fill their lower bracket, leaving the Roth untouched to keep growing.

Boldin defaulted to taxable first. That part was right. But when they tried to blend in traditional account withdrawals at a specific amount while leaving Roth alone, the tool would not let them customize the sequence. One reviewer put it directly: if you want to blend tax-deferred and tax-free withdrawals in retirement, this software cannot handle that.

For a retiree whose biggest remaining tax lever is withdrawal sequencing, that gap matters.

Boldin covers a wide territory. It models Social Security timing, spending throughout retirement, basic estate planning, and gives users access to advice-only financial advisors without sales pressure. The platform has an active user community and an extensive content library. For someone who wants a single place to track net worth, run broad retirement projections, and occasionally consult a fee-only advisor, Boldin delivers on that scope.

Withdrawal Ordering Is Fixed

Boldin's withdrawal strategy defaults to drawing from taxable accounts first, and the tool does not support customizing a blended sequence across account types. For retirees managing Traditional, Roth, and taxable accounts simultaneously, this is a significant constraint. The order you draw from those accounts over 20 to 30 years can be worth tens of thousands of dollars in lifetime tax savings. A tool that locks you into a default order limits the accuracy of its own projections for anyone whose optimal strategy differs from that default.

Taxable Account Tax Treatment Is Approximate

Boldin does not let you specify the tax treatment of individual investments in your taxable account. That means the tool cannot accurately model the tax impact of selling a specific position based on its embedded gain, holding period, or cost basis. Reviews note that this makes the tax calculation for taxable account withdrawals unreliable for anyone whose taxable account has positions with varied gain profiles.

The Roth Conversion Explorer Has Gaps in Its Tax Stack

Boldin's Roth Conversion Explorer does automatically evaluate conversion strategies — it cycles through federal tax brackets and identifies which bracket-fill approach maximizes estate value or minimizes lifetime tax. That is a real capability. The gaps are in what the optimizer includes. Boldin's own documentation acknowledges that the Explorer does not model ACA subsidy loss when evaluating whether a conversion makes sense, does not factor in the 5-year Roth conversion rule, and does not account for early withdrawal penalties. For anyone still on ACA health insurance during a conversion year, or who needs to manage a 5-year seasoning window for penalty-free Roth access, those are material omissions. Teapot folds IRMAA, ACA subsidy cliffs, NIIT, and state brackets into the tax calculation for every conversion year automatically.

The Setup Takes Time

Boldin is comprehensive in scope, and comprehensiveness requires comprehensive input. Users consistently report that the initial setup takes at least an hour and can feel overwhelming for someone who has not previously worked through a detailed financial plan.

The most significant practical gap between the two tools for retirees who are actively drawing down accounts is how withdrawal ordering is handled. Boldin limits how you can mix account types; Teapot does not offer arbitrary per-year mixes either, but it applies a transparent priority and full tax stack each year.

Teapot's withdrawal calculator tracks Traditional balances separately for each spouse. Each year it uses a threshold-aware draw priority — taxable first, then Traditional up to the point where the next federal bracket or IRMAA/ACA cliff would be crossed, then Roth for the remainder, with Traditional as a fallback if Roth is insufficient — and iterates until net spending after tax is met, with IRMAA lookback, ACA thresholds, RMDs, and state brackets applied in the projection. Taxable sales use one blended unrealized-gain ratio for the account (not security-by-security lots). The result is a year-by-year plan that shows where cash is drawn from, what the tax cost is, and how each threshold is being managed.

This matters because withdrawal sequencing and Roth conversion are not independent decisions. The amount you withdraw this year occupies bracket space that affects how much you can convert. The amount you convert changes your taxable income, which changes what you need to withdraw to meet spending after tax. Boldin addresses these as separate plan settings. Teapot solves them together: the threshold-aware withdrawal engine runs inside the same simulation loop as the conversion tax calculation, so bracket space is never double-counted between the two.

Boldin's Roth Conversion Explorer is designed for "what if" analysis. You enter an amount, it shows the impact. Finding the right amount requires testing scenarios manually.

Teapot's approach is different. It simulates a predefined set of conversion strategies — for example no conversion, bracket-fill to each marginal rate, and frontload variants — with IRMAA, ACA, and other cliffs folded into taxes each year, then ranks outcomes by after-tax ending wealth. You see the year-by-year tax cost, cliff exposure, and account balance trajectory for each strategy. The best-scoring path is identified for you, not derived through manual iteration. Because withdrawal amounts are recalculated inside each strategy's simulation, the conversion ranking reflects the actual net cost after spending needs are met — not a hypothetical where withdrawals are held fixed.

Boldin is a reasonable fit for people who want a broad all-in-one platform covering budgeting, net worth tracking, Social Security optimization, and occasional advisor access — and whose primary questions are around projections and income timing rather than granular tax planning.

Teapot is a better fit for people who want tax-aware withdrawals with a clear account priority, an automatic Roth conversion comparison across predefined strategies with IRMAA and ACA in the tax layer, or couples planning with per-spouse account tracking and state brackets for all 50 states.

Boldin covers a lot of ground, and many users find it sufficient for general retirement planning and Social Security timing. Where it falls short is in the precision of the tax planning layer — withdrawal ordering is constrained, and Roth conversion analysis requires manual iteration and is missing ACA subsidy and 5-year rule modeling.

Where Teapot differs: withdrawal ordering is threshold-aware rather than fixed, the optimal Roth conversion strategy is found for you automatically, and setup takes minutes rather than an hour.
