Most retirees focused on lowering their lifetime tax bill think of Roth conversions as the main lever. The conversion math gets all the attention. But how an IRA is invested — what it costs to hold, how it gets traded, how it gets managed — quietly determines how much wealth is actually available to convert in the first place. A Roth conversion doesn’t create wealth. It converts existing wealth into tax-free wealth.
After more than 14 years of building multi-year conversion plans for IRA Millionaire households, our team has watched three specific forms of investment drag undermine otherwise sound conversion strategies. These drags often look small in isolation, sound responsible on the surface, or feel like expertise — which is what makes them hard to catch. This article walks through what each drag looks like, how to diagnose it inside your own IRA, and what an optimized investment setup looks like before any conversion strategy gets layered on top.
Why Investment Choices Determine Roth Conversion Outcomes
A Roth conversion shifts pre-tax dollars from a traditional IRA into a Roth IRA — paying ordinary income tax on the converted amount now in exchange for tax-free growth and tax-free withdrawals later. The math can produce well into seven figures in lifetime savings for an IRA Millionaire household. But the math operates only on dollars that actually exist inside the account.
Consider two households running an identical conversion strategy. One starts conversion year one with $1.5 million in the IRA. The other starts with $1.8 million, having avoided years of unnecessary investment drag. Same strategy, same tax law, same time horizon. Very different tax-free balances at the end. The difference traces back to what was happening inside the IRA long before the first conversion.
Audit Your IRA Before Converting
Our team has built more than 2,400 multi-year conversion plans, and the first step is always identifying what’s quietly draining the IRA before the conversion math even starts. Find out whether your current setup is helping or hurting your strategy — with no product pitch and no obligation.
That is why an IRA audit comes before a conversion plan. The right question isn’t only “how much should be converted and when?” It is also “how much is even there to convert?”
The Vineyard Analogy: Why Strategy Can’t Fix a Weakened IRA
Our team often uses a vineyard analogy to explain this point. The IRA is the vineyard — the asset that produces the harvest. A Roth conversion is picking the grapes and turning them into wine. The wine holds up better over time the same way a Roth balance holds up better than a traditional IRA balance with future RMDs and ordinary-income taxes attached.
But picking grapes doesn’t grow grapes. The harvest is only as strong as the vineyard. If the vineyard is being drained season after season — by something small enough to overlook — no harvesting technique will recover what was lost.
The three drags described below are the slow, quiet drains. They don’t trigger an alert. The account balance can still rise. Statements can still look healthy. The damage shows up only as a smaller pile of grapes than there should have been when conversion season arrives.
Drag #1: Hidden Fees Quietly Erode the IRA
The first drag looks small on any single statement and compounds catastrophically over a multi-decade IRA. A 1% advisory fee sounds harmless. Layered fees of 1% advisory plus another 0.5% to 1% inside the mutual funds or ETFs reach 1.5% or more in annual cost — every year, on the full balance, regardless of performance.
On a $1.5 million IRA, 1.5% in annual cost is $22,500 a year. Compounded over fifteen years of growth and withdrawals, the cumulative cost reaches into the hundreds of thousands of dollars. Every dollar of that cost is a dollar that never reached the conversion math.
Fee drag is dangerous specifically because it doesn’t trigger an alert. The account can still rise. The advisor still sends quarterly reports. Performance numbers may still look reasonable in isolation. The drag is the gap between the return that happened and the return that would have happened with a cleaner setup.
To diagnose fee drag, ask:
- What is the total dollar cost of this account this year — advisory plus fund expenses plus any platform fees?
- Are there layered costs inside the funds themselves that aren’t quoted in the advisory fee?
- Is the household paying an advisor fee on top of higher-cost mutual funds that already include their own management cost?
Total all-in cost is the only number that matters. A percentage by itself hides what the dollars actually look like.
Drag #2: Reactive Investing Breaks the Compounding Effect
The second drag looks responsible. Markets fall, the household reacts. Markets rally, the household reacts again. Funds get swapped. Allocations get shifted. Each move feels like a careful response to changing conditions.
A healthy vineyard does need care — but it also needs time. Pulling vines up to check the roots interrupts the very growth being measured. Investment behavior works the same way. Compounding requires uninterrupted exposure. Selling after a decline, sitting in cash, then re-entering after the recovery has already happened is a pattern that destroys long-term return — and it is one of the most common patterns inside otherwise well-funded IRAs.
Behavior drag is especially costly during the years just before and during a conversion sequence. A panicked move out of equities after a 20% drawdown, followed by re-entry after the rebound, can shave years of compounding off the balance the conversion strategy is supposed to optimize. The strategy is sound; the execution undermines it.
Signs of behavior drag:
- A history of selling after market declines, then re-entering after a recovery.
- An account that reflects a series of reactions rather than a stable, documented long-term plan.
- Investment decisions driven primarily by headlines, market commentary, or short-term performance.
Behavior drag isn’t about market timing skill. It is about whether a written plan exists and survives uncomfortable moments — or whether the plan gets reinvented every time the market gets uncomfortable.
Drag #3: Active Management That Doesn’t Outperform
The third drag is the hardest to spot because it sounds like expertise. A manager makes tactical shifts. Allocations get rebalanced more frequently. Sector tilts get added. Funds get swapped to “get ahead” of the next market regime. All of it sounds like skill at work.
But the relevant question isn’t how much activity is happening. It is whether that activity is producing a result the household couldn’t have obtained from a simpler, lower-cost, fully passive setup. Decades of independent research consistently show that the majority of active managers fail to outperform their benchmark over long periods, especially after fees. The activity is real. The added value often is not.
To assess manager drag:
- Is there a clear benchmark this account is compared against?
- Over five, ten, or fifteen years, has the portfolio outperformed a passive equivalent net of all costs?
- Is there a clear record of value added — or only a story about process?
If the activity inside the account doesn’t translate into measurable outperformance after costs, that activity is drag — even if it is being delivered by a credentialed manager with a confident story.
What an Optimized IRA Setup Looks Like Before Conversion
Each drag in isolation looks small. The danger is that they compound — with each other and with time. An IRA carrying all three can run for years showing positive returns and still produce a conversion outcome dramatically smaller than the household’s potential.
A Roth conversion strategy gets layered on top of an existing investment structure. The cleaner that structure, the more effective the conversions. An IRA prepared for conversion typically has three characteristics:
| Layer | What “Optimized” Looks Like |
|---|---|
| Cost | All-in annual cost known in dollars; layered fees stripped out; advisory fees only paid where measurable value is delivered |
| Behavior | Documented long-term allocation; written plan for market declines; no history of reactive shifts that interrupt compounding |
| Management | Performance benchmarked against a passive equivalent; active management retained only where net-of-cost results justify it |
The point isn’t to fire every advisor and abandon every active strategy. The point is to know what each layer is costing and what each layer is producing. A conversion plan built on top of a transparent, low-drag IRA produces materially better lifetime outcomes than the same plan built on top of a balance that has been quietly bleeding for fifteen years.
Common Mistakes to Avoid
Even households that take Roth conversion planning seriously frequently miss the investment layer underneath:
- Skipping the cost audit. Households focus on the conversion calculation and never quantify what the IRA is actually paying in total fees each year.
- Mistaking activity for value. A manager making moves is not the same as a manager beating a benchmark. Activity without measurable outperformance is drag.
- Reacting to headlines mid-conversion. A conversion sequence runs over multiple years. Panicked allocation changes during those years can undo more value than the conversions add.
- Paying twice for management. Holding higher-cost mutual funds inside an advisor relationship means paying for advice once and management twice — the most common form of layered cost in IRA accounts.

How to Audit Your Own IRA Before Conversion Planning
A useful starting point for any household considering a Roth conversion strategy is a one-page self-audit covering the three drags:
- Fee diagnosis: What did this account cost the household this year, in total dollars?
- Behavior diagnosis: Does the account reflect a steady plan or a series of reactions?
- Manager diagnosis: Has the account outperformed a passive equivalent net of all costs over a meaningful time period?
If any of those three answers is “I don’t know,” that’s the place to start before any conversion strategy gets refined.

Frequently Asked Questions
Do investment choices really affect Roth conversion outcomes?
Yes, significantly. A Roth conversion converts existing IRA wealth into tax-free wealth, but it doesn’t create new wealth. A smaller IRA balance — weakened by years of fee drag, behavior drag, or underperforming active management — produces a smaller Roth balance after conversion. The conversion math is identical; the asset base it operates on is what differs.
What is a typical “all-in” cost for an IRA, and what is reasonable?
Many households end up paying 1% to 1.5% or more per year once advisory fees, fund expense ratios, and platform costs are combined. “Reasonable” depends on what is being delivered, but the right starting point is knowing the actual dollar amount — not the percentage — and asking whether that dollar amount is producing measurable value over time.
Isn’t active management worth paying for if the manager is skilled?
Sometimes — but the standard for “skilled” is measurable outperformance net of all costs over a meaningful period (typically five to fifteen years) against a clear passive benchmark. Most active managers fail to clear that bar. Activity and credentials are not the same as outperformance after fees.
How does behavior drag affect a Roth conversion specifically?
A Roth conversion strategy runs over multiple years, often during the same period when markets test investor patience. Selling after a decline and re-entering after the recovery shaves real compounding off the balance — and that lost compounding compounds again, because the conversion itself then happens on a smaller account.
Should I fix my investment structure before starting Roth conversions?
In most cases, yes. The investment layer is the asset base; the conversion layer is the tax strategy applied to it. Running conversions on top of a high-cost, reactively managed, underperforming IRA produces materially worse results than first cleaning up the investment layer and then layering conversions on top of a stable base.
Can a low-cost passive setup work for an IRA Millionaire?
Often, very well. Lower-cost passive investing is frequently a stronger base for a long-horizon IRA than higher-cost active management — particularly for households whose primary value driver is tax strategy (Roth conversions, RMD planning, IRMAA management) rather than security selection.
How can I tell if my advisor is adding value beyond a passive portfolio?
The honest test is performance net of all costs against a passive benchmark over a long enough period to reduce noise — typically five to ten years minimum. If that data isn’t being shown, or the manager redirects the conversation to process and market commentary rather than measurable results, that itself is information.
