Retirement & Tax Planning Answers
Comparing Flat-Fee Financial Planning Models for Retirement
Quick answer
Three flat-fee models are common in retirement planning: a one-time project fee for a single written plan with no ongoing relationship, typically a few thousand dollars; an annual flat retainer, often $5,000 to $15,000 depending on complexity, that includes ongoing planning, reviews, and access throughout the year; and a hybrid model that layers a flat planning fee on top of a separate, smaller percentage-based fee for investment management. Each fits a different need. A one-time plan suits someone who wants a single roadmap and is comfortable executing and monitoring it themselves. An annual retainer suits someone who wants ongoing tax and planning support as circumstances change. The hybrid model suits someone who wants investment management included but still wants planning priced separately from the portfolio balance.
A one-time flat project fee buys a single deliverable: a written financial plan covering retirement readiness, a withdrawal strategy, and often an initial tax analysis. It's typically the least expensive flat-fee option, and it works well for someone who wants a clear roadmap and is willing to implement and monitor it on their own going forward. The tradeoff is that the plan is a snapshot. It doesn't get updated as tax law, income, or markets change unless the client pays for another project.
An annual flat retainer is the more common model for people who want an actual ongoing relationship. The fee, often in the $5,000 to $15,000 range depending on household complexity rather than portfolio size, covers a living plan: annual Roth conversion updates, IRMAA monitoring, withdrawal sequencing adjustments, and regular review meetings. This model suits most people within a few years of retirement or already retired, since retirement tax strategy specifically benefits from year-over-year attention rather than a one-time document.
A hybrid model combines a flat planning fee with a separate, usually reduced, percentage-based investment management fee, for example 0.25% to 0.5% instead of the more typical 1%. This suits someone who wants professional investment management included but doesn't want the planning itself priced off their account balance. It's worth confirming exactly which services fall under the flat portion versus the percentage portion, since firms split this differently.
Across all three models, the number that should drive the comparison isn't the sticker price of the fee, it's the total cost relative to what a percentage-of-assets model would charge on the same portfolio, and the scope of what's actually included. A $10,000 annual retainer that includes comprehensive tax planning is a different value than a $10,000 one-time plan with no ongoing support, even though the number looks the same.
Match the model to how involved you want to be. If you're comfortable being your own ongoing plan manager, a one-time project fee may be enough. If you want someone actively watching Roth conversion windows and IRMAA thresholds every year, an annual retainer is the right structure.
When comparing quotes across firms, normalize by scope before comparing by price. Ask each firm to list, in writing, exactly what's included in the fee, then compare those lists side by side rather than comparing the dollar figures alone.
- Comparing a one-time project fee to an annual retainer as if they're the same kind of purchase. They aren't, and the cheaper number often buys meaningfully less.
- Not asking what happens after year one under an annual retainer, since some firms reduce service in later years while keeping the fee the same.
- Assuming a hybrid model's reduced percentage fee eliminates the AUM conflict discussed elsewhere. A smaller percentage is still a percentage, and the incentive it creates doesn't disappear, it just shrinks.
