A flat-fee financial advisor charges one set annual fee for advice and planning, rather than a percentage of the money they manage for you. The fee is set by how complex your finances are, not by your balance, so it stays the same as your portfolio grows. For high earners, that pricing difference can add up to six figures over time compared with the traditional 1% assets-under-management (AUM) model.
What a flat-fee financial advisor is
Most traditional advisors are paid a percentage of your assets under management, typically around 1% a year (Kitces advisory fee research). Their management fees, and their incentive, grow with your balance. A flat-fee advisor instead charges a fixed annual amount, often called a retainer or subscription, and manages no assets on a percentage basis. You keep your investment portfolios where they are, and you pay for the planning and tax work, not for the size of your account.
The four ways advisors charge
There are four common fee models. For the full breakdown with dollar examples, see how much a financial advisor costs; in brief:
| Model | How it works | Typical cost |
|---|---|---|
| AUM | A percentage of managed assets | ~1% a year (about $10,000 on $1M) |
| Flat fee | A fixed annual fee by complexity | ~$2,000 to $9,000 a year (estimate) |
| Hourly | Per hour for targeted advice | ~$200 to $400 an hour |
| One-time plan | A single upfront project fee | ~$3,000 for a standalone plan |
Flat fee vs 1% AUM: the math
The gap widens as your net worth grows. Consider a portfolio that grows from $500,000 to $1.5 million over ten years:
- Under a 1% AUM model, the annual fee climbs from about $5,000 to about $15,000.
- Under a flat fee set at $4,000, the annual fee stays $4,000.
This is illustrative, not a guaranteed outcome, but the direction is the point: an AUM fee scales with your balance while a flat fee does not, so the more you save, the more a flat fee tends to favor you.
Fee-only vs fee-based: the fiduciary question
These sound alike and are not. A fee-only advisor is paid only by you, with no commissions on products they recommend, which is the stricter fiduciary posture (NAPFA, CFP Board). A fee-based advisor can be paid by you and also earn commissions. Before hiring anyone, ask whether they are fee-only, and whether they act as a fiduciary at all times (SEC investor.gov). Most flat-fee advisors are fee-only, but confirm it.
What flat-fee advisors cost
Industry fee surveys put flat-fee planning at roughly $2,000 to $9,000 a year, set by the complexity of your situation rather than your balance (Kitces). Some charge a flat retainer; some tier the fee by complexity; some bill tax filing separately. Figures vary by firm and year, so treat these as estimates and confirm current pricing with any advisor before deciding.
Who a flat-fee advisor is best for
A flat fee tends to favor people whose balances are growing and whose finances are genuinely complex:
- High earners with equity compensation (RSUs, ISOs, NSOs) or a coming liquidity event.
- People with crypto, real estate, or business income that a percentage-of-assets advisor may not coordinate.
- Anyone whose portfolio is large enough that 1% a year is a bigger number than a flat fee.
If your situation is simple and your balance is modest, a low-cost AUM or robo-advisor can be cheaper. Compare the annual dollar cost both ways.
How to choose a flat-fee advisor
- Confirm the advisor is fee-only and a fiduciary at all times.
- Ask exactly what the flat fee includes, and whether tax planning and filing are in-house or billed separately.
- Check whether they handle your actual complexity across asset classes: equity compensation, crypto, real estate, business income.
- Compare the annual dollar cost against a 1% AUM quote at your balance, not just the headline percentage.
- Ask how they coordinate investments, taxes, and planning, or whether those are separate.

Nino is one flat-fee option, but it is not the only one. See how the main services stack up on the comparison hub, including Nino vs Facet and Nino vs Wealthfront, and the roundups of Facet alternatives and Domain Money alternatives.
Where Nino fits
Nino is a flat-fee service that pairs a dedicated CPA and CFP on one team, starting at $2,000 a year and staying flat as you grow. It plans taxes year-round with filing available, and coordinates equity, crypto, cash, and real estate in one plan. See the pricing page for what each tier includes and how a flat fee compares to 1% AUM at your balance.
