Fractional CFO Pricing
How is a fractional CFO priced?
Updated August 2026
Short answer: a fixed monthly fee scoped to your business, quoted after a discovery call. No rate card, no ballpark, because the right fee depends on scope, complexity, cadence, and whether we're also running the books. Here's how we think about it, and how Rubric Financial scopes and quotes the work.
The three ways fractional CFO work gets priced
The shape of the fee follows the shape of the engagement. Rubric Financial defaults to a fixed monthly fee for ongoing work and fixed-scope pricing for defined projects, with retainer or hourly where they genuinely fit.
Fixed monthly fee
The default for an ongoing operating rhythm: monthly close review, forecast, reporting, and the CFO seat on tap between meetings. Predictable, no per-question billing, easy to budget against.
Retainer or hourly
Ad-hoc, project-shaped, or unpredictable workloads where a fixed monthly fee doesn't cleanly fit. Available where it genuinely suits the engagement.
Project / fixed-scope
A defined deliverable: a fundraise, a diligence or exit process, a financial model build, or a systems implementation. Priced to the outcome, not the clock.
What drives the fee up or down
- Complexity, entities, states, revenue model, and how clean the books are today.
- Cadence, a light monthly touch is a very different engagement from a weekly, hands-on operating role.
- Stage and stakes, active fundraising, lender reporting, or an exit process raises the scope.
- Whether the books come with it, paying a CFO to first fix the bookkeeping is the expensive way to buy both.
How Rubric Financial prices it
A fixed monthly fee scoped to your business and its complexity, quoted in writing after a discovery call, with no per-question fees and no surprise bills. Your partner replies the next business day throughout the engagement, and the work is CPA-reviewed under one roof.
Because Rubric Financial runs bookkeeping, accounting, tax, and CFO work under one roof, you're not paying a CFO to first rebuild someone else's books, the strategic work sits on a foundation we already maintain. Fee-only: our only revenue is your fee, no commissions or kickbacks.
Fractional CFO pricing, FAQs
- How is a fractional CFO priced?
- Rubric Financial works on a fixed monthly fee scoped to your business, with retainer or hourly arrangements where they genuinely suit the engagement, and no per-question fees. We don't publish a rate card or a ballpark: the number depends on the scope, the complexity, the cadence, and whether we're also running the books. After a short intro call you get a written fixed-fee proposal, quoted to your business, before you sign anything.
- What does a fractional CFO engagement include?
- It depends on what you need a CFO to own. A common shape: monthly cash-flow forecasting and runway, a review meeting on the close, budget vs. actuals, KPI dashboards, board or lender reporting, and support on the big decisions in between (pricing, hiring, financing, an acquisition, an exit). We scope it against the decisions ahead and write it into the proposal so there are no surprises.
- What drives the fee up or down?
- Complexity (entities, states, revenue model, and how clean the books are), the cadence of the engagement, the stakes (a raise or exit is more involved than steady-state reporting), and whether bookkeeping and accounting are included. Clean, current books lower the fee because the CFO isn't paying to rebuild the foundation first.
- Why won't you quote a ballpark before the call?
- Because a real number depends on the scope, and the scope depends on your business. Quoting a range without seeing the entities, the books, and the decisions ahead of you would be a guess, and guesses become the wrong anchor for both sides. A 30-minute call is enough to scope and quote a fixed fee you can hold us to.
This page describes how fractional CFO engagements are typically structured and scoped, not a quote or tax, legal, or accounting advice. Your fixed-fee proposal is quoted to your business after a discovery call.
