Fractional CFO Cost

How much does a fractional CFO cost?

Short answer: most small businesses pay roughly $3,000–$10,000+ per month, or $200–$500/hour, depending on scope and cadence — a fraction of a $200K–$400K+ full-time CFO. Here's what sits behind the number, and how Rubric prices it.

The three ways fractional CFOs price

Market ranges below are directional — actual pricing varies by region, industry, and scope. They're here to calibrate expectations, not quote a number.

Hourly

~$200–$500 / hour

Ad-hoc or project work with an unpredictable workload. Simple to start, but the meter running discourages exactly the questions you should be asking your CFO.

Monthly retainer

~$3,000–$10,000+ / month

An ongoing operating rhythm — a monthly close review, forecast, and reporting. The most common structure for small businesses, and the easiest to budget against.

Project / fixed-scope

~$5,000–$50,000+ / project

A defined deliverable: a fundraise, a diligence or exit process, a financial model, or a systems build. Priced to the outcome, not the clock.

What drives the cost up or down

  • Complexity — entities, states, revenue model, and how clean the books are today.
  • Cadence — a light monthly touch costs far less than a weekly, hands-on operating role.
  • Stage & 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 prices it

A fixed monthly fee scoped to your business — no hourly meter, no per-question fees, no surprise bills. After a short intro call you get a fixed-fee proposal within 48 hours, and your partner replies within one business day throughout the engagement.

Because Rubric 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 cost — FAQs

How much does a fractional CFO cost per month?
Most small-business fractional CFO engagements land between roughly $3,000 and $10,000+ per month, depending on scope and cadence. Hourly arrangements typically run $200–$500/hour, and fixed-scope projects (a raise, a diligence process, a model build) are priced to the deliverable. Rubric works on a fixed monthly fee scoped to what you actually need.
Is a fractional CFO cheaper than a full-time CFO?
Materially. A full-time CFO in the U.S. typically costs $200,000–$400,000+ in salary plus bonus, equity, and benefits. A fractional CFO gives you the same senior judgment for the hours you actually need — often a fraction of that — which is the entire point of the model for a business that isn't ready to staff the seat full-time.
What drives the price 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 cost because the CFO isn't paying to rebuild the foundation first.
