It is the first question almost every owner asks, and most firms dodge it. Here is a direct answer. The cost of a fractional CFO depends far less on an hourly rate than on the scope of what you actually need. Two companies the same size can pay very different amounts. One needs a monthly board package and active cash management. The other needs a one-time exit-readiness push.

The three pricing models you will see

1. Monthly retainer. A fixed fee for an ongoing scope. That usually covers board reporting, cash forecasting, lender relations, and a standing seat in your leadership meetings. This is the most common arrangement for companies that need a CFO function but not a full-time hire. You are buying capacity and continuity.

2. Project-based. A defined deliverable with a start and an end. Examples include building a 13-week cash flow model, preparing financials for a transaction, standing up a board-reporting package, or running a post-acquisition integration. You are buying an outcome.

3. Hourly or daily. Useful for short, advisory-only engagements where the work is genuinely unpredictable. It is the least common arrangement for serious operating work, because the goal is rarely more hours. The goal is a result.

What actually moves the number

  • Reporting cadence and audience. A founder who wants better visibility is a lighter scope than a PE sponsor expecting an institutional-grade board package every month.
  • The state of your books. Clean data means the CFO spends time on strategy. Messy data means the first weeks go to cleanup, and that costs more.
  • One-time complexity. A financing, an acquisition, or an exit compresses a lot of senior work into a short window.
  • How embedded you need them. Reviewing from the sidelines costs less than being in the room every week. The room is usually where the value is.

The real question: will it pay for itself?

A full-time CFO is a six-figure salary plus benefits, equity, and the risk of a bad hire. The fractional model gives you the senior judgment without that fixed cost, sized to the problem in front of you. So put the hourly rate aside for a second. The question that matters is what it costs you to keep running without this visibility. A single avoided cash crunch, a cleaner diligence process, or a few points of margin usually covers the fee several times over.
