How much does a fractional CFO cost?

Hourly rates, monthly retainers and what moves them, with named sources instead of a sales pitch — plus the cheaper question to answer before you pay any of it.

Fractional CFO pricing has a reputation for opacity it mostly deserves: the people publishing the rates are the people selling the hours. So here is the market as the sellers themselves publicly list it, what moves the price, and — because it is the cheaper question — how to tell whether you need to pay it at all.

The short answer

ArrangementPublicly listed range
Hourly$175 to $450 per hour; growth-stage work typically $200 to $350
Monthly retainer, growth stage$3,000 to $10,000 per month
Monthly retainer, established company$3,000 to $12,000 per month
Full-time CFO, for comparison≈$230,000 average US salary, before benefits and equity

These figures come from rates that firms in the market publish themselves — Graphite Financial, a startup accounting firm, lists all four of the ranges above in its own pricing guidance. They are asking prices, not survey data, and the honest reading is that they mark the neighborhood rather than the house: what you will actually pay depends on the factors below. In euros, the picture translates to roughly €150 to €350 an hour and €2,000 to €12,000 a month, the ranges in our overview of what a fractional CFO does.

What moves the price

Four things, mostly.

Seniority and track record. A CFO who has taken companies through the kind of round you are raising charges at the top of the range and is often worth it precisely then — pattern recognition is the product.

Complexity. Multiple entities, multiple currencies, inventory, debt facilities, revenue recognition beyond simple subscriptions: each adds hours and pushes hourly rates up.

The state of your books. Messy or behind bookkeeping means the first weeks are cleanup at CFO rates. Getting the books current first, at bookkeeper rates, is the single most effective way to lower the bill.

Urgency. A data room that must exist in three weeks prices differently from a standing monthly cadence. Deadlines are billable.

What the money buys

At these rates, the deliverables should be strategy, not data entry: the fundraise model and the diligence support around it, the forecast and scenario work, the board packet, pricing and unit-economics analysis, and oversight of the bookkeeper and accountant you already have. If a proposal at CFO rates includes reconciling transactions or chasing invoices, you are being sold accounting at a five-fold markup — the boundary between the two jobs is drawn in what a fractional CFO actually does.

A useful sizing check before signing anything: a $5,000 monthly retainer is $60,000 a year, which is the ballpark of a part-time hire. Judge it with the same seriousness — the same runway math as any hire, where the employee cost calculator turns a cost into the months of runway it spends.

The cheaper question first

Most founders reaching for CFO pricing pages do not have a CFO-shaped problem yet. They have a visibility problem: what is my runway, what is my burn, what did MRR do, can I afford the next hire. Those questions feel like they need an expensive adult because they sit unanswered, but they are arithmetic on numbers you already have — a runway model you keep current answers them continuously, and an AI CFO grounded in your own numbers answers them on demand for about the cost of a CFO's ten minutes.

The distinction that decides it: judgment versus visibility. Raising a priced round, restructuring pricing, managing a board — judgment, hire the human. Knowing where the money is going and when it runs out — visibility, and paying $300 an hour for it is how $10,000 retainers turn into disappointment on both sides. The sequencing that works: get the visibility for nearly free, then buy judgment only when a decision that deserves it arrives — and when it does, the honest test for whether you need one is the place to start, including the engagement structures that keep the relationship worth its invoice.

Common questions

How much does a fractional CFO cost per month?

Monthly retainers mostly run $3,000 to $12,000 depending on scope and seniority — Graphite Financial, a startup accounting firm, publicly lists $3,000 to $10,000 a month for growth-stage companies and up to $12,000 for established ones. Light-touch engagements sit at the bottom of the range; hands-on work through a fundraise sits at the top.

How much does a fractional CFO charge per hour?

Published hourly rates cluster between $175 and $450, with growth-stage work typically quoted at $200 to $350 an hour. Rates scale with the CFO's track record and with complexity: multiple entities, currencies, inventory or debt all push toward the top of the range.

Is a fractional CFO worth it?

Worth it when you are buying judgment for decisions with real stakes: a priced round, board reporting, pricing strategy, complex cash management. Not worth it when what you actually need is visibility — knowing your runway, burn and MRR. Those are arithmetic, and paying CFO rates for arithmetic is the most common way these engagements disappoint.

How many hours a month do you need a fractional CFO?

A meaningful ongoing engagement is usually a few days a month — enough for a forecast update, a board packet and the conversations around them. If the honest need is under a day a month, a project engagement with a defined deliverable is a better structure than a retainer, because thin retainers drift into invoiced availability.

What is the difference between a fractional CFO and a full-time CFO in cost?

Graphite Financial puts the average US full-time CFO salary near $230,000 before benefits, equity and payroll taxes — call it $20,000 or more a month loaded. A fractional engagement at $5,000 a month buys roughly a quarter of the cost for the slice of CFO work most startups actually have, which is the entire argument for the model.
