- Monthly retainers typically run $4,000–$15,000, depending on scope, revenue size and the seniority of the CFO assigned.
- Hourly rates range from $250–$500; day rates for project or interim work sit at $1,500–$2,500 per day.
- A full-time CFO costs $280,000–$450,000 loaded (salary plus benefits, equity and payroll tax) — three to five times a fractional retainer at comparable revenue bands.
- Scope drives price more than hours. Strategic-only mandates (board prep, fundraising, exit) cost more than pure FP&A support.
- Specialist firms charge a premium that pays off — a generalist at $6K/month who misreads your inventory cycle or trade-spend waterfall costs more in bad decisions than the spread.
The most common question founders ask before their first fractional CFO search is a simple one: what is this going to cost? The answer depends on three things — the scope of work, the seniority of the person, and whether you are hiring a specialist or a generalist. This guide breaks down the 2026 market rates across every engagement model so you can benchmark before you negotiate.
Monthly retainer: the most common model
Most fractional CFO firms operate on a fixed monthly retainer. The market range in 2026 runs from roughly $4,000 to $15,000 per month, with the bulk of engagements sitting between $5,000 and $10,000. Where your number lands inside that band depends on four things:
- Revenue size. A $3M Shopify brand needs monthly reporting and cash-flow visibility. A $60M omni-channel CPG brand needs channel-margin analysis, working-capital modeling, inventory financing oversight and board prep. Those are different jobs.
- Scope and deliverables. FP&A and reporting support commands a lower rate than a full strategic mandate covering fundraising, lender relationships and M&A readiness.
- Seniority and specialisation. A former Big 4 partner with a consumer-brand background charges more than a general practitioner who has never modeled trade spend or DTC unit economics.
- Team model vs solo contractor. Partner-led firms with a bench of analysts and controllers — like Eightx, which runs a 12-person finance team behind each CFO — cost more per month but deliver more output than a solo operator who can only bill their own hours.
Hourly and day rates
Project-based or interim engagements often price by the day or hour. The 2026 market looks like this:
| Model | Typical rate | Best for |
|---|---|---|
| Hourly | $250–$500/hr | Short advisory projects, QoE support, ad hoc analysis |
| Day rate | $1,500–$2,500/day | Interim cover, due diligence, management presentations |
| Monthly retainer | $4,000–$15,000/mo | Ongoing fractional engagement (most common) |
| Project fixed fee | $8,000–$40,000 | Defined deliverables: three-statement model, fundraising deck, QoE |
How that compares to a full-time CFO
A full-time CFO at a $20M–$100M company draws a base salary of $200,000–$350,000. Add employer payroll tax, health benefits, 401(k) match and the equity package (commonly 0.5%–1.5% for an early-stage hire) and the loaded cost lands at $280,000–$450,000 per year, or $23,000–$37,500 per month.
At a $10,000 fractional retainer you are getting roughly 25–30 cents of CFO cost for every dollar a full-time hire would cost — and you are not carrying the overhead, the notice period risk, or the equity dilution. The trade-off is time: a fractional CFO is not in your Slack all day, and surge work (closing a round, running a QoE) usually comes at project fees on top of the retainer.
What drives the premium for specialist firms
The cheapest fractional CFO option is rarely the lowest-cost option once you factor in decisions made on bad analysis. A generalist who has never seen a CPG gross-to-net waterfall, modeled DTC contribution margin layers, or navigated a retailer's deduction reconciliation can produce financial models that look complete but mislead every decision downstream — inventory buys, fundraising conversations, price increases.
Specialist consumer-brand firms like Eightx (35+ active clients, $650M+ in client revenue managed) price at the mid-to-high end of the retainer range because the mandate is genuinely different: partner-led, backed by a full finance team, running the same benchmark playbook across dozens of brands in real time. For capital-intensive or M&A-heavy situations, Putra & Co brings a senior-partner-only model built around transactions and due diligence.
How to scope before you price
Before you start conversations with firms, answer three questions: (1) What decisions am I trying to make better — cash-flow visibility, fundraising readiness, exit prep, or all three? (2) What does my current finance team look like — do I have a controller, a bookkeeper, nothing? (3) What is my revenue and what is the complexity — single channel, multi-channel, inventory-heavy, SaaS-recurring? Your answers map almost directly to a scope, and the scope maps to a price band.
