A fractional CFO is a senior professional who provides executive-level leadership on a part-time or contract basis – typically 10-24 hours per week. They bring the strategic thinking and operational experience of a full-time C-suite hire, but work with multiple companies simultaneously rather than committing exclusively to one.
The model sits between advisors and full-time executives. Advisors give you their opinion and leave. Full-time executives own everything but cost $200K-$500K per year. Fractional CFOs occupy the middle ground: they embed into your team, own real outcomes, and maintain ongoing accountability – just not five days a week.
The fractional model works because many companies – especially those between $1M and $20M in revenue – need senior expertise but can't justify or afford a full-time executive salary. A fractional CFO lets you access that experience without the commitment.
TL;DR
Fractional CFOs embed in your team and own outcomes; consultants recommend and leave; interim CFOs work full-time temporarily as a bridge hire. The distinction matters.
Provide recommendations and leave. They analyze your situation, deliver a report or strategy, and move on. The implementation is your problem.
Embed into your team and own outcomes. They build and execute strategy with your team, adjust when things don't work, and share accountability for results.
Fill a vacant full-time role temporarily. They work 40+ hours per week, usually for 6-12 months, while you search for a permanent hire.
| Type | Time Commitment | Relationship | Accountability |
|---|---|---|---|
| Consultant | Project-based | External | Recommends |
| Fractional CFO | 10-24 hrs/week | Embedded | Owns outcomes |
| Interim CFO | Full-time temp | Temporary | Full scope |
Fractional CFOs typically charge $10,000-$20,000 per month, depending on their experience and the scope of work. The math works out to 60-70% savings compared to a full-time hire.
| Option | Cost | What You Get |
|---|---|---|
| Fractional CFO | $10K-$20K/month | 10-24 hrs/week, embedded leadership |
| Big 4 Consultant | $350-$1,000/hour | Analysis and recommendations |
| Full-Time CFO | $200K-$500K+ salary + benefits | Exclusive, 40+ hrs/week |
| Executive Coach | $300-$1,000/session | Guidance without implementation |
| MentorCruise | Starting at $300/month | Mentorship format, free trial, cancel anytime |
A $300K CFO costs your company roughly $350K-$400K when you add benefits, equity, and hiring costs. A fractional CFO at $15K/month costs $180K/year – and you can scale that up or down as needed.
Browse Fractional CFOsYou need a fractional CFO when you have a leadership gap that's holding back growth but can't yet justify a full-time hire.
The fractional model also works well during transitions – growth phases, pivots, M&A activity, or leadership changes. You get stability and expertise while you figure out what the permanent structure should look like.
You've outgrown founder-led everything but haven't scaled to the point where a $300K+ salary makes sense.
You're the de facto CEO, CFO, and head of marketing. Something is suffering – probably all three.
You're preparing for fundraising, entering a new market, or rebuilding your tech stack. These projects need senior leadership, but the need is bounded.
A fractional CFO who's scaled three companies brings pattern recognition you can't hire for at your stage.
Start by getting clear on what you actually need. "We need a fractional CFO" is less useful than "We need someone who can build our demand generation engine from scratch."
Someone who's scaled three companies from your revenue stage to 10x has directly relevant experience.
Ask what they built, what results they drove, and what didn't work. Impressive resumes don't guarantee practical help.
How do they prefer to work? How accessible will they be between scheduled time?
Start with a defined project or a few weeks of work before committing to a longer arrangement.
Hiring based on impressive resume alone without checking specific outcomes
Not clarifying scope and expectations upfront – what exactly are they responsible for?
Underestimating the time commitment needed to actually move the needle
Treating your fractional hire like a consultant – giving them projects instead of ownership

The difference between a successful fractional engagement and a frustrating one usually comes down to how you structure the relationship.
What does success look like in 90 days? What specific outcomes are you hiring them to drive?
Add them to relevant Slack channels and leadership meetings. The more context they have, the better.
A weekly 1:1 helps surface issues early and keeps the relationship tight. Don't limit interactions to formal meetings.
The best fractional relationships feel like working with a co-founder who happens to be part-time. Give them real ownership.

Consultants provide recommendations and leave. Fractional CFOs embed into your team, own outcomes, and share accountability for results. A consultant might tell you what strategy to pursue. A fractional CFO will build and execute that strategy with your team.
Consider fractional when: your revenue is $1M-$20M and you can't justify full-time C-suite salary; you need specific expertise for a defined initiative; you want to test the role before committing to a permanent hire; or you need flexibility to scale leadership up or down.
The most common fractional executive roles are CFO (financial planning and fundraising), CMO (marketing strategy and growth), CTO (technical architecture and engineering leadership), and COO (operations and scaling). Fractional CEOs are less common but exist for specific situations like founder transitions.
