What Is a Fractional CFO?
TL;DR: A fractional CFO is a senior finance executive who works with your business part-time, on an ongoing basis, providing the strategic financial leadership of a full-time CFO at a fraction of the cost and hours. It is different from an interim CFO, which is a temporary, full-time placement that fills a specific gap until a permanent hire is made. A fractional CFO is a permanent, part-time partnership; an interim CFO is a temporary, full-time placeholder. At Local Fractional, the Fractional CFO Partnership is a flat $5,000–$10,000/month retainer.
A fractional CFO is a senior financial executive who works with your business part-time, on an ongoing basis — giving you the strategic financial leadership of a full-time CFO at a fraction of the cost and time commitment. Most businesses engage one between $2M and $50M in revenue, when financial complexity outgrows a bookkeeper or controller but a full-time CFO isn’t yet justified.
In one sentence
A fractional CFO gives you a real chief financial officer — cash flow strategy, forecasting, board-ready reporting, capital and exit work — for the slice of their time your business actually needs, on a flat monthly retainer instead of a six-figure salary.
The word “fractional” describes the time commitment, not the seniority. A fractional CFO is a fully experienced executive — often a former full-time CFO or, in our case, a former investment banker — who splits their week across a small number of companies. You get the same caliber of judgment a Fortune 500 CFO brings, scaled to a growth-stage business and priced accordingly.
Where this trips people up is the difference between fractional and interim — a question we hear from prospects almost every week. They sound similar but solve opposite problems.
Fractional vs. Interim vs. Outsourced vs. Full-Time CFO
All four give you CFO-level expertise. They differ on two axes that matter: how much time (full vs. part) and for how long (permanent vs. temporary).
| Fractional CFO | Interim CFO | Outsourced CFO | Full-Time CFO | |
|---|---|---|---|---|
| Time commitment | Part-time, scaled to need | Usually full-time | Part-time / as-a-service | Full-time |
| Duration | Ongoing / open-ended | Temporary — ends when the gap is filled | Ongoing | Permanent |
| Solves for | You need ongoing CFO leadership but not 40 hours of it | A sudden vacancy, a transaction, or a turnaround — a gap to cover now | You want CFO deliverables handled by an outside firm | Finance is complex enough to need a dedicated executive |
| Typical cost | $5,000–$10,000/mo flat retainer | Day-rate or high monthly; often $15,000–$30,000+/mo | Varies; productized monthly fee | $180,000–$300,000+/yr salary alone |
| Best for | $2M–$50M businesses scaling past their bookkeeper/controller | Companies mid-transition or between permanent CFOs | Businesses wanting finance off their plate | ~$50M+ revenue or IPO/complex M&A |
Fractional vs. interim: the distinction that matters
Here is the cleanest way to hold the difference: a fractional CFO is permanent but part-time; an interim CFO is full-time but temporary.
You hire an interim CFO when a seat suddenly needs a body in it — your CFO quit, you’re mid-acquisition, or you’re in a turnaround — and you need senior coverage full-time until you make a permanent hire. It’s a bridge. It ends.
You engage a fractional CFO when you don’t need (or can’t justify) a full-time CFO at all — you need ongoing executive financial leadership for, say, a day a week, indefinitely. The same person stays with you as you grow, dialing their time up for a capital raise or an exit and back down when things are steady. It’s a partnership, not a placeholder.
Plenty of businesses start with a fractional CFO and never need anything else. Some use a fractional CFO and graduate to a full-time hire at $50M+. And occasionally an interim need (a transaction) turns into an ongoing fractional relationship once the dust settles. At Local Fractional, we run as an embedded fractional partner — see how our Fractional CFO Partnership works.

When to hire one
- Cash flow is unpredictable despite growing revenue
- You’re making big decisions on gut feel, not numbers

Frequently asked questions
Is a fractional CFO the same as an interim CFO?
No. A fractional CFO is an ongoing, part-time partnership with no end date — the same executive stays with you indefinitely and scales their time to your needs. An interim CFO is a temporary, usually full-time placement that fills a specific gap (a sudden departure, a transaction, a turnaround) and ends once a permanent CFO is hired. Fractional is permanent-but-part-time; interim is full-time-but-temporary.
How is a fractional CFO different from an outsourced CFO?
The terms overlap heavily. “Outsourced CFO” emphasizes that the work is done by an external firm, often as a productized monthly deliverable. “Fractional CFO” emphasizes shared, part-time executive time embedded in your leadership team. At Local Fractional we operate as an embedded fractional partner — in your leadership meetings and accountable for outcomes — not an arm’s-length vendor. See fractional vs. outsourced vs. virtual CFO.
How much does a fractional CFO cost?
At Local Fractional, the Fractional CFO Partnership is a flat $5,000–$10,000/month retainer for embedded executive leadership. A lighter Fractional Executive Advisory tier is $2,500/month for businesses with clean books that want strategic mentorship rather than embedded execution. A comparable full-time CFO in Dallas-Fort Worth costs $180,000–$300,000+ in salary alone.
When should a business hire a fractional CFO?
The most common triggers: cash flow is unpredictable despite growing revenue; you’re preparing for a loan, raise, acquisition, or exit; you’ve outgrown your bookkeeper but can’t justify a full-time CFO; or you’ve hit a growth ceiling and need financial strategy to break through. Most businesses engage one between $2M and $50M in revenue.
