What Is a Fractional CFO?
First published May 2026 · Last reviewed August 25, 2026
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 | $200,000–$400,000+/yr fully loaded |
| 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.
What a fractional CFO actually does
- 13-week rolling cash flow forecasting and cash management
- Monthly financial reviews and board-ready reporting
- FP&A — budgeting, scenario modeling, variance analysis
- KPI scorecards and unit-economics analysis
- Capital strategy — debt, equity, and lender relationships
- Pricing and margin engineering
- M&A support — buy-side diligence, sell-side and exit readiness
- Leadership-team integration (e.g., your EOS/Traction rhythm)
When to hire one
- Cash flow is unpredictable despite growing revenue
- You’re making big decisions on gut feel, not numbers
- You’re preparing for a loan, raise, acquisition, or exit
- You’ve outgrown your bookkeeper but can’t justify a full-time CFO
- You’ve hit a growth ceiling and need a financial strategy to break through

What does a fractional CFO cost?
At Local Fractional, fractional CFO pricing is a flat monthly retainer — no hourly billing, no “every call costs extra”:
- Fractional CFO Partnership — $5,000–$10,000+/month. Embedded executive leadership: weekly cadence, 13-week cash flow, KPI scorecards, EOS/Traction integration, capital and exit work.
- Fractional Executive Advisory — $2,500/month. A lighter, strategic-mentorship tier for businesses that already keep clean books and want one to two strategic meetings a month.
For comparison, a full-time CFO costs $200,000–$400,000+ a year fully loaded (salary, bonus, benefits and equity). See the full pricing guide.
Is a fractional CFO worth it?
It is worth it when the decisions in front of you are bigger than the retainer. A $60,000–$120,000 year of CFO time pays for itself if it prevents one bad hire, prices one large job correctly, or shows a cash shortfall early enough to fix it before payroll. Those are the decisions most $2M–$50M businesses make without a finance leader in the room.
The clearest signs it will pay back:
- You cannot say how much cash you will have in eight weeks. A 13-week cash flow forecast is usually the first thing we build, and the first thing owners keep.
- A lender, investor or buyer is asking questions your books cannot answer. That conversation goes better with someone who has sat on both sides of it.
- Revenue is growing but margin is not. Job, customer or product profitability is where the money hides.
It is not worth it yet if your books are months behind (fix bookkeeping first; a CFO cannot steer on numbers nobody trusts), or if the business is small and stable enough that a good CPA and a monthly review cover it. If the books are clean and you mainly want a sounding board, the $2,500/month Fractional Executive Advisory tier is the better fit.

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 costs $200,000–$400,000+ a year fully loaded.
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.
