Part-Time CFO vs Full-Time CFO: What Makes More Sense for Your Business?
For the vast majority of businesses under $30M in revenue, a full-time CFO is the wrong answer. Not because CFO-level thinking isn't valuable, it absolutely is, but because you're paying for 2,000 hours of capacity when you need 150 to 200 hours of serious financial work per year.
That's not a cost-cutting argument. It's a structural one. The businesses that figure this out stop overpaying for a title and start getting better financial leadership for less.
What a Full-Time CFO Actually Costs
A full-time CFO in Canada runs $180,000 to $280,000 in base salary. Add benefits, bonus, and executive overhead and you're at $220,000 to $350,000 annually, fixed, regardless of output. In Toronto or Vancouver, expect the higher end.
That cost makes sense when your finance function is complex enough to require full-time leadership at the executive level. Businesses at $5M, $10M, even $20M in revenue rarely meet that bar. They're paying for presence, not proportional value.
What Fractional CFO Services Actually Deliver
Fractional CFO services are built around a straightforward insight: a great CFO working 15 to 25 hours per month delivers the vast majority of the value of a full-time hire, at 15 to 20% of the annual cost.
In a typical engagement, that covers:
• Monthly close review and management reporting
• Rolling cash flow forecasting
• Financial model maintenance and scenario analysis
• Board and investor reporting packages
• Strategic finance input on pricing, hiring, and capital allocation
• Lender and investor relationship support
What it doesn't cover is work that doesn't need CFO-level judgment: bookkeeping, payroll, basic AP/AR. Those stay with your existing team, where they belong.
The Numbers, Side by Side
Take a $10M revenue business as a reference point:
• Full-time CFO: $260,000 per year, whether the capacity is used fully or not
• Fractional CFO engagement: $50,000 to $80,000 per year for senior financial leadership applied where it matters
The gap, $160,000 to $200,000 annually, is not a rounding error. That's capital available for growth, hiring, or operations. And unlike a full-time hire, a fractional engagement scales. Need more support through a financing round? Scope up. Quieter quarter? Pull back. A full-time CFO salary runs either way.
When Full-Time Is the Right Answer
There are legitimate scenarios where a full-time CFO is warranted:
• Pre-IPO with active capital markets requirements for a full-time CFO
• Complex multi-entity, multi-currency operations at significant scale that justifies the cost of a full-time resource
• Board or investor requirement for a named full-time CFO
• Finance function large enough to require full-time leadership of a team
Outside these scenarios, a full-time CFO hire is often about optics, not operational need.
The Transition Conversation
A fractional CFO arrangement isn't designed to be permanent. The right partner tells you honestly when the model has run its course, when your business has scaled to the point where a full-time hire is the logical next step, and helps you recruit and onboard that person.
That's what a good advisory relationship looks like. Not a retainer that renews indefinitely.
Frequently Asked Questions
At what revenue should a business consider a full-time CFO?
Generally, $30M to $50M, or when the finance function requires full-time leadership of a team. Below that level, the math almost never supports a full-time hire.
Can a fractional CFO lead a financing round?
Yes, this is one of the highest-value applications. Financial preparation, investor narrative, due diligence management, a fractional CFO can run the entire process. Many deals close without a full-time CFO on the org chart.
Can a fractional CFO hold the formal CFO title and sign documents?
Yes. Where required, a fractional CFO can hold the title formally and sign off on financial documents. The scope of formal authority is defined in the engagement agreement.
How do I know if my current setup is sufficient?
If you're making significant decisions without a financial model behind them, or your reporting doesn't tell you what's actually happening in the business, the current setup isn't sufficient, regardless of how many people are nominally in the finance function.
Paying full-time CFO rates for part-time output is a common and expensive mistake. If you want to know what the right financial structure looks like for your business at its current stage, book a call with Black Maple. Bring your numbers.
