Fractional CFO vs Full-Time CFO: Cost & When to Choose

Q: Is a fractional CFO cheaper than a full-time CFO?

Substantially. A full-time CFO costs $250,000-$400,000 in base plus equity and benefits. A fractional CFO costs $24,000-$180,000 per year with no equity grant. For most companies under ~$15M in revenue, fractional delivers the same strategic judgment at a fraction of the cost.

Q: When should I hire a full-time CFO instead of fractional?

When CFO-level work fills a full week — typically at $15M+ in revenue, approaching a major transaction, or preparing for an IPO — and you want a single owner embedded full-time building a finance team. Below that, most companies only have 10-15 hours a week of real CFO work.

Q: Can a fractional CFO become full-time?

Sometimes, but more commonly the fractional CFO helps scope and hire the full-time successor and hands off the infrastructure they built. Many companies run fractional for 1-3 years, then graduate to full-time when the stage justifies the salary and equity.

Q: Does a fractional CFO get equity?

Usually not. Fractional CFOs work on a cash retainer without an equity grant, which is part of why they're cheaper than a full-time CFO who typically receives 0.5%-2% equity. Occasionally a long-term fractional engagement includes a small advisory equity grant, but it's the exception.

Fractional CFO vs Full-Time CFO: The Real Math

Last updated June 13, 2026

A full-time CFO costs $250,000-$400,000 in base plus equity and benefits. A fractional CFO costs $24,000-$180,000 per year for part-time strategic finance. For most companies under ~$15M revenue, fractional delivers the same judgment at a fraction of the cost.

The real cost comparison

The fractional-vs-full-time question is really a question of how much CFO you need, and whether you can justify a full week of it.

	Fractional CFO	Full-time CFO
Annual cost	$24,000-$180,000	$250,000-$400,000 + equity
Equity	None	0.5%-2% typical
Hours	10-20/week	Full-time
Time to hire	1-3 weeks	2-4 months
Best for	<$15M revenue	$15M+ or pre-IPO

When fractional wins

Below roughly $15M in revenue, most companies don't have 40 hours a week of CFO-level work. They have 10-15: a monthly close to oversee, a board deck, a forecast, a fundraise to support. Paying $300,000 plus equity for that is overbuying. A fractional CFO gives you the same strategic judgment for $50,000-$100,000 a year and starts in weeks, not months.

When full-time wins

At $15M+ revenue, approaching a major transaction, or preparing for an IPO, the work fills a week and then some — and you want a single owner in the building full-time, deeply embedded, building a finance team. At that point the equity grant and the salary are justified by the scope. A fractional CFO can even help you scope and hire that full-time successor.

The transition path

Many companies run a fractional CFO for 1-3 years, then graduate to full-time when the work and the stage justify it. The fractional CFO often builds the financial infrastructure, the reporting cadence, and the model that the full-time hire inherits — so the money spent fractionally isn't a detour, it's the foundation.
