Fractional vs interim vs part-time CFO: which one to choose? (US)

Fractional CFO, interim CFO, part-time CFO: three ways to access senior finance leadership without a full-time hire — for different needs. This comparison helps you choose.

The three models at a glance

• Part-time / fractional — permanent and light: a few days a month, ongoing.
• Interim — temporary and intensive: a 3 to 12 month full-time engagement for a specific situation.
• Outsourced — the umbrella term for not bringing the role in-house.

How to choose

Growing and finance is now critical → fractional. A gap to cover or a deal to run → interim. Want to test before hiring → start fractional.

And the cost?

All three are priced on a day rate ($1,000 to $2,500 in 2026). See the cost guide.
