Part-time CFO: how it works, who it is for, and what it costs (US)

A part-time CFO gives a US business senior financial leadership a few days a month, without a full-time salary. Here is how it works, who it suits and how much it costs.

What is a part-time CFO?

A part-time (or fractional) CFO works for your company on a recurring basis, handling reporting, cash flow, budgeting and banking. Unlike an interim CFO covering a temporary gap, the part-time model is built to last.

Who it suits

Growing small and mid-sized businesses that need permanent senior finance leadership but not a full-time post — you get a level of seniority your full-time budget could not afford.

What does it cost?

Day rates run $1,000 to $2,500 in 2026. At a few days a month, expect roughly $5,000 to $15,000 per month — well below a full-time hire. See our cost guide.

Frequently asked questions

How often does a part-time CFO work?

Often a few days a month for a small business, adjustable by period.

Can I start small and scale up?

Yes — start light and increase as the business grows.
