The short answer
What an interim CFO costs depends on experience, scope, duration and task. Billing is usually per day. The total budget matters more than the day rate: an interim CFO is only in the house on the days you need and causes none of the ancillary costs of a permanent hire. Concrete numbers only come after a conversation about your situation. Here you can see which factors drive the price and how to compare offers.
What determines the price
- Experience and industry: someone who has already guided funding rounds, sales processes or restructurings in your industry costs more than a generalist. That often saves time and mistakes.
- Scope: one day a week is different from four. With more days, the price per day often drops.
- Duration: short engagements for a clear goal are cheaper than open-ended mandates. Longer terms can often be negotiated better.
- Task: pure reporting is a different role from fundraising, exit preparation or crisis leadership. The more responsibility, the higher the price.
- Urgency: if you have to start tomorrow, you have less choice and less room to negotiate.
- Brokerage: if the search runs through an agency, its margin is added. Direct engagement or a provider with its own pool can be cheaper.
How billing works
Day rate
The classic: you pay for the days actually worked. This is transparent and flexible. Agree on a frame, such as days per week and a cap, so the budget stays predictable.
Flat fee per month or project
For clearly defined tasks, for example building a reporting setup, a fixed price is possible. It gives planning certainty but requires a precisely described scope.
Success-based shares
For financing or sales processes, success shares are sometimes common. Have it explained exactly what they are paid for and what they mean for the total price.
Interim CFO or permanent hire: a worked example
The numbers are freely chosen and for illustration only. Besides salary, a permanent CFO causes costs for social contributions, vacation, sick leave, bonus, recruiting and equipment. Assume total costs of EUR 185,000 per year. An interim CFO working 2 days per week for 40 weeks at an assumed day rate of EUR 1,200 costs 2 times 40 times 1,200, so EUR 96,000. In return you get experience exactly when you need it, without a permanent commitment. If your company needs a full-time position permanently, the permanent hire pays off.

How to compare offers
- Check the scope: what is included, what is not? A low day rate with a narrow scope can end up more expensive.
- Results instead of hours: define what should exist after the term, for example a month-end close within a set time or a finished plan.
- References: ask for comparable engagements and what remained afterwards.
- Travel and ancillary costs: clarify in advance whether they are charged separately.
- Termination and term: an engagement should be adjustable if needed.
What to clarify in advance
The clearer your goal, the more precise the offer. Helpful are: the current state of the finance function, the main tasks for the next months, the time frame and whether you need a person with leadership responsibility or a specialist for reporting. For the latter, an interim controller is sometimes enough. Our offering for the leadership level is on the Interim CFO page, a variant with a fixed scope under Finance as a Service.
Frequently asked questions
What does an interim CFO cost per day?
The day rate depends on experience, industry, task and scope. A serious number only comes after a conversation about goal and scope. Be careful with offers that name a price without asking questions.
Is an interim CFO cheaper than a permanent CFO?
For limited or part-time needs, usually yes, because you only pay for the days you need and carry no ancillary costs. For a permanent full-time need, the permanent hire can be cheaper.
How many days per week make sense?
That depends on the task. For reporting and planning, one to two days per week are often enough; for fundraising or crises, at times more.
How long does an interim CFO engagement last?
Typically a few months. Short engagements suit clearly limited goals such as a funding round, longer ones the build-up of the finance function or bridging a vacancy.
