The fractional alternative

Fractional CFO and Finance Director engagements — like those offered by EC Solution — work differently to traditional interim. Rather than a fixed day rate for a defined period, fractional arrangements are typically structured as a monthly retainer based on a committed number of days per month. This gives businesses predictable costs and genuine continuity.

Day rate FAQs

What's the difference between a day rate and a fractional retainer?

A day rate is typically used for traditional interim assignments — the professional charges a fixed amount per day worked. A fractional retainer is a monthly arrangement for an agreed number of days, providing more predictability for both parties. Fractional work is usually longer-term and more embedded than a classic interim engagement.

Do interim day rates include VAT?

Day rates are almost always quoted exclusive of VAT. If the interim is VAT-registered (required above £90,000 annual revenue), 20% VAT will be added on top of the day rate and is reclaimable by your business if you are also VAT-registered.

Do I pay more if I use a recruiter?

Yes. Recruitment agencies typically charge 15–25% on top of the interim's own rate, adding significant cost — particularly for longer assignments. Going direct to a fractional CFO practice like EC Solution means you pay the practitioner's rate with no agency markup.

How do I know what rate to set as a finance professional?

The standard starting point is to take your equivalent permanent salary, multiply by 1.4–1.5 (to account for employer on-costs you now absorb yourself), and divide by 220 working days. The calculator above does this for you. Your actual achievable rate will also be shaped by your niche, sector experience, reputation, and demand at the point of going to market.
