What is the difference between a fractional CMO and an interim CMO?

Time and permanence run in opposite directions. An interim CMO works full time but temporarily: cover for a departure, a maternity leave, a turnaround, typically three to nine months at a day rate. A fractional CMO works part time but indefinitely: half a day to three days a week, on a rolling arrangement, as the firm's ongoing marketing leadership. Interim fills a gap in an existing function; fractional IS the function for firms not big enough to need it full time.

Is a part-time CMO the same as a fractional CMO?

Yes. Part-time CMO, fractional CMO, outsourced CMO and virtual CMO all describe the same arrangement: senior marketing leadership bought by the day rather than employed full time. Fractional is simply the name that won. The only distinction worth checking is whether the person comes alone or with a team that delivers the work.

When does an interim CMO make more sense than a fractional one?

When there is genuinely a full week of senior work and a hard end point. The classic cases: your marketing director resigned and the team of five needs leading while you recruit, or a rebrand and repositioning needs someone driving it daily for six months. If the week is not really full, you are paying interim day rates for fractional-shaped work.

What does an interim CMO cost in the UK?

£800 to £1,500 a day is the typical range, which puts a full-time month at £16,000 to £30,000. That is the price of full-week seniority on short notice, and for a genuine gap it is worth it. It is also why running an interim longer than the gap demands gets expensive quickly, and why firms without a full week of work are better served fractionally at £3,000 to £12,000 a month.

Can a fractional CMO cover an interim gap?

Sometimes, and it is worth asking. If the departed leader's week was genuinely full, no: buy interim cover. But plenty of marketing leader roles in 11-to-50-person firms were never really five days of senior work, and the departure is the moment firms discover it. Replacing a £90,000 hire with a fractional arrangement plus delivery often improves both the leadership and the output.

Which is right for a recruitment agency?

For most recruitment and search firms between £2m and £20m in fees, fractional, because the senior work is real but rarely fills a week. Interim earns its place during a specific transition, and full time makes sense once the function has grown to a team the leader must run daily, usually well past £20m. We sell the fractional shape, so test that logic against our cost guide rather than taking it on trust.

Fractional, Interim or Full-Time CMO? Which One You Actually Need

Three job titles that sound interchangeable and price completely differently. This guide separates them in plain English, puts the UK numbers side by side, and gives you a sixty-second way to work out which shape your firm actually needs.

A fractional CMO works part of the week, indefinitely. An interim CMO works all week, temporarily. A full-time CMO works all week, permanently. Two questions separate them: is the need ongoing, and does it truly fill a working week?

Founder of Limivex, fractional CMO to recruitment and search firms. Updated August 2026.

Why the titles blur together

All three do the same job when they are in the room: own the strategy, run the function, answer to the board. Sellers blur the titles further because each label carries a different price tag for similar-sounding work. An interim at £1,200 a day, an agency pitching a "virtual CMO" bolt-on and a fractional operator at £4,800 a month can all appear to be quoting for the same thing. They are not.

What actually differs is the shape of the commitment, and the wrong shape is expensive in both directions. Interim rates for an ongoing part-time need overpay badly. A part-time arrangement where a genuine full-time gap exists leaves the team leaderless four days a week. If you want the full definitions first, read what a fractional CMO is; the numbers behind every option live in the cost guide.

One Picture Instead of Four Definitions

Two Questions Separate All Four Titles

Is the need ongoing, or for a fixed period? And does it genuinely fill a working week? Answer those and the right shape falls out.

Fractional CMO

Interim CMO

A part-time CMO, an outsourced CMO and a virtual CMO all live in the top-left cell. Different names, same arrangement.
