What a portfolio career looks like for an executive
A portfolio career is several roles held at once instead of one full-time job. For a UK executive that usually means fractional seats for most of the income, a non-executive board seat or two for the governance, and the occasional interim assignment between clients. Below is what each piece pays, how many days it takes, and how the three fit together.
Portfolio career meaning
The term covers anybody earning from several roles at once, which is why so much written about it is for GPs, teachers or consultants. For an executive it means something narrower: holding senior seats in more than one company at the same time, each on agreed days, rather than one seat five days a week. The income and the risk are spread across the roles, and so is the attention, which is the part that takes adjusting to.
The three pieces: fractional, interim, non-executive
Fractional. The executive seat itself, held part-time: a CFO, CMO or CTO for one to three days a week on an ongoing basis. It is where most of a portfolio's income comes from, priced by the day. How to become a fractional executive covers each seat.
Interim. Full-time cover, 5 days a week, for a defined period, usually 3 to 9 months. It pays well while it runs and displaces everything else, so in a portfolio it fills the gap after a client ends rather than sitting beside two others. Interim executives sets out when it is the right arrangement.
Non-executive. A board seat, paid a fixed annual fee for a day or a few days a month of oversight and challenge rather than running anything. The QCA non-executive director survey 2022 puts the average fee at £40,500 for small and mid-sized quoted companies, and the BDO AIM 100 remuneration report 2025 puts the median at £58,000 for the 100 largest companies on AIM. Private company fees are usually lower. Non-executive director fees has the full survey figures.
Portfolio career examples by seat
One common shape, priced for every seat: two fractional clients at a day and a half each, 3 days a week at the seat's typical rate across 46 billable weeks, plus one non-executive seat at a smaller quoted company at the QCA non-executive director survey 2022 average. Before tax and your own costs.

An interim assignment in place of the fractional clients, at the same typical rate, runs at about £22,042 a month for a CFO, for as long as it lasts.
How many days a week a portfolio really takes
Plan for three to four days of client work, not five. The rest goes on board papers, preparation for the fractional clients, the weeks between engagements and finding the next one. A board seat looks small at a day or two a month and is not, because a bad quarter or a transaction turns it into several days at no notice. Count every role in days a month before agreeing to the next one.
Moving from a full-time role into a portfolio
Most portfolios start with one fractional client, often the company being left or a founder who has seen the work, and grow a role at a time. Taking a board seat while still employed, where the employer allows it, gives the governance experience a first non-executive appointment usually asks for. Price the fractional work against what the full-time package was worth: what to charge and the salary to day rate calculator do that arithmetic, and how to become a non-executive director covers the board side.
Common questions
What is a portfolio career?
A portfolio career is holding several professional roles at once instead of one full-time job. For an executive it usually means a mix of fractional seats, interim assignments and non-executive board roles, chosen so the days, the income and the risk are spread across more than one company.
What does a portfolio career look like for an executive?
Typically two fractional clients at one to two days a week each, one or two non-executive seats at a day or two a month, and an occasional interim assignment between clients. The fractional seats carry most of the income; the board seats carry the governance experience.
How much can you earn from a portfolio career in the UK?
It depends on the seat and how many days sell. A fractional CFO at the typical £1,150 a day, three days a week across 46 weeks, bills £158,700. One non-executive seat at a smaller quoted company adds about £40,500, the average fee in the QCA non-executive director survey 2022. Private company board fees are usually lower.
How many days a week does a portfolio career take?
Most executive portfolios settle at three to four days of client work a week, with the rest spent on board preparation, the gaps between engagements and finding the next one. Planning for five days of billable work leaves no room for any of that.
Should a portfolio include an interim role?
Only between other commitments. Interim cover is full-time for a defined period, usually 3 to 9 months, so it displaces fractional clients while it runs. It suits the gap after a client ends rather than sitting alongside two others.
