Permanent vs Interim vs Fractional Leadership: Which Costs Less?
None of the three models is cheaper in every situation. Each has a different cost shape, and the right comparison depends on how long the leadership is actually needed.
In short
No single model is cheapest overall — each has a different cost shape. Fractional leadership generally carries the lowest ongoing cost where full-time capacity genuinely is not needed. Interim leadership carries a higher rate but no long-term commitment, and suits a defined, time-limited situation. Permanent leadership carries the highest ongoing cost but is the only model built for continuity, and is usually the lowest cost per year once a role is genuinely full-time and ongoing.
"Which is cheapest" is the wrong first question, though it is understandably the one most businesses ask. Permanent, interim and fractional leadership have different cost shapes because they solve different problems, and comparing the headline numbers without comparing the requirement usually produces the wrong answer.
This article sets out how the three cost structures actually differ, so the comparison can be made against the right thing: the leadership requirement in front of you.
Why the three models cannot be compared on one number
A permanent salary, an interim day rate and a fractional monthly fee are structured around different things: ongoing full-time employment, a defined temporary assignment, and part-time ongoing capability respectively. Placed side by side without context, the comparison flatters whichever model has the lowest headline figure — which is rarely the useful question.
How each cost structure actually works
| Model | How it is typically costed | What it commits you to |
|---|---|---|
| Permanent | Salary, bonus and benefits, plus a success-fee recruitment cost agreed per assignment | An ongoing employment relationship, with associated employer obligations |
| Interim | A rate agreed for a defined assignment and period | A fixed period of engagement, ending when the assignment or mandate is complete |
| Fractional | A regular fee for an agreed number of days or a defined scope per month | An ongoing but part-time commitment, reviewed periodically rather than open-ended employment |
When each model tends to cost less in practice
- Fractional tends to cost least where the business genuinely needs senior judgement and direction but not full-time capacity — a smaller team, an earlier-stage business, or a function that does not yet justify a full role.
- Interim tends to cost least relative to the alternative where the requirement is short and specific — cover during a search, a defined transformation or integration — because there is no long-term commitment once the assignment ends.
- Permanent tends to cost least per year of leadership delivered where the role is genuinely ongoing and full-time, because the alternative would be paying an interim or fractional rate indefinitely for capacity that is needed indefinitely.
Where the real cost differences are hidden
- Recruitment and onboarding cost is spread differently — a permanent search carries a one-off success fee; fractional and interim arrangements are typically agreed more quickly, with lower upfront cost but ongoing fees.
- Notice periods and continuity risk differ — permanent leadership carries statutory and contractual notice obligations; interim and fractional arrangements are usually more flexible to end, which is itself worth pricing.
- The cost of getting the model wrong is asymmetric — an interim leader kept on too long can cost more than a permanent hire would have; a permanent hire made for a temporary problem creates cost and disruption when the situation changes.
How Evans Sales Consultancy prices each model
Permanent executive recruitment at Evans Sales Consultancy is a success-fee model, agreed in writing for each assignment against the seniority and difficulty of the role. Interim and fractional executive recruitment — placing an executive into a client's business on an interim or fractional basis — is also agreed per assignment; we do not publish standard day rates.
This is separate from Evans-delivered Fractional Commercial Leadership, where Evans Sales Consultancy itself provides fractional sales or commercial leadership directly to a client rather than recruiting a fractional executive on the client's behalf. That service is priced from £2,950 + VAT per month plus 2.5% commission. The distinction matters: one is a recruitment service that places someone into your business; the other is Evans acting as the fractional leader.
Current market ranges
Salary levels, interim day rates and fractional fee levels all vary by sector, seniority, geography and scope, and are reviewed periodically rather than fixed. The Evans UK Executive Salary Guide 2027 sets out how to approach current positioning for a specific role; any figure should be confirmed against the specific brief rather than assumed from a general comparison.
A practical way to decide
In our experience, the decision holds up better when it starts with the requirement rather than the budget line. Three questions tend to clarify it quickly.
- Is the need ongoing, or does it end when a specific situation is resolved?
- Does the role need a full week, or would two or three days of senior time actually cover it?
- Would the business be comfortable handing full functional authority to this person indefinitely, or is this a bridge to something else?
Senior capability without a full-time appointment?
Fractional executive leadership provides ongoing senior expertise on part of a week, where the thinking is needed but a full-time appointment is not yet justified.
