What fractional HR costs, and what actually moves the number

Fractional HR is priced almost always as a monthly retainer for a defined number of hours or days. What changes between providers is who is doing the work, and that single variable explains most of the spread.

The first tier is a fractional HR consultant or generalist: typically a few thousand dollars a month for eight to sixteen hours, good for policy libraries, onboarding systems and day to day employee relations. The second tier is a senior HR director, usually three to six thousand dollars a month for around twenty hours, with the judgement to handle restructuring and manager performance. The third tier is a fractional CHRO or chief people officer: six to ten thousand dollars a month for two to three days a week, sitting in leadership and board conversations.

If a quote falls far outside those bands in either direction, the useful question is not whether it is a bargain. It is which tier of person is actually behind the invoice.

Hourly billing is transparent on paper and expensive in practice. Senior HR work is judgement work: the value sits in the decision, not the meeting minutes, and hourly billing quietly rewards long meetings.

Retainers buy capacity. You are renting a slice of a senior person's month, and the healthy version of that agreement includes a fixed number of days, a quarterly roadmap, and a clear rule for what happens when the month runs hot.

Fixed scope buys an outcome. A diagnostic, a handbook rebuild, a compensation review. It is the right structure when the work is genuinely bounded, and the wrong one when you are trying to buy ongoing leadership through a series of change orders.

The most reliable arrangement is a fixed-fee diagnostic first, then a retainer sized to what the diagnostic found. You learn the real workload before you commit to a monthly number.

Six things move a fractional quote, and only one of them is hours.

A junior fractional provider looks like a 40% saving until the first termination. Employment disputes are where HR spend is either an insurance premium or a liability, and the difference is who reviewed the documentation before it was signed.

The second hidden cost is rework. A policy library written without regard to your province, headcount and payroll setup will be rewritten within a year, usually by someone more senior, at a higher rate. Cheap policy work is the most expensive kind when it has to be redone after a claim.

The third is drift. Without a senior owner, HR decisions get made by whoever is closest to the problem, which is how companies end up with three different performance processes and no defensible record of any of them.

The comparison that matters is not salary versus retainer. It is the fully loaded cost of a senior hire against the actual volume of senior work.

A full-time CHRO carries base salary in the mid two hundreds of thousands in most North American markets, before bonus, equity, benefits and the coordinator they will ask for in month three. A fractional CHRO at two days a week is a fraction of that and can be paused when the workload falls.

The honest case for full-time is continuity. Past roughly 200 to 400 employees, depending on how distributed and how regulated you are, senior HR demand stops being spiky and becomes a daily operating need. Below that line, you are usually buying availability you will not use every week.

We start with a fixed-fee Strategic HR Diagnosis at $1,750: six hours of structured work, a document audit, and a costed 90-day roadmap. It exists so that nobody has to buy a retainer on a guess.

Fractional leadership then runs either as a 60-minute executive session from $100, or as a retainer scoped to the roadmap the diagnosis produced. Everything else in the catalogue, from employer brand to payroll technology, is priced as a defined project.

If you want a number before you speak to anyone, the diagnostic is the honest one. If you want a range, bring your headcount, your provinces or states, and the three people problems keeping you up at night, and the range becomes a quote in a single conversation.
