What a fractional CHRO does
A fractional chief human resources officer sits at the leadership table a few hours a week and owns the decisions that shape how people are hired, paid, developed, and managed. That is different from an HR coordinator who runs payroll forms and onboarding paperwork.
Typical work in the first year includes a compensation structure with bands and levels, a plan for hiring the next layer of managers, a performance review cycle that managers will actually use, an org design for the next stage of growth, and a calm, documented way to handle terminations and employee complaints. The CHRO also coaches the CEO on people decisions and reports to the board or owners on turnover, hiring pace, and pay risk.
Signs your company needs a fractional CHRO
Most companies hire one when people problems begin to cost real money. These are the situations leaders describe most often.
- You have 40 to 400 employees and an HR manager who is stretched between compliance and strategy.
- Pay is set one offer at a time, and employees with the same job earn very different amounts.
- Two or three managers are underperforming and nobody owns the conversation.
- You plan to double headcount in the next 12 months and have no recruiting process.
- A merger, a layoff, or a new location needs careful handling.
- Investors or a lender have asked for an org plan or a compensation philosophy.
If the need is only a handbook, a few policies, and a hiring process, a fractional HR consultant costs less and fits better.

Fractional CHRO vs fractional HR consultant vs full time CHRO
The three options solve different problems, and the right pick depends on whether you need strategy, execution, or daily presence.
| Option | Typical cost | Best for | Watch out for |
|---|---|---|---|
| Fractional CHRO | $2,900 to $12,300 a month at 6 to 15 hours a week | Pay structure, org design, leadership hiring, board reporting | Needs an HR generalist or manager to run daily tasks |
| Fractional HR consultant | $1,900 to $6,600 a month at 4 to 8 hours a week | Policies, handbook, hiring process, employee relations | Less strategic scope than a CHRO |
| Full time CHRO | Salary, bonus, equity, and benefits, typically a large six figure package | Companies above roughly 500 employees | Cost and recruiting time before the need is proven |
Many companies start with a consultant, then move to a CHRO when headcount passes 75 to 100 and managers need an owner for people strategy.

What the first 90 days look like
Month one maps the current state
The CHRO reviews pay data, org charts, open roles, turnover, policies, and any open employee issues. They interview the leadership team and a sample of managers, then write a short list of the three or four people risks that matter most.
Month two fixes the highest risks
Work usually starts with compensation bands, a hiring scorecard for leaders, and a performance review process. Any open employee relations matter gets a documented plan.
Month three sets the operating rhythm
The CHRO presents a people plan for the next four quarters, agrees on a few measures such as time to hire, regretted turnover, and offer acceptance, and sets a monthly report to the CEO or board.
