In-House Hire vs. Fractional CMO Matrix
Compare the true loaded cost of a full-time CMO against a fractional one.
A fractional CMO runs about $223,000 (67%) less per year, plus you skip the $95,333 ramp and the equity. Best when you need senior strategy, not a full team lead.
This compares cost, not scope. A fractional CMO sets strategy and direction; a full-time hire also owns day-to-day execution and team management.
About this calculator
A full-time CMO's job posting shows a salary figure, but that's never the real annual cost, benefits, payroll overhead, recruiting fees, and months of ramp before the hire delivers anything all add up. This calculator puts the fully-loaded in-house cost side by side with a fractional retainer, so the comparison is dollars against dollars, not a salary number against a monthly invoice.
How to use it
- Under Full-time CMO, enter base salary, a benefits/overhead percentage (payroll tax, benefits, tools, workspace), recruiting or search cost, and expected ramp time to impact.
- Under Fractional CMO, enter the monthly retainer for a senior fractional operator.
- Read in-house loaded cost per year against fractional cost per year, and the annual dollar difference.
- Check the separate ramp cost figure, the salary paid out during the months before a full-time hire is expected to actually move the business.
Methodology
In-house annual cost is base salary × (1 + benefits/overhead percentage), plus one-time recruiting cost. The overhead percentage should reflect payroll tax, benefits, tools, and any other loaded cost beyond raw salary, 25-35% is a common range.
Fractional annual cost is simply the monthly retainer × 12.
The annual difference is in-house cost minus fractional cost. A positive figure means fractional runs cheaper; a negative figure means the full-time hire, despite the higher sticker cost, works out less expensive once weighed against whatever it's being compared against.
Ramp cost is calculated separately: monthly loaded salary × the number of months you expect before the hire delivers impact. This is money spent before any return starts, and it's a cost unique to the in-house path, a fractional CMO with existing experience typically starts contributing faster.
This model compares cost only, not scope or depth of ownership. A fractional CMO typically sets strategy and direction; a full-time hire also owns day-to-day execution, team management, and being physically present for the org. Cheaper isn't automatically better, it depends on what stage of ownership the business actually needs.
FAQ
25-35% of base salary is typical in the US once payroll tax, health benefits, and standard tooling are included, higher if you're including equity value or a larger stipend package. Adjust for your specific benefits structure and location.
It's both, and this calculator treats it as a real cost because it is one: you're paying full loaded salary during those months while getting little to no strategic output in return. A 4-month ramp on a $220K salary is roughly $73K spent before any measurable impact, money a fractional engagement typically doesn't require you to spend the same way.
Once the company needs daily, in-the-building leadership: managing a growing marketing team, sitting in every cross-functional meeting, and owning execution details a part-time operator can't reasonably cover. Below that threshold, fractional buys similar seniority and strategic judgment at a fraction of the annual cost.
No, the monthly retainer entered is treated as the full cost, fractional engagements are typically structured as a flat fee with no additional payroll tax, benefits, or recruiting cost layered on top, which is part of why the comparison tends to favor fractional on pure cost.
