The definitive 2026 pricing reference for fractional CMO, CRO, CFO, COO, CHRO, and CTO engagements. Retainer ranges, hourly rates, what drives the number up and down, and how each role stacks against the full-time alternative. Decision-ready and citable.
Most B2B mid-market fractional executive engagements run $8,000 to $25,000 per month for one to two days per week, billed as a flat retainer. The COO and CHRO ranges nudge slightly higher because the mandates are broader. Hourly engagements run $200 to $450 per hour depending on role and seniority. A fractional executive costs 25 to 50 percent of the full-time equivalent while giving you senior judgment in week one instead of month four.
Side-by-side, all six fractional executive roles. Retainer ranges assume one to two days per week (8 to 20 hours), billed as a flat monthly fee. Hourly ranges are for senior independent operators; firms charge higher blended rates.
| Role | Monthly retainer | Hourly | Full-time equivalent (all-in) | Sweet spot |
|---|---|---|---|---|
| Fractional CMO | $8K to $25K | $200 to $400 | $300K to $500K / yr | $5M to $50M B2B; needs strategy and team leadership |
| Fractional CRO | $10K to $25K | $250 to $450 | $350K to $600K / yr | $5M to $50M B2B; pipeline, velocity, and forecast accountability |
| Fractional CFO | $8K to $20K | $200 to $400 | $300K to $500K / yr | $5M to $30M; raise, close, or forecasting needs |
| Fractional COO | $10K to $25K | $250 to $450 | $350K to $600K / yr | Scaling fast, or founder buried in operations |
| Fractional CHRO | $8K to $20K | $200 to $400 | $350K to $550K / yr | Crossing 30 to 50 employees, or in major transition |
| Fractional CTO | $10K to $25K | $250 to $450 | $300K to $500K / yr | Pre-Series-B or post-acquisition technical leadership |

Pricing alone does not answer "is this the right hire." Each role has a different mandate, a different sweet spot, and a different shape of value. The cards below summarize the position; each links to the deep dive.
Two companies can pay very different fees for the same fractional role. The five variables, ranked by impact:
A fractional CMO at $15,000 per month is $180,000 per year. A full-time CMO costs $300,000 to $500,000 all-in once you add base, bonus, equity, and benefits. So the fractional model is roughly 25 to 50 percent of full-time cost. Two practical implications:
Fractional is wrong when the function is the company's primary growth engine and demands full-time attention (Series-A SaaS where marketing IS the engine, for example), when you need a full-time presence to manage a large existing team, or when budget is tight enough that a true junior or mid-level full-time hire is a better fit than a senior fractional.
Most fractional engagements are negotiated on three axes: hours, term length, and deliverables tied to KPIs. The discount you get is usually on multi-month commits, not hourly rate.
