What Profit Margin Does a Consulting Business Have?
A consulting business typically earns a gross margin of 55% to 70% after the cost of delivering engagements, with net profit for a small firm running 15% to 30% after overhead, marketing and admin. Revenue Map's consulting presets model cost of goods at 36% of engagement revenue for a generalist firm, ranging from 30% for fractional executive work to 45% for technical consulting.
Consulting margins are high on paper because the primary input is expertise rather than materials. But the cost of goods in consulting is the loaded cost of the hours delivered: your time if you are solo, or billable staff if you run a firm. Revenue Map's default presets model this at 36% of engagement revenue, which includes the consultant's compensation, any subcontractors and direct delivery expenses. That leaves a 64% gross margin before overhead.
The gap between gross margin and net profit is overhead: office or coworking costs, marketing, insurance, software, admin time and the unbillable hours spent on proposals, business development and internal work. Revenue Map's presets model $6,000 per month of salary-equivalent overhead in phase one, rising to $16,000 at maturity, plus $1,200 of miscellaneous costs. For a solo consultant those costs are lower, but so is the revenue ceiling, which is why net margins often stay in the 15% to 30% range regardless of firm size.

What Moves the Number
Solo versus firm changes margins but not net income
A solo consultant keeps 100% of gross margin but hits a revenue ceiling bounded by billable hours. A firm adds delivery staff whose cost raises COGS from 36% toward 45%, but the higher total revenue can produce more net dollars even at a lower percentage. Revenue Map's presets model the default at 36% COGS, which represents a blend of principal and junior delivery.
Utilization is the hidden margin driver
The presets model organic lead share at 58%, with paid acquisition at $15 per click and just 0.45% click-to-engagement conversion. That low conversion rate means most revenue comes from referrals and reputation, and the real margin question is how many hours per week are billable versus spent on proposals, admin and business development. A utilization rate below 60% compresses net margins even on high gross-margin work.
Engagement type determines the COGS band
Fractional executive work presets at just 30% COGS because one senior person delivers the service with minimal support. Technical consulting runs 45% because delivery requires more junior staff hours. The 15-point spread between these models is the difference between a 70% gross margin and a 55% one, so specialization directly sets your margin profile.
Repeat rate protects margins from acquisition cost
Revenue Map's presets model repeat engagement rates at 12% in phase one growing to 14% at maturity, which is lower than most service businesses. Each new client costs real marketing and proposal time. Firms that raise their repeat rate, fractional executives preset at 55%, spend far less on acquisition per revenue dollar and keep more as net profit.
