Businesses hire consultants for expertise they don’t have in-house: strategy, marketing, operations, technology, compliance and more. BLS doesn’t track "consultants" as one occupation, but related roles show the landscape: market research analysts and marketing specialists held about 941,700 jobs in 2024, with a median wage of $76,950 and 7% projected growth, and business operations specialists earned a median of $80,410 in May 2024.
Consulting is easy to start and hard to scale. Independent consultants keep most of what they earn; firms grow by hiring consultants and winning larger engagements.

Business models compared
The figures below are illustrative months from our step-by-step guides, not industry averages. They show how revenue and costs typically fit together; your market, prices and costs will differ.
| Business model | Startup costs | Example monthly revenue | Costs | Profit before owner pay | Margin |
|---|---|---|---|---|---|
| Independent consultant | Low: expertise, website, insurance | $15,000 | $1,800 | $13,200 | 88% |
| Small consulting firm (3 consultants) | Moderate: consultants, sales, office | $50,000 | $36,800 | $13,200 | 26% |
| Niche consultant for one industry (e.g. contractors) | Low: industry expertise, case studies | $20,000 | $7,150 | $12,850 | 64% |
Fixed and variable costs
For projections, the most useful split is between variable costs, which rise and fall with sales (materials, parts, hourly labor), and fixed costs, which you pay every month regardless (rent, salaried staff, insurance, loan payments).
| Business model | Variable costs (% of revenue) | Fixed costs per month | What it means |
|---|---|---|---|
| Independent consultant | 3.3% | $1,300 | Low costs overall: time is the main constraint |
| Small consulting firm (3 consultants) | 5.0% | $34,300 | Mostly fixed: slow start-up months are expensive |
| Niche consultant for one industry (e.g. contractors) | 4.0% | $6,350 | Low costs overall: time is the main constraint |
What the numbers say
Independent consultants have very low overhead, so margins are high.
Firms add salaries before engagements grow, creating long ramps.
Niche consultants win referrals faster by specializing in one industry.
The three models in brief
Independent consultant. One expert working with a few clients at a time.
Small consulting firm. Several consultants handling larger projects.
Niche industry consultant. Specialized expertise, for example helping contractors with operations or marketing.
Cost structure: small consulting firm (3 consultants)

A first-year projection: small consulting firm (3 consultants)
New businesses rarely start at full speed. This projection assumes revenue ramps from 35% of the example month in month 1 to 100% by month 12, variable costs move with revenue, and fixed costs stay the same every month. It’s a planning illustration, not a forecast.
| Month | Revenue | Variable costs | Fixed costs | Profit | Cumulative |
|---|---|---|---|---|---|
| 1 | $17,500 | $875 | $34,300 | -$17,675 | -$17,675 |
| 2 | $22,500 | $1,125 | $34,300 | -$12,925 | -$30,600 |
| 3 | $27,500 | $1,375 | $34,300 | -$8,175 | -$38,775 |
| 4 | $31,000 | $1,550 | $34,300 | -$4,850 | -$43,625 |
| 5 | $35,000 | $1,750 | $34,300 | -$1,050 | -$44,675 |
| 6 | $38,000 | $1,900 | $34,300 | $1,800 | -$42,875 |
| 7 | $41,000 | $2,050 | $34,300 | $4,650 | -$38,225 |
| 8 | $43,500 | $2,175 | $34,300 | $7,025 | -$31,200 |
| 9 | $45,500 | $2,275 | $34,300 | $8,925 | -$22,275 |
| 10 | $47,500 | $2,375 | $34,300 | $10,825 | -$11,450 |
| 11 | $49,000 | $2,450 | $34,300 | $12,250 | $800 |
| 12 | $50,000 | $2,500 | $34,300 | $13,200 | $14,000 |
Year one: revenue $448,000, profit before owner pay $14,000. The first profitable month is month 6. Cumulative results bottom out at -$44,675, which is the minimum cash cushion this plan would need, before any startup costs.
Consultant salaries come before engagements fill, so this firm illustration turns profitable in month 6, with a cumulative low of about $44,700. Many firms start with the founder’s own client base.

About this data
Workforce figures come from the U.S. Bureau of Labor Statistics (Occupational Outlook Handbook and Occupational Employment and Wage Statistics, May 2024 and the 2024 to 2034 projections). Market figures cite their sources in the list above. Business model figures are illustrative months built from typical prices and costs to show how revenue, fixed costs and variable costs fit together; they are not industry averages or guarantees. We review these profiles when new government data is released, at least once a year. The same figures are available in a structured format for Advanton’s upcoming business projection tool.
