How to Set Consulting Fees

Why consultants use a cost build-up

Employees receive salary plus benefits an employer funds. Consultants must cover that same lifestyle target, buy their own benefits, pay business overhead, fund unpaid sales time, and still earn profit. Dividing last year’s W-2 by 2,000 hours rarely survives contact with reality because it skips those layers.

A cost build-up translates “I used to make about $X” into a daily rate you can quote, then an hourly rate for T&M work. The Consulting Fee Calculator automates that stack and shows how your detailed rate compares to the familiar 3× rule heuristic.

The build-up formula (and what utilization does)

The calculator walks these steps:

1. Daily salary = annual salary ÷ working days per year
2. Loaded daily = daily salary + (daily salary × benefits %) + (annual overhead ÷ working days)
3. Consulting daily = loaded daily × profit multiplier
4. Hourly rate = consulting daily ÷ hours per day

Utilization enters only on the revenue side:

• Annual revenue = consulting daily × (working days × utilization %)
• Monthly revenue = annual revenue ÷ 12

Lower utilization reduces projected annual and monthly revenue because fewer days are billable at your consulting daily rate. It does not raise or lower the hourly rate shown in the hero output. Hourly comes strictly from consulting daily divided by hours per day. If you need a higher hourly to hit an income goal with low utilization, adjust salary targets, overhead, profit multiplier, or hours per day, not utilization as a hidden rate dial.

The tool also computes the 3× rule: (salary ÷ 2,000) × 3. That rule assumes roughly 2,000 billable hours and triples the implied employee hourly. Your build-up may land above or below it depending on benefits, overhead, and multiplier.

What each input should represent

• Salary: the W-2-equivalent lifestyle number you want the practice to replace, not a stretch goal unless you are stress-testing.
• Benefits %: health, retirement match, payroll taxes employers paid. Many solo consultants plan 25% to 40% depending on coverage.
• Overhead: annual fixed business costs (software, insurance, accounting, coworking) spread across working days.
• Profit multiplier: values at or above 1.0 add margin above loaded cost. 1.4 means consulting daily is 140% of loaded daily.
• Hours per day: billable hours you pack into a sold day, often 6 to 8, not every hour at the desk.
• Working days: billable calendar days before vacations and gaps. Mid-200s is common in the US.
• Utilization %: share of working days you expect to invoice. Use it to sanity-check annual revenue, not to derive hourly.

How to use the calculator

1. Open the Consulting Fee Calculator.
2. Enter salary, benefits %, and annual overhead.
3. Set profit multiplier, hours per day, and working days.
4. Read hourly rate, daily rate, and 3× rule comparison.
5. Adjust utilization to see annual and monthly revenue at your consulting daily rate.
6. Cross-check capacity with the Capacity Planner and billable time with the Billable Hours Calculator.

Worked example (matches the tool)

Inputs: $120,000 salary, 35% benefits, $24,000 overhead, 1.4× profit multiplier, 8 hours per day, 230 working days, 70% utilization.

1. Daily salary: $120,000 ÷ 230 ≈ $521.74
2. Loaded daily: $521.74 + 35% benefits + ($24,000 ÷ 230 overhead) ≈ $808.69
3. Consulting daily: $808.69 × 1.4 ≈ $1,132.17
4. Hourly rate: $1,132.17 ÷ 8 ≈ $141.52
5. 3× rule check: ($120,000 ÷ 2,000) × 3 = $180/hr heuristic
6. Annual revenue at 70% util: $1,132.17 × (230 × 0.70) ≈ $182,280
7. Monthly revenue: ≈ $15,190

Drop utilization to 50% without changing other inputs and annual revenue falls to about $130,200 while hourly stays $141.52. That is the distinction: utilization forecasts how much you bill at your day rate, not what hourly you must charge.

After you have a rate: packages and positioning

Many consultants publish day rates or fixed scopes while keeping an internal hourly floor. Convert with the Day Rate Calculator, model fixed bids in Project Pricing, and test value framing in Value-Based Pricing when outcomes are measurable. If scope expands on a fixed fee, the Scope Creep Calculator shows effective hourly erosion.

Common mistakes

• Using utilization to “fix” hourly: utilization changes revenue projections only in this tool.
• Skipping overhead: insurance and tools are real cost even when revenue is lumpy.
• Treating 3× rule as law: it is a benchmark, not a contract minimum.
• Planning 100% utilization: sales, admin, and vacation days exist.
• Ignoring payment terms: a strong day rate on Net 60 still strains cash. See Net 30 cash flow.
• Never revisiting the build-up: premiums, overhead, and calendar change yearly.
