This consulting fees calculator works backwards from the income you want to take home. Give it your annual target, your effective tax rate, and the hours you can actually bill. It returns the hourly rate you need to charge, plus the matching day rate, weekly rate, and monthly retainer. Business expenses and a profit buffer are factored in, so the number you see is one that keeps the practice running and pays you properly.
This calculator flips the sequence. You start with the take-home pay you want, set your tax burden, and enter the realistic number of hours you can invoice in a year. Expenses and a reinvestment buffer get added on top, and the total is divided by billable time. The result is the rate your situation actually requires.
Four pricing units come out of it: hourly, daily, weekly, and monthly retainer. A utilization scenario table shows how the required rate shifts at 50%, 70%, or 90% billable time. That’s the table most solo consultants come back to when they’re deciding whether a lower-rate project is worth the calendar space.
Choose your currency from the dropdown.
Enter the annual take-home pay you want in your pocket.
Set your effective tax rate, covering income, self-employment, and local taxes.
Enter your billable hours per week and the number of weeks you plan to work.
Set your billable utilization rate, or the share of working hours you actually invoice.
Add your annual business expenses.
Set a profit and reinvestment buffer.
Read the recommended hourly rate, plus the day, week, and monthly retainer figures.
The core formula starts from the money you need and works backwards to the price you have to charge.
Formula: Hourly Rate = Total Revenue Required ÷ Billable Hours per Year
Where:
Total Revenue Required = (Pre-tax Income + Annual Expenses) ÷ (1 − Buffer %)
Pre-tax Income = Take-home Pay ÷ (1 − Tax Rate)
Billable Hours per Year = Hours per Week × Weeks Worked × Utilization %
Once the hourly rate is set, the other units follow: Day Rate = Hourly × Hours in a Billable Day. Weekly Rate = Hourly × Hours per Week. Monthly Retainer = Total Revenue Required ÷ 12.
Two things to note. The buffer is applied to revenue, not to income, so it scales with the size of the practice. And the utilization rate reduces your gross working hours to billable hours, which is where most consultants underprice themselves. If you work 40 hours a week but only bill 28, your true cost per billable hour is 43% higher than it looks.
Suppose you want to take home $175,000 this year. Your effective tax rate is 32%. You can bill 28 hours a week for 47 weeks, with utilization at 72%. Annual business expenses run $24,000, and you want an 18% buffer for slow months and reinvestment.
Step 1: Pre-tax income. $175,000 ÷ (1 − 0.32) = $257,352.94.
Step 2: Revenue base. $257,352.94 + $24,000 = $281,352.94.
Step 3: Revenue required. $281,352.94 ÷ (1 − 0.18) = $343,113.34.
Step 4: Billable hours. 28 × 47 × 0.72 = 947.52 hours.
Step 5: Hourly rate. $343,113.34 ÷ 947.52 = $362.12 per hour.
From there: day rate is $2,896.96, weekly rate is $10,139.36, and monthly retainer is $28,592.78. The calculator places this in the “Strong” band ($250 to $400 per hour), which fits senior or highly specialized consulting. The fully loaded cost per billable hour works out to $297.74, so anything below that rate actually loses money.
Divide your required annual revenue by your billable hours per year. Required revenue is your take-home pay grossed up for tax, plus business expenses, divided by one minus your buffer percentage. Billable hours are your weekly hours times weeks worked times utilization rate.
Experienced independents usually charge $100 to $250 per hour. Specialists in strategy, tech, and finance often reach $250 to $400. Junior consultants and generalists typically land between $50 and $100. The right number for you depends on your niche, market, and cost base.
Most independent consultants bill between 1,000 and 1,400 hours per year. That assumes 30 to 35 billable hours a week across 45 to 48 weeks. Anything above 1,500 billable hours is aggressive and often burns people out within a year or two.
It’s the share of your working hours that you actually invoice. Independent consultants usually run 60% to 80%. If you work 40 hours a week and bill 28 of them, that’s 70% utilization. The remaining time goes to admin, sales, and skill development.
Charge by the day for workshops, audits, and on-site work where the scope isn’t easily divided into hours. Charge by the hour for ongoing retainers and small, well-defined tasks. Day rates cap client exposure and remove the temptation to round billable hours down.
Start with the annual revenue required, divide by 12, and check that the monthly figure matches the hours you’re committing. If the retainer includes 40 hours of work per month, your effective hourly rate should be at or above your standard rate. If it’s below, renegotiate the scope or raise the fee.
A high calculated rate usually means your income target is ambitious relative to your billable hours, or your utilization is set low. It could also mean your expenses are heavy. Check each input. If the numbers are right, the market may simply not support the rate, and you’d need to change the target, raise utilization, or cut costs.
Use your effective tax rate, which is the total tax you pay divided by your gross income. For US independent consultants, that usually falls between 25% and 40% once self-employment tax and state tax are included. Freelancers in other countries should use their local combined rate.
Yes. The math is the same for freelancers, contractors, and solo consultants. The labels say “consulting” but the inputs cover any independent service business that bills for time. Just adjust the utilization and expenses to match your situation.
The profit and reinvestment buffer is designed for this. A buffer of 15% to 25% builds in room for months with low revenue, plus savings for equipment, software, and taxes. The buffer is applied to revenue, so it scales with the size of your practice.
Change the take-home input and the calculator updates everything below it. If your target moves up by $20,000, your required hourly rate will move up proportionally, unless you also raise hours or utilization to compensate. Run the numbers before you quote new clients.
No. It assumes the revenue you bill is the revenue you collect. If you regularly deal with late payers or write-offs, add a small percentage to your buffer or expenses to reflect that risk. A few points of buffer usually covers it.
