# Freelance hourly rate: the formula for pricing your time like a business
TL;DR
- The freelance rate formula is Rate = (Income ÷ (1 − TaxRate) + Expenses) ÷ BillableHours, which grosses a take-home target up for tax, adds overhead, then divides by hours that can actually be invoiced. - Dividing a salary target by hours worked produces a "naive rate" that ignores self-employment tax, business expenses, and non-billable time, three costs an employed worker never prices directly. - Billable utilization is typically 50%–70% of working hours, so a 40-hour week at 65% utilization yields roughly 26 invoiceable hours, not 40. - A modeled scenario of $80,000 take-home, $6,000 expenses, a 28% blended tax rate, four weeks off, and 65% utilization requires approximately $117,111 in gross revenue across 1,248 billable hours, or about $93.84 per hour. - Utilization is the most sensitive variable in the equation: it sits in the denominator, so a ten-point misestimate moves the required rate more than a ten-point tax misestimate does.
An employee negotiating a salary is quoting a number that has already been stripped of employer payroll tax, unreimbursed overhead, and unproductive hours. A freelancer quoting an hourly rate is quoting a number that has to absorb all three. The gap between those two framings is why converting a salary expectation into an hourly rate by simple division produces a figure that is structurally too low, often by a third or more.
The freelance rate equation exists to close that gap. It works backward from a take-home target rather than forward from a market rate, and it forces every cost that an employer would otherwise have carried onto the visible side of the ledger.

Why this metric dictates profitability
A freelance rate is not a wage. It is the unit price of a one-person business, and like any unit price it has to cover cost of delivery, overhead, and the operator's compensation. When the rate is set by dividing a desired salary by hours worked, three costs disappear from the model at once.
The first is tax. Self-employment tax applies at 15.3% on net earnings, covering both the employee and employer halves of Social Security and Medicare, and it stacks on top of ordinary federal and state income tax. Combined effective burdens commonly land in the 25%–35% range depending on filing status, deductions, and jurisdiction. A take-home target therefore has to be grossed up, not merely matched.
The second is overhead. Software subscriptions, liability insurance, equipment replacement, accounting fees, professional development, and health coverage are absorbed by an employer in a salaried arrangement. In a freelance arrangement they are a direct annual cost that must be recovered across billable hours.
The third, and the one most consistently underweighted, is non-billable time. Invoicing, proposal writing, marketing, client acquisition, contract negotiation, and administrative work all consume working hours that produce no invoice line. Because this cost lives in the denominator of the rate equation rather than the numerator, a misestimate compounds rather than adds. Two freelancers with identical income targets and identical expenses will need materially different rates if one bills 55% of their time and the other bills 70%.
Profitability, in this framing, is not a function of how much work is won. It is a function of whether the rate charged on the work that is won was derived from a denominator that reflects reality.
Equation and data inputs
The core relationship grosses the income target up for tax, adds annual overhead, and divides by realistic billable capacity:
\text{Rate} = \frac{\dfrac{\text{TargetIncome}}{1 - \text{TaxRate}} + \text{AnnualExpenses}}{\text{BillableHoursPerYear}}
Billable hours are themselves derived rather than assumed, which is where most of the modeling error enters:
\text{BillableHoursPerYear} = (52 - \text{WeeksOff}) \times \text{HoursPerWeek} \times \text{Utilization}
Substituting the second expression into the first gives the full form:
\text{Rate} = \frac{\dfrac{\text{TargetIncome}}{1 - \text{TaxRate}} + \text{AnnualExpenses}}{(52 - \text{WeeksOff}) \times \text{HoursPerWeek} \times \text{Utilization}}
The naive rate that this formula is designed to replace can be written as follows, and the ratio between the two is the structural undercharge:
\text{NaiveRate} = \frac{\text{TargetIncome}}{52 \times \text{HoursPerWeek}}
Worked scenario. Modeling a target take-home of $80,000, annual business expenses of $6,000, a blended tax rate of 28%, four weeks off, a 40-hour week, and 65% billable utilization:
Gross revenue required = $80{,}000 \div (1 - 0.28) + \$6{,}000 = \$111{,}111 + \$6{,}000 = \$117{,}111$
Billable hours = $(52 - 4) \times 40 \times 0.65 = 1{,}248$
Required rate = $\$117{,}111 \div 1{,}248 \approx \$93.84$
The naive comparison on the same target is $80{,}000 \div (52 \times 40) = \$38.46$ per hour. The modeled rate is roughly 2.4 times the naive figure, which illustrates why salary-to-hourly conversion tends to break down for independent contractors.
Sensitivity check. Holding everything else constant and moving utilization from 65% down to 55% reduces billable hours to 1,056 and raises the required rate to roughly $110.90, an increase of about 18%. Moving the blended tax rate from 28% to 33% instead raises gross revenue required to about $125,403 and the rate to roughly $100.48, an increase of about 7%. The denominator variable is more than twice as sensitive as the tax variable across this range.
Benchmark ranges
The table below summarizes the ranges typically used when modeling the inputs. Actual values vary by discipline, region, client mix, and stage of practice, and the ranges are illustrative rather than prescriptive.
| Input variable | Typical modeled range | Notes on the range |
|---|---|---|
| Blended tax rate (SE + income) | 25%–35% | Includes the 15.3% self-employment component; varies with state tax and deductions |
| Annual business expenses | $2,000–$15,000+ | Higher where equipment, insurance, or health coverage are carried directly |
| Weeks off per year | 2–6 weeks | Unpaid in a freelance arrangement, so it reduces billable capacity directly |
| Billable utilization | 50%–70% | Established practices trend toward the upper end; new practices toward the lower |
| Working hours per week | 30–50 hours | Distinct from billable hours; the input to the utilization multiplier |
| Naive-to-modeled rate ratio | 1.8x–2.6x | The multiple by which simple salary division typically understates the rate |
The model can be run against different income targets, expense loads, and utilization assumptions using the freelance rate calculator, which applies the same equations described above.
