How Much to Charge as a Freelancer: A Real Formula

Adam A.July 24, 20267 min read

Figuring out how much to charge as a freelancer comes down to one honest equation: the rate that covers your income goal, your business expenses, and your taxes — divided by the hours you can actually bill, not the hours you work. There is no single correct number, and any "average freelance hourly rate" you find online blends wildly different skills, regions, and experience levels into a figure that describes no one in particular. The rate that works for you is the one your own costs and your own billable hours can defend.

So skip the market-average shortcut. A rate you can stand behind is built from the bottom up, and most of the work is being honest about two things people routinely get wrong: what your taxes actually take, and how few of your working hours are billable.

A formula for how much to charge as a freelancer

The most defensible way to set a freelance rate is a single division:

Hourly rate = (target income + business expenses + tax) ÷ actual annual billable hours

Three things make this formula better than guessing a number or copying a competitor:

The numerator is everything you need to bring in — not just your take-home pay, but the software, hardware, insurance, and tax that come out before you ever see it.
The denominator is billable hours, not worked hours — the hours a client actually pays for, which is always fewer than the hours you sit at your desk.
It is yours — plug in your numbers and you get a floor that's true for your costs, your tax situation, and your real capacity.

Get either side wrong and the rate is fiction. The two most common mistakes are forgetting how much tax self-employment carries, and dividing by 2,080 as if every hour were billable.

Build up from your real costs first

Before you can price an hour, you have to know what a year actually costs you. Two buckets matter most.

Business expenses. Software subscriptions, hardware, a co-working desk, professional insurance, accounting fees, your own pension contributions. These are easy to underestimate because they trickle out monthly. Add them up annually and fold them into the numerator.

Tax. This is the one freelancers most often shortchange. In the US, the self-employment tax rate is 15.3% — 12.4% for Social Security plus 2.9% for Medicare (per the IRS) — and that sits on top of ordinary income tax. A few details worth knowing:

Self-employment tax detail	What it means
Rate	15.3% = 12.4% Social Security + 2.9% Medicare
Social Security cap	Applies only up to an annual wage base — $184,500 for 2026 (up from $176,100 in 2025)
Medicare cap	None — the 2.9% applies to all self-employment income
Taxable base	Figured on 92.35% of net self-employment earnings via Schedule SE
Deduction	You can deduct the employer-equivalent half of SE tax when calculating adjusted gross income

The numbers and brackets shift, and rules outside the US differ entirely, so confirm current figures with the relevant tax authority or an accountant. The point that doesn't change: a freelancer charging like an employee, ignoring the self-employment tax an employer would normally split, is quietly underpricing every hour.

You can't bill every hour you work

Here is the assumption that wrecks freelance rates. A standard full-time year is about 2,080 hours (52 weeks × 40 hours), so dividing your income goal by 2,080 silently assumes every hour is billable. None of them are.

Every billable hour has to be earned twice — once by doing the work, and once by finding, scoping, scheduling, and invoicing it. That second job is unpaid and never goes away. A Freelancer Map survey (reported by Clockify) found that nearly half of freelancers spend roughly six hours a week on non-billable administration and accounting alone — and that figure excludes marketing, proposals, and learning, so total non-billable time runs higher.

Even well-run agencies, where someone else does the selling, don't bill the whole week. According to SPI Research's 2026 Professional Services Maturity Benchmark, industry billable utilization fell to an all-time low of 66.4% in 2025, below the prior record low of 68.9% in 2024 (2025 benchmark, PDF); SPI treats 70% as the minimum healthy benchmark and notes high-performing firms sustain around 75%. Those numbers describe professional-services firms, not solo freelancers — but they prove the broader rule: nobody bills 100% of their available hours. (For the freelancer-specific picture, see how many billable hours per week is realistic and how to read your billable utilization rate.)

What that does to the math:

Billable share of a 40-hour week	Billable hours/week	Roughly per year
50%	20	~1,040
60%	24	~1,250
70%	28	~1,450
80%	32	~1,660

Annual totals here are planning assumptions, not measured statistics — they show direction, not a guarantee. But the lesson is stark: at 60–70% billable, you have 24–28 billable hours a week, not 40. Because a meaningful slice of every week is non-billable, the true rate you need to hit an income target is materially higher than income-goal-÷-2,080 would suggest — often by a third or more. If you're unsure which of your hours count, billable vs non-billable hours draws the line, and how to calculate billable hours shows the method.

A worked illustration

Numbers make it concrete. Treat the figures below as an illustration, not a recommendation — the result depends entirely on the inputs you choose:

Input	Example value
Target take-home income	$70,000
Business expenses	$8,000
Estimated tax (illustrative)	$22,000
Total to earn	$100,000
Actual annual billable hours (28/week × ~45 weeks)	~1,260
Implied hourly rate	~$79

Now watch what happens if you'd used 2,080 hours instead of 1,260: the same $100,000 implies a rate near $48 — a number that looks competitive and quietly guarantees you miss your goal by a wide margin. The gap between those two figures is the entire reason careful freelancers charge what they do. Run the formula with your own income target, expenses, tax estimate, and an honest billable-hours figure, and you get a floor — the rate below which the year doesn't add up.

Set the floor, then price for value

The formula gives you a floor, not a ceiling. It tells you the least you can charge and still hit your goal; it says nothing about what the work is worth to the client.

Above that floor, value is the better guide. A project that saves a client weeks of internal time, or directly drives revenue, can justify a rate far above your cost-based minimum — and pricing the outcome rather than the hour is often where experienced freelancers and consultants make their margin. But the floor still matters: it's the line that tells you when a "good" project is actually losing you money once tax and non-billable time are counted. Know the floor first, then negotiate up from a position of fact.

Track your real billable hours instead of guessing

Every part of this formula is only as good as one input you probably can't recall accurately: your actual billable hours. Most freelancers overestimate it, because the hours they forget to log make them look more utilized than they are, while the non-billable time they never record hides where the week went. Both errors push in the flattering direction — which is exactly why a gut estimate sets your rate too low.

The fix is to measure one honest month, billable and non-billable alike, and let the real ratio set your denominator. That's the job passive tracking does. BillNotch records your active window automatically on Windows, macOS, and Linux — no timer to start — and uses keyword rules and optional AI to sort the day into client projects, with billable status inherited per project. After a month you can see your true billable share instead of guessing it, turn the live billable total into a PDF invoice or CSV, and let its Revenue Leak Finder flag billable time you tracked but never invoiced — the hours that silently lower your effective rate.

A rate built on measured hours is one you can hold in a negotiation without flinching. Start with the formula, then let the data confirm the denominator.
