Freelance Hourly Rate Calculator: What to Charge to Hit Your Target Income

"How much should I charge per hour?" is probably the worst-answered question in self-employment. The most common answer — dividing the salary you'd like to earn by 1,800 hours, the theoretical number of hours worked in a full-time year — is almost always wrong, and wrong in only one direction: it systematically underestimates the rate actually needed. This calculator reconstructs the correct calculation, line by line, so that none of these items stays implicit or gets forgotten.

Why the "naive" hourly rate is wrong

The salary ÷ 1,800 hours calculation rests on two silent assumptions, both false in practice. The first: that every hour worked is an hour billed to a client. In reality, a significant share of a self-employed person's working time goes to tasks that generate no revenue directly — prospecting, quoting, admin exchanges, industry watch, training. This share varies by field and seniority, but it's never zero, and it's often badly underestimated by people discovering self-employment after a salaried career, where this time exists too but stays invisible because it's already covered by the salary.

The second false assumption: that billed revenue equals net income. Between the two sit social charges and taxes, which can represent, depending on legal status and country, between a quarter and half of billed revenue — plus business expenses, which are added before any tax is even calculated. A calculation that ignores these two layers mechanically produces a displayed rate roughly half of what's actually needed to reach the target income.

The real billable rate

The key concept for fixing this calculation is the billable ratio (or billable utilization rate): the proportion of total working time that translates into hours actually billed to a client. Surveys conducted regularly among independent consultants across several fields put this ratio, on average, somewhere between 55% and 75% for an established practice — rarely above, never durably at 100%. When starting out, while the client base is still being built, this ratio is often noticeably lower: prospecting takes up disproportionate space relative to billed time.

This ratio isn't a fate to suffer but a parameter to measure: keeping even a rough tally of time actually billed over a month or quarter gives a far more reliable estimate than a gut feeling. It's also a lever for action: improving your billable ratio (by delegating admin work, professionalizing prospecting, building a base of recurring clients) often has a faster, more direct effect on net income than raising the hourly rate itself, which sooner or later runs into what the market will actually pay.

Non-billable time, item by item

Non-billable time isn't limited to prospecting. It includes administrative and accounting management, industry watch and ongoing training (essential in most fields to stay competitive), exchanges with prospects who ultimately don't sign, writing proposals, and — often forgotten — unpaid periods of unavailability: illness, personal emergencies, gaps between assignments. An absent employee keeps getting paid; an absent freelancer bills nothing that day, which is why these periods should be anticipated in the rate calculation rather than discovered after the fact in the bank account.

The business expenses people forget

Beyond the obvious monthly expenses (software, insurance, a professional internet subscription), some cost items are irregular and therefore easily forgotten in a quick calculation: replacing computer equipment every three to five years, occasional but costly training, year-end accounting fees, a possible professional association due or a sector-specific insurance policy. Good practice is to smooth these irregular expenses over the year to get a realistic annual figure, rather than counting only what's paid monthly by direct debit — which is exactly what this calculator does with the "annual business expenses" field.

Worked example

Let's take a target net income of 45,000 per year (in the currency unit of your choice), 220 working days in the year at 8 hours per day, a billable ratio of 65%, 6,000 in annual business expenses, and a combined tax and charges rate of 28%.

Billable hours for the year come to 220 × 8 × 65% = 1,144 hours — far fewer than the 1,760 theoretical hours (220 × 8) that a calculation ignoring non-billable time would suggest. The base need (target net income + business expenses) is 51,000. A 10% safety margin adds 5,100, bringing the total need to 56,100. Once this amount is "grossed up" to absorb the 28% charges rate, the revenue that needs to be billed for the year reaches roughly 77,917.

Spread across the 1,144 billable hours, that gives an hourly rate of roughly 68, or a daily rate of roughly 545 for a fully billed day. On the breakdown of that revenue: net income accounts for a little over half of the total billed, taxes and charges absorb a little over a quarter, and business expenses plus the safety margin share the rest. This last point often comes as a surprise: over 40% of billed revenue goes somewhere other than the freelancer's pocket — a proportion a "salary ÷ hours" calculation never reveals.

How to announce a rate increase

Once the rate has been correctly recalculated, announcing it to existing clients calls for a different approach than simply communicating a new number. Justifying the increase with the actual evolution of your costs and added value (new skills, better efficiency, demonstrated results) rather than a vague formula ("cost of living is rising") strengthens its legitimacy. Giving enough advance notice — one to three months depending on the nature of the relationship — gives the client time to plan for it in their own budget rather than discovering it on an invoice. Applying the increase to new engagements rather than mid-engagement avoids a sense of changing the rules partway through. Finally, a gradual, regular increase (annual, for instance, aligned with a planned rate review) is almost always better received than a rare but brutal increase made necessary by years without adjustment.

What the salaried comparison reveals

The rate calculated here, once compared to the equivalent salary for the same net income, almost always far exceeds the value of a salaried workday — and that's expected, not an anomaly in the calculation. An employee gets paid on paid leave days and public holidays without working; their employer contributions and social coverage are funded by the employer on top of their gross salary; their equipment, software, and training are most often covered by the company. A freelance daily rate has to fund, on top of the targeted net income, everything that salaried employment makes invisible because someone else covers it behind the scenes. Understanding this gap, rather than seeing it as just a high number to justify to clients, helps set a rate that doesn't collapse the first time you take an unbilled week off.

Frequently asked questions

Why can't my hourly rate just be "target salary ÷ 1,800 hours"?

Because that calculation assumes 100% of your working hours are billed to a client, which never happens in practice: prospecting, quoting, admin work, training, and unpaid sick days all eat into a real share of your time. It also assumes billed revenue equals net income, ignoring taxes, social charges, and business expenses. A "naive" calculation of this kind systematically underestimates the rate actually needed — sometimes by 50% or more.

What exactly is the "billable ratio"?

It's the share of your working time actually billed to a client, expressed as a percentage of total time worked. A 65% ratio means that out of 8 hours worked on a given day, roughly 5.2 hours are billable and 2.8 hours go to non-billable tasks (prospecting, admin, training). This ratio varies enormously by field and experience level: often lower when starting out (prospecting takes up disproportionate space), it tends to improve with an established client base, without ever durably reaching 100%.

Which business expenses should I include?

Everything your activity costs you regardless of hours worked: computer equipment and its depreciation, software subscriptions, professional liability insurance, office or coworking space, non-billed travel, accounting fees, ongoing training, professional association dues. The most common mistake is forgetting irregular items (replacing equipment every 3-4 years, occasional training) and counting only the obvious recurring monthly expenses.

How does this calculator determine the tax and social charges rate?

It doesn't — you enter it yourself. Legal structure, country, and income level make this rate vary enormously, and no tax rule is hard-coded into this tool. The charges rate is treated as a flat percentage applied to billed revenue — it's up to you to enter a realistic estimate for your situation (your accountant or the relevant tax authority are reliable sources for this figure).

What is the 10% "safety margin"?

A flat buffer added to the base need (target net income + business expenses) before calculating the rate, meant to absorb the unexpected that no other parameter explicitly captures: an unpaid invoice, an unusually slow month, equipment that needs urgent replacement. It's neither a tax nor a charge — it's structural prudence, consistent with the fact that self-employment offers none of the automatic protections of salaried work.

How should I read the comparison with a salaried position?

It converts your target net income into an equivalent gross salary, then spreads that gross salary across all of a salaried employee's "paid" days — days worked AND paid leave days, since an employee gets paid even on days they don't work. The resulting figure (the "value of a salaried workday") is then compared to your freelance daily rate: the gap, almost always strongly positive, illustrates why self-employment must structurally charge more per day worked than an equivalent salaried position, paid leave and employer contributions included in the calculation.

Can the calculator tell me the reverse: how much I'll net at a given rate?

Yes — it's the mirror function of the main calculation: starting from an hourly rate, billable time, expenses, and the charges rate, it reconstructs the corresponding annual net income. Useful for quickly checking whether a rate imposed by a client (or common among competitors) is compatible with your target income, without redoing the calculation by hand in the other direction.

Are the 3 preset profiles (beginner / experienced / expert) reliable for my field?

They're illustrative starting points, not market data: they mainly show how the billable ratio and target income typically evolve with experience (more billable time, higher target income), not reference rates for any given profession. Replace them with your own figures as soon as you have a realistic estimate — the calculator stays correct regardless of field, only the input parameters need to reflect your actual situation.
