The question of your daily rate comes up at every stage of a freelancer's career. When starting out, you set it by looking at what others charge. After a few months, you adjust based on what clients are willing to pay. After a few years, you take it for granted and stop questioning it altogether.
The problem is that at none of these stages is the daily rate grounded in measured reality. It's based on the market, on gut feeling, on negotiation -- never on the time actually spent or the real costs of running the business. Yet a daily rate disconnected from reality can create the illusion of profitability for years, while the freelancer is slowly losing money.
This article offers a comprehensive method for setting a fair daily rate, grounded in real time data, verified costs, and an explicit margin. With concrete calculations, not approximations.
The problem: a daily rate based on the market, not your real costs
Most freelancers set their daily rate by combining two sources of information: market rates (platforms, forums, peer exchanges) and their own gut feeling ("will the client accept this price?").
This is an understandable approach, but it has a major flaw: it doesn't account for the individual freelancer's cost structure. Two freelancers with the same daily rate can have radically different profitability levels.
Let's take a simple example.
Marie and Thomas are both freelance React developers. They both charge EUR 550/day. But:
- Marie operates as a sole proprietor, works from home, has no expensive software subscriptions, and manages to bill 18 days per month on average.
- Thomas runs a limited company, rents a coworking space (EUR 350/month), uses several paid tools (IDE, CI/CD, monitoring), and only bills 14 days per month because he spends more time on prospecting and administrative tasks.
At the same daily rate of EUR 550, Marie generates a comfortable net income. Thomas, after social charges, corporate tax, rent, and tools, ends up with an income comparable to a salaried position -- without the job security, paid leave, or company health insurance.
The "market" daily rate says nothing about your personal profitability. Only an approach based on your actual costs and your truly available time can give you a fair daily rate.
Common mistake: Setting your daily rate by taking the gross salary of an equivalent salaried position and dividing it by 20 working days. This method ignores employer contributions (which the freelancer pays themselves), holidays (which the freelancer doesn't get paid for), non-billable time, and the absence of a safety net (unemployment insurance, severance). A daily rate calculated this way underestimates the necessary rate by 30 to 50%.
The complete formula for a profitable daily rate
Here is the formula we recommend. It takes into account all real parameters, not just the target income.
Step 1: Define your annual net income target.
This is the starting point. How much do you want to earn, net, after taxes and charges? This amount should cover your lifestyle, savings, and a buffer for lean months. Let's set a target of EUR 50,000 net per year.
Step 2: Work backwards to charges and costs.
Depending on your legal status, social charges and taxes vary considerably. Here are the rough figures:
| Item | Sole proprietor (BNC) | EURL (corporate tax) | SASU (corporate tax) |
|---|---|---|---|
| Net income target | EUR 50,000 | EUR 50,000 | EUR 50,000 |
| Social charges | ~EUR 11,000 (22%) | ~EUR 22,500 (45% of salary) | ~EUR 35,000 (70% of salary) |
| Income tax | ~EUR 5,500 | ~EUR 5,500 | included in gross |
| Annual fixed costs (accounting, tools, insurance, coworking) | ~EUR 2,000 | ~EUR 5,000 | ~EUR 6,000 |
| Buffer for gaps between contracts (10%) | ~EUR 5,000 | ~EUR 5,000 | ~EUR 5,000 |
| Revenue needed | ~EUR 73,500 | ~EUR 88,000 | ~EUR 96,000 |
These figures are simplified to illustrate the mechanism. In practice, have the exact amounts validated by your accountant. But the order of magnitude is clear: to earn EUR 50,000 net, you need to generate between EUR 73,000 and EUR 96,000 in revenue depending on your legal structure.
Step 3: Calculate the number of actually billable days.
This is where most freelancers get it wrong. They start from 220 working days (52 weeks x 5 days - public holidays) and assume they'll bill 200 days or more.
In reality, the number of billable days must account for:
- Holidays: 5 weeks minimum, or 25 days.
- Public holidays: about 8 days.
- Sick days and unexpected events: 5 to 10 days.
- Non-billable time: prospecting, admin, training. If your billable time ratio is 70%, you lose 30% of your working time to non-billed activities.
The realistic calculation:
| Parameter | Days |
|---|---|
| Working days in the year | 228 |
| Holidays (5 weeks) | -25 |
| Public holidays | -8 |
| Sick days and unexpected events | -7 |
| Days worked | 188 |
| Billable rate (70%) | x 0.70 |
| Days actually billed | 132 |
188 days worked, of which only 132 are billed. Not 200. Not 180. 132.
Step 4: Calculate the daily rate.
The formula is now simple:
Daily rate = Revenue needed / Billed days
| Legal status | Revenue needed | Billed days | Calculated daily rate |
|---|---|---|---|
| Sole proprietor | EUR 73,500 | 132 | EUR 557 |
| EURL (corporate tax) | EUR 88,000 | 132 | EUR 667 |
| SASU (corporate tax) | EUR 96,000 | 132 | EUR 727 |
For a target of EUR 50,000 net, the required daily rate ranges from EUR 557 (sole proprietor) to EUR 727 (SASU). A freelancer running a SASU who charges EUR 500/day doesn't earn EUR 50,000 net. They earn roughly EUR 34,000 -- equivalent to the salary of a junior manager, without job security.
Adjusting your daily rate with real time data
The formula above relies on a key assumption: the billable time ratio. We used 70%, but this figure varies considerably from one freelancer to another. And this is precisely where time tracking data becomes indispensable.
The impact of the billable ratio on the daily rate.
Let's revisit the example of a sole proprietor freelancer aiming for EUR 50,000 net (revenue needed: EUR 73,500), with 188 days worked:
| Billable ratio | Billed days | Required daily rate |
|---|---|---|
| 80% | 150 | EUR 490 |
| 75% | 141 | EUR 521 |
| 70% | 132 | EUR 557 |
| 65% | 122 | EUR 602 |
| 60% | 113 | EUR 650 |
| 55% | 103 | EUR 713 |
The difference between an 80% and a 60% ratio amounts to EUR 160 per day. Over a year, that's the difference between a competitive daily rate and one that many clients will refuse.
This is why measuring your actual time is an economic act, not a bureaucratic exercise. A freelancer who discovers, data in hand, that their billable ratio is 60% instead of the 75% they assumed, must either raise their daily rate by 25% or restructure their time to recover 15 percentage points of billable work.
How to improve your billable ratio.
Time tracking data doesn't just help you calculate -- it enables you to take action. Here are the most common levers:
- Batch administrative tasks into a fixed slot (Friday morning, for example) instead of scattering them throughout the week. The administrative time doesn't decrease, but the interruptions caused by fragmentation do.
- Streamline prospecting. A standard quote template, a proposal template, pre-written responses to common questions -- every minute saved in pre-sales is a minute recovered for production.
- Select your clients. A client who demands many meetings, reports, and revisions generates a lower billable ratio than an autonomous client who validates quickly. Time data lets you measure this difference objectively.
- Limit context switching. Organizing your week into blocks dedicated to a single client reduces the time lost to transitions. We explore this topic further in our article on organizing time across multiple clients.
Case studies: 3 profiles, 3 different daily rates
To make the method concrete, let's apply it to three real freelancer profiles.
Profile 1: Sophie, junior web developer (2 years of experience)
- Legal status: sole proprietor.
- Net income target: EUR 35,000.
- Charges and costs: 22% social charges, EUR 1,500/year in fixed costs, 10% buffer.
- Revenue needed: approximately EUR 51,000.
- Days worked: 188.
- Measured billable ratio: 72% (she spends little time on prospecting; her clients come through referrals).
- Billed days: 135.
- Calculated daily rate: 51,000 / 135 = EUR 378/day.
Sophie was charging EUR 350/day based on "what other juniors around me charge." Her data shows she should charge at least EUR 378 to reach her goal. The EUR 28/day gap represents EUR 3,780 per year.
Profile 2: Antoine, senior UX/UI designer (7 years of experience)
- Legal status: EURL (corporate tax).
- Net income target: EUR 60,000.
- Charges and costs: 45% social charges, accountant, Adobe/Figma tools, coworking space.
- Revenue needed: approximately EUR 112,000.
- Days worked: 188.
- Measured billable ratio: 62% (heavy pre-sales time due to RFP-based work, and time-consuming back-and-forth validation with clients).
- Billed days: 117.
- Calculated daily rate: 112,000 / 117 = EUR 957/day.
Antoine was charging EUR 700/day. With a 62% billable ratio, this rate only allows him to net EUR 44,000 -- well below his target. Two options: raise his daily rate to EUR 950 (which his experience and specialization justify), or improve his billable ratio by reducing pre-sales time (better prospect qualification, declining low-probability RFPs).
Profile 3: Laura, digital strategy consultant (10 years of experience)
- Legal status: SASU.
- Net income target: EUR 75,000.
- Charges and costs: high social charges (SASU), frequent travel, premium subscriptions (market research, analytics tools).
- Revenue needed: approximately EUR 152,000.
- Days worked: 188.
- Measured billable ratio: 68% (travel time, presentation preparation, networking).
- Billed days: 128.
- Calculated daily rate: 152,000 / 128 = EUR 1,188/day.
Laura was charging EUR 950/day. Her data reveals a shortfall of EUR 238 per billed day, or more than EUR 30,000 per year. The fix involves gradually increasing the daily rate for new clients, combined with better mission selection to improve the billable ratio.
Key takeaway: The daily rate is not a market price. It's a cost price plus a margin. If you don't know your real cost price -- because you don't measure your time -- you're setting your price in the dark. Time data is the foundation of a fair daily rate and a reliable future quote.
In summary, the method comes down to four steps: define a net income target, calculate the revenue needed by factoring in all charges, measure the number of actually billable days through time tracking, and divide. The result is rarely what you expected -- and that's precisely why running the calculation is essential.
