Utilization rate for freelancers, explained

Utilization rate is the share of your working hours you actually bill to clients, calculated as billable hours divided by total working hours. For a solo freelancer, healthy is roughly 50 to 70 percent, not 100. The rest goes to admin, marketing, proposals, and learning, all necessary work that simply does not appear on an invoice.

It is late Friday afternoon. Lars closes his invoicing app. This month he billed 78 hours. He knows he worked closer to 150. There was the proposal for the Rotterdam agency that did not land, two days of admin and chasing late invoices, a half day rebuilding his portfolio site, an unpaid intro call that ran long. The 78-to-150 split feels wrong, but he has no way to know whether it is wrong. That ratio has a name, and once you know it, the picture stops being personal and starts being a number you can work on.

What counts as a healthy utilization rate

For a solo freelancer, 50 to 70 percent is the realistic healthy band. Most reference numbers come from agency benchmarks, where individual consultants run at 70 to 85 percent because someone else handles their pipeline. You do not have that someone else. From looking at year-end numbers across a few dozen solo freelancers, most months for most people land between 55 and 65 percent, and that is fine.

What lives in the other 30 to 50 percent is not waste. It is the part of self-employment that an agency would call overhead and bill back to a client through a markup. Proposals that do not close. Bookkeeping. The hour your accountant needs once a quarter. The afternoon you spent learning Figma autolayout because the next project needs it. Pretend it does not exist and you end up pricing as if every hour at your desk is billable, which it never is.

Why chasing 100 percent ends in burnout

Noor ran at 90 percent plus for a full quarter. She was waiting on an extension from her biggest client and decided she could not afford a slow week, so she squeezed sales calls into evenings and let her newsletter drift. The extension came through. Then it ended. Her pipeline was empty for eight weeks because nothing she had not done in March could close in April.

This is a textbook case of the planning fallacy combined with availability bias: a known contract feels safer than imagined future work, so the brain keeps weighting the known one heavier than it should. It does not feel like a mistake while you are doing it. It feels like dedication. The cost arrives one quarter late, which is exactly when it is hardest to connect to the cause.

Running consistently above 80 percent for more than four to six weeks is a leading indicator of a bad next quarter, not a good current one. Marketing is the work that pays in 60 to 90 days. If you stop now, you do not see the gap now.

What utilization tells you about your hourly rate

Most freelancers price their rate as if it were 100 percent utilization, then wonder why the year-end number is short. The math is simple.

Say your target is 70,000 euro a year. A 40-hour week across 46 working weeks (subtract holiday, sick days, and a quiet week or two) is 1,840 working hours. At 60 percent utilization, that is 1,104 billable hours. To hit 70,000 euro you need roughly 63 euro per hour. At 50 percent, the same target needs 76 euro per hour. At 40 percent, 95 euro.

The honest version: your hourly rate is not what you charge per hour. It is what you charge per hour times the share of hours that actually get charged. If you have not done this calculation, do it before the next rate conversation. It changes which number feels expensive.

The formula and a worked example

The formula is one line. Billable hours divided by total working hours, times 100.

Roos worked 152 hours last month. Of those, 94 ended up on a client invoice. 94 divided by 152 is 0.618. Times 100, that is 62 percent. Healthy. Not a number to panic about, not a number to celebrate, just a baseline she can compare against next month.

A month above 70 percent and Roos knows she has under-invested in sales. A month below 45 percent and she knows either a project stalled or her admin ballooned. The number itself is less useful than the change in the number over time.

Billable hours versus total working hours

Billable hours are time spent on a client deliverable that ends up on an invoice. Total working hours are everything you do for the business, including the unbillable categories. The two are not the same as hours at your desk.

A ten-minute scroll through your phone is not working hours. A 90-minute proposal for a client who never signed is. Time you spent on a feature your client asked for and then refused to pay for is billable hours that became non-billable hours, which is its own painful category. The honest line is whether the activity is for the business. If yes, it counts toward total working hours. If it ends up invoiced, it also counts toward billable. The gap between the two is your utilization gap.

What non-billable time actually looks like

There are four buckets of non-billable work that every solo freelancer has, whether they track them or not.

• Admin: invoicing, bookkeeping, VAT filings, expense receipts, contracts, chasing late payments. Roughly 10 percent of total working hours for most people.
• Sales: proposals, intro calls, follow-ups, scoping documents, the back-and-forth that turns a lead into a signed agreement. Often the biggest non-billable category, around 15 percent.
• Marketing: portfolio updates, content, newsletter, network maintenance, the conference you went to in March. Roughly 10 percent.
• Learning: courses, reading, deliberate practice, the afternoon you spent breaking and fixing something to understand it. Roughly 5 percent.

Add those up and you land at 40 percent non-billable, which puts utilization at 60 percent. That is not a coincidence. That is what a healthy solo practice looks like when you actually count the hours instead of pretending they do not exist.

Tracking utilization without a spreadsheet

A spreadsheet works, but most freelancers stop maintaining it by week three. The version that survives is simpler: tag every task as billable or not as you create it, log time as you go, look at the ratio at the end of the month.

The trap is retroactive tagging. Tom tried to reconstruct his March hours from calendar invites and bank statements and ended up with a number he did not trust. So he switched to tagging in the moment. The first week felt fussy. By week three he barely noticed it. By the end of the month he had a number that meant something, because every task had been classified by the person who actually knew what it was.

This is where a planner that treats billable hours as a first-class concept helps. In TaskBerry you can see at a glance how many billable hours are left in your week, which is the question you usually want to answer before deciding whether to take a new call or block tomorrow morning for the proposal that has been sitting open for a week. That is also where this connects to the deeper capacity question: utilization is what happened, capacity is what you actually have available, and the two need to agree before your week makes sense.

A small distinction worth holding onto: utilization rate is not your billable rate. Your billable rate is what you charge per hour. Your utilization rate is what fraction of your hours you charge for. Multiplying them is what tells you your real effective hourly rate, which is the number the tax office and your savings account both care about.

What the number does not do

Knowing your utilization rate does not raise your rate, win you proposals, or tell you which clients to fire. It is a measurement, not an intervention. TaskBerry can show you the picture in close to real time, but it will not retroactively fix a month you forgot to log. If you do not tag tasks billable as you go, the month-end number is a guess, and a guess about your own income is worse than no number at all because it feels authoritative.

The other thing the number will not do is account for the work you are doing for free on purpose. A discounted rate for a long-term client, a project you took because the case study is worth more than the fee, an hour written off to keep a relationship: those are real strategic choices, and a raw utilization number flattens them. Look at the trend, not the single month. A 48 percent month after a 64 percent one is a story, not a verdict.

What to do with your number this month

Tom tagged his tasks for one month and got 48 percent. Not great. The instinct was to work more hours. He resisted it, raised his rate from 65 to 80 euro per hour at the next quarter, and held his hours roughly steady. His billable hours fell slightly. His revenue went up. His utilization rate barely moved, which was the point: the lever was not the share of hours, it was the price of each one.

That is the most common useful action a utilization number prompts. Not "work harder," which is what the instinct says. Usually "charge more for the work that is already billable," sometimes "kill the unpaid scope creep on Client X," occasionally "the marketing has been zero for two months, block a half-day this week."

Tag your tasks for a month. Look at the number once, at the end. Decide one thing based on it. If you want a clean place to do that without a spreadsheet, try the demo board or see what a month of tracking costs you. If you want the longer read on how this connects to weekly planning, realistic work hours for a freelancer is the next stop.
