How many billable hours per week is realistic

For most solo freelancers, 20 to 30 billable hours a week is realistic, not 40. The rest of a full workweek goes to admin, sales, proposals and client email, so roughly half to two-thirds of your working hours end up billable. New freelancers often sit lower, nearer 10 to 18. The ceiling is hours, not projects.

Why 40 billable hours a week does not add up

Full-time hours are not billable hours. Running the business takes a real slice of every week: quoting new work, invoicing, answering email, the sales call that goes nowhere. Only the work a client pays for counts as billable. So aiming for 40 means quietly ignoring the unbillable layer the business actually needs. Half to two-thirds of a working week ending up billable is a good week, not a failing one.

The gap shows up fast when you add real tasks. Block what feels like a normal day: a proposal, two client calls with notes after, a design pass. In TaskBerry each task carries a size. S, M, L, XL and XXL map to 30, 90, 180, 240 and 360 minutes. The proposal is an L at 180 minutes, the two calls are an M each at 90, the design pass is an XL at 240. That is 600 minutes of intent, ten hours, against maybe six billable ones. The day was over budget before it began.

How to tell your week is already full

Set the day's capacity to the hours you actually have, and let the board do the arithmetic. When your sized tasks add up to more than that limit, the overflow turns red, before you start, not at 5pm when there is nothing left to move. That red is the honest signal most planners never give you.

The same check works on a new request. A client asks for one more thing this week. Drop it onto the week as a sized task and watch what happens. If the week goes red, the honest answer is "not this week, or something moves". Capacity turns a vague yes into a visible trade. The /week planner in the demo projects your recurring work across the week so you can run that check before you commit, not after.

How the number changes as you settle in

Where you land in the 20 to 30 range depends on how established you are. New freelancers spend more of the week on sales, setup, and finding the next client, so a realistic figure sits nearer 10 to 18. Someone with a steady client base and settled processes pushes toward the top of the band. Same effort, different overhead.

A designer on three retainers is the clear case. Not short of work, short of hours. The unbillable layer (scoping next month, chasing assets, the weekly check-in email) eats a third to a half of the week. A realistic number is not about working less. It is about not promising retainer hours the week cannot cover.

Where the 20 to 30 rule comes from

The 20 to 30 rule is a rule of thumb, not a statistic. Take a full working week and subtract everything a client does not pay for. What is left is your billable ceiling, and for most solo freelancers it lands in that band. The rule is useful because it sets an honest starting expectation. It is not a target handed down from anywhere.

Your own number matters more than the rule. Utilization, the share of your working hours that end up billable, is worth tracking on its own. We cover it in how utilization rate works for freelancers.

How to work out your own number

Track your actual billable hours for a few weeks and take the honest average. That beats trusting a generic 40. TaskBerry logs time against each client label as you work, so at month end the hours-per-client view shows what was genuinely billable versus admin. That is the number that should shape next week's target.

This is where the tool stops and you start. TaskBerry shows how many hours are real. It will not tell you your rate or how much to charge. Pricing those hours is your call. And a fair warning: estimating focused hours is a skill. The first sizes you set will be optimistic. The ledger corrects them over a few weeks, once you can see planned against actual side by side.

The free plan covers the core of this: task sizes, daily capacity, the red overflow. It caps the AI helper at 3 brain dumps a month and holds you to 3 active client labels, so heavy multi-client tracking is where Pro at 4.95 euro a month earns its place.

How many billable hours fit in a day

Usually four to six hours of focused, billable work, not eight. Concentration is finite, and the day carries meetings, context-switching and admin whether you plan for them or not. That daily ceiling is the reason a day needs a capacity limit too, not just the week. Sizing tasks against the hours you actually have keeps the plan honest before you start.

Berry, the built-in assistant, helps here. Paste a rough list or a client email and get back tidy, time-sized tasks you can drop straight onto the day. It estimates the sizes so you are not guessing at every card.

Start with one week. Size your tasks, set the day to the hours you truly have, and log what you bill against each client. After a month you will have your own number. It will probably be lower than 40 and steadier than you expect. Plan against that, and the yes you give clients is one you can actually keep.
