Billable vs Non-Billable Hours: A Freelancer's Guide to Tracking Both
Every freelancer's week contains two kinds of hours: the ones a client pays for and the ones nobody does. The first kind gets all the attention, because it turns directly into invoices. The second kind, the proposals, the admin, the chasing, tends to vanish without a trace. And that's a problem, because the unpaid half of your week is quietly deciding how much the paid half is really worth.
The number that settles it is your utilisation rate: the share of your working week that actually earns. Get that wrong and every pricing decision you make afterwards inherits the error.
What are billable hours?
Billable hours are time spent on work a client has agreed to pay for. If the task exists because of a client's project and falls within the scope you agreed, it's billable. For most freelancers and contractors that includes:
- The production work itself: designing, writing, coding, consulting, building.
- Meetings and calls about the client's project, including kick-offs and reviews.
- Research and planning specific to the brief.
- Revisions and amendments that fall within the agreed scope.
- Project communication: the emails, updates and check-ins the work requires.
- Travel for the project, where your contract says it's chargeable.
The test is simple: would this work exist without this client? If the answer is no, and it's inside the scope you agreed, you're on billable time.
What are non-billable hours?
Non-billable hours are the work that keeps your business running but doesn't appear on any invoice. It's still work, and it still takes real hours out of your week:
- Marketing yourself: your website, portfolio, social presence and networking.
- Writing proposals, quotes and pitches for work you haven't won yet.
- Invoicing, bookkeeping, tax returns and chasing late payments.
- General admin and the email that belongs to no project in particular.
- Learning: courses, reading and keeping your skills current.
- Fixing your own mistakes, which most contracts (and most consciences) treat as unchargeable.
None of this earns directly. All of it is essential. That tension is exactly why it needs to be visible on your timesheet rather than hidden off the books.
The grey areas (and how to handle them)
Some time refuses to sort itself neatly. A "quick question" email thread that eats half an hour. A call that's half project update, half sales pitch for the next phase. Travel to a client's office. Revisions that creep past the original scope.
There's no universal rule, but there is a universal fix: decide up front, write it into your contract or proposal, and apply it consistently. Common conventions are to bill project communication but not general relationship chat, to bill travel at a reduced rate or an agreed cap, and to flag out-of-scope revisions before doing them rather than arguing about them afterwards. Clients rarely mind where you draw the line; they mind discovering it after the invoice arrives.
Why you should track both
It's tempting to track only the hours you can charge for. Plenty of freelancers do, and their timesheets look wonderfully profitable right up until they wonder why the bank balance disagrees. Tracking non-billable time alongside billable gives you:
- An honest picture of your real working week, not just the invoiced part of it.
- Evidence for pricing. If every "small" project brings four hours of unpaid admin, your rate needs to cover that.
- Early warning about clients whose projects quietly sprawl into unpaid territory.
- A basis for capacity planning: you can't take on twenty billable hours if admin already fills fifteen of your forty.
Your hourly rate has to fund your whole week, not just the hours on the invoice. You can only price that properly if you can see the whole week. We've covered the record-keeping side of this in why timesheets matter for freelancers.
How to calculate your utilisation rate
Your utilisation rate is the percentage of your working time that's billable:
Utilisation rate = (billable hours ÷ total hours worked) × 100
Say you worked 40 hours last week and 26 of them were billable. That's 26 ÷ 40 × 100, a utilisation rate of 65%. For an established freelancer, 60% to 80% is a healthy band, and it's roughly where agencies pitch their delivery teams too. Meaningfully below 50%, and admin or unpaid work is eating the business (or you're in a deliberate marketing push, which is fine as long as it's deliberate).
Utilisation also reveals your effective hourly rate, which is the number that actually pays your bills. At £50 an hour and 65% utilisation, a 40-hour week earns £1,300, which spread across all 40 hours worked is £32.50 an hour. That's the figure to compare against a salary, and it's why chasing a higher headline rate and protecting your utilisation are the two levers that matter most.
How to track billable hours in five steps
1. Define billable with each client up front
Agree what's chargeable before the project starts: the work, the meetings, the revisions, the travel. Put it in the proposal or contract. Every grey area you settle now is an awkward email you won't send later.
2. Set the rate on the project, not the entry
Keep one rate per project (or per client), stored in one place. Rates scattered across individual timesheet rows drift out of date and contradict each other. In VibaCloud this is enforced by design: the project carries the rate and the billable flag, and every entry tagged to it inherits both automatically.
3. Mark every entry billable or not as you log it
Classify time when you record it, while the context is fresh. Deciding three weeks later whether that call was chargeable is guesswork, and guesswork usually resolves in the client's favour.
4. Record non-billable time at zero value, not zero hours
Non-billable lines belong on the timesheet with their real hours and a value of £0. They never touch an invoice, but they keep your week honest and your utilisation rate calculable.
5. Review your utilisation weekly
Once a week, glance at the split: billable hours, non-billable hours, and the value of the week. Five minutes is enough to spot a slide before it becomes a quarter. A weekly summary that shows the billable and non-billable split at the top of your timesheet (VibaCloud's does exactly this) turns the review into a glance, and for the longer view VibaCloud's time tracking reports chart the same split across months.
Can you shrink the non-billable pile?
Somewhat, and it's worth trying, but don't aim for zero. A few honest wins:
- Batch your admin into one or two slots a week instead of letting it perforate every day.
- Template the repeat offenders: proposals, onboarding emails, invoice layouts.
- Automate the tracking itself. If your timesheet builds from your calendar and your invoices build from your timesheets, hours of monthly admin disappear.
- Price recurring non-billable work into your rate rather than resenting it.
And remember that 100% utilisation isn't the goal. A freelancer with no time for marketing, learning or proposals is one project ending away from an empty pipeline. The aim is a deliberate split, not a maximal one.
Key takeaways
- Billable hours are agreed, in-scope work for a client; non-billable hours are everything that keeps the business running.
- Settle grey areas (meetings, travel, revisions) in the contract, before they cost anything.
- Track both kinds of time; record non-billable hours at zero value rather than leaving them off.
- Utilisation rate = billable hours ÷ total hours × 100. Between 60% and 80% is a healthy range for most established freelancers.
- Your effective hourly rate (earnings spread across all hours worked) is the number to judge your pricing by.
- Reduce non-billable time with batching, templates and automation, but never to zero.
Frequently asked questions
Are meetings billable hours?
Meetings about a client's project are usually billable: kick-offs, reviews, working sessions and progress calls all exist because of the project. Internal meetings, networking and sales conversations with prospective clients are non-billable. If a call mixes both, split it honestly or agree a convention with the client in advance.
Is travel time billable?
It depends on your contract, so agree it before the project starts. Common arrangements are billing travel at your full rate, billing it at a reduced rate, capping the chargeable travel per trip, or treating it as non-billable but charging expenses. Consistency matters more than which option you pick.
What percentage of my hours should be billable?
Most established freelancers land between 60% and 80% billable, and agencies typically target a similar range for delivery staff. Below 50% usually means admin or unpaid work is crowding out paid work. Aiming for 100% is a mistake: it leaves no time for marketing, proposals or learning, which is how pipelines run dry.
Should non-billable hours appear on the invoice?
No. The invoice shows billable work only. Non-billable time lives on your timesheet at zero value, for your own visibility. Some freelancers add an occasional 'no charge' line to an invoice to make goodwill work visible to the client, which is fine, but it's a communication choice, not bookkeeping.
How do I calculate my utilisation rate?
Divide your billable hours by your total hours worked and multiply by 100. If you worked 40 hours and 26 were billable, your utilisation rate is 65%. Track it weekly and watch the trend rather than obsessing over any single week.
Does non-billable time affect what I should charge?
Directly. Your rate has to fund your whole working week, not just the invoiced hours. At 65% utilisation, every billable hour needs to earn roughly one and a half hours of living costs, which is why freelance hourly rates are (and should be) higher than the equivalent salary divided by working hours.
