Billable hours are the hours you spend working directly on a client’s project that you can charge for on your invoice. They are distinct from non-billable hours, which cover everything else you do to run your business: admin, bookkeeping, marketing, and sales. Understanding the difference is essential for pricing your work accurately.
How it works
When you work on an hourly pricing model, you track the time you spend on each client’s tasks. At the end of the billing period, you total those hours, multiply by your hourly rate, and send an invoice.
Not every hour at your desk is billable. Here is how the two categories break down:
| Billable | Non-billable |
|---|---|
| Writing code, copy, or design work for a client | Responding to your own business emails |
| Client meetings about the project | Bookkeeping and invoicing |
| Research related to a client deliverable | Marketing and social media for your business |
| Revisions requested by the client | Writing proposals and pitching new clients |
| Testing and quality assurance | Professional development and learning |
Most freelancers find that only 60 to 70 percent of their working hours are billable. If you work 40 hours a week, roughly 25 to 28 generate direct revenue. This ratio directly affects how you should set your hourly rate. If you price based on 40 billable hours per week but only bill 25, you will consistently earn less than planned.
Why it matters for freelancers
Your billable hour count is the engine of your revenue. If you do not track it, you cannot tell whether you are making money or slowly going broke. Freelancers who track consistently make better decisions about which clients to keep, which projects to raise rates on, and when they have capacity for new work.
Tracking also protects you in disputes. A detailed time log is your best defense when a client questions an invoice.

Example
You are a freelance developer working at $150 per hour. During one week:
- Monday: 5 hours building a client’s checkout flow (billable), 1 hour on bookkeeping (non-billable)
- Tuesday: 6 hours on client work (billable), 30 minutes on a sales call (non-billable)
- Wednesday: 4 hours on client bug fixes (billable), 2 hours writing for your own site (non-billable)
- Thursday: 5 hours on client features (billable), 1 hour invoicing (non-billable)
- Friday: 3 hours on client code review (billable), 2 hours prepping a talk (non-billable)
Total billable: 23 hours. Invoice for the week: 23 x $150 = $3,450. Your effective rate across all 29.5 hours worked is about $117 per hour. Knowing that gap helps you evaluate whether your rate needs to go up.
Common mistakes
Not tracking non-billable time. You cannot optimize what you do not measure. Track everything for at least one month to get a baseline of your true billable ratio.
Billing for every minute. Rounding up every 8-minute task to a full hour will damage client trust. Use 15-minute blocks and be transparent about your rounding policy in your payment terms.
Underreporting billable time. Quick tasks like a 20-minute email exchange about project direction or a 15-minute phone call to clarify requirements are billable. If the work is for the client’s project, log it.
Using billable hours as your only pricing model. Hourly billing works for ongoing or unpredictable work, but for well-defined projects, fixed pricing or milestone payments often serve you better. Read our freelance pricing guide for more on choosing the right model.
FAQ
What is a good billable hour ratio for freelancers? Most freelancers bill between 60 and 75 percent of their working hours. Below 50 percent means too much time on non-billable work. Above 80 percent usually means you are neglecting business development, which leads to feast-or-famine cycles. Aim for 65 to 70 percent.
Should I show clients a detailed time breakdown on my invoice? Yes, especially for hourly work. A line-item breakdown (date, task description, hours) builds trust and reduces disputes. Most invoicing tools, including GetPaidFirst, let you attach time logs directly to your invoices.
How do I track billable hours effectively? Log as you work, not at the end of the day from memory. End-of-day logging underreports by 10 to 20 percent. Start a timer when you begin a task, stop it when you switch. Review your log at the end of each week before sending the invoice.
