Most freelancers discover their real hourly rate the hard way -- by tracking all their hours for a week and dividing total income by total time worked. The resulting number is usually 25-40% lower than expected.
The Formula Most Freelancers Use (and Why It Is Wrong)
The standard advice: decide what annual income you want, divide by hours you plan to work, and that is your rate. Want $100,000 working 40 hours/week for 48 weeks? That is $52/hr.
The problem is that this assumes every hour is billable. In practice, freelancers spend significant time on work that never appears on an invoice: prospecting, proposals, client communication, admin, bookkeeping, learning, and context switching. Industry data consistently shows freelancers bill 60-75% of the hours they actually work.
If you bill 65% of your hours, that $52/hr rate requires charging $80/hr for the billable portion. The gap between $52 and $80 is the difference between hitting your income target and falling 35% short.
The Real Formula
A more accurate calculation:
- Target annual income (after taxes) -- what you want to take home
- Add your effective tax rate -- if you want $80k after tax at 30%, gross target is ~$114k
- Add annual business expenses -- software, hardware, insurance, accounting: say $8,000
- Total revenue needed = $114,000 + $8,000 = $122,000
- Calculate available billable hours -- 52 weeks minus vacation (4w) minus buffer (2w) = 46 weeks x 40 hrs x 65% billable = 1,196 billable hours
- Hourly rate = $122,000 / 1,196 = $102/hr
Finding Your Billable Ratio
The most important variable in this formula is your billable ratio. Most freelancers guess it, and most guess high.
To find your real ratio, track all your time for two full weeks. Not just client work -- everything: admin, email, proposals, research, learning. Divide billable hours by total hours.
Common findings:
- Email and Slack: 5-8 hrs/week
- Proposals and prospecting: 3-5 hrs/week
- Admin and bookkeeping: 2-3 hrs/week
- Context switching between clients: 30-60 min per switch
These categories consume 25-40% of the average freelancer work week.
If your ratio is below 60%, the problem is usually structural -- too much prospecting (not enough recurring clients), too many small projects (high per-project overhead), or too many tools creating unnecessary admin.
Using Time Data to Improve Your Rate
Once you have accurate time data by project and category:
- Per-project time logs show which types of work are most profitable
- You can identify which project categories have systematically lower billable ratios
- Scope creep becomes visible: if "quick" projects consistently take 40% longer than quoted, that is a pricing signal
This lets you shift your client mix toward more profitable work and set clearer scope boundaries.
When to Raise Your Rates
Four signals:
- Your effective hourly rate has dropped even though your quoted rate has not -- non-billable work is growing
- You are fully booked -- demand exceeding supply is the clearest market signal to raise prices
- Consistent project overruns -- if every project takes 30% longer than quoted, your rate needs to be 30% higher
- You have not raised rates in over a year -- inflation, experience, and speed improvements all justify annual adjustments
How to Communicate a Rate Increase
Give existing clients 30-60 days notice. Frame it around value: "My rates are increasing to $X effective [date]. This reflects [updated skill set / increased demand / annual adjustment]." Do not apologize or over-explain.
For new clients, simply quote the new rate. If a prospect objects, negotiate scope -- not rate.
Expect to lose a small percentage of clients. The ones most sensitive to price increases often consume the most non-billable time in communication and revision cycles.
Flowly tracks time per task automatically, so you can calculate your true billable ratio without a spreadsheet. Free plan available.
