Your freelance hourly rate is one of the most consequential numbers in your business yet most freelancers set it by guessing what feels reasonable, not by working backward from what they actually need to earn. The result: they undercharge, burn out, and wonder why profitable months still feel tight.
This guide covers the only formula that works. Use our free Freelance Rate Calculator to run your own numbers as you follow along.
The Freelance Rate Formula
The core formula has four inputs:
- Annual income target what you want to take home after tax
- Annual business expenses software, hardware, insurance, accountant, etc.
- Self-employment tax in the US this is 15.3% on net self-employment income; in the UK it's Class 2 and Class 4 National Insurance
- Billable hours per year realistically 1,000–1,400 for most solo freelancers
Hourly Rate = (Income Target + Expenses + Tax Buffer) ÷ Billable HoursWhy Billable Hours Are Lower Than You Think
A standard working year has around 2,080 hours (52 weeks × 40 hours). But freelancers spend significant time on non-billable work: proposals, admin, accounting, marketing, and professional development. A realistic estimate:
- Subtract 10 days public holidays
- Subtract 15 days annual leave
- Subtract 30–40% for non-billable overhead
That typically leaves 1,000–1,400 billable hours per year. Run your number through our Tax Tracker to see how your income maps to tax liability in real-time.
Factor In a Profit Margin
Your rate should include a 10–20% profit buffer not as profit in the traditional sense, but to cover under-utilised months, business investment, and rate stability. Many freelancers skip this and find they're effectively working at cost.
Should You Charge Hourly or on a Project Basis?
Once you know your hourly floor, project-based pricing is often more profitable. Estimate hours, add a complexity buffer, then present a flat fee. Clients generally prefer predictable costs, and you benefit when you work efficiently. Use our Invoice Generator to bill clients cleanly regardless of pricing model.
Frequently Asked Questions
What is a good hourly rate for a freelancer?
There is no single answer it depends on your discipline, market, and experience level. According to Upwork's Freelance Forward report, median hourly rates range from $28 (entry-level) to $120+ (senior specialists). The rate you need, however, is determined by your own income target and cost base not the market median.
How much should I set aside for self-employment tax?
In the US, set aside 25–30% of every payment to cover federal income tax (10–37% bracket-dependent) plus 15.3% self-employment tax. The IRS self-employment tax guide explains how to calculate quarterly estimated payments.
Can I raise my rate for existing clients?
Yes give at least 30 days notice, frame it as a scheduled review (not a request), and explain any service improvements. Most established clients will accept a 10–20% increase annually.
