The Complete Guide to Freelancer Pricing: Billable Hours, Hourly Rates & Project Pricing
Pricing your freelance work is one of the hardest parts of going independent. Charge too low and you burn out; charge too high and you lose clients. This calculator helps you find the sweet spot by working backward from your target income or forward from your hourly rate, while accounting for the hours you actually get paid for versus the hours you actually work.
The key insight most new freelancers miss: you only get paid for your billable hours. The time you spend on emails, invoicing, marketing, learning new skills, and administrative tasks is real work, but nobody pays you directly for it. Your hourly rate must cover ALL your working time, not just the hours you invoice.
Billable Hours vs Non-Billable Hours
Billable hours (sometimes called 'valid hours' or 'chargeable hours') are the time you spend doing client-facing work that you can invoice: designing, coding, writing, consulting calls, etc.
Non-billable hours include business development, answering emails, accounting, creating proposals, learning, and breaks. A realistic billable percentage for most freelancers is 60-75%. If you assume 100% billable time, you will underprice your services and wonder why you're not hitting your income target.
The Reverse-Engineering Formula
To find your required hourly rate, start with your target net income, add back taxes and business expenses, then divide by your annual billable hours:
1. Start with your desired annual net income (after tax)
2. Add business expenses (software, internet, equipment, insurance)
3. Divide by (1 - tax rate) to get required gross revenue
4. Add a safety buffer (10-20%) for slow months and unexpected costs
5. Divide by your annual billable hours to get your hourly rate
This is the rate you must charge per billable hour to hit your target.
Billable Rate vs Effective Rate
Your billable rate is what you charge clients per hour. Your effective hourly rate is your actual take-home pay divided by ALL the hours you work, including non-billable time.
If you charge $100/hour but only 70% of your time is billable, your effective rate drops to $70/hour. After expenses and taxes, it might be closer to $45/hour. Understanding this gap is critical for setting realistic expectations and pricing with confidence.
Project Pricing vs Hourly Pricing
Hourly pricing is simple but penalizes efficiency — the faster you work, the less you earn. Project pricing (fixed price) rewards expertise: estimate the hours, multiply by your rate, add a buffer of 15-25% for scope creep, and quote that number.
Retainers provide predictable monthly income: a client pays a fixed monthly fee for a set number of hours. They're ideal for ongoing work and help smooth out the feast-famine cycle of freelancing.
+What is a billable hour?
A billable hour is any hour you can directly charge to a client. It includes client-facing work like development, design, writing, and consultation calls. It does NOT include admin, marketing, invoicing, or learning time.
+What percentage of my time is realistically billable?
Most freelancers can sustain 60-75% billable time. The remaining 25-40% goes to business development, admin, communication, and learning. If you're new, start with 60%. As you build systems and repeat clients, you can push toward 75-80%.
+How do I set my hourly rate as a freelancer?
Use the reverse-engineering method: decide your target annual income, add expenses and taxes, add a buffer, then divide by your annual billable hours. This gives you the minimum rate you need to charge. Then compare with market rates for your skill and location.
+Should I charge hourly or per project?
Project pricing is usually better once you can accurately estimate scope. It rewards efficiency and gives clients cost certainty. Hourly pricing works well for ongoing, open-ended work where scope is unclear. Many successful freelancers use project pricing for defined deliverables and hourly for maintenance/consulting.
+What expenses should I include?
Include all business costs: software subscriptions, hardware upgrades, internet, coworking space, insurance, marketing, professional development, accounting fees, and transaction fees. Don't forget health insurance if you're self-employed.
+What is an effective hourly rate?
Your effective hourly rate is your actual net income divided by ALL hours you work, including non-billable time. It's always lower than your billable rate. If your billable rate is $100 but only 70% of your time is billable, your effective rate before expenses is $70.
+How much should I add as a buffer?
A 10-20% buffer is typical. It covers slow months, unpaid time chasing invoices, scope creep, and unexpected costs. For project pricing, 20% is a good default. For annual planning, 10-15% is usually sufficient.
+What is a retainer and how do I price it?
A retainer is a fixed monthly fee for a set number of hours. Price it by multiplying the monthly hours by your billable rate. You can offer a 5-10% discount compared to your hourly rate to incentivize commitment, but only if the predictable income is worth it to you.
+How do taxes work for freelancers?
Most freelancers must pay income tax and often self-employment tax. Set aside 25-35% of every payment for taxes (depending on your country and income level). Check with a local accountant — this calculator uses a flat tax rate for simplicity, but real tax is usually progressive.
+How accurate is this calculator?
The calculator provides precise projections based on your inputs, assuming consistent work throughout the year. Real freelance income fluctuates. Use conservative assumptions for planning and treat the result as a target, not a guarantee.
