Most freelancers pick a rate by looking at what others charge, rounding up, and hoping. The result is a number that feels right but isn't connected to what it actually costs to run your business, pay your taxes, and have a life. This page is a calculator you can use right now — no signup, no email wall — to find the hourly rate that actually covers your costs and pays you what you're worth.
The math takes five minutes. The honesty it requires takes longer.
The formula
Your minimum hourly rate is the number that covers your target income, your business costs, your taxes, and the reality that you can't bill every hour you work.
Hourly Rate = (Target Income + Business Costs + Tax Buffer) ÷ Billable Hours Per Year
That's the whole formula. The work is in getting the three inputs honest. The interactive calculator below does the math for you — enter your numbers and see your rate update in real time.
Covers self-employment tax (~15.3% in the US) plus your marginal income tax rate. Use 1.3 for low-tax areas, 1.4 for high-tax.
The billable hours reality check
The number that makes or breaks the calculation is your billable hours. Most freelancers assume they can bill 2,000 hours a year (40 hours × 50 weeks). That's a fiction.
A realistic year for a full-time freelancer:
| Category | Hours |
|---|---|
| Total working hours (40/wk × 50 wks) | 2,000 |
| Minus: vacation and holidays (3–4 weeks) | −120 to −160 |
| Minus: sick days and personal time (5–10 days) | −40 to −80 |
| Minus: admin, invoicing, bookkeeping (2–3 hrs/wk) | −100 to −150 |
| Minus: business development and marketing (3–5 hrs/wk) | −150 to −250 |
| Minus: professional development and learning (2–4 hrs/wk) | −100 to −200 |
| Minus: context-switching and breaks | −100 to −200 |
| Realistic billable hours | ~1,000–1,300 |
The honest range for a full-time solo freelancer is 1,000–1,200 billable hours per year. Not 2,000. Not 1,600. If you're billing 1,200 hours, you're doing well. If you're billing 1,000, you're normal.
If you track your time — and the how-to guide on tracking billable hours walks through this — you'll know your real number within a month. Until then, use 1,100 as a conservative starting point in the calculator above.
Worked example
Let's run the numbers for a realistic freelancer — a designer in the US, mid-career, working from home:
| Input | Value |
|---|---|
| Target income (take-home) | $80,000 |
| Tax multiplier (1.35) | × 1.35 |
| Grossed-up target | $108,000 |
| Business costs (total) | $18,000 |
| Combined revenue needed | $126,000 |
| Billable hours | 1,100 |
| Minimum hourly rate | $115/hr |
If that number feels high, it's because most freelancers underprice — not because the math is wrong. A $115/hr rate on 1,100 billable hours produces $126,000 in revenue, which after $18,000 in costs and ~$28,000 in taxes leaves $80,000 in take-home. That's a normal professional salary, not a windfall.
Add 15% for profit margin and the billing rate becomes $132/hr. Round to $135 or $140 for a clean number that's easy to quote.
Your minimum rate is the break-even number. The profit margin on top accounts for:
- Risk — projects that go sideways, clients who don't pay, dry spells between engagements.
- Reinvestment — upgrading equipment, hiring help, investing in better tools.
- Growth — the margin that lets you raise your rate next year without renegotiating every contract.
Common mistakes
Using 2,000 billable hours. A full-time freelancer bills 1,000–1,200 hours, not 2,000. The rest is admin, business development, breaks, vacation, and sick days. If you use 2,000, your rate will be ~40% too low and you'll wonder why you're working 60-hour weeks and still can't make rent.
Forgetting health insurance and retirement. These are the two costs that an employer used to cover. In the US, a decent health plan runs $400–$1,000/month. Retirement contributions are another $250–$800/month. If these aren't in your business costs, your rate is subsidizing them from your take-home pay.
Setting the rate once and never reviewing it. Your costs change. Your billable hours change. Your skills improve. Review your rate annually — recalculate with updated numbers, and raise your rate if the math says you should. The freelancers who stay at the same rate for three years are the ones who gradually go broke on paper.
Not tracking actual billable hours. The calculator gives you a number based on an assumption. Your actual billable hours are a fact you can measure. Track your time for one month, count the billable hours, annualize, and compare to what you assumed. If the real number is lower, your rate needs to go up.
What to do with your rate
Once you have your number, three things follow:
Track time against it
Your rate is only real if the hours behind it are accurate. If you bill 30 hours but only tracked 20 — because you forgot to start the timer during the email thread — you've effectively cut your rate by a third. Track billable hours honestly, including communication and admin time, and your effective rate will match your headline rate.
Set estimates against it
When you quote a project, multiply your hourly rate by the estimated hours. That's the floor of your quote — anything below it means you're donating time. Ayron's estimate-vs-actual tracking lets you watch the project against its estimate in real time, so you know before the project ends whether the rate you quoted is the rate you're actually earning.
Invoice at your rate
The rate in your calculator should be the rate on your invoices. Not a discounted "friend rate," not a "this client might leave if I charge full price" rate. If the number is honest, charge it. Ayron's invoicing turns tracked hours into branded PDFs with Stripe payment links — the rate you set is the rate that appears on the line items.
FAQ
How do I calculate my freelance hourly rate? Add your target annual income (grossed up for taxes) to your annual business costs, then divide by your realistic billable hours per year (typically 1,000–1,200 for a full-time freelancer). Add 10–20% for profit margin. Use the interactive calculator above to do the math automatically.
What are billable hours vs working hours? Working hours are every hour you're at your desk. Billable hours are the subset you can invoice to clients. A full-time freelancer works ~2,000 hours but bills ~1,000–1,200 — the rest is admin, business development, vacation, sick days, and breaks. Using 2,000 as your billable number is the most common rate-calculation mistake.
Should I charge different rates for different clients? You can, but the calculator gives you your floor — the rate below which you're losing money. Above that, market rates and client value set the ceiling. A client with high strategic value might get your floor rate; a commodity engagement should pay your full rate or more. The key is never going below the floor.
How often should I recalculate my rate? Annually, at minimum. Recalculate when your costs change significantly (new health insurance, new equipment), when your billable hours shift (more or less admin), or when your skills and market value have clearly improved. The freelancers who never raise their rate are the ones whose real income quietly declines with inflation.
Is this calculator free to use? Yes. No signup, no email, no paywall. Enter your numbers in the calculator above and you'll have your rate in under a minute. If you want a tool that tracks the hours behind that rate and turns them into invoices, Ayron is built for it — Free to start, Pro is $12/mo annual.
Does this work outside the US? The formula works anywhere. The tax multiplier is the only US-specific input — adjust it for your country's self-employment tax rate and income tax bracket. The billable hours estimate is universal: a full-time freelancer anywhere bills ~1,000–1,200 hours per year.
