Setting freelance rates is one of the hardest parts of going independent — and the most common mistake is undercharging. Most new freelancers simply convert their old salary into an hourly wage, forgetting that an employee's salary covers only part of their real cost. A freelance rate calculator fixes this by working backwards from the income you actually want, adjusted for the hours you can realistically bill and the overhead freelancers carry.
Here's the math behind it: first, your billable hours are almost always lower than your working hours. Client work, calls, and revisions are billable — but proposals, marketing, invoicing, learning, and admin are not. Most freelancers bill 15–25 hours a week. Then comes overhead: self-employment tax (15.3% in the US), income taxes, health insurance, retirement savings, software, and business expenses. A 25–40% overhead factor is typical, which is why a $40/hour salary equivalent often translates to $65–$80/hour freelance.
This calculator combines both adjustments. Enter the annual income you want to keep, your honest weekly billable hours, how many weeks a year you work (account for vacation and holidays — 48 is a realistic default), and your overhead percentage. It then computes the gross revenue you need and divides it by your annual billable hours to give you the exact rate to charge.

How to use the Freelance Rate Calculator
- Enter your target annual income — what you want to keep after taxes and expenses.
- Set your billable hours per week — hours clients actually pay for, not total working hours.
- Set weeks worked per year — 48 accounts for four weeks off; use 52 if you never stop.
- Adjust the overhead percentage — 25% is a solid starting point covering taxes, insurance, and expenses.
- Click Calculate My Rate to see your required hourly rate plus weekly, monthly, and annual revenue targets.
Rate-setting tips that actually work
- Be honest about billable hours — using 40 when you bill 18 silently cuts your income by more than half.
- Your first rate is a floor, not a ceiling: experienced freelancers raise rates 10–20% each year as demand grows.
- Compare your result against market rates for your skill — if the market won't pay it, trim expenses or raise billable hours rather than working for less.
- Consider a project rate equivalent: multiply the hourly figure by your estimated hours to quote fixed-price projects without undercutting yourself.
Why freelancers must charge more than employees
An employer pays roughly 1.25–1.4× your salary in benefits, payroll taxes, and paid time off — money freelancers never see. On top of that, freelancers lose 10–20% of working time to non-billable tasks and absorb all business risk: dry spells, late-paying clients, and zero paid vacation. The overhead percentage in this calculator bundles all of it into one number, so the hourly rate it returns is the one that keeps your income whole after reality takes its cut.
Frequently asked questions
How do I calculate my freelance hourly rate?
Start with your target annual income, divide by your realistic billable hours per year (billable hours per week times weeks worked), then divide by one minus your overhead rate. Overhead covers self-employment tax, health insurance, retirement savings, and unpaid admin time. For example, an $80,000 target, 20 billable hours per week, 48 weeks, and 25% overhead gives a rate of about $111 per hour.
Why do freelancers charge a higher hourly rate than an employee's salary equivalent?
Employees get paid for non-billable time, receive benefits like health insurance and retirement contributions, get paid time off, and only pay half of Social Security and Medicare taxes. Freelancers must cover all of that from their billings — typically 25–40% overhead — which is why a $40/hour salary equivalent often translates to $65–$80/hour freelance.
What is a realistic billable utilization rate for freelancers?
Most freelancers bill 15–25 hours per week even when working a full schedule, because the rest goes to marketing, proposals, invoicing, learning, and admin. New freelancers often manage only 10–15 billable hours. Enter your honest billable hours — not your total working hours — for an accurate rate.
How much should I add for taxes as a freelancer in the US?
A common rule of thumb is to set aside 25–30% of gross income for federal, state, and self-employment taxes (15.3% self-employment tax alone). The overhead percentage in this calculator is a simpler shortcut: enter the share of each dollar you expect to lose to taxes, insurance, retirement, and business expenses.
