The year I quit my job to freelance, I priced myself the way almost everyone does: I took my old salary, divided it by 2,080 (40 hours a week times 52 weeks), and called that my hourly rate. Felt fair. Felt easy to defend to a client. A year later I added up what I'd actually earned, divided it by the hours I'd actually worked, including the unpaid ones, and the real number was embarrassingly lower than what I thought I was charging.
I'm not telling you this because I was bad at the work. I was bad at the math. And it's the same math almost every new freelancer gets wrong, because the naive version feels so reasonable that nobody stops to check it.
The Naive Math Everyone Starts With
Here's the formula nearly every freelancer uses on day one: take the salary you used to make, or wish you made, and divide it by a standard work year. Say you were making $70,000. Divide by 2,080 hours and you get roughly $33.65 an hour. Round it up a bit for good measure, call it $35, and that becomes your rate.
It feels solid because it's anchored to something real, your old paycheck. The problem is that $70,000 salary came with a whole list of things attached to it that quietly vanish the moment you go independent, and none of them show up anywhere in that division.
What That Number Forgets
You Don't Bill Every Hour You Work
A salaried 40 hour week is 40 billable hours, as far as your employer is concerned. A freelance 40 hour week is not. Some of those hours go to finding clients, writing proposals, sending invoices, answering emails that lead nowhere, and learning new tools. Most freelancers, once they actually track it, find that somewhere between 60% and 75% of their working hours are billable. The other quarter to third of your time still has to get paid for, just not by a client directly.
Nobody's Paying for Your Time Off
That $70,000 salary assumed paid vacation, paid holidays, and paid sick days. As a freelancer, every day you don't bill is a day with zero income, unless you've built that cost into your rate ahead of time. A salary divided by 2,080 hours has no room in it for the two or three weeks a year you're not working.
Self-Employment Tax Doesn't Exist When You're On Payroll
When you're employed, your company quietly pays half of your Social Security and Medicare taxes. When you're self-employed, you pay both halves yourself, often referred to as self-employment tax, on top of regular income tax. That's a real percentage of your income that a salaried comparison never had to account for, because it was never your line item to begin with.
Business Costs Come Out of Your Rate Now, Not a Company's Budget
Software subscriptions, a laptop upgrade every few years, health insurance you're now buying yourself, an accountant at tax time, maybe a coworking desk. None of this was ever subtracted from your old paycheck because a company absorbed it. Now it comes straight off the top of whatever you bill, before you ever see a dollar of "profit."
- Dividing your old salary by 2,080 hours assumes every hour you work is billable, and it isn't.
- Paid time off, health insurance, and half your payroll taxes were invisible parts of your old salary that don't disappear, they just become your bill to pay.
- Most freelancers bill somewhere between 60% and 75% of the hours they actually work.
- Self-employment tax alone can eat a meaningful chunk of income a salary comparison never accounted for.
- A rate built only from old take-home pay is almost always too low once these gaps are added back in.
Running the Real Numbers
Let's go back to that $70,000 target and rebuild the rate properly instead of just dividing it. First, account for non-billable time: if only 70% of your hours are billable, you need to earn that same $70,000 across fewer actual paid hours, which alone pushes the hourly number up by roughly 40%. Then add back what a salary used to quietly cover: employer-paid payroll tax, paid time off, and health insurance, which together can easily add another 20% to 25% on top. Stack those two adjustments and a rate built off a flat salary division is routinely 30% or more below what it actually needs to be to match the same real income.
Your old salary wasn't just a number, it was a number plus a list of things your employer quietly paid for. Freelancing doesn't remove that list, it just hands you the bill.
This is also why two freelancers doing identical work can have wildly different rates and both be right: one has priced in their real non-billable time and business costs, and the other is still doing the simple division from year one.
Why You Want a Calculator for This, Not a Napkin
Stacking a billable-hours adjustment, a time-off adjustment, a self-employment tax adjustment, and a business expense estimate on top of a target income is exactly the kind of layered math that's easy to get wrong by hand and easy to get right with the correct inputs in the correct order.
Run your own numbers through it once and you'll have an actual figure to defend in a client conversation, instead of a guess inherited from a job you don't have anymore.
How to Set a Rate You Won't Regret in a Year
- Pick a real target income, not your old salary out of habit, but what you actually need or want to earn this year.
- Track your billable percentage for a few weeks if you don't already know it, most people overestimate it badly.
- Add back paid time off by deciding how many weeks a year you actually plan to take unpaid, and spreading that cost across your billable hours.
- Account for self-employment tax and benefits you're now buying yourself instead of assuming they're free, the way they used to be.
- Recalculate at least once a year, since your costs, your billable ratio, and your target income all shift as the work changes.
The number that comes out the other side won't feel as round or as comfortable as the one you started with. That's usually a sign it's closer to correct. The old salary-divided-by-hours number felt comfortable precisely because it was missing pieces, and comfortable is rarely the same thing as accurate when money is involved.
