How to Calculate Your Freelance Hourly Rate (A Calm Formula)

Someone asks what you charge, and the honest answer is a number you made up on the spot. It sounded polite. Two projects later you're working evenings to cover taxes the rate never accounted for.

There's a cleaner way to calculate your freelance hourly rate, and it runs in the opposite direction from most freelancers' instinct: don't start from what sounds reasonable — start from what the rate actually has to pay for, then divide by the hours you can genuinely bill. Here's the math, step by step.

How to calculate your freelance hourly rate

The whole formula fits in one line:

What your year costs, divided by the hours you can actually bill.

"What your year costs" is not just rent. It's the take-home you need, plus business expenses, plus taxes, plus the weeks you won't work. "Hours you can actually bill" is not 40 × 52 — it's the smaller, honest number we'll work out below. Everything else is detail.

Step 1: Add up what your year costs

Three buckets, written down separately so you can't quietly lose one:

• Life costs — rent or mortgage, food, health, transport, savings, and a little breathing room. If you're guessing, overestimate; this is the number the whole rate protects.
• Business costs — software, subscriptions, hardware you'll eventually need to replace, insurance, accounting, payment fees. Average the lumpy ones over twelve months.
• Time off — holidays, sick days, and the weeks between projects. We'll handle this in the hours math, but decide now how many weeks a year you genuinely work.

Step 2: Gross it up for taxes

A freelance rate has to survive the tax bill, and self-employed work usually means setting aside a meaningful slice of every invoice. If you don't know your real rate yet, 25–35% is a common starting set-aside for self-employment — adjust to your country and situation, and treat it as its own bucket, not a rounding error.

So the money you must collect in a year is roughly: life costs + business costs, divided by (1 − your tax set-aside). If life and business together come to $50,000 and you set aside 30%, you need to collect about $71,500 before you've paid yourself anything that's actually yours.

Step 3: Count the hours you can honestly bill

This is where most rate calculations fall apart. You will not bill a 40-hour week, and that's not laziness — it's the job. Proposals, email, invoicing, revisions, learning new tools, finding the next client: all real work, none of it paid by the hour. QuickBooks' guide to billable hours sketches a freelance designer's day as 5 billable hours out of 8, and notes freelancers usually aim for 70% billable utilization or more — which, across a realistic working year, lands most solo creatives somewhere around 1,000–1,500 billable hours, not 2,080.

Work out your own version: hours you choose to work per week, minus the hours that go to admin and finding clients, times the weeks you'll actually work. Be unflattering. A rate built on optimistic hours fails quietly, in month three.

A worked example

Here's the whole thing with invented-but-honest numbers (yours will differ — that's the point):

• Life costs: $40,000 a year
• Business costs: $6,000 a year
• Tax set-aside: 30%, so $46,000 ÷ 0.70 ≈ $65,700 to collect
• Working weeks: 45, with 24 billable hours a week → about 1,080 billable hours

$65,700 ÷ 1,080 = roughly $61 an hour. That's the floor. Not a suggestion, not a starting point for negotiation — the number below which work costs you money, or gets paid for by your evenings.

From hourly floor to project fee

Clients rarely buy hours. They buy a finished logo, a working page, a launched product — so convert the floor into project quotes: estimate the honest hours, add 25–30% buffer (work always grows), multiply by your floor, and quote one flat number. Add the deposit and the revision count to the quote itself, not to a later argument.

If the fee that comes out scares you, that's usually the underpricing talking — the fix is the rate, not more hours. And when a client wants it faster, the rush has its own math: we wrote about handling rush requests calmly separately.

Where this fits with Open Margin

If you'd rather have the math on paper, our Freelance Rate Calculator ($7) walks through these exact steps as a fillable worksheet — life costs, billable hours, a rate card you fill once, and a one-page quote builder you copy for every project. There's also a free interactive version if you just want to run the numbers right now. And once the rate is set, the Freelance Client Kit takes over the part that follows: pricing a specific project, writing the proposal, and starting the work.

Common questions

What's a good hourly rate for a beginner freelancer?

One that covers your costs at your real billable hours — which is often higher than a beginner expects. The mistake isn't charging too much early; it's building a rate on 2,000 hours you'll never bill, then discovering the math in month three.

Should I charge hourly or a flat project fee?

Use the hourly number to build the quote, then quote flat. Clients compare finished work, not hours, and a flat fee protects you when the project runs long — as long as the scope and revision count are in writing.

How often should I raise my rates?

When the inputs change: your costs, your tax situation, or a calendar that stays full for weeks. New rates apply to new projects; existing clients get a heads-up, not a surprise.

A rate isn't a personality test or a bet on your worth. It's arithmetic about your life, done once with a clear head — then defended quietly, one quote at a time.
