Quick answer
A freelance project quote is more than hours times your hourly rate, because it also has to cover non-billable overhead, business costs and profit. In the calculator's own example, 60 hours at $50/hr with 20% overhead, 15% costs, 15% margin and $100 of fixed expenses gives a recommended quote of $4,893, against $3,000 from hours times rate alone.
How this calculator works
Most freelancers price a project by multiplying estimated hours by an hourly rate and calling it a day. That number is not a quote — it is your labour cost. A real quote has to also pay for the hours nobody bills (emails, calls, revisions, project management), the cost of running your business (software subscriptions, hardware, self-employment taxes), and profit on top. This calculator builds the price in four visible steps, so you can see exactly where every dollar of the final number comes from — and defend it if you ever need to.
× (1 + Business costs%) × (1 + Profit margin%)
Effective hourly = Quote ÷ Estimated hours
Quote range = Quote to the same build at (Overhead% + 15 percentage points)
Each percentage compounds on the running subtotal, in order: labour → overhead → fixed expenses → business costs → margin. Fixed expenses go in before the costs and margin multipliers on purpose — money you spend on a project (licenses, stock assets, a subcontractor) deserves tax coverage and profit too, or you are reselling it at a loss.
Why hourly × hours underprices projects
Hours-times-rate assumes every hour of the project is production time. It rarely is. Two vendor pages put numbers on non-billable time; neither is a measurement behind this calculator's figures, so each is attributed. SoloHourly, a time-tracking and pricing tool for freelancers, publishes a guide by its creator (updated April 2026) that advises targeting a 50–65% utilization rate, meaning billable hours as a share of all hours worked, and calls 20–30 billable hours a week the "Goldilocks Zone", with 25 the ideal weekly target and 30 the absolute upper limit for most freelancers. Clockify, a time-tracking vendor, reports in a statistics round-up that in a 2024 Freelancer Map survey 47% of freelancers spent 10–20% of their time on administration such as accounting and client acquisition, 37% less than 10% and 16% more than 20%, and it reads this as almost half of freelancers spending about six hours a week on administration and accounting. The kickoff call, the "quick question" emails, the third round of feedback, chasing the invoice — none of it appears in your hours estimate, and all of it is real work the project consumes.
There is also a structural problem: a fixed-price project transfers estimation risk from the client to you. If you quote bare labour and the project runs 20% over, you just worked that extra 20% for free. The overhead buffer is not padding; it is the price of carrying that risk.
What overhead really includes
The two percentage buffers cover different things, and it helps to keep them separate:
Non-billable overhead (default 20%) is time: discovery and kickoff calls, status updates, writing the brief back to the client, revisions inside the included rounds, file handover, and the context-switching tax of picking the project back up after every interruption. The 20% default is this calculator's own choice, not a result from research: it adds 0.2 hours of project time for every hour you bill, so about 83% of the hours on the project are billable (1 ÷ 1.20). SoloHourly's worked example is the same size: a 30-hour website project that also took 6 hours of discovery calls and proposal writing, revision emails and client management, invoicing, contract and file handoff (6 ÷ 30 = 20%). If a client is chatty or a project has many stakeholders, enter more. The 15-point step in the quote range takes the default to 35%, where about 74% of the project's hours are billable (1 ÷ 1.35).
A utilization rate such as SoloHourly's 50–65% counts every working hour, including marketing, business development and learning. This field covers only the non-billable time that belongs to one project, so the two numbers are not interchangeable and the calculator does not convert one into the other.
Business costs (default 15%) are money: the Adobe or Figma or hosting subscriptions amortised over your projects, hardware depreciation, payment-processor fees and, if you work in the US, self-employment tax. The calculator computes no tax: this field is a flat percentage you choose, and 15% is its default, not a tax rate.
For scale, US federal self-employment tax. The IRS's self-employment tax page (page last reviewed or updated 27 June 2026) gives the rate as 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, plus a further 0.9% Medicare tax above a threshold that depends on filing status: $250,000 for joint filers, $125,000 for married filing separately and $200,000 for everyone else. IRS Topic no. 554 (page last reviewed or updated 24 September 2026) says the amount subject to the tax is generally 92.35% of your net earnings from self-employment, where net earnings are your gross business income less ordinary and necessary business expenses; that you can deduct one-half of the tax in figuring your adjusted gross income, a deduction the self-employment tax page says affects only your income tax and not the self-employment tax itself; and that the 12.4% part applies only up to a yearly maximum, while all net earnings are subject to the 2.9% part. Multiplied out, 15.3% of 92.35% is 14.13% of net earnings, and that holds only while the Social Security part still applies. Above the yearly maximum only the 2.9% Medicare part is charged (2.9% of 92.35%, or 2.68% of the earnings above it), plus the further 0.9% where it applies. For earnings in 2026 the IRS gives the Social Security wage base limit as $184,500 (IRS Topic no. 751, a page about wages, last reviewed or updated 24 September 2026). The self-employment tax page describes one limit shared by wages, tips and net earnings together, so wages from a job count toward it, and if they reach it on their own none of your net earnings bears the 12.4% part; that page's own sentences still give the 2024 figure. The tax is charged on a year's net earnings, not on a project's price, so it is not on the same base as the business-costs percentage above.
Profit margin (default 15%) is what is left after all of the above — the money that funds slow months, new equipment, and courses. If your "profit" is just your labour rate, you own a job, not a business.
Quote ranges and anchoring — the practical version
The range under the recommended quote is not a cosmetic ±15%. Its low end is the recommended quote at the overhead you entered; its high end reprices the entire build with 15 percentage points more overhead, which at the default is 35%. The 15 points are this calculator's own step, not a figure from a study. The range answers a concrete question: what does this project cost if the client turns out to be the chatty kind?
The range also changes how to use it in negotiation. The first number spoken becomes the anchor — everything after it is judged relative to that number — so lead with the top of the range or the recommended number, never below it. If the project stays lean you can concede toward the recommended figure and still be whole; the low end already covers your costs and margin at your own overhead estimate, so treat it as a floor, not a discount.
Two practical habits: first, quote a specific-looking number. Precise figures anchor harder than round ones: the abstract of Janiszewski & Uy (2008) reports five studies in which adjustment away from a numerical anchor was smaller when the anchor was precise than when it was rounded. In worked example 1 below, $4,893 is the precise figure and $5,000 would be the rounded one. Second, if you offer options, offer three: a stripped-down version below your range, the recommended scope at your number, and a premium tier above it, which puts your real price in the middle. The client still sees and chooses every option.
Worked example 1 — a $50/hr web project
A freelancer estimates a small business website at 60 hours at $50/hr, with the default 20% overhead, 15% costs, 15% margin, and $100 of fixed expenses (a premium theme license).
| Step | Calculation | Running total |
|---|---|---|
| Base labour | 60 × $50 | $3,000.00 |
| + Overhead 20% | $3,000 × 1.20 | $3,600.00 |
| + Fixed expenses | $3,600 + $100 | $3,700.00 |
| + Business costs 15% | $3,700 × 1.15 | $4,255.00 |
| + Profit margin 15% | $4,255 × 1.15 | $4,893.25 |
Recommended quote: $4,893. Quote range: $4,893 – $5,488 — the high end is the identical build at 35% overhead. Effective hourly rate: $4,893 ÷ 60 = $81.55/hr. Notice the gap: hours-times-rate said $3,000, and every dollar of the extra $1,893 is accounted for — none of it is arbitrary "padding".
Worked example 2 — a $25/hr design task
A designer quotes a social-media graphics pack: 12 hours at $25/hr, same default percentages, no fixed expenses.
Base labour is 12 × $25 = $300. Overhead takes it to $300 × 1.20 = $360; business costs to $360 × 1.15 = $414; margin to $414 × 1.15 = $476.10. Recommended quote: $476, range $476 – $536 (the same build at 35% overhead), effective hourly $39.68/hr. On small projects the buffers matter more, not less: a single extra feedback round on a $300 job can wipe out the entire profit, and small clients tend to generate proportionally more communication per billable hour, not less.
Practical guidance
Set the hourly rate from the market for your skill, not from what feels safe — the hint on the field says "what an agency or employer would pay" because that is the honest reference point. Track your actuals on two or three projects and feed the real overhead percentage back into the calculator; your own history beats any default. Put the included revision rounds in writing every time (the copied summary does this for you), give every quote an expiry date so stale prices cannot be accepted six months later, and for projects over a few thousand dollars, split payment into milestones — a deposit before work starts is the single most effective protection a freelancer has.

FAQ
Why is the quote higher than my hours times my hourly rate?
Hours × rate only covers the time you spend producing the work. It ignores non-billable time (emails, calls, revisions, project management), the cost of running your business (software, taxes, hardware), and profit. The calculator layers those on top so the price covers the whole project, not just the typing.
What overhead percentage should I use?
20% is this calculator's default, not a figure from a study: it adds one non-billable hour for every five hours you bill. If a project drags in lots of meetings, feedback rounds or coordination, enter more; the quote range shows the price with 15 percentage points added. Use your own history: compare hours you estimated on past projects with hours you actually spent.
Is the profit margin the same as markup?
Not exactly. This calculator applies the percentage as a markup on your total cost (cost × 1.15 for 15%), which is the simpler convention most freelancers use. A true 15% margin of the final price would be cost ÷ 0.85, which comes out slightly higher. Either is fine as long as you are consistent — the point is that profit is a line item, not whatever happens to be left over.
Should I show the client this breakdown?
No. The breakdown is for you. Clients buy outcomes, not your cost structure, and itemising overhead invites line-by-line haggling. Quote one number (or a small range), describe the deliverables and what is included — revision rounds, timeline, validity — and keep the math private. That is exactly what the Copy quote summary button produces.
How many revision rounds should a quote include?
Two rounds is the common default: one for direction, one for polish. The number matters less than stating it in writing. Unlimited revisions is how a profitable project becomes an unprofitable one, so the copied quote summary always names the included rounds and says extra rounds are quoted separately.
Does this work for currencies other than US dollars?
Yes — the math is currency-agnostic. The percentages behave identically whether you enter rates in dollars, euros, pounds or rupees; only the $ formatting is cosmetic. Enter your rate and fixed expenses in your own currency and read the results the same way.
