Freelance Rate Calculator

Set the salary you want your freelance income to match, the weeks each year you will not be billing, the hours per week you can realistically invoice, your monthly business costs, and a percentage buffer for tax and benefits. The calculator returns the hourly rate that reaches the target, a day rate at eight hours, and the monthly and annual revenue the business needs to invoice. With the defaults the answer is $132 an hour to match a $120,000 salary — well over double the $58 that dividing the salary by 2,080 working hours suggests, and the gap between those two numbers is the point of the tool.

Where billing by the hour comes from

The word freelance is younger than the practice it describes. Sir Walter Scott coined it in Ivanhoe (1820), where "free lances" are medieval mercenaries whose weapons were pledged to no lord and who fought for whoever paid them. The general figurative sense of an unattached man follows in 1864, the application to independent writers by 1882, and the verb "to freelance" only in 1902, but Scott's soldier already carried the defining trait of the modern contractor: no fixed employer, and a price set per engagement rather than a salary.

Selling that time by the hour is younger still, and it did not begin with freelancers. It was built inside law firms. Reginald Heber Smith, who led the Boston Legal Aid Society after leaving Harvard Law in 1914 and became managing partner of the Boston firm Hale and Dorr — now WilmerHale — in 1919, is credited with inventing the billable hour. He brought the scientific-management habit of measuring work into law practice: first in a legal-aid office that had to account for every dollar it spent, then in the private firm he ran, where time records showed what each matter actually cost. Measuring time in six-minute increments — a tenth of an hour — is still the standard unit lawyers bill in. The timesheet began as an internal management tool; billing clients by that same clock came later, spreading through American law firms after the 1950s and dominating large-firm pricing by the 1970s. Every freelancer logging hours against a project is using bookkeeping invented to run a law office rather than to price one.

The costs this calculator grosses up have their own history. In the United States, the Social Security Act Amendments of 1950 first brought non-farm self-employed workers other than professionals into Social Security; farm operators and most professionals followed in 1954, lawyers and dentists in 1956, and self-employed doctors only in 1965. The self-employment tax that hands them both halves of the payroll tax an employer had previously split is the Self-Employment Contributions Act of 1954, Chapter 2 of the Internal Revenue Code. In the United Kingdom, the Inland Revenue press release numbered IR 35, issued in March 1999 and in force from April 2000, targeted the "Friday to Monday" contractor who left a salaried job only to return as a limited company doing the same work for the same firm. Both are reminders that a freelance rate is not a salary with a bigger number bolted on; it carries tax and status rules an employee never saw.

How the rate is built

rate = (salary × (1 + buffer ÷ 100) + overhead × 12) ÷ ((52 − weeks off) × billable hours)

The numerator is the revenue the business must produce in a year. A $120,000 salary grossed up by the default 20% buffer is $144,000, and $900 a month of overhead adds $10,800, for a target of $154,800. The denominator is billable capacity: 52 − 5 = 47 working weeks at 25 billable hours each is 1,175 hours. Dividing gives 154,800 ÷ 1,175 = 131.74, shown as $132. The day rate is eight of those hours, $1,054, and the monthly target is 154,800 ÷ 12 = $12,900 of invoicing.

The monthly target is often the most useful of the four outputs. Rates get negotiated project by project, but a month closing under $12,900 of invoices is a month this business fell behind its own salary.

Why only 25 of your 40 hours are billable

The 25-hour default is not pessimism. Surveys of established freelancers commonly put billable time at half to three-fifths of hours worked. The remainder goes to finding the next project — calls, proposals, portfolio upkeep — and to running the business: invoicing, chasing invoices, bookkeeping, contracts and tax filings. On top of that sits friction nobody budgets for: context switching, unpaid revisions and the dead week between one contract ending and the next starting late.

The weeks-off input absorbs the calendar side of the same problem. Five weeks covers modest vacation plus a few sick days, but many freelancers lose two or three additional weeks a year to gaps they did not choose. Setting billable hours to 40 prices a job, not a business — if a client genuinely fills 40 hours a week for a year with no gaps, what they are buying looks a lot like employment and can be priced closer to a salary.

The 20 percent buffer is a floor

For US freelancers the buffer covers a cost that was invisible on payroll. Self-employment tax is 15.3% on 92.35% of net earnings up to the Social Security cap, $184,500 in 2026, with the 2.9% Medicare half continuing above it. As an employee, your employer quietly paid half of that — 7.65 points — on top of your stated salary. Independent, both halves are yours, though half the self-employment tax is deductible against income tax.

Then come the benefits you now buy at retail. The benchmark marketplace silver plan for a 40-year-old averages $625 a month across the US in 2026 before subsidies, from roughly $400 in the cheapest states to over $1,000 in the dearest, there is no employer 401(k) match, and disability or life cover becomes a line item rather than a payroll perk. Summed honestly, 20 percent roughly covers the mechanical tax shift and little else. Matching the full value of a salaried package tends to need 25 to 35 percent, more in cities with their own payroll-adjacent taxes. Treat the default as the minimum defensible setting.

Day rates, IR35 and how other markets quote

The UK and much of the EU quote contract work per day rather than per hour, typically assuming 7.5 or 8 hours. The day rate here is hourly × 8; if your market assumes 7.5, multiply the hourly output yourself. French freelancers quote a TJM, the taux journalier moyen, and German Freiberufler quote either way; in both markets a stated rate excludes VAT, which is invoiced on top and passed to the tax office.

In the UK, IR35 status matters as much as the rate. Inside-IR35 engagements are taxed like employment, with the fee payer deducting tax at source, and take-home pay can land 20 to 25 percent below an outside-IR35 contract at the same headline rate. That is why a contractor comparing offers should run this calculator on projected take-home rather than the advertised day rate.

Worked profiles at three levels

A junior developer matching $65,000 takes four weeks off, bills 25 hours a week, spends $250 a month on software and insurance, and sets a 25 percent buffer. Target revenue is 65,000 × 1.25 + 3,000 = $84,250 across 48 × 25 = 1,200 hours: $70 an hour, a $562 day. Quoting $30 because it sounds generous next to an old hourly wage funds the client's discount out of the freelancer's own tax bill.

A senior engineer matching $150,000 takes six weeks off, bills 22 hours because referrals, calls and proposals eat the rest, carries $1,200 a month of overhead and buffers 30 percent. Target is 150,000 × 1.30 + 14,400 = $209,400 across 46 × 22 = 1,012 hours: $207 an hour, $1,655 a day.

A consultant running a one-person practice at agency positioning targets $250,000, takes eight weeks out, bills 18 hours a week because writing and positioning generate the leads, spends $3,500 a month on subcontracted design, tooling and marketing, and buffers 35 percent. Target is 250,000 × 1.35 + 42,000 = $379,500 across 44 × 18 = 792 hours: $479 an hour, a $3,833 day.

In every profile the output is a floor, not a price: the rate below which the year fails on its own arithmetic even if every planned hour is billed. Pricing above the floor is a market question: when a four-week project saves a client $200,000 a year, its price should reference that number, not your cost of living. Use the floor to decide which work to refuse, use value to price the work you accept, and rerun the inputs each January, because overhead and the buffer both drift upward.

Frequently asked questions

What hourly rate replaces a $120,000 salary?

About $132 an hour under realistic assumptions: five weeks a year not working, 25 billable hours a week, $900 a month of business costs and a 20% buffer for self-employment tax and benefits. The naive division of $120,000 by 2,080 working hours gives $57.69, which is less than half the real answer because it prices none of the downtime, overhead or employer-side costs.

Why is a freelance rate roughly double the salary equivalent?

Three multipliers stack. You bill perhaps 25 of a 40-hour week, which alone nearly doubles the rate. Your former employer paid 7.65 points of FICA plus benefits on top of your salary, which the buffer has to recover. And the business itself costs money — software, insurance, an accountant, hardware — that salary never had to cover. Each factor is modest; together they double the number.

How many billable hours per week is realistic for a freelancer?

Established freelancers typically invoice 20 to 30 hours out of a 40-to-45-hour working week, roughly 50 to 60 percent. The rest goes to finding work, proposals, invoicing, bookkeeping and the gaps between contracts. Someone in their first year often bills under 20 hours a week while the pipeline builds, which argues for a higher rate, not a lower one.

Is a 20 percent tax and benefits buffer enough in the US?

It is a floor. US self-employment tax alone is 15.3% on most net earnings, and half of that — the 7.65 employer-side points — is a cost you never saw as an employee. Add an individual health plan at $400 to $800 a month and a retirement match you now fund yourself, and matching a salaried package usually needs 25 to 35 percent.

How do UK contractor day rates compare to hourly pricing?

UK contracting quotes per day, usually assuming 7.5 to 8 hours. A £600 day rate across 220 billable days grosses about £132,000 a year before costs. IR35 status moves the net result more than the headline rate does: inside-IR35 engagements are taxed like employment and can take home 20 to 25 percent less than an outside-IR35 contract at the same rate.
