Day Rate Calculator
Convert between hourly, daily, weekly, monthly, and annual rates. Essential for contractors, freelancers, and anyone comparing compensation.
The Day Rate Calculator is a free, browser-based tool that converts a target annual income into the daily rate a freelancer or contractor must charge. It divides your income goal by the billable days you realistically work rather than by 260 calendar weekdays, so the rate it returns survives holidays, admin time and gaps between contracts.
How Does the Day Rate Calculator Work?
The day rate calculator converts between different compensation periods — hourly, daily, weekly, monthly, and annual — so you can compare rates across different formats and understand what any given rate truly means in practical terms. This is an essential tool for contractors, freelancers, consultants, and anyone evaluating job offers or setting their own pricing. Whether you know your hourly rate and need to quote a day rate to a client, or you are comparing a salaried position to a contract opportunity, this calculator provides instant conversions across all time periods.
The conversion chain starts with your known rate and works outward. If you know your hourly rate, the calculator multiplies by working hours per day to get your day rate, then by working days per week for the weekly rate, and so on up to the annual figure. If you know your annual salary, it works in reverse — dividing by working weeks per year, then by working days per week, and finally by hours per day to arrive at your hourly equivalent. The key variables that affect these calculations are your working hours per day, working days per week, and working weeks per year.
The working weeks per year input is particularly important and often overlooked. A full-time employee working 52 weeks at 5 days per week has 260 working days. But contractors and freelancers typically do not work 52 weeks straight. After accounting for vacation time, public holidays, sick days, and gaps between contracts, most independent workers use 46 to 48 working weeks as a realistic estimate. This means a contractor working 48 weeks at 5 days per week has 240 working days — 20 fewer than a full-time employee. This difference significantly affects the hourly rate needed to match a given annual income.
Formulas
Day Rate = Hourly Rate × Hours Per Day
Weekly Rate = Day Rate × Days Per Week
Annual Rate = Weekly Rate × Working Weeks Per Year
Monthly Rate = Annual Rate ÷ 12
Hourly Rate = Day Rate ÷ Hours Per Day
Weekly Rate = Day Rate × Days Per Week
Annual Rate = Weekly Rate × Working Weeks Per Year
Monthly Rate = Annual Rate ÷ 12
Weekly Rate = Annual Salary ÷ Working Weeks Per Year
Day Rate = Weekly Rate ÷ Days Per Week
Hourly Rate = Day Rate ÷ Hours Per Day
Monthly Rate = Annual Salary ÷ 12
When comparing a salaried position to a contract role, remember that a salaried employee receives benefits such as health insurance, retirement contributions, paid time off, and employer-paid payroll taxes. These benefits typically add 20% to 40% to the true cost of a salaried employee. As a contractor, you must cover these costs yourself. Therefore, to maintain the same effective compensation as a $100,000 salary, a contractor often needs to earn $120,000 to $140,000 annually, which translates to a higher day rate than a simple division might suggest.
Examples
Example 1: $500 Day Rate
A contractor charges a day rate of $500 based on an 8-hour working day. Their hourly equivalent is $500 / 8 = $62.50 per hour. Working 5 days per week, their weekly rate is $2,500. Over 48 working weeks (accounting for 4 weeks of vacation and holidays), their annual equivalent is $2,500 × 48 = $120,000. The monthly equivalent is $120,000 / 12 = $10,000. Their total working days in the year are 48 × 5 = 240 days.
Example 2: $60 Hourly Rate
A freelance developer charges $60 per hour and works 8-hour days, 5 days per week, 48 weeks per year. Their day rate is $60 × 8 = $480. Weekly income is $480 × 5 = $2,400. Annual income is $2,400 × 48 = $115,200, and the monthly equivalent is $115,200 / 12 = $9,600. If the same developer worked all 52 weeks, the annual figure would be $124,800 — a $9,600 difference that illustrates why accounting for non-working weeks matters.
Example 3: $120,000 Annual Salary Conversion
Someone considering leaving a $120,000 salaried position to go freelance needs to know what day rate to charge. Using 48 working weeks and 5 days per week: weekly rate = $120,000 / 48 = $2,500; day rate = $2,500 / 5 = $500; hourly rate = $500 / 8 = $62.50. However, since benefits add approximately 30% to salary value, the freelancer should actually target $156,000 annually, which translates to a day rate of approximately $650 and an hourly rate of about $81.25.
Why Working Weeks Matter for Rate Calculations
The number of working weeks per year is the single most impactful variable in rate conversions, yet it is the one most people overlook. Using 52 weeks instead of a realistic 48 weeks can undervalue your time by 8.3%. For a $500 day rate, that is the difference between $120,000 and $130,000 annual equivalent — a $10,000 gap. Contractors should carefully count the weeks they will not be working: vacation time (2-4 weeks), public holidays (typically 1-2 weeks when spread across the year), sick time (0.5-1 week on average), and gaps between contracts (1-4 weeks depending on your industry and pipeline). A conservative estimate of 46 to 48 working weeks is appropriate for most independent professionals. If you are new to contracting and unsure about your pipeline, using 44 weeks provides an extra safety buffer.
Inside vs Outside IR35: Why Two Identical Day Rates Are Not Worth the Same
If you contract in the UK, the number this calculator gives you is only half the answer, because a £500 day rate inside IR35 and a £500 day rate outside IR35 do not pay the same. Outside IR35, you invoice through your own limited company and the full rate reaches the business before corporation tax and however you choose to draw it. Inside IR35 — or on any umbrella engagement — the figure the agency quotes is an assignment rate, not your gross pay, and several costs are deducted from it before you are paid: employer National Insurance at 15% on earnings above the £5,000 secondary threshold, the 0.5% Apprenticeship Levy, the umbrella's own margin (commonly £15–£30 a week), and rolled-up holiday pay at 12.07% which is your money being handed back to you rather than an extra. Only what remains becomes taxable gross pay subject to PAYE and employee NI.
The practical consequence when you are negotiating: an inside-IR35 assignment rate typically needs to be roughly 20–25% higher than an outside-IR35 rate to leave comparable take-home pay. Quote £500 for both and you have accepted a substantial pay cut on the inside-IR35 one without noticing. So use the calculator above to fix your outside-IR35 day rate first, then uplift it before quoting for an inside-IR35 role. Two further points worth knowing: holiday pay must be checked — ask whether the quoted rate includes or excludes it, because the wording varies by agency and the gap is 12.07%; and from April 2026 responsibility for accounting for PAYE on umbrella workers shifts onto the recruitment agency or end client, which is expected to push non-compliant umbrellas out of the market. Whether a role is genuinely inside or outside is decided by the working practices, not by what the contract says — run the numbers with the IR35 calculator, and see HMRC's off-payroll working guidance and the current employer NI rates and thresholds.

Day Rate vs. Hourly Rate: Which Should You Quote?
The choice between quoting a day rate and an hourly rate depends on the nature of the engagement. Day rates work well when you are dedicating full days to a single client, the scope of work is relatively predictable, or the client prefers budget certainty. Many agencies and large companies prefer day rates because they simplify budgeting and procurement. Hourly rates are better suited for part-time engagements, variable workloads, and situations where you need to track time precisely against different tasks or projects. Some freelancers offer a slight discount on day rates compared to 8 times their hourly rate as an incentive for clients to book full days, which provides more scheduling predictability for the freelancer.
How Many Billable Days Are There Actually in a Year?
This is the input that decides everything else, and it is where most freelancers quietly underprice themselves. Start from 260 weekdays in a calendar year, then subtract in order. Take off the eight bank holidays that England and Wales observe in a normal year — the dates are published on GOV.UK — which leaves 252. Take off the holiday you intend to take: five weeks is 25 days, leaving 227. Take off a realistic allowance for illness, and five days leaves 222. Then take off the days you work but cannot invoice — proposals, invoicing and chasing payment, marketing, bookkeeping, your own training. On most freelance businesses that is one day a week, about 44 days a year, which brings you to roughly 178. Finally, subtract the contract gaps nobody plans for; two or three unbooked weeks a year is normal even for busy contractors, taking a realistic figure to 165–175 billable days. The gap between that and 260 is the whole game: at a £60,000 target, dividing by 260 gives £231 a day, while dividing by 170 gives £353. Quote the first number and you will work a full year and finish roughly £20,000 short of your own target. If you are early in your freelance career and have no history to average, start at 200 in the field above rather than 220–240, then revise it after a year using your actual invoiced days.

Day Rate to Salary: Why Annual Equivalent Is Not the Salary You Are Competing With
Multiplying a day rate by billable days gives gross billings, not a salary you can compare to a job offer. A salaried role also pays for holiday, sick days, employer pension contributions, employer National Insurance, and the training and admin time you now do unpaid. Set Self-Employed Overheads to the share of billings those items consume and the calculator adds two figures: the salary-equivalent of your current rate, and the day rate you would need to match a given salaried package. Worked through: £500 a day over 240 billable days is £120,000 in billings, but at 30% overheads it competes with roughly an £84,000 salary — and matching a genuine £120,000 package would take about £714 a day. That is the same 30-50% uplift experienced contractors quote by instinct, made explicit. Employer NI is 15% on earnings above the £5,000 secondary threshold under the rates published by HMRC, and statutory holiday alone is 12.07% of hours worked, so 25-35% is a realistic starting overhead for most UK contractors before pension and insurance. Set it to 0 if you only want the raw conversion. Updated 2026-08-28.
What Overhead Percentage Should You Use?
Build the number rather than guessing it. Statutory holiday is 12.07% of hours worked for a worker with no contractual holiday, which is the floor for a contractor who takes any leave at all. Employer National Insurance adds 15% above the £5,000 secondary threshold on inside-IR35 and umbrella engagements, where the assignment rate is quoted before that deduction. A pension contribution at the 3% employer auto-enrolment minimum is another 3%, and most contractors target considerably more because nobody else is funding it. Professional indemnity and public liability insurance, accountancy fees, equipment and software typically land between 3% and 8% of billings for a solo consultant. Add those and 25% is a lean outside-IR35 figure, 30-35% is typical, and 40%+ is realistic for an inside-IR35 or umbrella engagement where employer NI and the umbrella margin both come out of the quoted rate before you see anything. Enter your own number rather than a default if you already know your unbilled costs from last year’s accounts. Updated 2026-08-28.
Frequently Asked Questions
Should my inside IR35 day rate be higher than my outside IR35 rate?
Yes — typically by around 20 to 25%. An inside IR35 or umbrella engagement quotes an assignment rate, not your gross pay. Employer National Insurance at 15% above the £5,000 secondary threshold, the 0.5% Apprenticeship Levy, the umbrella margin of roughly £15 to £30 a week, and 12.07% rolled-up holiday pay all come out of that figure before PAYE and employee NI are applied to what is left. Quoting the same number for both engagement types means accepting a real pay cut on the inside IR35 one.
Does a quoted umbrella day rate include holiday pay?
It depends on the agency, and you have to ask. Umbrella workers are entitled to holiday pay at 12.07%, but it is often rolled up into the assignment rate rather than paid on top — so a rate quoted as inclusive is worth 12.07% less than the same number quoted as exclusive. Get it in writing before you accept. From April 2026 responsibility for accounting for PAYE on umbrella workers moves to the recruitment agency or end client, which is expected to remove non-compliant umbrellas from the market.
How do I set a day rate as a contractor?
Setting your day rate starts with understanding your financial needs and market value. Begin by calculating your target annual income, including enough to cover living expenses, taxes, retirement savings, insurance, and a profit buffer. Divide this by your realistic working days per year (typically 220 to 240 days) to get your minimum day rate. Then research market rates for your skill set and experience level in your geographic area. Your final rate should be at or above your minimum while remaining competitive in your market. As a rule of thumb, a contractor day rate should be at least 30% to 50% higher than the daily equivalent of a comparable salaried position to account for the lack of benefits, job security, and paid time off.
Day rate vs hourly rate — which is better for contractors?
Both have advantages, and the best choice depends on the engagement. Day rates offer simplicity and predictability — both you and the client know exactly what a day costs, which makes budgeting and invoicing straightforward. Day rates also prevent the awkward dynamic of clients watching the clock during hourly engagements. Hourly rates offer more flexibility and are fairer when the workload varies significantly from day to day or when you are working part-time for a client. They also protect you when projects run longer than expected. Many contractors offer both options and recommend whichever fits the project best. If you do offer both, set your day rate at a slight discount to 8 times your hourly rate to incentivize full-day bookings.
Should my day rate include expenses?
This depends on the type of expenses and the norms in your industry. Your day rate should generally include the overhead costs of running your business — equipment, software, internet, professional development, and insurance. These are baked into your rate as part of your cost of doing business. However, project-specific expenses like travel, accommodation, specialized materials, or third-party services should typically be billed separately at cost (or cost plus a small handling fee). Always clarify expense handling in your contract before starting work. Some clients prefer an all-inclusive day rate for budget simplicity, while others prefer a lower day rate with expenses billed separately for transparency.
How should I handle half days in my pricing?
Half-day pricing is a common question for contractors. The most common approach is to charge between 60% and 75% of your full day rate for a half day (typically defined as 4 hours or less). Charging more than half makes sense because a half-day engagement still blocks a significant portion of your day and often prevents you from taking on other work. Some contractors define specific thresholds: for example, 1 to 4 hours is a half-day rate, 4 to 8 hours is a full-day rate. Others simply quote their hourly rate for anything less than a full day, with a minimum engagement of 2 or 4 hours. Whatever approach you choose, document it clearly in your terms and communicate it to clients upfront to avoid disputes.
Is a day rate before or after tax?
Day rates quoted by contractors are almost always pre-tax (gross) figures. As an independent contractor, you are responsible for paying your own income tax and self-employment tax from the gross amount you receive. This is an important distinction when comparing contractor day rates to salaried positions. A $500 day rate does not mean you take home $500 — depending on your tax bracket and country, you might retain $325 to $400 after taxes. When setting your day rate, always calculate it based on your post-tax income needs and gross it up to account for taxes. In the US, freelancers and contractors should expect to set aside 25% to 35% of their gross income for federal and state taxes, including self-employment tax.
How many billable days should I use in a day rate calculation?
Use 165 to 175 for an established freelance business, not 260. Starting from 260 weekdays, subtract the eight bank holidays England and Wales observe in a normal year, five weeks of holiday, about five sick days, roughly one day a week of unbillable admin and business development, and two to three weeks of gaps between contracts. If you have no history yet, put 200 in the field above and revise it after a year using your actual invoiced days.
Why is my day rate too low when I divide my target income by 260?
Because 260 counts every weekday as billable and you cannot invoice most of them. At a 60,000 target, dividing by 260 gives 231 a day while dividing by a realistic 170 gives 353. Quote the lower figure and you will work a full year and still finish roughly 20,000 short of the income you were aiming at. Always divide by billable days, not calendar weekdays.
How do I convert a day rate into an equivalent salary?
Multiply the day rate by your billable days to get gross billings, then subtract self-employed overheads — holiday, sick days, pension, employer National Insurance, insurance and unbilled admin. Set the Self-Employed Overheads field above and the calculator shows the salary-equivalent directly. At 500 a day over 240 billable days, 120,000 in billings at 30% overheads competes with roughly an 84,000 salary, and matching a real 120,000 package would need about 714 a day.
What self-employed overhead percentage should I enter?
Build it rather than guess. Statutory holiday alone is 12.07% of hours worked. Employer National Insurance adds 15% above the 5,000 secondary threshold on inside IR35 and umbrella engagements. Employer pension at the 3% auto-enrolment minimum is another 3%, and insurance, accountancy, equipment and software usually add 3 to 8% for a solo consultant. That puts 25% at the lean end for outside IR35, 30 to 35% as typical, and 40% or more for umbrella work where employer NI and the umbrella margin both come out of the quoted rate. Enter 0 if you only want the raw rate conversion.
