Day Rate Calculator: What to Charge Per Day
A day rate is the cleanest way to price contract work, because it stops the clock-watching and prices a unit the client understands. It is also easy to set too low, since a day rate hides the unbillable days an hourly rate at least makes visible.
To take home $85,000 while billing three days a week for 44 weeks with $9,000 of overhead, the day rate is $906.
How it's calculated
A day rate is your hourly rate multiplied by the hours in your working day, but working it out that way misses the point. Start where every rate calculation should start: with the take-home you want, and the days you can genuinely sell.
The days you can sell are fewer than the days you work. A contractor billing three days a week is at 60% utilization on a five-day week — the other two days go to pitching, admin, invoicing, and the work that keeps the pipeline full. Then subtract the weeks you will not work: holidays, illness, and the gaps between contracts. Forty-four working weeks is realistic for a contractor whose engagements do not run back to back.
So: 3 days a week for 44 weeks is 132 billable days. To take home $85,000 after $9,000 of overhead, and after federal self-employment and income tax on the profit, you need $119,594 of revenue. Divided across 132 days, that is $906 a day, or $113.25 an hour on an eight-hour day.
Day rates carry two specific risks that hourly billing does not, and both are worth pricing in explicitly.
The first is scope. A day is a unit of time, not a unit of work, so a client who asks for "one more small thing" at 5pm is asking for part of tomorrow. Define what a day means — hours, availability, whether it includes calls — in the contract rather than discovering the definition mid-engagement.
The second is the half day. Clients frequently want them, and a half day rarely costs you half a day: the context switching means the remaining hours are worth less than a clean block. Either price half days above half the rate, or decline them and offer a full day instead.
One structural advantage is worth using. A day rate makes multi-day and retainer bookings easy to quote, and a retainer of a fixed number of days a month converts your worst problem — irregular income — into something closer to a salary. It is also the natural place to offer a discount you can defend: a small reduction for a committed block of days costs you less than the pitching time it saves.
As with any rate calculation, the number this produces is a floor rather than a price. It tells you where the work starts costing you money. What a client will pay depends on the value of the outcome, and for well-defined deliverables a fixed project fee often pays better than either day rate or hourly.
Day Rate vs. Hourly Rate
The two billing models handle unbillable time and scope changes differently. An hourly rate keeps every billable fraction visible and prices scope changes automatically, much like logging time through a billable hours calculator. A day rate keeps context-switching and brief admin tasks hidden inside one predictable daily fee.
Agreements require clear boundaries under a daily model. Because a day measures time instead of a finished deliverable, your contract must define daily hours and revision limits upfront. In the worked example above, that day rate comes to $906, which equals $113.25 an hour on an eight-hour day.
Default to a day rate for predictable contract work where the client values a set budget. Switch to an hourly rate when scope is genuinely unpredictable and weekly hours fluctuate. For a well-defined deliverable with clear boundaries, a fixed project fee beats both options by separating your revenue from hours worked.
A worked example
A contractor bills three days a week — 60% utilization against a five-day week — for 44 weeks a year, which is 132 billable days. They want $85,000 of take-home and carry $9,000 of overhead in insurance, software, accounting, and equipment.
Covering the take-home, the overhead, and the federal self-employment and income tax on the resulting profit requires $119,594 of revenue. Across 132 days that is $906.02 a day, or $113.25 an hour on an eight-hour day.
Pricing the same target across an imagined 260 billable days would have produced a day rate near $460 — barely half of what the work actually needs to earn.
Common mistakes to avoid
- Dividing an annual salary by 260 working days. That assumes every working day is billable and that you are paid for holidays — neither is true for a contractor.
- Forgetting the gaps between contracts. A contractor working 44 weeks a year is common; pricing as though it were 52 makes every unbooked week an unfunded pay cut.
- Leaving a day undefined in the contract. A day is a unit of time, not of work, so state the hours it covers and whether calls and revisions are included.
- Charging exactly half for a half day. Context switching means the rest of that day is worth less than a clean block, so half days should carry a premium or be declined.
- Treating the calculated rate as your price rather than your floor. It is the point below which the work loses money, not a measure of what the outcome is worth.
Frequently asked questions
How do I calculate a freelance day rate?
Work backwards from take-home. Add the take-home you want, your business overhead, and the federal self-employment and income tax on that profit, then divide by the days you can genuinely bill — days per week times the weeks you will actually work. Three days a week for 44 weeks is 132 billable days, and $85,000 of take-home with $9,000 of overhead needs $119,594 of revenue, which is $906 a day.
How many billable days a year should I plan for?
Between 130 and 190 for most contractors, depending on utilization. Three billable days a week across 44 working weeks is 132; four days across 46 weeks is 184. The two things that pull the number down are unbillable time — pitching, admin, invoicing — and the gaps between engagements. Assuming 260 billable days prices your work at roughly half what it needs to earn.
Should I charge half of my day rate for a half day?
Usually more than half. A half day fragments the rest of the day: the context switching means the remaining hours rarely produce a full half day of useful work elsewhere. Many contractors price a half day at 60% to 70% of the full rate, and some decline them entirely and offer a full day instead. What does not work is pricing them at exactly half and absorbing the lost productivity.
Is a day rate better than an hourly rate?
For contract work with a predictable shape, generally yes — it is easier to quote, easier for a client to budget, and it removes the incentive to watch the clock. Hourly is better where the scope is genuinely unpredictable, because it prices changes automatically. For well-defined deliverables, a fixed project fee often beats both, since it decouples your income from the hours and rewards you for getting faster.
Should I discount for a long booking?
A small discount for a committed block of days is usually defensible, because it removes pitching time and idle gaps you would otherwise carry. Keep it modest — a booked month is worth more than an unbooked one, but not so much more that it justifies a steep cut. The comparison to make is against your realistic utilization: if the alternative to a discounted month is two billed weeks and two idle ones, the discount pays for itself.
