What this calculator is for
Many clients think in days: on-site workshops, production days, retainers priced by days per month, or “can you give us two days next week?” A day rate packages your hourly economics into a unit that is easier to buy (and easier for you to protect) than open-ended hours.
This calculator starts from your hourly rate, multiplies by billable hours per day, optionally adds overhead per day, then derives a half-day price from your half-day percentage and a weekly package from days per week. Use it once you already know a sustainable hourly floor (or a market rate you are willing to work for).
Why day rates are not “8 × hourly”
A calendar day of focus is not eight clean billable hours. Setup, wrap-up, context switching, and light admin eat the edges. That is why many freelancers price a day around fewer than eight hourly units. The tool’s field note often points at roughly seven times hourly as a common planning pattern, not a universal law. You choose the billable hours per day that match how you actually work.
Half days are also not automatically 50% of a day. A half day still carries ramp-up cost. Setting half-day percentage somewhat above a pure half (when that fits your market) compensates for fragmentation. The calculator lets you model that explicitly instead of negotiating from gut feel on a call.
How to use this calculator
- Hourly rate ($): your billable hourly rate. If you still need a floor, build one with the Hourly Rate Calculator first.
- Billable hours per day: how many hourly units you treat as one day for pricing. Lower numbers raise the day rate for the same hourly input.
- Overhead per day ($): optional add-on for travel, studio, kit, or pass-through costs billed with the day. Use zero when overhead is already inside your hourly rate.
- Half-day percentage (%): what share of the full day rate a half day should be. Common planning discussions sit around half to somewhat above half of the day rate because switching cost remains.
- Days per week: used to show a weekly package total from the day rate (useful for multi-day engagements).
Read the day rate as your default sellable unit, the half-day as a structured smaller buy, and the weekly figure as a package conversation starter, not an automatic discount unless you intend one.
Key ideas for selling days well
Define what a day includes. Hours on site, response expectations, deliverables, and whether meetings outside the day are extra. Ambiguity turns day rates into unlimited access.
Protect focus. Day rates work best when the client buys a block of attention. If the day is shredded into tiny tasks and Slack, your effective output drops even though the fee looks fine. Track reality with the Billable Hours Calculator.
Use overhead deliberately. Travel days, rented space, or specialized gear belong in overhead per day or a separate line item so you do not silently fund client logistics.
Weekly packages need boundaries. Five days on the calculator is a math total. In a proposal, still state start/end times, locations, and what happens if stakeholders cancel mid-week.
A simple example
Take an hourly rate of $100, billable hours per day of 7, no overhead, a half-day percentage of 60%, and 5 days per week. The day rate is 7 × $100 = $700 before overhead. A half day at 60% is $420. A five-day week packages to $3,500 at the full day rate. Change hours per day to 8 and the day rate rises; change half-day percentage to 50% and short bookings get cheaper for the client but less protective for you. The calculator makes those policy choices visible.
When to prefer days vs hours vs projects
Day rates fit workshops, shoots, on-site consulting, and embedded work where presence matters more than a fixed deliverable list.
Hourly fits advisory retainers with variable intensity, but watch meeting creep via the Meeting Cost Calculator.
Project pricing fits clear deliverables. Convert your economics with the Project Pricing Calculator, and keep a change-order path for scope growth with the Scope Creep Calculator.
Many freelancers keep an internal hourly floor, publish day rates for certain offers, and still sell fixed packages where outcomes are clearer than time.
Common mistakes
- Setting hours per day to 8 while delivering 5 hours of focus: you underprice the day.
- Half days at 50% by default without considering switching cost.
- Forgetting travel and kit until you are already on site.
- Allowing “quick questions” outside the bought day until the day rate becomes an open retainer.
Next steps checklist
- Confirm your hourly floor, then enter it here with realistic hours per day.
- Decide a half-day policy and encode it as half-day percentage.
- List overhead items that should appear per day vs inside the rate.
- Write a short “what a day includes” paragraph for proposals.
- After a change in hourly rate or expenses, re-run day and weekly figures before you send the next rate card. The Rate Card Generator can help you present them cleanly.
