A day rate is not simply your hourly rate times eight.
A working day rarely contains eight billable hours — meetings, context-switching, and admin eat into it — so a sound day rate is your hourly rate times the hours you can genuinely bill in a day, usually five or six. Set it from your hourly rate, then sanity-check it against the day.
Here's how to build one properly.
Start from your hourly rate
Your day rate should rest on the same foundation as your hourly rate: the income you want to keep, plus taxes, self-funded benefits, expenses, and a cushion, divided by the hours you can actually bill.
If you haven't built that number yet, do it first. Working backward from your target take-home is the only way to land on a rate that actually covers your costs — dividing an old salary by 2,080 will undercharge you badly, because a salaried job was quietly paying for your half of payroll taxes, your health insurance, your retirement match, and a lot of hours you weren't directly producing.
The day rate is just a different way of packaging that same underlying cost.
Multiply by billable hours, not clock hours
The trap is assuming a day is eight billable hours. It almost never is.
Realistically, a focused working day yields five to six hours of billable output once you subtract calls, email, breaks, and the friction of switching tasks. If you set your day rate at hourly × 8, you'll quietly underprice every day you sell — because you're charging for eight hours of value while delivering (and being paid for) the equivalent of six.
Worked example
| Your hourly rate | $104 / hr |
| Genuinely billable hours per day | 6 |
| Day rate (104 × 6) | $624 / day |
| Naive "× 8" day rate (don't use) | $832 / day |
The $624 figure reflects what a real day delivers. You can absolutely round it to a clean $625, or position it higher for specialized work — but anchor it to billable hours, not to the eight-hour clock.
When a day rate beats charging hourly
A day rate works best when the client is buying a block of your time and focus rather than a precisely-scoped deliverable.
It shines for on-site work, intensive workshops, strategy days, or any engagement where you'll be fully dedicated and tracking every minute would be awkward. It also signals seniority — day rates read as more consultative than hourly billing.
Charge hourly instead when the work is sporadic or hard to predict, and use a fixed bid when the deliverable is well-defined.
A few common questions
Should a day rate be discounted versus hourly?
Not automatically. A day rate already reflects realistic billable hours. Some freelancers offer a small discount for booking multiple days, but don't discount reflexively — a full, focused day is valuable.
What if a "day" of work runs long?
Define what a day means up front — e.g., "a day is up to 7 hours of work." That sets a clear boundary and makes it natural to charge for a second day if the scope grows.
How do I quote a multi-day project?
Estimate the number of days, apply your day rate, and add a buffer for the unknowns — the same logic as a fixed bid, just measured in days.
I got tired of doing this math by hand, so I built a free calculator that outputs both your hourly and day rate from the same inputs — Even Keel Rate Calculator. No signup, and every formula is shown so you can check it.
