A day rate is not eight hours of your hourly rate. It is a discount for a client who buys your whole day, and the difference decides whether short days make money or lose it.
Most trades and freelancers pick one model by habit. The ones who earn well use both, and know exactly which jobs should be priced each way. This is the arithmetic behind the choice, and the wording that stops clients arguing about it.
The arithmetic nobody does
If your hourly rate is 45 and you charge 360 for a day, you have not charged eight hours. You have charged eight hours minus the two hours you would have lost to travel, gaps and admin between five separate jobs. The day rate looks like a 20% discount and is really about even, provided you fill the day.
Work it from your costs instead. Take the annual figure you need to cover overhead plus your own pay, divide by the number of full working days you actually sell in a year, and you have a floor. The overhead calculator produces the annual number; the rate calculator converts it to a rate. A day rate below that floor is a busy fool’s price.
Who each model suits
Hourly suits diagnostic, unpredictable work: call-outs, repairs where you cannot know the scope until you are there. It protects you when the job turns out to be two hours instead of twenty minutes.
Day rate suits blocks of committed, predictable work where the client controls the diary: site work, installs, retained maintenance days, agency-style support. It also suits work where the client would otherwise micro-manage the clock.
Fixed price suits scoped jobs with clear boundaries, which is why quoting electrical work is its own skill: the price covers the risk you have identified, not the risk you are guessing at.
The day rate has to come with a definition
Half the disputes about day rates come from an undefined day. Write down the hours, the start time, whether travel counts, and what happens when the client is not ready when you arrive. A day where you stand around waiting for access is still a day consumed.
Write a short "what a day rate includes" section for my website, using the details below. DETAILS - Trade or service: [what I do] - Day rate: [amount] - Standard day: [hours] from [start time] - Travel: [included within X miles / charged separately] - Overtime: [rate per hour after the standard day] - Materials: [separate / included up to X] - Waiting time and access: [how I treat it] - Cancellation: [notice period] Rules: plain sentences, no legal jargon, under 180 words. Use "you" for the client. End with one line telling them what to do if they are unsure whether they need a day or a half day.
Half days, overtime and the awkward bits
Half days are where day rates quietly lose money. A four-hour booking at half the day rate has none of the flexibility of a full day and often the same travel. Price half days above half, usually 60 to 65% of the day rate, and say so before someone asks.
Overtime needs a trigger and a rate. Eight hours is a convention, not a law; pick a standard day that matches your trade, write the overtime rate beside it, and charge from the first hour over rather than the second.
Convert my hourly and day figures into a clean rate card I can send to clients. INPUTS - Hourly rate: [amount] - Day rate: [amount] - Half day: [amount, or ask me to suggest one at 60-65% of the day rate] - Overtime after [hours]: [amount per hour] - Minimum call-out: [amount, covering X minutes] - Materials and travel policy: [brief] Produce a one-page rate card with a header, five priced lines, and three one-sentence policies (materials, travel, cancellation). No fluff, no marketing language.
What clients assume, and how to correct it
Clients hear “day rate” and assume availability: your whole day, theirs to direct. You hear “day rate” and mean eight working hours on their job. Say which you mean before the day starts, because retrofitting the distinction mid-job reads as sharp practice even when it is fair.
If a client needs certainty about finishes rather than hours, sell them a fixed price and carry the risk explicitly. That is what the job profit calculator is for: it shows what a fixed price leaves you after real costs, so the risk you are taking has a number attached.
When the day rate is the wrong tool
Short jobs. A two-hour job priced at a day rate is a discount you did not intend. Travel-heavy days where most of the day is driving. Work where the client will cancel at short notice, unless you have a cancellation term you actually enforce.
And any job where you cannot predict the scope. Day rates reward predictable work; where the work is unknown, hourly protects you and fixed price charges for the unknown. Mixing them badly is how businesses end up busy and broke, which is the argument in charging for extra work.
Explaining the day rate to a client comparing hourly
The question every client asks: “why is a day 360 when your hourly is 45?” The answer is not a discount explanation, it is a scope one: the day buys availability, not eight billed hours.
Write a short explanation for a client who has compared my day rate with my hourly rate. DETAILS - Hourly rate: [amount] - Day rate: [amount] - Standard day: [hours] from [start time] - What the day includes that hourly does not: [travel, continuity, set-up, priority scheduling] - What still costs extra: [materials, overtime, weekend, travel beyond X miles] Rules: three short paragraphs. First line answers the arithmetic directly. Second explains what they get for the difference. Third tells them which model suits their job. Under 160 words, no defensiveness, no jargon.
Frequently asked questions
Is a day rate always cheaper than hourly for the client?
Usually, yes, and that is the point: they are buying commitment. If it is not cheaper, there is no reason for them to accept the loss of flexibility.
Should I charge the same day rate for every client?
Same base rate, different terms. Weekend, out-of-hours and short-notice work carries a premium; that is a term, not a different rate.
How many days can I actually sell in a year?
Far fewer than 260. Allow for holidays, sickness, quoting, admin and the days you are on site but not billing. Most small firms sell 160 to 200 full days.
What if the client wants a breakdown of the day rate?
Give them the rate card, not your cost structure. They are buying an outcome and a price, and your overhead is not their business.
