How to Calculate Your Day Rate as a Consultant: Arriving at a Rate That Holds Up

A client asks: "What's your day rate?" You take your hourly rate, multiply it by eight and quote the number. Later you realize: the workshop day ran ten hours, travel wasn't included, and the year has far fewer consulting days than you thought. For consultants, coaches and freelancers, the day rate is the most important pricing figure – and often the one set by gut feeling. Here's how to derive it from your own numbers, check it against the market, and which mistakes to avoid.

Why a day rate isn't simply hourly rate times eight

The formula "hourly rate × 8" sounds logical, but it has two catches.

You're selling the day as a whole

With a day rate, the client buys your day, not eight hours. Whether it ends up being seven or nine and a half hours makes no difference to the invoice. That's predictable for both sides, but it shifts the risk to you. That's why you need a clear definition: how many hours does a day cover, is travel time included, and what counts as a half day?

Hourly logic doesn't fit daily logic

An hourly rate is based on the hours you can actually bill – often only five or six per working day, because the rest disappears into preparation, emails and travel. If you multiply that rate by eight, you're pretending all eight hours are billable. Depending on your starting point, the result is too high or too low, but rarely right. The better approach: calculate your day rate directly from your annual costs and your billable days. For how the hourly rate formula works in detail, see How to calculate your hourly rate as a freelancer.

Calculating your day rate in four steps

The basic formula is simple:

Day rate = (operating costs + owner's salary + insurance and retirement provision) ÷ billable days, plus a markup for profit and risk.

Step 1: Gather your annual costs

Collect all the costs your business incurs over the year: office or coworking space, software, hardware, insurance, training, tax advisor, marketing, and travel costs you can't pass on to clients. Work with annual figures – monthly amounts times twelve, one-off purchases spread over their useful life.

Step 2: Set your owner's salary and provision

Your owner's salary is what you'd expect to be paid as an employee for comparable work – before taxes. On top of that comes what an employer would otherwise share: health insurance, retirement savings, cover for longer periods of illness. This block is the one most often forgotten or set too low.

Step 3: Work out your billable days

This is the decisive step. A year has around 260 working days, but you can't invoice anywhere near all of them. You have to subtract vacation, public holidays and sick days – and then the days spent on client acquisition, proposals, admin, training and idle time between projects. What's left are your billable days. You'll find a more detailed derivation in the article Billable hours per year – the logic is the same for days.

Step 4: Distinguish between minimum rate and target rate

Divide the total from steps 1 and 2 by the days from step 3. The result is your minimum day rate: below that, you're working below your own costs. The target rate sits above it – with a markup for profit, investments and the risk that a project falls through or a client pays late. There's no fixed rule for the size of this markup. In the example below we use 15%; that's an assumption you adjust to your own situation.

Worked example: a process consultant's day rate

The following example is fictional and for illustration only. Let's take Lena, a self-employed process consultant who mostly offers her services at day rates.

Two things stand out. First: 128 billable days works out to about two and a half client days per week on average across the year – not many, but realistic once acquisition and preparation are counted honestly. Second: had Lena simply multiplied her gut-feeling hourly rate of €75 by eight, she'd have landed at €600 – a good €100 below her minimum rate. Over 128 days, that's around €13,000 a year missing.

Market rates: comparing your cost-based price with the market price

Your calculation tells you what you need. The market tells you what clients pay. You need to know both.

Where to get market information

Day rate ranges depend heavily on industry, specialization, experience, region, and whether you work on site or remotely. You'll find concrete figures in job postings on project platforms, from agencies and intermediaries, in conversations with peers – and in the budgets clients tell you about when you ask. Collect these figures over a few months and you'll know the range in your niche.

What to do with the comparison

If your minimum rate is above what the market pays in your segment, you have three levers: cut costs, increase utilization, or position yourself so you land in a higher-priced segment. A lower day rate isn't one of them. If the market is well above your target rate, use that headroom. Your minimum rate is a floor, not a price tag.

Half days, remote days, long projects

A small pricing structure makes more sense than a single number. A half day usually costs more than half the day rate, because you can rarely sell the rest of the day elsewhere. On long framework agreements with guaranteed utilization, a slight discount can be fair, because your acquisition effort drops. Agree on travel time and travel expenses in writing beforehand.

Typical day rate mistakes

Counting every working day

Divide €90,000 by 250 days and you get €360, which looks like enough to live on. In reality, that would require 100% utilization – no vacation, no sick days, no acquisition. This is the calculation error with the biggest consequences.

Leaving out owner's salary and provision

If you only cover operating costs, at the end of the year you have a business that sustains itself – but no income. Set your owner's salary realistically, including what you have to pay yourself for health insurance and retirement.

Confusing revenue with income

Your day rate is revenue. Income tax and, depending on your situation, VAT still come off before anything reaches you. Exactly how much depends on your personal circumstances. Plan reserves for that and clarify the details with your tax advisor – THA·ONE is a planning aid, not tax advice within the meaning of the German Tax Advisory Act (StBerG).

Not adjusting your rate for years

Costs rise, experience grows, specialization becomes more valuable. A day rate that was right three years ago often isn't right today. Recalculate once a year – ideally when you're planning your costs for the coming year anyway.

Not defining the day

Does a ten-hour workshop count as one day? Is travel paid? What happens if the client cancels the evening before? Set this out in your proposal and there'll be no arguments later.

From day rate back to hourly rate

Sometimes you need both, for example for small tasks billed by the hour. In that case, don't derive the hourly rate as day rate ÷ 8; calculate it separately based on the hours you can actually bill. It's usually higher than the day rate divided by eight – no contradiction, because a full day is easier for you to plan. For a quick starting figure, the free hourly rate calculator helps. If you want to work with scenarios – more vacation, lower utilization, higher costs – you can play them through in THA·ONE's pricing tool, which derives your minimum price and break-even from costs and utilization.

Conclusion

Your day rate isn't a gut number, and it isn't hourly rate times eight either. It comes from three figures: what your business costs per year, what you yourself need to earn, and the number of days you can genuinely invoice. That gives you your minimum rate. The target rate sits above it, and the market shows you how much headroom you have. Do the calculation properly once, define what a day covers for you, and revisit the number every year. Then the next time someone asks about your day rate, you'll have a well-founded answer.
