Calculate Sales Costs: Formula, Calculator & Benchmarks

Most companies systematically underestimate their sales costs. They see salaries, CRM licenses, a few travel expense reports – and think that's it. What they fail to account for: social security contributions, onboarding, management time, tool stacks, and the three-month ramp-up period during which a new salesperson doesn't close a single deal.

If you don't know your sales costs, you can neither manage nor reduce them. And if you don't know what a new customer truly costs you, you also don't know if your sales operations are profitable.

This guide shows you how to calculate your true sales costs, what the relevant benchmarks are, and where the biggest levers lie.

‍

What are sales costs?

Sales costs are all expenses incurred in selling your products or services. They are directly tied to your sales activities and are incurred regardless of whether a deal is actually closed in the end.

In English, they are called "Selling Expenses" or "Distribution Costs" – and this is precisely where many companies have their first misunderstanding: Sales costs aren't limited to field sales. They arise wherever time and money are spent to turn prospects into customers.

‍

Sales Costs vs. Marketing Costs – Where's the Line?

Marketing costs are incurred to build awareness and generate interest.

Sales costs are incurred to drive specific sales closures. Specifically, this means: A Google Ads campaign that generates leads is marketing. The follow-up conversation a salesperson has with that lead is sales.

‍

Sales Overhead vs. Direct Sales Costs

Sales Overhead Costs cannot be directly attributed to a single product and are allocated proportionally, such as salaries, trade shows, CRM licenses, and training.

Direct Sales Costs are directly attributable to a specific order. Commissions, packaging costs, customs duties, specific shipping costs.

‍

What costs are truly involved?

The obvious cost categories

Personnel costs are the largest item. This includes not only the gross salary, but also the employer's social security contributions – approximately 20% of the gross salary. A salesperson with an annual salary of €50,000 thus already costs the employer around €60,000 without bonuses.

Travel and field expenses quickly add up to several thousand euros per salesperson per year.

‍Tool licenses for CRM, email automation, prospecting tools, and LinkedIn Sales Navigator cost €500–€2,000 per salesperson per month.

‍Trade show and event costs often account for 5–15% of the annual sales budget.

‍

The hidden costs – what most people forget

According to Salesforce State of Sales Report B2B salespeople spend on average only about 28% of their working time on actual customer conversations. The rest is spent on CRM maintenance, internal meetings, and manual research. This time costs money but doesn't generate sales.

Added to this are

‍Recruiting and onboarding (3–6 months of ramp-up time without full productivity),

‍Management time (significant portion of the sales manager's time for coaching and administration) and

‍poor lead quality (time spent with prospects who will never buy).

Calculate Sales Costs – Formula and Step-by-Step

The Sales Cost Ratio

A company with €2,000,000 in net revenue and €300,000 in sales costs would have a sales cost ratio of 15%.

‍

Deriving CAC from Sales Costs

If you spend €75,000 on sales in a quarter and acquire 15 new customers, your CAC is €5,000. As a guideline: A CLV:CAC ratio of at least 3:1 is considered healthy.

‍

Example Calculation: B2B Company with Three Sales Employees

With €2,000,000 annual revenue: Sales cost rate 16.5%. With 40 new customers: CAC €8,250. Without recruiting and management time, it would only be €293,000 – a difference of €40,000, which is often overlooked in many plans.

‍

What is a Good Sales Cost Percentage? Benchmarks by Industry

According to Gartner benchmarks B2B companies average 10–15% of revenue for sales costs.

In my opinion, the absolute percentage is less important than its development over time. If your sales cost rate increases even though revenue is growing, that's a warning sign. If it decreases with consistent revenue, efficiency is moving in the right direction.

Especially for B2B cold outreach it shows that those who automate research and still send personalized messages end up significantly below the costs of traditional field sales models. Tools like LeadScraper generate target-group-specific lead lists in real-time, without a salesperson investing hours in manual research.

Reduce Sales Costs – 5 Ways That Really Work

1. Implement a hybrid sales model

According to McKinsey data hybrid sales models reduce travel costs by 30–40% without decreasing closing rates. Video calls for initial discussions, in-person meetings only for deals where presence truly makes a difference.

‍

2. Increase lead quality instead of calling more leads

Specifically, this means: a sharper ICP, clear target audience definition, and qualification before the first sales call. Giving your sales team only leads that are a true fit lowers CAC without a single extra euro spent. How to do this is explained in the Guide to B2B Lead Generation.

‍

3. Implement automation in lead research

If a salesperson spends two hours daily Googling company contacts, with an annual salary of €50,000, that costs around €12,500 per year – just for research. Lead enrichment tools automate exactly this part with a higher hit rate.

‍

4. Consolidate your tool stack

Review annually: Which tools are actively used? Where are there overlaps? What can be automated through integrations without purchasing additional licenses?

‍

5. Improve conversion rate instead of increasing volume

Sending 10% more leads into the funnel also increases sales costs. Improving the closing rate by 10% lowers CAC without additional expenses. Better demo structures, targeted objection handling, faster follow-up.

‍

Conclusion

Correctly calculating sales costs is fundamental to knowing if your sales are truly profitable. Your sales cost ratio should be between 5 and 25%, depending on the industry. CAC is a more relevant metric than absolute costs. And hidden costs exist almost everywhere, especially due to in-house contributions and recruiting, which are often missing from standard calculations.

If you want to reduce your sales costs, the two most effective ways are more precise lead quality and greater automation in research. Both can be achieved with a clearly defined ICP and the right tools, without expanding your team.
