What does lead generation cost? And why cost per lead misleads you

Lead generation in Belgium costs roughly 1,500 to 5,000 euros per month with an agency, or a price per lead that varies widely by industry. But the most important lesson of this article: do not fixate on the cost per lead. That number can look beautiful while your revenue stands still. Calculate in cost per customer. In this article you will find realistic prices and how to do the maths properly.

What does lead generation cost in Belgium?

There is no fixed price. What lead generation costs depends on how you approach it, and the cost per lead varies widely by channel, industry and audience. Broadly speaking, you will see three models:

• Agency on retainer: often 1,500 to 5,000 euros per month for an ongoing engagement, depending on scope and channels.
• Price per lead: highly variable, from a few tens to hundreds of euros, depending on how specific and valuable your audience is. The Google Ads benchmarks by industry show how wide that spread is.
• Doing it yourself: no agency cost, but plenty of time and tools, plus a learning curve.

These are guide prices, not quotes. The real question is not what a lead costs, but what a customer costs. To find out whether outsourcing suits you, read outsourced lead generation.

The cost factors that determine your price

The same lead can cost 20 euros at one company and 200 at another. Four factors explain almost all of that difference.

Channel

Every channel has its own cost structure. Search traffic via SEO or GEO costs time and content up front, but gets cheaper per lead as it scales. Paid channels such as Google Ads and LinkedIn carry a direct click or impression cost that you keep paying for every lead. In practice we see companies pick one channel on gut feel, while the right mix depends on your sales cycle and margin.

Industry

In an industry with fierce competition and expensive customers, think legal, financial or B2B software, you pay considerably more per lead than in a niche market with little bidding war. The cost per lead follows the value of the customer: the more a customer is worth, the more everyone is willing to bid to reach them.

Quality versus volume

You can steer on many cheap leads or on few but sharper leads. Targeting broadly lowers the cost per lead, but fills your pipeline with people who will never buy. Targeting sharply raises the price per lead, but often delivers a lower cost per customer. The cheapest option on paper is rarely the cheapest in reality. More on this in qualified leads.

In-house versus agency

Doing it yourself saves the agency cost, but costs time, tools and a learning curve in which you burn budget while you learn. An agency or specialist charges a margin, but brings experience and speed. Which one turns out cheaper depends on your internal capacity and how quickly you need results. We compare the options in in-house vs outsourced lead generation.

Cost per lead by channel

The table below gives an indicative direction per channel. Treat the amounts as rough orders of magnitude, not as quotes: your own industry, targeting and offer can easily halve or double them.

SEO and GEO

Search engine and AI visibility require an upfront investment in content and technology, but the cost per lead drops as pages rank and attract traffic without a media cost per click. It is the patient channel: count on months before it pays off. Start with SEO for lead generation.

Google Ads

Paid search delivers leads quickly, but you pay per click and that cost swings heavily by industry. The biggest waste sits in poorly targeted campaigns that produce clicks without enquiries. See realistic figures in cost per lead via Google Ads.

LinkedIn

LinkedIn is usually the most expensive channel per lead, but it lets you target precisely on job title, company and industry. For B2B with a high customer value, that precision often outweighs the price. More in LinkedIn lead generation.

Cold outreach

Cold email has a low direct media cost, but stands or falls with the quality of your list, your message and your follow-up. It is a volume game that takes a lot of time. See cold email in Belgium.

Why cost per lead misleads you

Cost per lead, the price per lead brought in, is the most dangerous number in lead generation. It looks good on a dashboard, but it hides whether those leads actually become customers.

Imagine: agency A delivers leads at 30 euros each, agency B at 90 euros. A seems three times cheaper. But if none of A’s leads buy and one in five of B’s leads do, then B is dirt cheap and A is wildly expensive. The low cost per lead was an illusion.

A low cost per lead that gets nobody to buy is more expensive than a high cost per lead that delivers customers. Calculate in customers, not in leads.

The example in one picture: on paper the cheap lead looks like the better choice, until you count how many of them actually become customers.

Steer on cost per qualified lead

The way out of the cost-per-lead trap is one concept: cost per qualified lead. Not what every incoming lead costs, but what a lead costs that fits your ideal customer and has a real chance of buying. Translate that into the numbers that do count:

• Cost per customer. What does it cost you to win one customer through lead generation?
• Lead-to-customer conversion. How many of your leads eventually buy?
• Customer value. What does a customer earn you across the whole relationship?

This is how you steer in practice: filter your leads on fit before you calculate the cost, tie closed deals back to the channel that brought them in, and shift budget to the channel with the lowest cost per customer, not the lowest cost per lead. We steer on leads that become customers, not on volume in a dashboard.

Only once you know these do you know whether lead generation pays off. An expensive lead that often turns into a valuable customer is gold. A cheap lead that never buys is money down the drain. That is exactly what we saw in an account-based marketing engagement that delivered 189% more MQLs at 22% lower monthly costs: fewer but sharper leads, a lower cost per customer. It ties in with lead quality.

Beware of cheap leads

Cheap almost always turns out expensive in lead generation. Low prices and no cure no pay models deliver volume, not customers. See why in pay per lead and no cure no pay.

And do not forget the other side: leads are only worth something if your site converts them. The cheapest win often sits in a better conversion rate via conversion optimization, not in more or cheaper leads.

Common mistakes

• Steering only on cost per lead. The classic: picking the cheapest channel and only noticing months later that not a single lead became a customer.
• Choosing channels detached from your margin. An expensive lead is no problem with a customer worth tens of thousands of euros, and a cheap lead is too expensive on a margin of a few tenners.
• No feedback loop from deals back to channel. Without knowing which channel brings in paying customers, you optimize blindly on the wrong number.
• Forgetting your site’s conversion rate. You buy in leads while the cheapest win often sits in a better conversion rate.
• Seeing no cure no pay as free money. You still pay, only in leads that rarely fit. See pay per lead and no cure no pay.

From costs to returns

The price of lead generation is not a goal in itself. The goal is return: more customers at a healthy cost per customer.

In the engagements we roll out, we often see a doubling to tripling of the number of enquiries. Our approach for Get Driven delivered 400% more conversion, and that is where the real saving sits.

Frequently asked questions

What does a lead cost on average?

There is no reliable average: the cost per lead runs from a few tens to hundreds of euros, depending on channel, industry and how sharp your targeting is. An average across all industries says little about your situation. Better to calculate with your own conversion rate and customer value than with a benchmark.

Is outsourcing lead generation cheaper than doing it yourself?

That depends on your internal time and experience. Doing it yourself saves the agency margin, but costs time and a learning curve in which you burn budget. An agency is more expensive per month, but often faster towards a return. Weigh it against your margin and urgency in in-house vs outsourced lead generation.

Why is the cheapest lead not the best choice?

Because price and value are not the same thing. A 30 euro lead that never buys is more expensive than a 90 euro lead that does become a customer. What counts is the cost per customer, not the cost per lead.
