How much should you be spending on B2B marketing?

It’s one of the most common questions B2B leaders ask us. And one of the hardest to answer in one go.

How much should you be spending on marketing?

Is your budget too small, too big, or about right?

The frustrating truth is that there is no single correct number. But there are clear ways to tell whether your current level of investment is realistic, sustainable and aligned with what the business expects marketing to deliver.

Why percentages of revenue are a poor starting point

Most conversations about marketing budget begin with benchmarks. You will often hear figures like five to ten percent of revenue for marketing spend, sometimes higher for fast-growing businesses.

Benchmarks can be a useful sense check, but they are a weak foundation for decision-making. They strip out context and assume that businesses with similar revenue face similar challenges, ambitions and buying dynamics.

Two B2B companies with identical turnover might need very different marketing budgets depending on their growth goals, market maturity, sales model and level of differentiation. Starting with a percentage often leads to underinvestment or misallocation, rather than clarity.

What marketing is responsible for shapes the budget

Before you talk about numbers, it’s worth answering a more important question.

What is marketing actually expected to do?

In some organisations, marketing exists primarily to support sales with campaigns and materials. In others, it is expected to drive lead generation, open new markets, reposition the business or reduce reliance on outbound activity.

The broader the remit, the greater the investment required. A modest budget can typically sustain visibility. It rarely supports sustained growth, differentiation and pipeline impact at the same time.

This is why marketing spend needs to be viewed as an investment rather than a cost. Brand, credibility and trust all influence commercial outcomes, even if they don’t always appear in a single dashboard.

The four areas that shape most B2B marketing budgets

At Articulate, we see B2B marketing spend as four capability areas. Together, they form the foundations of effective, scalable marketing.

Brand strategy

Brand strategy shapes how your business is understood in the market. It influences positioning, messaging, differentiation and long-term trust.

Investment here tends to be front-loaded, but its impact is long-lasting. A clear brand strategy reduces friction across every other marketing activity, from content creation to sales conversations. Without it, teams often spend more time compensating for ambiguity than building momentum.

Brand work rarely delivers instant results, but it underpins almost everything that follows.

Website building and optimisation

For most B2B organisations, the website is the most important commercial asset they own. It is where buyers form opinions, test credibility and decide whether to engage further.

There is a significant difference between a basic site refresh and a performance-led website designed around real buyer needs. Ongoing optimisation, content evolution and user experience (UX) improvements matter just as much as the initial build.

When businesses underinvest in their website, every other marketing effort works harder for less return.

Copywriting and content

Content plays a central role in building trust and visibility, but quality varies widely.

Expert copywriting costs more than generic output because it involves research, audience understanding and strategic thinking, not just writing words. Copywriting agency rates and retainers can vary significantly depending on scope and expertise, but the underlying trade-off is consistency and quality in your messaging.

Low-quality content often looks efficient on paper and expensive in practice. It underperforms, fails to differentiate and needs constant replacement. High-quality content compounds in value over time, in terms of things like search rankings and brand recognition.

HubSpot implementation and optimisation

Marketing platforms like HubSpot are rarely just a licence cost.

Effective use typically includes onboarding, integration, data modelling, ongoing optimisation and operational support. Underinvestment here tends to show up later as poor reporting, inefficient workflows and misalignment between marketing and sales. Underutilisation can also be a factor, with businesses paying for features they don’t use. To learn more about this, watch our webinar on optimising your HubSpot pricing.

A well-implemented platform creates opportunities for efficiency gains and scale across campaigns, content, and data insights. A poorly implemented one becomes an expensive database.

Growth ambition changes the maths

One of the clearest drivers of marketing spend is growth ambition.

If your goal is to maintain position and support an established sales motion, your required investment will be lower. If your goal is to grow quickly, enter new markets or reposition the business, marketing becomes a growth engine rather than a support function.

That shift requires stronger foundations across brand, website, content and systems. Trying to deliver aggressive growth targets with a maintenance-level budget creates tension that eventually shows up as missed targets or team burnout.

The hidden cost of underinvestment

One reason budget conversations are difficult is that the cost of underinvestment is rarely visible.

You see the spend on projects and platforms. You don’t always see the opportunity cost of weak positioning, slow progress or lost deals.

Underfunded marketing often shows up as inconsistent messaging, fragile pipelines and teams spending more time fixing problems than learning and improving. None of this feels dramatic in isolation, but over time it can compound into terminal problems.

To counter this, leaders need to make the invisible visible. That means quantifying the impact of underinvestment by modelling pipeline shortfalls against revenue targets, tracking win rates alongside brand and positioning strength, and calculating the cost of delayed market entry or missed segments.

Building a credible business case for marketing is not about defending spend. It is about demonstrating how the right level of investment protects growth, reduces risk and creates measurable commercial advantage over time.

“The positive thinker sees the invisible, feels the intangible and achieves the impossible.” Winston Churchill

A better way to sanity-check your marketing budget

Instead of asking how much other companies spend, work backwards from what you need marketing to achieve.

• What level of pipeline contribution is expected?
• How competitive is your market?
• How long is the sales cycle?
• How differentiated is your proposition today?
• Which of the four above foundations are weakest right now?

These questions help you design a budget that supports outcomes rather than activity. At that point, the number becomes a consequence of strategy, not a guess.

Budget is an intentional decision

There is no universal answer to how much you should be spending on B2B marketing.

But there is a clear pattern. When expectations rise while investment stays flat, something eventually breaks. Either results stall, or teams burn out trying to compensate.

Effective marketing budgets are intentional, sustained and aligned with ambition. They recognise that growth, credibility and trust require investment, and that the return compounds over time.

If you want marketing to deliver more, it needs to be funded like the growth function it is, and we can help you get the most of your spend. Get in touch to find out more.
