B2B Content Marketing Budget: How to Plan It Without a Benchmark

Ask ten marketers what a B2B content programme should cost and you get ten percentages, nearly all with no sample behind them. A finance lead who asks where a figure came from tends to discover a vendor's customer list, or a blog post quoting another blog post.

This guide offers another route: a budget memo built from your own spending, your buyers' habits and your team's real capacity. It takes an afternoon, needs a spreadsheet and a rough idea of last year's costs, and produces a document that holds up when the questions start.

Context first: how big is the whole marketing pot?

Content is a slice of a larger marketing budget, so it helps to know the size of the pot. The usual reference is the CMO Survey run by Duke University, Deloitte and the AMA. A secondary write-up of its spring 2026 results reports marketing spend of 7.0% of revenue for B2B product firms and 10.1% for B2B services firms. The write-up does not state a sample size or define "marketing spend", and it is not the survey itself, so read the numbers as background only.

What no source we found tells you is how much of that pot content should take. That gap is the reason for building from the bottom up.

The memo, in four parts

Part one: where the money goes now

Take twelve months of actuals and group them under five headings: staff and freelancers, software, distribution such as promotion and events, specialist time for interviews and review, and measurement. Value internal hours at a loaded rate. Specialist time is the heading most often left blank.

Usually one or two headings swallow the bulk of the money. Software is typically the smallest heading and the simplest to cut, so it gets trimmed first even though it is rarely the real problem. Where you are guessing, give a range and say so.

Part two: which stage of the buying journey each pound buys

The 6sense 2025 buyer experience report found that the vendor that won had been on the buyer's day-one shortlist 95% of the time. If lists form before contact, content that gets you named early merits a visible share. Mark every activity early (awareness and shortlisting), middle (evaluation) or late (decision), then add up each group.

A budget weighted towards late content serves people who have already decided. One weighted towards early content needs a check that sales can close what it attracts. No ideal ratio exists, but a defensible one does.

Part three: capacity you can actually review

Calculate how many pieces the team can ship while still getting expert review and a refresh cycle, and budget for that number only. Anything past it leaves behind out-of-date pages, shaky claims and an uneven voice. Google warns that mass-producing pages with no added value for users may breach its spam policy, and a smaller programme kept current usually outlasts a larger one left alone. Hold back a fixed fraction of capacity for updating old pages, and secure specialist hours before agreeing any volume.

Part four: what you will show in a year

Choose three measures today: reach, engagement or quality, and a business result such as pipeline that content touched. Write the attribution caveats beside them. Metrics by funnel stage says what each stage can prove. Review every quarter and move money from the weakest activity towards the strongest.

Where AI belongs in the sums

The 2025 CMI and MarketingProfs survey of 1,015 marketers found that 45% ranked AI-powered tools among their top three areas for added 2026 investment, while spending on people, meaning salaries, training and development, came last at 9%. Within the same survey, AI users reported improved productivity far more often than improved content performance: 87% against 39%. Speed is easy to find, and proof of results is thin.

Our reading, offered as opinion, is that shifting budget into tools while cutting training for the people who steer them amounts to a bet that tools succeed alone. Think of AI as a multiplier on drafting and structure, and cost it per task. Cost per published article shows how, and platform pricing explains vendor charges. Record the hours a piece takes before and after a tool arrives, and test promised savings across a full quarter.

Fund specialist hours as a line of their own

The usual budget pays for writers and software and treats specialist hours as free. They are neither free nor abundant; they are the scarcest input in the system, and an unfunded input is the first thing dropped when a deadline tightens. What survives is fluent, generic copy, which is exactly what AI drafting makes cheap and what readers and assistants have least reason to cite.

We would give those hours a named line, even if the figure is an internal estimate, and protect it first when cuts arrive. The price is real calendar time from people with other jobs, and some will push back. A business whose edge is repackaging public information needs the opposite approach, because editorial craft matters more there than access to a specialist. Where the purchase is complex, a modest budget that secures a few real specialist conversations each month outperforms a bigger one that simply buys more drafts.

A walk-through on made-up figures

Every figure here is invented, to display the logic. Over a year a team spends 100 units, split 62 staff, 8 software, 18 distribution, 4 specialist time and 8 measurement. By stage, 15 units go to early content, 30 to the middle and 55 to late pages and sales support.

Two decisions result. Specialist hours are tiny yet affect every piece, so lifting them from 4 to 8 is cheaper than another writer and likely improves quality. Since the buyer data says lists form early, the team also moves 10 units out of late production into explainers and comparisons, with a review in a quarter. This is no template for your split. What carries over is the order of work: measure your ratio, test it against how buyers decide, then change one thing at a time.

Three starting positions and what each should do first

You have no budget line at all. Content is paid from scattered team budgets and nobody can say the total. Do part one before anything else. The act of adding up hours and invoices usually produces the argument for a proper line, because the real total is larger than anyone guessed.

You have a budget and no evidence. Money is spent, but nothing links it to buyers. Do parts two and four: tag spend by stage and agree the three measures. Resist adding new activity until you can show what the current activity does.

You are being asked to cut. Protect specialist hours and refresh capacity, since they keep existing assets accurate, and look first at volume that exceeds your review ability. Cuts to the lowest-reviewed output often improve average quality, which is an argument that lands well with finance.

Three questions finance will ask

One: what happens if we spend nothing for a quarter? Name the pages that would decay and the channels that would go quiet. Two: what is the payback? Effects are slow and shared with other channels, so give a range plus leading indicators. Three: why not simply buy ads? Ads end when spending does, whereas pages keep working while they stay accurate, provided someone maintains them.

How to treat published benchmarks

You will meet precise ranges for newer disciplines. Profound's guide gives $75k to $150k a year for mid-market GEO programmes and $250k or more for enterprises, and says the numbers are based on its own customer base, not independent research. We cannot verify them, so they play no part in setting your number. Use such figures only to test whether your plan is wildly out of range.
