Marketing budget as a percentage of revenue in 2027: what the 2026 surveys say, and how to set yours

Marketing budget as a percentage of revenue is total marketing spend, including people, programs and technology, divided by company revenue for the same year. It is the ratio boards and CFOs use first, because it is easy to compare across years and companies.

Three primary sources published in 2026 frame the number for 2027 planning. Each surveyed a different group, so read the second column before comparing your own figure with any of them.

Neither survey reports a B2B-only or SaaS-only figure in its public release, and both mix business models and company sizes. That is why the two headline numbers differ by more than a point, and why neither is a target for your company.

Percent of revenue tells you how a budget compares; it does not tell you whether the budget can hit the plan. Two companies at 8% of revenue can have very different outcomes: one sells $30,000 contracts and needs thousands of opportunities, the other sells $300,000 contracts and needs a few hundred named accounts to move.

It also lags. Revenue is last year’s result, while the 2027 budget has to fund the pipeline for next year’s target. A company planning 30% growth on a flat percentage is quietly assuming that marketing will become far more efficient.

Boards know this. In his list of board-level questions on the marketing budget, Dave Kellogg asks whether the budget was trended from last year or built bottom-up, and pairs marketing as a share of revenue with marketing as a share of new bookings, pipe-to-spend and cost per opportunity. Bring the ratio, but lead with the build.

Build the number from the pipeline the target needs. Jon Miller, CMO of Demandbase, calls this reverse waterfall math: the bookings goal divided by the win rate gives the pipeline required. The rest follows from your own CRM data.

1. Divide the 2027 new-business revenue target by your win rate on qualified opportunities. That is the pipeline you need created or carried into the year.
2. Agree with sales what share of that pipeline marketing sources. Multiply to get the marketing-sourced pipeline target.
3. Divide by average deal size to get the number of qualified opportunities marketing must create.
4. Multiply by your cost per qualified opportunity, by channel if you have it, to get the program budget. Our marketing budget channel planner does this by channel.
5. Add people, agencies and platforms. That total, divided by revenue, is your percent of revenue.
6. Compare it with the survey figures and with 2026. A large gap is a question to answer, not a number to close.

Our marketing budget channel planner runs steps 4 and 5 by channel, the pipeline gap calculator runs steps 1 to 3, and the pipeline coverage math article explains why a fixed 3x rule rarely fits.

This is a worked example with stated assumptions, not a benchmark or a client result. Replace every input with your own figures.

At 5.8% the plan sits below both survey figures. That is not automatically a reason to ask for more. It raises two questions for the plan review: is $4,000 per qualified opportunity a real figure from the CRM, or a hope, and can the team actually create 750 opportunities, about 63 a month, with the channels it has? If either answer is no, the budget or the target has to move.

The board slides for these ratios are covered in how to present your 2027 marketing plan to the board.

• Expect flat, prepare for change. Forrester found 91% of marketers expect increases in 2027, but Gartner’s 2026 data shows budgets almost flat and The CMO Survey measured spending growth of 1.7%. Plan the flat case best and keep minus 10 and plus 10 percent versions ready.
• AI is now a budget line. Gartner measured 15.3% of marketing budgets going to AI, and Forrester advises cutting AI pilots that lack governance, ownership, success criteria or a path to scale.
• Answer engines get a line too. Forrester lists brand visibility in answer engines among the areas B2B marketers should increase in 2027.
• Short-term pressure stays. More than 70% of marketers in The CMO Survey prioritize immediate results, so a plan with no leading indicators in the first two quarters will be judged on closed revenue it cannot yet show.

PlanConversion builds 2027 demand generation plans from the pipeline target down, with the CRM measurement that lets finance trust the cost per opportunity behind them. In our KNIME work, rebuilding paid media measurement, targeting and landing pages cut cost per lead by 51% with lead volume holding steady and made 100% of paid leads traceable to closed deals.
