Marketing Budget Benchmarks 2026: How Much Should Growth Cost?

What percentage of revenue should marketing spend in 2026?

The broadest current reference is Gartner's 2026 CMO Spend Survey. It reports marketing budgets at 7.8% of company revenue, up slightly from 7.7% in 2025. The survey covered 401 CMOs and marketing leaders in North America, the United Kingdom and Europe, and the vast majority represented companies with more than $1 billion in annual revenue. That scope matters: scale, category maturity, existing brand demand and centralized capabilities can make a large-company average inappropriate for a smaller growth business.

A more segmented B2B reference comes from Benchmarkit's 2025 study, fielded among 323 companies in November and December 2024. Its median marketing-budget share falls as company size increases, although the $50-100 million band is slightly higher than the preceding band. The same report shows medians of 7% of revenue for companies growing below 10%, 8% for 11-20% growth, and 10% for both 21-30% and above-30% growth cohorts. These are descriptive medians, not proof that the budget caused the growth.

B2B marketing budget medians by company size

The table below reproduces the company-size medians published in Benchmarkit's summary table. It is useful because it avoids applying one blended number to every B2B business. A smaller company often needs a higher revenue share because it has less inherited demand and fewer shared capabilities. A larger company may benefit from brand, installed customer base, procurement leverage and reusable infrastructure. The percentage can still vary materially by category and growth ambition inside each band.

Technology percentages in the source are generally 10%, with 14% in the $100-250 million band. The people, program and technology figures should not be forced to sum to 100% because the source table presents selected allocation categories and survey medians independently. Preserve the source definitions instead of inventing a balancing category.

Define the all-in marketing budget before comparing percentages

A percentage is comparable only when its numerator is comparable. Define all-in marketing investment as internal marketing people, agencies and freelancers, paid media, content and creative production, events, website and conversion work, MarTech, analytics, data and research. Keep sales compensation and sales technology separate unless the benchmark explicitly combines sales and marketing. Record one-off transformation cost separately so the recurring operating budget remains visible.

Calculate the budget backwards from the growth target

Begin with the incremental revenue target. Divide it by average new-customer revenue to estimate required wins. Divide wins by the historical opportunity-to-win rate to estimate required qualified opportunities, then work backwards through sales-accepted lead and inquiry conversion. Apply channel-specific cost ranges only after the required volume and quality are visible. This exposes whether the plan is limited by budget, conversion, sales capacity or the addressable market.

Example: a B2B company wants $2 million in new annual revenue, with $100,000 average new-customer revenue and a 25% opportunity win rate. It needs about 20 wins and 80 qualified opportunities. If 40% of sales-accepted leads become opportunities, it needs 200 accepted leads. At a fully loaded cost of $1,200 per accepted lead, the acquisition program needs about $240,000 before brand, retention, enablement, people and measurement. The calculation does not dictate the final budget; it reveals the assumptions the plan must satisfy.

Allocate the budget as a portfolio, not a channel wishlist

Separate the approved total into a protected base, growth bets, enablement and measurement. The base maintains proven revenue and essential brand presence. Growth bets target explicit segments or offers with a hypothesis and stop rule. Enablement funds sales assets, conversion, data quality and operating capacity. Measurement protects the evidence needed to move money. A reserve prevents every annual assumption from becoming politically permanent.

A 90-day budget operating rhythm

In the first 30 days, normalize the cost baseline and reconcile revenue, pipeline, funnel and margin assumptions. In days 31-60, assign each budget block to core, growth, enablement, measurement or reserve and define the evidence required for continuation. In days 61-90, run the first executive review: compare actual burn with qualified pipeline, contribution signals, learning velocity and operational constraints. Move money only when the decision rule is documented.

An annual budget can remain approved while quarterly allocation changes. This protects strategic consistency without preserving weak channel decisions. Version the assumptions, keep the all-in definition stable and show the difference between timing variance and true underperformance. Budget governance is not a monthly argument about every invoice; it is a repeatable way to fund evidence and stop low-confidence work.

1. Applying the 7.8% Gartner average to a smaller company without its sample caveat.
2. Calling media spend the marketing budget while excluding people and agency cost.
3. Copying last year's budget and adding an arbitrary growth percentage.
4. Funding every channel too lightly to produce a valid learning cycle.
5. Using attributed revenue without contribution margin or conversion lag.
6. Adding AI tools without workflow ownership, data readiness or quality control.
7. Approving a demand target that sales or fulfilment cannot absorb.
8. Treating every annual line item as permanent after evidence changes.
