Marketing Budget Calculator: Size Your Marketing Budget by Stage, Model and Growth Ambition

Free tool by AAJ. The stage ranges are AAJ's working ranges, shown next to published reference points.

AAJ's Marketing Budget Calculator sizes a marketing budget from your business model, stage, growth ambition and the right base for your stage: quarterly burn at Pre-seed, the funding raised at Seed, and annual revenue or ARR from Series A on. It runs the same rules as the AAJ marketing-budget-planning engine, and it refuses a number it cannot read rather than changing it.

Use the calculator at aajconsult.com/tools/marketing-budget-calculator. For the published surveys behind the reference points, read the Marketing Budget Benchmarks 2026 report.

How the calculator works

For B2B SaaS, each stage has one of AAJ's working ranges, a planning view rather than third-party research: Pre-seed 30–60% of quarterly burn; Seed 10–20% of funding raised; Series A 20–30% of ARR; Series B 12–20% of revenue; Growth 15–25% of revenue; Mature 5–7% of revenue. Growth ambition (Conservative, Balanced, Aggressive) picks the low end, midpoint or high end. Ecommerce, services and marketplaces have no sourced stage range, so the calculator uses Gartner's 7.8% average of revenue unless you enter your own percentage.

It then splits the budget by function with AAJ's default split for your model, labelled as an assumption to edit, not a benchmark, and lists the published reference points: Gartner's 2026 CMO Spend Survey (budgets averaged 7.8% of company revenue, mostly at companies above $1B), SaaS Capital's 2026 survey (median private B2B SaaS marketing spend 8% of ARR) and Gartner's 2026 category shares (paid media 31.4%, martech 19.4% of the average budget). It does not check runway or affordability.

Frequently asked questions

How much should I spend on marketing as a percentage of revenue?

It depends on stage, and the base changes with it. AAJ's working ranges for B2B SaaS, a planning view rather than survey or client data, are: Pre-seed 30–60% of quarterly burn, Seed 10–20% of the funding raised, Series A 20–30% of ARR, Series B 12–20% of revenue, Growth (post-Series B) 15–25% of revenue, and Mature 5–7% of revenue. For comparison, SaaS Capital's 2026 survey puts the median private B2B SaaS company at 8% of ARR, and Gartner's 2026 CMO Spend Survey puts marketing budgets at 7.8% of company revenue, mostly at companies above $1B in revenue.

Why is a Seed budget sized against the round, not revenue?

At Seed, revenue is usually too small to be a useful base, and the money you are spending is the round. So the calculator, like the AAJ engine, sizes a Seed budget as 10–20% of the funding raised, spread across the round's runway. Pre-seed is sized against quarterly burn for the same reason.

What about ecommerce, services and marketplaces?

AAJ has no sourced stage range for those models. Without your own % of revenue, the calculator uses Gartner's 2026 average of 7.8% of revenue and says so: it is a large-company, cross-industry average, not a target for your stage. Enter your own % to plan at your level.

How is the budget calculated?

Base × percentage. The base is quarterly burn (Pre-seed), funding raised (Seed) or annual revenue (Series A on). The percentage is the low end, midpoint or high end of AAJ's working range for your stage, set by your growth ambition (Conservative, Balanced, Aggressive), or your own % of revenue if you enter one. The calculator runs the same rules as the AAJ marketing-budget-planning engine.

How should I split a marketing budget across functions?

The calculator shows AAJ's default split for your business model, labelled as an assumption to edit, not a benchmark. For B2B SaaS it is 45% demand gen (paid and events), 25% content and SEO/GEO, 12% brand and PR, 10% product marketing and 8% tooling and ops. For a published comparison, Gartner's 2026 survey puts paid media at 31.4% and martech at 19.4% of the average marketing budget.

How accurate are these ranges?

The stage ranges are AAJ's working ranges, not third-party research, and the page labels them that way. The published figures shown with them (Gartner 2026, SaaS Capital 2026) are averages across very different companies. Treat the result as a starting point, then check it against your runway and your unit economics: the calculator does neither.
