How Much Should a B2B SaaS Startup Spend on Marketing?
The short answer: There is no single correct percentage. Many B2B SaaS companies at Seed to Series B spend roughly 10% to 30% of revenue on marketing, depending on growth targets, sales model and margin. The better question is what return each unit of spend must deliver and whether you can measure it. Treat benchmarks as a starting point, not a target.
Key takeaways
- Build the budget backwards from your revenue goal, deal size, win rate and CAC.
- Check CAC payback against your runway before committing.
- Put most spend on proven channels and protect a smaller share for tests.
- If you can't measure pipeline per unit of spend, invest in measurement before more spend.
Why is there no single right budget?
The right spend depends on growth goal, contract value, sales cycle, gross margin and runway. An enterprise product with a long cycle budgets very differently from a self-serve product.
What should the budget include?
- People: salaries, fractional leadership, freelancers, agencies.
- Programmes: paid media, events, content, partnerships.
- Tools: CRM, automation, analytics, reporting.
- Testing: a protected share for experiments.
Decide upfront whether people costs are inside the number so year-on-year comparisons stay clean.
How should you build it?
- Start from the goal. Take the revenue target, average deal size and win rate to find the pipeline marketing must contribute.
- Apply your CAC. Model what that pipeline costs. If it's unaffordable, change the plan, not the arithmetic.
- Check payback and cash. An 18-month payback is a different bet with 12 months of runway.
- Split proven from exploratory. Favour channels with evidence, and raise the test share when proven channels saturate.
How do you know you're spending well?
Track pipeline per unit of spend, CAC by channel, CAC payback and the share of pipeline marketing sources.
What mistakes should you avoid?
- Copying a benchmark without matching your model.
- Splitting budget evenly across channels.
- Cutting measurement and operations to fund campaigns.
- Giving agencies budget with no internal owner of strategy.
