## How Much Should B2B SaaS Spend on Demand Generation? (2026 Budget Framework)

**B2B SaaS demand generation budgets** should be 8–12% of target annual recurring revenue (ARR) for growth-stage companies in 2026. A company targeting $5M ARR should invest $400K–$600K annually ($33K–$50K/month) in combined demand gen and lead gen. The formula: target ARR × 8–12% = total marketing budget. Then split 60/40 between demand gen (brand awareness, content, LinkedIn, ABM) and lead gen (Google Ads, conquesting, demo pages).

According to SaaS Capital’s 2025 Spending Benchmarks, the median SaaS company spends $2.00 to acquire $1.00 of new ARR — up 14% from 2023. According to OpenView’s 2025 SaaS Benchmarks, top-quartile companies spend 40–60% of revenue on sales and marketing during growth phases. Companies spending significantly below 8% of target ARR consistently underperform on pipeline targets.
