Burn rate is the speed at which a company spends its cash reserves, measured monthly. For SaaS product and operations teams, burn rate is the financial context that governs headcount decisions, tool budgets, and the pace of product investment. Understanding burn rate is essential for any leader making resource prioritization decisions.

What is the difference between gross burn and net burn rate?
Gross burn rate is total monthly operating expenditure — the sum of all costs regardless of revenue. Net burn rate is gross burn minus monthly revenue — the actual cash consumed, accounting for what the business earns. Net burn is the more practically relevant metric: a company spending $500k/month with $400k in revenue has a net burn of $100k/month, not $500k. As ARR grows, net burn shrinks (or flips to net positive — cash flow positive). This trajectory from high net burn to breakeven to profitable is the fundamental financial narrative of a SaaS business, and Product Ops must understand where the business is on that journey when advocating for engineering headcount or product infrastructure investment.

How does burn rate affect product and support operations decisions?
Burn rate creates the context for prioritization decisions. At high burn with limited runway (< 18 months), prioritization must ruthlessly focus on revenue-impacting work: features that unlock new ARR or reduce churn, support processes that enable CS to manage more accounts with fewer headcount additions. Tool procurement is scrutinized — a $50k/year analytics platform requires a clear ROI case. At low burn or profitability, teams can invest in longer-horizon bets: platform modernization, exploratory research, quality improvements that compound over time. Product Ops models the headcount and tooling cost of roadmap scenarios against the burn envelope before presenting resource requests to leadership.

What is runway and how does it relate to product planning horizons?
Runway = cash balance / net monthly burn rate. It represents the number of months the company can operate without additional funding or reaching profitability. Runway directly constrains product planning horizons: with 12 months of runway, the product plan must have a clear revenue impact within 6 months (leaving buffer for fundraising). With 36 months, the team can reasonably invest in 12–18 month platform investments. Product Ops should factor runway into roadmap planning by ensuring that at least 60% of near-term roadmap work connects directly to ARR retention or growth, with the remaining capacity allocated to foundation and exploration work.
