Estimate how many months of runway your SaaS startup has based on cash, revenue, expenses, and planned hiring. The tool highlights cash-out timing, burn pressure, and fundraising urgency.
The result shows how long the company can operate before cash runs out. Longer runway gives more time to grow ARR, reduce burn, and raise capital from a stronger position.
Runway changes quickly when hiring, sales efficiency, churn, or revenue collection timing changes. Recalculate after every major operating decision.
With $1,200,000 cash, $100,000 monthly revenue, $220,000 expenses, and $20,000 hiring cost, net burn is $140,000 and runway is about 8.6 months.
Many SaaS startups aim for at least 12 to 18 months of runway, but the right amount depends on growth rate, fundraising market, burn efficiency, and stage.
Many founders start fundraising before runway falls below 9 to 12 months, because a funding process can take longer than expected.
Investors look at runway together with ARR growth, burn multiple, hiring plan, customer retention, and milestones achievable before the next round.
ARR growth can extend runway if revenue collection improves faster than expenses rise. Growth funded by heavy burn may not extend runway.
The answer depends on stage and market. Early SaaS companies may prioritize efficient growth, while later-stage companies often need stronger profitability discipline.
