SaaS Runway Calculator
SaaS runway calculator for founders who need a clear cash answer
Estimate how many months of runway your SaaS company has, how burn affects cash, and which levers extend your default alive timeline.
Formula: Runway = cash balance / monthly net burn
What is SaaS runway?
SaaS runway is the number of months your company can keep operating before cash runs out at the current burn rate. It is one of the fastest ways to understand fundraising urgency, hiring capacity, and whether growth is efficient enough to support the plan.
How Monter Pulse helps
Monter Pulse combines cash, operating costs, MRR, gross margin, growth, churn, expansion, and annual billing mix to show runway in context. Instead of only showing a cash-out date, it connects runway to default alive status, burn multiple, NRR, CAC payback, and founder action items.
When founders should check runway
Runway should be reviewed before hiring, fundraising, pricing changes, budget approvals, and monthly board updates. If runway drops below six months, the company is already inside the danger zone and should start immediate cash planning.
FAQ
What is a healthy SaaS runway?
Many early-stage SaaS companies target 12 to 18 months of runway, but the right benchmark depends on growth rate, fundraising market, burn efficiency, and whether the company is default alive.
Does revenue reduce burn?
Yes. Net burn is usually operating cash outflow after revenue contribution. Monter Pulse models revenue, gross margin, and operating costs together so runway reflects SaaS economics.
How do I extend runway?
Common levers include reducing non-essential spend, improving gross margin, increasing annual prepayments, lowering churn, increasing expansion revenue, and delaying hires that do not accelerate revenue.
