SaaS Runway & Burn Rate: Frequently Asked Questions
What is SaaS Cash Runway?
SaaS cash runway is the number of months your company can continue to operate at its current spending level before running out of money. It is a vital survival metric that helps founders understand their "zero cash date" and plan for future fundraising rounds.
What is the difference between Gross Burn and Net Burn?
Gross Burn is the total amount of cash your company spends each month on operating expenses (salaries, rent, software). Net Burn is the "true" loss: it is your Gross Burn minus your monthly revenue. Our calculator uses Net Burn to give you the most accurate view of your remaining runway.
How much runway should a SaaS startup have?
The industry standard for early-stage SaaS startups is typically 18 to 24 months. This provides enough time to hit key growth milestones, iterate on product-market fit, and allows for a 6-month buffer to close a new round of funding.
How do I calculate my runway if my revenue is growing?
For growing companies, a simple "static" runway calculation is often too pessimistic. You should use a "Growth-Adjusted Runway" which accounts for your month-over-month (MoM) revenue growth rate. As your MRR increases, your net burn decreases, naturally extending your runway.
When should I start fundraising based on my runway?
You should ideally begin the fundraising process when you have 6 to 9 months of runway left. This prevents "desperation pitching" and gives you the leverage to negotiate better terms while you still have a comfortable cash cushion.
What is a 'Burn Multiple' and why does it matter?
The Burn Multiple measures how much cash you are burning for every $1 of Net New ARR generated. A multiple of 1.0x to 1.5x is considered efficient for a SaaS company. Monitoring this alongside your runway helps ensure you are growing sustainably rather than just "buying" growth.
