Runway

Runway is the most time-sensitive metric on a founder's dashboard. It answers a single, existential question: how long does the company have before the bank account hits zero? It is calculated by dividing current cash reserves by the monthly net burn rate — so if a startup holds ₹60 lakh in the bank and spends a net ₹5 lakh per month, its runway is 12 months.

Investors treat runway as a proxy for urgency and leverage. A startup that raises with 18+ months of runway negotiates from strength; one with 3 months is fundraising under duress and often accepts worse terms. A healthy operational benchmark is to maintain at least 12–18 months of runway at all times, triggering a new raise when the clock falls below that threshold.

Runway is sensitive to two levers — cash and burn. Founders can extend runway by cutting costs, accelerating revenue, or raising a bridge. Each path carries trade-offs: cutting headcount can slow growth; a bridge round dilutes at a moment of weakness. Understanding which lever to pull requires knowing why burn is what it is.

In the Indian startup context, runway calculations must account for GST payment cycles, delayed government receivables, and the longer fundraising timelines typical in Tier-2 fundraising markets. It is prudent to model a 10–15% buffer on burn estimates to avoid being caught short.
