Metrics & Performance

Quick Answer
The number of months a company can continue operating at its current burn rate before running out of cash. One of the most critical metrics for managing fundraising timing and operational survival.
Runway is the amount of time a company has before it exhausts its cash reserves, calculated by dividing current cash balance by the monthly net burn rate.
Runway (months) = Cash Balance / Monthly Net Burn Rate
For example, a company with $2.4M in the bank burning $200K/month has 12 months of runway. Runway is the most important operational constraint for a startup — it determines when fundraising must happen and how much operational flexibility exists.
Founders should always know their runway to the day. Running out of cash is the primary cause of startup failure that isn't due to market or product failure.
In Practice
A company has $3M in the bank. Its monthly cash outflows are $350K (salaries, infrastructure, marketing) and monthly revenue collections are $150K. Net burn = $350K - $150K = $200K/month. Runway = $3M / $200K = 15 months. Given that fundraising typically takes 3-6 months, this company should begin serious fundraising immediately if it hasn't already.

Why It Matters
Runway management is one of the most critical CEO responsibilities. Most experienced founders maintain 12-18 months of runway at all times. Starting a fundraise with less than 6 months of runway puts founders in a desperate negotiating position. The best investors can smell runway pressure — and it affects your valuation and terms significantly.
VC Beast Take
The rookie mistake is managing to the average burn scenario. Smart founders model three scenarios: base case (current trajectory), optimistic (revenue acceleration), and worst case (revenue stalls, unexpected costs). Worst-case runway should always be at least 6-9 months. Extend runway by reducing burn before starting a raise — it's better to show controlled spending and 18 months of runway than high burn with 9 months left.
