How to use this calculator

  • Enter current cash balance.
  • Add monthly revenue, monthly expenses, and planned hiring cost.
  • Review runway months and whether fundraising should start soon.

What the result means

The result shows how many months the startup can operate before cash runs out. Longer runway gives founders more control and negotiating leverage.

Net burn = monthly expenses + planned hiring cost − monthly revenue. Runway = cash balance ÷ net burn.

If net burn is zero or negative, the calculator treats the company as effectively profitable for runway purposes.

Example calculation

With $1,000,000 cash and $50,000 net monthly burn, runway is 20 months.

Tips for better results

  • Start fundraising before runway falls below 9–12 months.
  • Model hiring decisions before making offers.
  • Cut low-return expenses before runway becomes urgent.

FAQ

How many months of runway should a startup have?

Many VC-backed startups target 18–24 months of runway after a round.

When should founders raise another funding round?

Founders often start raising when runway is still long enough to avoid weak negotiation leverage.

What is considered a healthy startup runway?

Healthy runway depends on stage, but under 12 months usually creates urgency.

How do investors evaluate startup runway?

Investors evaluate runway alongside burn rate, growth, milestones, and fundraising plan.

How can I extend my startup runway?

Extend runway by increasing revenue, slowing hiring, cutting low-return spend, or raising additional capital.
