Frequently Asked Questions

Runway is estimated by dividing available cash by monthly net burn. This calculator can also model month-by-month changes from revenue growth and expense growth, so the result may differ from a simple static division.

Many teams aim for 18–24+ months after a financing round, but the right target depends on growth rate, funding environment, sales cycle and ability to reduce burn quickly.

Burn multiple compares net burn to net new ARR. A lower value means the company is generating more recurring revenue for each dollar burned; a very high value can signal inefficient growth.
