How to Calculate Burn Rate for a Project
Project burn rate is a critical financial metric that tracks how fast a project team consumes its budget over a specific period, typically a month. Understanding your burn rate is essential for project managers, startup founders, and stakeholders to ensure that a project can be completed before financial resources are exhausted.
What is Project Burn Rate?
In project management, the burn rate represents the negative cash flow related to the project. It answers the question: "How much money are we spending per month to keep this project moving?"
It is comprised of various cost centers, including:
Labor Costs: Salaries for developers, designers, and project managers.
Infrastructure: Hosting fees, software licenses (SaaS), and cloud computing costs.
Overhead: Office space, utilities, and administrative support allocated to the project.
Why is Calculating Burn Rate Important?
Calculating your burn rate allows you to determine your Runway. The runway is the amount of time (usually expressed in months) you have left before the project budget reaches zero. Without monitoring this, projects risk abrupt stoppage due to lack of funds.
The Formula
To calculate the monthly burn rate, sum up all operational expenses for the month. To calculate the runway, divide your remaining budget by that burn rate.
