SaaS Contribution Margin: Discover Where Your Money Maker Lies
by OpenView Partners

Knowing your contribution margin is about capital discipline. Do you know where you’re spending your money? Are you mindfully investing it into the future of the business, or is the spending on autopilot? More than a simple formula, calculating contribution margin is an investigation. It reveals where the work is happening and why…A contribution margin is a snapshot in time, and a fully loaded contribution margin takes into account the following:
