Magic number = (200,000 × 4) ÷ 400,000 = 800,000 ÷ 400,000 = 2.0

SaaS Magic Number and Sales Efficiency
Many founders search for the SaaS magic number sales efficiency definition because they want to understand how this ratio links to other metrics. The magic number is effectively a shortcut to see how quickly your sales and marketing spend pays back through new recurring revenue.
A low magic number means your CAC payback period is long and your sales engine is inefficient.
A high magic number means your spend converts into growth quickly and your payback period is short.
In that sense, the SaaS magic number definition benchmark is less about a single perfect value and more about whether your growth model deserves more capital.
Why Serious Investors Care About the SaaS Magic Number
Investors like this metric because it is:
Simple to calculate from your revenue and sales, and marketing lines
Comparable across different SaaS businesses
Forward looking, as it reflects how current spending translates to future growth
If the number is strong, the investor sees a company that can scale with additional capital. If the number is weak, even strong top-line growth can look dangerous because it may be driven by heavy spending that is not sustainable.
