How Magic Number Works
The magic number reveals the true performance of a SaaS company's go-to-market strategy by calculating the relationship between sales and marketing expenses and new annual recurring revenue (ARR).
Calculated by dividing net new ARR in the current quarter by sales and marketing spend from the previous quarter, this metric cuts through vanity metrics to expose the real efficiency of growth investments.
While a magic number of 1.0 represents ideal efficiency (one dollar of new ARR for every dollar spent), context matters more than the absolute number—industry, market maturity, and business model all influence interpretation.
