Calculate cost of revenue consistently, including hosting, third-party services, customer support, success, and delivery costs. Track unit costs per user or transaction, and model economies of scale. When margin dips, investigate architectural inefficiencies, support backlog, or contract terms inflating infrastructure spend.
Combine growth rate and operating margin to gauge balance, but layer stage, market, and capital conditions before drawing conclusions. Early companies might prioritize growth; later stages reward efficiency. Use the metric to provoke strategy debates, not to enforce one-size-fits-all decisions.
Compare net burn to net new ARR to understand how efficiently cash becomes durable revenue. Maintain a forward view of cash runway under multiple scenarios, then align hiring, marketing investments, and roadmap bets with the efficiency signature you want investors and employees to recognize.
