The Enterprise Value to Revenue (EV/R) is a valuation metric used to compare companies in terms of relative value.

Enterprise Value to Revenue = Enterprise Value (EV) / Revenue

Example: If company A has an EV/R multiple of 10 ($100,000 (EV)/$10,000 (Revenue)), means that the company is currently valued at 10x revenue.

EV/R multiple can be used to value growth companies and firms that don't have positive earnings. Normally these companies are in an upstart phase or experiencing "hypergrowth".
