Capex/Revenue Ratio

A metric showing the percentage of revenue a company reinvests into physical assets like property, plant, and equipment.

The Capex/Revenue Ratio measures the proportion of a company's sales revenue that is reinvested back into physical assets, such as property, plant, and equipment (PP&E). This metric is a key indicator of capital intensity, showing how much cash a business must plow back into tangible infrastructure to sustain or expand its operations. To calculate the ratio, an investor divides capital expenditures (Capex), found on the statement of cash flows, by total revenue from the income statement. A high ratio is common in asset-heavy sectors like utilities, telecommunications, and manufacturing, where continuous physical upgrades are required. Conversely, software and service companies typically exhibit low ratios due to their asset-light business models. Investors monitor this ratio to evaluate where a company sits in its lifecycle. A high or rising ratio often signals an aggressive growth or modernization phase, which can temporarily depress free cash flow and require external financing. If the ratio remains high without a corresponding increase in future revenue, it may indicate poor capital allocation or a business struggling to maintain its competitive position.

Company A generates $500,000,000 in annual revenue and reports $75,000,000 in capital expenditures on its cash flow statement. Its Capex/Revenue Ratio is calculated as $75,000,000 / $500,000,000 = 0.15, or 15%.
