Capital Output Ratio Calculator
Divide a capital stock by annual output on a consistent valuation basis.
Use a nonnegative capital stock and positive annual output with the same currency, scale and price basis. State the reference year and whether each measure is gross or net; do not silently combine inconsistent definitions. K/Y is a stock-to-flow ratio measured in years when Y is per year. It is not ICOR (investment divided by change in output), a causal productivity measure or a cross-country ranking. Capital stock estimates can contain substantial measurement error.
