Minimum Wage Multiple (OI6176)

This metric is intended to capture the average non-salaried wage paid to employees of the organization as a multiple of the local minimum wage during the reporting period. Organizations may use a variety of timeframes to calculate the average non-salaried wage (such as hourly, weekly, or daily) and should use the same time period when comparing wages to the local minimum. For example, if the minimum wage in a given area is based on an hourly rate, the average wage should also be hourly.

Organizations should footnote the source of the local minimum wage used to calculate this ratio. Organizations can refer to the definition of minimum wage in the glossary for more resources on where to find minimum wages by various geographies.

Organizations are encouraged to narrow the calculation of this ratio to specific geographies, industries, departments, or positions, and organizations should footnote details on how the calculation was done.

In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
