When measuring your social impact, the metrics you choose will depend on your sector, goals, and theory of change. Input metrics measure the resources and efforts that you invest in your innovation, such as time, money, staff, or materials. Output metrics measure the immediate results and deliverables of your innovation, such as products, services, customers, or users. Outcome metrics measure the changes and benefits that your innovation generates for your beneficiaries and stakeholders, such as behavior, knowledge, skills, or satisfaction. Impact metrics measure the long-term and systemic effects of your innovation on society and the environment, such as income, health, education, or sustainability. It’s important to select metrics that are relevant and meaningful for your sector and context as well as for your beneficiaries and stakeholders. For instance, if you’re innovating in the education sector you might use metrics like enrollment rates or graduation rates; if you’re innovating in the health sector you might use mortality rates or quality of life.
