The Foundation distributes mosquito nets to protect the people from the disease in the malaria-active areas of 36 countries. For $ given, the charity covers all the costs (1) of protecting persons with nets for a year (2). This results in health benefits for an average of (3)(4). The health benefits also bring (by increasing labor force). The poverty reduction generates an increased well-being (5), that can be expressed as for which someone's happiness is increased by 50%.

Health and education benefits translate into (higher-pay jobs + more labour force)(10)(11).The poverty reduction generates an increased well-being (5), that can be expressed as for which someone's happiness is increased by 50%.

Ugastove Project

The organization sells energy-efficient stoves in Uganda founded at 75% by your donation. For $, stoves are financed and distributed (13). Those stoves will save in the next 7 years (14). Spared charcoal/wood represents (14)(15) which will further increase a household's happiness by 50% for (5).

(4) For calculations, the Givewell's model of 2016 restricts first to children saved <5 (a majority of nets distributed), whose average life expectency in perfect health (QALE) is 30 in the poorest countries (where nets are given). Then, the 2017 model takes partially into accounts the adults protected.
