The implementation of a community garden of about 6000 square metres costs around 33 000 USD. This includes working devices (e. g. spades and hoes), irrigation system and sun protection, measures of soil improvement such as organic fertilizer and humus, construction timber for the compost heap and planting beds, plants, seeds, petrol for the delivery of materials and machines, and personnel costs for two agricultural engineers who help residents create the garden. Costs vary depending on the size of the garden. 

The implementation of the community gardens is financed through donations from private and public persons and foundations. In 2015, a German branch was founded in Berlin (Städte Ohne Hunger Deutschland e. V.) with the objective to support Cities Without Hunger's work in Brazil financially and public relations work abroad, especially in Germany, but increasingly at an international level. 

After one year, community gardens are self-supporting. Gardeners earn their income selling their produce. Cities Without Hunger still provides technical support and lends bigger machines like tractors when needed. The NGO also supports network-building actions to integrate the gardens in São Paulo's wider economy, e. g. through delivery partnerships with restaurants.
