On average, it takes us anywhere from two to twenty hours to complete a grant proposal or application for a private foundation source. Typically, the first grant for a particular project takes the greatest number of hours, but time spent on each grant will depend on the quality and amount of the material supplied and input provided by the client, the type of questions on the application, the length of application, and the number and type of attachments required. For government submissions the time commitment is much greater and may take upwards of 100+ hours.
