Grounded Solutions Network created the Inclusionary Housing (IH) Calculator to help advocates, policymakers and other interested stakeholders understand the economic issues involved in designing an inclusionary housing policy. The IH Calculator is a simple on-line development pro forma which allows users to model a real or hypothetical development project and then add affordable housing requirements in combination with different development incentives. In this way users can get a sense of what might be economically reasonable for a given jurisdiction trying to set inclusionary housing requirements and offer developers meaningful incentives.This manual provides a general introduction on how to use the IH Calculator and provides guidance on basic real estate terms and key assumptions. As with the Calculator itself, this manual is meant to provide general guidance and is not a replacement for professional financial feasibility analysis.
