Indianapolis Zoological Society Inc: $50.1M Revenue, $40.2M Expenses

The composite efficiency score of 56/100 puts Indianapolis Zoological Society Inc at C — neither standout nor failing. Some factors run above the median (often reserves) while others run below (often revenue stability or officer-comp ratio).

Indianapolis Zoological Society Inc reported $50.1M in 2023 revenue — a mid-sized nonprofit by U.S. standards. Organizations in this bracket typically operate with a small permanent staff, project-based program structures, and modest reserves. Reserves are the limiting factor: Indianapolis Zoological Society Inc carries relatively few months of operating expenses on its balance sheet, which can leave an organization exposed if a major funding source pauses.

Revenue trend is mildly positive across the five-year filing window — modest growth, consistent with stable funding sources keeping pace with organizational costs. Compensation for current officers and key employees runs $1.1M against $50.1M in revenue — within the band third-party charity raters typically consider reasonable for an organization of this size and complexity. This is an aggregate across all listed officers, not a single executive's salary. Indianapolis Zoological Society Inc works in Environment & Animals — environmental, conservation, animal-welfare, and natural-resources programs. The sector spans large international conservation groups and small local land trusts; the financial profile varies accordingly.
