Audubon Nature Institute Inc: $42.1M Revenue, $33.6M Program Expenses

The efficiency rubric puts Audubon Nature Institute Inc at a B grade: a composite of 73/100 that lands above the national midpoint. The grade reflects solid program-spending discipline alongside reasonable executive compensation and financial reserves.

At $42.1M in 2022 revenue, Audubon Nature Institute Inc sits in the mid-range of the U.S. nonprofit distribution. Most organizations of this scale operate regionally or focus on a single program area. Program-spending efficiency is strong: 80% of total expenses flow to program activities, above the 75% benchmark most third-party charity raters use.

Revenue trend is mildly positive across the five-year filing window — modest growth, consistent with stable funding sources keeping pace with organizational costs. CEO compensation is reported as zero in the filing — typical for nonprofits where the chief executive is paid through a related entity (parent system, university, or foundation) rather than the filing organization itself, or for small organizations whose chief is a volunteer or board member. Audubon Nature Institute 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.
