Not all donations are equal. A dollar donated to the most effective animal charities can do 100x or more the good of a dollar donated to a less effective organization. Here's what the research shows.
Based on Animal Charity Evaluators' research. Numbers are estimates and vary, but the relative differences are substantial.
| Organization | Type | Animals helped per $1,000 | Primary Mechanism |
|---|---|---|---|
| The Humane League | Corporate campaigns | 100,000–1,000,000+ | Cage-free & better welfare commitments from food companies |
| Mercy For Animals | Corporate + investigations | 50,000–500,000+ | Corporate welfare commitments, legal advocacy |
| Good Food Institute | Research & development | Systemic (hard to quantify) | Making plant-based & cultivated meat viable alternatives |
| Typical local shelter | Direct care | ~5–50 | Adopting/treating individual animals |
| Pet food/toy purchases | Commercial | ~0–1 | Primarily benefits companion animals of donors |

Illustrative estimates for donations to top effective charities:
Estimates based on ACE's cost-effectiveness analyses. Impact is uncertain but consistently orders of magnitude higher than most charitable giving options.
Why do organizations like The Humane League have such high estimated impact?
A single successful campaign with a major food company (McDonald's, Walmart, Costco) can result in commitments covering tens of millions of animals per year. These commitments persist for years.
The Humane League's "Open Wing Alliance" has won commitments from 1,000+ companies globally since 2016, including every major US food service company. These represent real changes, not just promises.
When Whole Foods commits to cage-free, it pressures other retailers. When McDonald's commits, it changes supplier incentives across the entire industry. One win creates cascading effects.
Highest estimated cost-effectiveness for farmed animals. Transparent, evidence-driven, scrappy corporate campaigns.
