The 80/20 Rule in Fundraising: Why a Few Donors Matter Most

Fundraising does not always grow evenly. A small group of donors may contribute a large share of an organization’s total donations. This idea is often explained using The 80/20 Rule in Fundraising, based on the Pareto Principle.

In Simple Terms: The 80/20 rule suggests that roughly 80% of results can come from 20% of the causes. In fundraising, this can mean that a smaller group of donors provides a large part of the funds.

Some donors give larger or more frequent donations, making them important to fundraising efforts.

Building strong relationships with these supporters can help organizations maintain long-term support.

Important: The 80/20 split is not a fixed rule. The actual percentage can be different for every organization.

The principle can help fundraising teams decide where to focus their time and resources.

Build Strong Donor Relationships

Keep major supporters engaged through personal communication, updates, and regular appreciation.

Find Your Most Valuable Donors

Keep Smaller Donors Engaged

Smaller donors also matter. They can continue supporting campaigns and may become larger contributors over time.

When donors choose to support a cause online, following simple safe online donation practices can also help them make informed contributions.

Every Donor Matters: Major donors provide significant support, while smaller donations help build a wider donor community.

You can start with a simple review of your donor data:

How to Apply the 8020 Rule
  1. List your donors and their total contributions.
  2. Sort the donations from highest to lowest.
