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.
Why a Few Donors Can Matter More
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.
How the 80/20 Rule Helps Fundraising?
The principle can help fundraising teams decide where to focus their time and resources.

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

Every Donor Matters: Major donors provide significant support, while smaller donations help build a wider donor community.
How to Apply the 80/20 Rule?
You can start with a simple review of your donor data:

- List your donors and their total contributions.
- Sort the donations from highest to lowest.
- Calculate the total amount raised.
- Identify the group contributing the largest share.
- Plan more personalized engagement for those donors.
