Introduction

Fund development is the strategic process of building and maintaining relationships to secure financial support for a non-profit organization’s mission. Effective fund development requires careful measurement and analysis to ensure that limited resources are used efficiently and that fundraising strategies are achieving their intended outcomes.

Key Performance Indicators (KPIs) provide quantifiable measures of success that help fund development teams track progress, identify areas for improvement, and make strategic decisions. While there are dozens of potential metrics that non-profit organizations could track, focusing on a core set of the most impactful KPIs allows for more effective analysis and action.

This guide presents the ten most important KPIs for fund development in non-profit charities, explaining what each metric measures, why it matters, how to calculate it, what target values to aim for, and how to implement it effectively.

1. Fundraising Return on Investment (ROI)

Definition

Fundraising Return on Investment (ROI) measures the efficiency and effectiveness of a non-profit organization’s fundraising efforts by comparing the funds raised to the costs incurred in raising those funds.

Formula

Fundraising ROI = Annual funds raised / Annual fundraising investments

Where:

Annual funds raised: Total monetary donations received through fundraising campaigns
Annual fundraising investments: Total costs associated with fundraising activities (staff time, marketing materials, event costs, etc.)

Why It’s Important

Fundraising ROI is a critical KPI for fund development because it:

Helps identify which fundraising campaigns and methods deliver the best returns
Enables strategic allocation of limited resources to the most productive fundraising activities
Provides concrete evidence to justify fundraising budgets to boards and leadership
Offers an objective metric for evaluating fundraising performance
Demonstrates to donors that their contributions are being used efficiently

Target Values

While ideal values vary by sector and fundraising method, general guidelines include:

Minimum acceptable: 1:1 (breaking even)
Good performance: 3:1 ($3 raised for every $1 spent)
Excellent performance: 5:1 or higher

Different fundraising methods typically have different ROI expectations:

Direct mail acquisition: Often 0.5:1 to 1:1
Direct mail renewal: Typically 3:1 to 5:1
Special events: Usually 2:1 to 4:1
Major gifts programs: Often 5:1 to 10:1 or higher

Implementation Tips

10. Lapsed Donor Reactivation Rate

Definition

Lapsed Donor Reactivation Rate measures the percentage of lapsed donors (those who previously gave but have not donated within a defined period) who resume giving following targeted reactivation efforts.

Formula

Lapsed Donor Reactivation Rate = (Number of reactivated lapsed donors / Total number of lapsed donors approached) × 100%

Where:

Number of reactivated lapsed donors: Former donors who made a new gift after reactivation outreach
Total number of lapsed donors approached: All lapsed donors who received reactivation communications

Why It’s Important

Lapsed Donor Reactivation Rate is critical for fund development because it:

Represents a more cost-effective strategy than acquiring new donors
Helps organizations maximize the value of their existing donor database
