The importance of understanding your donors’ motivations, needs, preferences, and giving patterns cannot be overstated. Gaining insight into all these factors gives you the ability to tailor your outreach in a way that resonates with each individual supporter and connect with them on a deeper level.  

Enter donor segmentation — a strategic framework that allows you to categorize and group your donors based on shared characteristics so that you can craft personalized messaging instead of resorting to a one-size-fits-all approach.

One incredibly effective segmentation tool borrowed from the corporate world is RFM (Recency, Frequency, Monetary) analysis. 

This method helps you delve deeper into donor behavior and allows you to cultivate lasting relationships with your constituents and inspire even greater generosity.

In this post, we’ll break down the ins and outs of RFM donor segmentation, as well as explore how it works, why it’s so valuable, and how you can implement it to boost your fundraising efforts.

What Is the RFM Donor Segmentation Model?

At its core, RFM is a simple yet insightful model that dissects donor engagement based on the following three key metrics: 

  • Recency (R). When was the last time a donor contributed? Recent donors are often considered more likely to give again compared to those who haven’t donated in a while.
  • Frequency (F). How often does a donor contribute? Frequent donors demonstrate consistent support and a stronger connection to your cause.
  • Monetary Value (M).  How much does a donor typically give? Donors who have given larger amounts in the past may possess the potential for greater giving capacity.


Simply put, recency measures how much time has passed since a donor’s last contribution. It serves as a critical indicator of their current level of engagement with your university. You can expect a donor who recently contributed to give again, while the odds for someone who last donated years ago are significantly lower. Of course, you can (and should) build a fundraising cadence for lapsed donors and try to reengage them. 

Determining what “recent” means for your organization is crucial for accurate RFM analysis. Although this metric can vary based on your institution’s specific context, a six-month period often strikes the right balance. It’s long enough to avoid donor fatigue while accounting for natural fluctuations in giving patterns throughout the year. 

On the other hand, a period shorter than this could lead to overly frequent solicitations, potentially decreasing donation amounts and increasing donor attrition.

So, the trick is to strategically define your recency parameters and incorporate them into your RFM analysis. This knowledge empowers you to develop targeted communication strategies, personalized appeals, and tailored stewardship initiatives. 

Remember, the optimal recency timeframe can vary, so experiment and find what works best for your organization.


Simply knowing when a donor last gave won’t cut it — how often they give is crucial for identifying their level of engagement and commitment to your cause.

For instance, a donor who consistently gives $50 every six months for five years demonstrates a higher level of engagement compared to someone who only recently made their first $50 donation. You don’t have much historical data to determine the future timeline of their donations, so it’s important to bear this in mind when creating your messaging for them. 

Frequency is a strong predictor of long-term fundraising success. Statistics reveal that increasing your donors’ giving frequency, especially in terms of second-gift conversions, can lead to a more dedicated and engaged donor base. This makes the “F” in RFM a valuable metric to track and analyze.

However, it’s worth noting that donors who stick to a strict giving schedule, such as monthly donors, might not be the ideal candidates for RFM segmentation. It’s often better to treat them as a separate segment and focus on encouraging them to increase their monthly contribution when appropriate.

Monetary Value

The monetary value aspect of RFM helps you calculate the total amount a donor has contributed to your organization over a specific period. 

This metric allows you to pinpoint your most valuable donors — those who have consistently shown significant financial support. By understanding the monetary value of your donors, you can tailor your stewardship efforts accordingly. 

For example, high-value donors might receive personalized thank-you notes, invitations to exclusive events, or even opportunities to engage directly with your organization’s leadership. Recognizing and appreciating their generosity is crucial for maintaining their continued support. Additionally, you can use this metric to explore your constituents’ giving potential and figure out if it’s possible to move some of them to, for example, the mid-level or major donor segment. 

To accurately assess a donor’s monetary value, it’s best to calculate their median gift size over a reasonable period. Using the median rather than the average or total amount helps to mitigate the impact of outlier gifts, either unusually large or small, that don’t truly reflect a donor’s typical giving behavior.

The Best Practices for Implementing RFM

Here’s a round-up of some factors and best practices that will allow you to truly harness the power of RFM analysis and unlock its potential for your fundraising efforts: 

Data collection

Collecting and managing data makes all the difference when it comes to successful RFM segmentation. It’s critical to keep your donor records accurate and comprehensive. 

Ensure your CRM or database is meticulously maintained, including up-to-date donation histories, contact information, and engagement levels. 

Tracking not only donations but also interactions such as event attendance, volunteer hours, and email opens to gain a holistic view of each donor goes a long way toward making informed decisions.


Develop a clear and consistent scoring system for each RFM parameter. 

This can be done using a numerical scale (e.g., 1-5) or by creating custom categories (e.g., high, medium, low). 

The choice depends on your organization’s specific needs and preferences. To ensure objectivity and consistency, clearly define the criteria for each score or category.


Once you have assigned RFM scores, group your donors into distinct segments based on their scores and label them. 

The number of segments you create will depend on the size and complexity of your donor base. 

Start with broader categories like “active,” “lapsed,” and “major donors,” and then refine them further.


Dig deeper into each segment to understand their unique characteristics. 

Analyze demographic data, interests, communication preferences, and giving patterns to identify trends and insights. Make sure your fundraisers record all the relevant information about individual donors they discover during calls. 

For example, learning that a donor has two kids in college can be a sign that you can’t expect sizable contributions from them within the next four years. This analysis will guide your fundraising strategies and messaging for each segment.


RFM segmentation is not a static process. Regularly evaluate your model to ensure its continued accuracy and effectiveness. 

As your donor base evolves, you may need to adjust your segmentation criteria or scoring system. Stay attuned to changes in donor behavior and adapt your strategies accordingly.

Additional tips

  • Leverage technology. Consider using donor engagement software or CRM platforms to streamline the process and automate data analysis. Paired with the Engagement Center concept, you’ll be able to take your donor loyalty strategies to the next level.
  • Start simple. If you’re new to RFM, begin with a basic model and gradually refine it as you gain experience and insights.
  • Collaborate. Involve your entire fundraising team in the RFM process to foster a shared understanding of your donors and develop holistic strategies.
  • Experiment. Don’t be afraid to experiment with different segmentation criteria and messaging approaches to find what works best for your organization.
  • Focus on relationship building. Remember, RFM is just a tool. Use it to inform your donor engagement strategies, cultivate meaningful, long-lasting relationships with your supporters, and go beyond generic appeals and mass emails.
  • Combine RFM with other donor intel. To create a more comprehensive view of your supporters, you can integrate RFM data with other donor information. For example, demographics such as age, gender, or location can provide valuable insights into donor motivations and preferences. Donor interests are equally crucial as these let you in on what causes or programs your donors are most passionate about. Understanding their interests can help you personalize your communication and allow you to offer them the most relevant content. 

By combining RFM with other relevant data, you can create even more nuanced donor segments and tailor your fundraising strategies with even greater precision.
