Determining Transaction Size Thresholds: Methods and Best Practices

The thresholds for categorizing transactions into labels such as "Small," "Medium," and "Large" are typically determined based on your specific business needs and data analysis. Here are some common methods to establish these thresholds:

1. Historical Data Analysis

• Review Past Sales Data: Analyze historical sales data to identify natural breakpoints in transaction amounts.

• Percentiles: Use percentiles to divide your data. For example, the 33rd percentile might be the upper limit for "Small," the 66th percentile for "Medium," and anything above that for "Large."

2. Business Objectives

• Revenue Goals: Set thresholds based on revenue targets. For instance, if you aim to increase the number of high-value transactions, you might set a higher threshold for "Large" transactions.

• Customer Segmentation: Define thresholds based on different customer segments. High-value customers might have higher transaction amounts, so the "Large" category could be set accordingly.

3. Statistical Methods

• K-Means Clustering: Use clustering algorithms to group transactions into categories based on their amounts.

• Standard Deviation: Calculate the mean and standard deviation of transaction amounts and set thresholds at certain standard deviations from the mean.

4. Industry Benchmarks

• Competitor Analysis: Look at industry standards and competitor benchmarks to set your thresholds.

• Market Research: Conduct market research to understand typical transaction sizes in your industry.

Example If you decide to use percentiles based on historical data:

• Small: 0 to 33rd percentile

• Medium: 34th to 66th percentile

• Large: 67th percentile and above
