Roll Rate Calculation

Define Credit Stages

Clearly outline the credit stages relevant to your analysis. These stages typically include various levels of delinquency, ranging from current and 30 days overdue to more severe statuses. Establishing clear distinctions between these stages forms the foundation for accurate Roll Rate Analysis.

Gather Data

Accumulate comprehensive datasets that encompass transitions between credit stages over a defined period. This dataset should include information on customer accounts, payment histories, and any relevant factors influencing credit movement. The richness of your data directly correlates with the depth of insights gained from the Roll Rate Analysis.

Calculate Transition Rates

Utilize the gathered data to compute transition rates between credit stages. Transition rates represent the percentage of accounts moving from one stage to another within a specific timeframe. The formula for calculating transition rates is straightforward:

Transition Rate=Number of Accounts Transitioned/Total Number of Accounts in Previous Stage×100

Repeat this calculation for each credit stage transition, providing a comprehensive view of how accounts progress or regress over time.

Roll Rate Analysis Calculation: A Comprehensive Guide

Roll Rate Analysis involves a systematic calculation of the transition rates between different credit stages, providing valuable insights into the movement of accounts over time. Here’s a step-by-step guide on how to perform Roll Rate Analysis:

Define Credit Stages

Begin by clearly defining the credit stages relevant to your analysis. These stages typically include various levels of delinquency, such as “Current,” “30 Days Overdue,” “60 Days Overdue,” and so forth. Each stage represents a distinct point in the credit lifecycle.

Gather Data

Collect comprehensive data sets that capture the transitions of accounts between the defined credit stages. The data should include information on account identifiers, timestamps, and the current and subsequent credit stages for each account.

Calculate Transition Rates

Use the gathered data to calculate the transition rates between credit stages. The formula for calculating the transition rate from one stage to another is:

What is the Roll Rate Analysis Formula?

Roll Rate= Total Number of Accounts/ Number of Transitions

What is Transition Rate?

Number of Accounts Transitioned to Next Stage/Total Number of Accounts in Current Stage × 100

Repeat this calculation for each relevant credit stage transition. This process provides a series of transition rates that indicate the percentage of accounts moving from one stage to the next within the specified time frame.

Aggregate and Visualize

Aggregate the calculated transition rates to gain a holistic view of the overall Roll Rate Analysis. Utilize visualization tools, such as charts or graphs, to present the data in a clear and understandable format. Visual representations enhance the interpretation of trends and patterns within the roll rates.

Example Calculation:

Suppose you are analyzing the transition from the “Current” stage to the “30 Days Overdue” stage. If, out of 500 accounts in the “Current” stage, 20 transitions to the “30 Days Overdue” stage, the calculation would be:

Transition Rate

20/500*100= 4%

Repeat this process for each credit stage transition relevant to your analysis.

Roll Rate Analysis in Data Science: Practical Examples

Roll Rate Analysis is a powerful tool in the realm of Data Science, providing actionable insights into patterns and trends within financial data. Here are real-world examples showcasing how Roll Rate Analysis is applied in Data Science:
