Rating Trace
Review every rule, formula, lookup table, underwriting decision, and premium calculation executed by the commercial insurance rating engine.
When a premium changes unexpectedly, the most common question is simple:
What changed?
Most legacy rating systems provide only the final premium. They do not explain how the premium was calculated, which rules executed, which formulas were evaluated, or why pricing changed. SelectRate Rating Trace records every calculation, every business rule, every lookup table, every underwriting decision, and every pricing adjustment executed during the rating process. Instead of troubleshooting by guessing, insurance organizations can replay every calculation exactly as it occurred.
What Is Rating Trace?
Rating Trace is a complete execution log of every calculation performed by the commercial insurance rating engine.
The trace records:
- Input Variables
- Formula Execution
- Rule Evaluation
- Lookup Tables
- Bureau Rates
- Carrier Adjustments
- Underwriting Decisions
- Premium Changes
- Final Premium
Every calculation step is permanently recorded.
Rating Trace vs Rating Worksheet
A Rating Trace records every execution step performed by the Insurance Rating Engine. A Rating Worksheet summarizes the final premium calculation. Use Rating Trace to understand how the engine reached a decision. Use the Rating Worksheet to review the completed premium calculation.
