Many SSDI workers search for Trial Work Period rules and SGA limits at the same time. That usually means they are trying to keep better work records, not memorize technical language. The clearest approach is to understand what each term is for and track your work in a way that keeps them separate.
Both ideas relate to work while receiving SSDI, and both often come up in the same conversations. But they answer different planning questions. If your records are messy, everything starts to blur together. That is why a monthly work log helps.
TWP tracking is about reviewing work activity over time and keeping clearer records of the months you worked and what you earned.
SGA tracking is about comparing your monthly earnings with the threshold that matters to your situation.
Once those details are in one place, it becomes much easier to review TWP activity and monthly SGA comparisons without rebuilding your records from scratch.
A dedicated SSDI wage tracker gives you one place to log work, monitor monthly totals, and export your history later. That is often more practical than trying to explain the difference between TWP and SGA using a pile of spreadsheet tabs.
