What Helps Us Help You Faster
For calculation errors, the most useful thing you can include is your specific inputs and what result you got versus what you expected. "The mortgage calculator seems wrong" is hard to trace. "I entered $450k loan, 30 years, 6.8% — it showed $2,940/month but I'm getting a different number elsewhere" is something we can actually investigate. Same applies for methodology questions: the more specific, the faster we can dig in.
