Category questions

  • Where do the default values come from? They are illustrative numbers for a typical job so the page shows a worked answer. Replace them with your own measurements, datasheets and quotes before you rely on a result.
  • Why do some results show a warning? A warning means the plan fails a limit you entered or one from a cited source, such as your maximum defect rate, minimum bid margin or available labor hours. The message states the gap and what to change.
  • Can I download the calculation? Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.
  • Why is a result blank? An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.
