| Field Name | Active Lines | Comment Lines | Density | Score |
|---|---|---|---|---|
| Profit Ratio | 5 | 1 | 16.67% | 91% |

Formula Used
Comment Density = Comment Lines ÷ Total Non Empty Lines × 100
Estimated Review Time = Active Lines + Half Comment Lines + Nesting Weight ÷ Reviewer Speed
Quality Score = 100 − Density Penalty − Nesting Penalty − Length Penalty
The calculator checks comment lines, active logic, operators, functions, and conditional depth. It compares the actual density with your target density. A balanced field has enough notes to explain intent without hiding the formula.
How to Use This Calculator
- Enter the calculated field name and reviewer name.
- Choose the logic type that best describes the formula.
- Set a target comment density for your team standard.
- Paste the calculated field with existing comments.
- Press the calculate button to review the result.
- Export the result as CSV or PDF for documentation.
Why Comment Quality Matters in Calculated Fields
Clear Logic Reduces Mistakes
Calculated fields often drive important dashboard numbers. A small formula change can affect totals, filters, ratios, and decision reports. Comments make the logic easier to check. They also help another analyst understand why a condition exists.
Good Comments Explain Purpose
A useful comment does not repeat every symbol. It explains the business reason behind the formula. It can mention assumptions, fallback rules, null handling, or special filters. This is important when a field uses ratio math, nested conditions, or date rules.
Balanced Density Is Important
Too few comments make a formula risky. Too many comments can make it harder to read. This calculator estimates comment density and compares it with a target value. A common target is between fifteen and twenty five percent. Complex formulas may need more notes.
Review Speed Helps Planning
Teams often review many fields before publishing dashboards. The review time estimate gives a quick planning number. It uses active lines, comment lines, and nesting depth. Deep logic takes longer because each condition must be checked against possible outcomes.
Scores Support Team Standards
The quality score is not a replacement for human review. It gives a fast signal. A high score means the field is clear and balanced. A low score means the formula may need better notes, fewer branches, or simpler structure.
Reusable Documentation
The export options help keep a record of field quality. You can save the result with dashboard notes, audit files, or internal tickets. This is useful when teams maintain shared workbooks. It also supports training because new users can study clear examples.
FAQs
What is a calculated field comment?
It is a note inside or near a formula. It explains why the logic exists, how values are handled, and what assumptions affect the result.
Can I use this for math formulas?
Yes. It works well for ratio formulas, conditional rules, totals, date calculations, and numeric dashboard fields that need readable notes.
What is a good comment density?
A useful range is often 15% to 25%. Very simple formulas need less. Complex nested logic may need more explanation.
Does the score prove the field is correct?
No. The score measures structure and documentation quality. You should still test the formula with real data and expected results.
Why does nesting depth matter?
Nested conditions create more paths to review. Each branch can change the output, so deeper logic usually needs clearer comments.
Can I export the review?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a formatted review summary.
Should every line have a comment?
No. Comment important decisions, assumptions, and edge cases. Avoid comments that simply repeat obvious operators or field names.
Can teams use one target density?
Yes. A shared target helps standardize reviews. Teams can adjust it for simple formulas, advanced calculations, or audit work.
