- Formula
- =IFERROR(ROUND((D2-C2)/C2,2),"Check input")
- Workbook context
- C is last month's revenue, D is this month's revenue. The cell should show the decimal growth rate rounded to two places.
- Sample values
- C2=8000; D2=9200.
Understand what a formula calculates, its dependencies, and where it can fail. Forneça: Formula, Workbook context, Sample values. Resultado esperado: A plain-language walkthrough, worked example, and risk checklist.

Explain this Excel formula without changing it:
[formula]
Workbook context:
[context]
Sample values:
[sample]
Return:
- A one-sentence description of the final result
- A nested breakdown evaluated from the innermost operation outward
- A worked calculation using the sample values
- Every cell, range, table, or named-range dependency
- The meaning of absolute and relative references
- Likely failure modes involving blanks, text, errors, dates, or missing matches
- Two questions to confirm with the workbook owner

Result: The formula calculates month-over-month revenue growth as a decimal, rounds it to two places, and replaces any calculation error with “Check input.”
Inside out: D2-C2 finds the revenue change. Dividing that change by C2 expresses it relative to last month. ROUND(...,2) keeps two decimal places. IFERROR catches every Excel error from the calculation.
Worked example: 9,200 − 8,000 = 1,200; 1,200 ÷ 8,000 = 0.15; rounding gives 0.15, which displays as 15% only if the cell uses percentage formatting.
Dependencies: C2 and D2 only. Both are relative references, so copying the formula down changes them to C3/D3, then C4/D4.
Failure modes: C2 equal to zero triggers the fallback; numeric text may behave inconsistently; blanks can be treated as zero; IFERROR hides the difference between a zero denominator and corrupted input. Confirm whether zero prior revenue should show “new” rather than an error, and whether blank current revenue means zero or missing data.
Working from the inside out makes nested formulas easier to audit.
A real sample distinguishes a plausible explanation from the formula's actual behavior.
Can you reproduce the worked result manually?
Are all external sheets, ranges, and fixed references identified?

Respostas práticas sobre quando usar esta receita, o que fornecer e onde a revisão humana ainda é importante
For “Explain an Excel formula step by step,” prepare Formula, Workbook context, and Sample values. Replace placeholders only with information you can verify. If a detail is unknown, preserve that uncertainty explicitly instead of asking the model to infer it.
The result is not ready if it does not yet deliver the stated outcome—A plain-language walkthrough, worked example, and risk checklist—from the supplied evidence, or if it relies on unresolved assumptions, missing approvals, or invented details. Use the checks as release gates: revise the source inputs or assign a named, authorized reviewer instead of polishing an unsupported output.
The published test record for “Explain an Excel formula step by step” lists ChatGPT as of 2026-08-28. This confirms recorded runs, not guaranteed compatibility or identical results in later product versions. For another tool or version, keep every constraint visible and repeat the result checks before use.
