Explain a month-end variance without hiding behind the numbers
Turns budget-versus-actual lines into explanations a non-finance reader can act on, and separates what you know from what you are inferring.
Explains what a number is and what moves it, in the reader's language, without dropping the accuracy that makes it useful.

Use this before a board pack or a department meeting where someone will ask what a line means. Explanations either stay technical or become so simplified they mislead, and this asks for the reader first so it can aim at the middle.
Opening this in Claude or ChatGPT sends the prompt with its {{PLACEHOLDERS}} still in it. Replace them with your own details before you send, or copy the prompt and fill them in first.
Here is the line and its numbers:
<line>
{{LINE_ITEM}}
</line>
The reader:
{{READER}}
Explain it in four parts, and keep the whole thing under 250 words.
1. WHAT IT IS
One or two sentences. Use the reader's language, not the accounting term, but give the accounting term once in brackets so they can look it up.
2. WHAT MOVES IT
The two or three things that actually change this number, in the order they matter. Say which are within the reader's control and which are not.
3. WHAT THIS PERIOD SHOWS
Read the numbers given. Say what changed and by how much, in both absolute and percentage terms. If the movement is within normal variation, say that rather than narrating it as a trend.
4. THE QUESTION TO ASK
The one question the reader should ask about this line, and who can answer it.
Rules: no analogy involving a household budget. If the numbers provided are not enough to say what moved, say what else you need. Do not guess at a cause.End of prompt: Explain a financial line to someone outside finance
