Finance prompt of the day

October 13, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are an FP&A analyst writing the budget-vs-actual commentary for [COMPANY / UNIT] for [MONTH], using the actuals, budget and prior-year figures I paste below. Produce:
1. A VARIANCE TABLE by P&L line: actual, budget, variance in currency and percent, and prior-year comparison, computed only from my figures.
2. MATERIALITY: comment only on lines over the threshold I set (default: 5% and [AMOUNT], whichever is larger) and list the rest as "within tolerance".
3. For each material line: the driver (volume, price, mix, cost rate, timing, one-off), stated as a hypothesis where my inputs do not prove it, plus the evidence I should pull to confirm it.
4. TIMING vs PERMANENT: classify each variance and say which ones should flow into the full-year reforecast.
5. A five-sentence summary for leadership, bottom line first, with no adjectives that the numbers do not support.
Here is my data:
[PASTE: month and year-to-date actuals, budget, prior year by line; known one-offs; materiality threshold]

Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it. Mark every claim I should verify externally before relying on it. Never use, infer, or request material non-public information (MNPI) or client-confidential data.

What changed for Finance

How to run “Budget vs actual variance commentary for the month-end close”, step by step

The situation this prompt is built for: The month has closed and leadership wants to know what moved versus budget, why, and whether it changes the full-year outlook. Below is exactly what to feed it and what comes back — no model-specific tricks, it runs the same in any chat AI.

What each placeholder does

Demo profile for the example fills: an equity research associate on a mid-cap sector coverage team, working in Excel, a chat AI model, and your firm's data terminal. Swap in your own context — or save it once at /profile and copied prompts arrive pre-filled.

• [COMPANY / UNIT] — this is the input the whole output quality hangs on. Each part narrows the answer: company; unit. Demo fill: what you sell in one plain sentence, plus who buys it. Leave it vague and the model pads with boilerplate; make it concrete and every section downstream sharpens.
• [MONTH] — this is the input the whole output quality hangs on. Demo fill: your own month — one or two concrete lines beats a paragraph of vague context. Leave it vague and the model pads with boilerplate; make it concrete and every section downstream sharpens.
• [AMOUNT] — this is the input the whole output quality hangs on. Demo fill: your own amount — one or two concrete lines beats a paragraph of vague context. Leave it vague and the model pads with boilerplate; make it concrete and every section downstream sharpens.

What the model hands back

The prompt forces a fixed deliverable shape, so you get a document, not a ramble:

1. A VARIANCE TABLE by P&L line: actual, budget, variance in currency and percent, and prior-year comparison, computed only from my figures.
2. MATERIALITY: comment only on lines over the threshold I set (default: 5% and [AMOUNT], whichever is larger) and list the rest as "within tolerance".
3. For each material line: the driver (volume, price, mix, cost rate, timing, one-off), stated as a hypothesis where my inputs do not prove it, plus the evidence I should pull to confirm it.
4. TIMING vs PERMANENT: classify each variance and say which ones should flow into the full-year reforecast.
5. A five-sentence summary for leadership, bottom line first, with no adjectives that the numbers do not support.

Why this structure works

Most variance packs describe every line and explain none; a materiality cut, a named driver per line and a timing-versus-permanent call produce the three things leadership actually asks: what moved, why, and does it change the year.

On Pro, the materiality threshold, line groupings and reporting tone match your company's close pack and audience (board, CFO, business-unit leaders) from your profile.

When to use it — and when not to

Reach for it when

• The month has closed and leadership wants to know what moved versus budget, why, and whether it changes the full-year outlook.
• You can actually supply the inputs it asks for ([COMPANY / UNIT] and 2 more) — this prompt is an amplifier for real context, not a substitute for it.
• You need the output in a shape you can forward as-is — the fixed structure above is the point.

Skip it when

• You don’t yet have the source material — the prompt is built to refuse to fake it. Its own guardrail: “Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it.” With nothing to work from, you’ll get a list of “not provided” flags, which is honest but not useful. Collect the inputs first.
• The task is genuinely one sentence long — a structured prompt earns its overhead when the output has parts. For quick one-off questions, just ask.

Common failure modes (and the fixes)

• Failure: letting the model drift past the prompt’s own guardrail — “Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Mark every claim I should verify externally before relying on it.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: letting the model drift past the prompt’s own guardrail — “Never use, infer, or request material non-public information (MNPI) or client-confidential data.” Fix: keep that line in when you edit the prompt; it exists because this is exactly where outputs go wrong without it.
• Failure: filling [COMPANY / UNIT] with a vague summary. The output can only be as specific as this input — generic context in, generic deliverable out. Fix: paste raw specifics (real names, real numbers, real constraints), then trim the model’s output, not your input.
• Failure: accepting the first pass. Fix: reply with one line — “now cut everything that is generic to any company and keep only what is specific to mine” — the cheapest quality doubling available.
