Finance prompt of the day

October 9, 2026 · for Investment banking, sales & trading, equity research, FP&A. One sharp, copy-paste prompt — free, every weekday.

You are a modeling reviewer auditing a spreadsheet model I describe or paste (formulas, structure, key outputs). Produce a MODEL-INTEGRITY review covering:
1. STRUCTURAL risks: hardcodes inside formulas, broken/inconsistent references, sign errors, units/period mismatches, and inconsistent time axes.
2. LOGIC checks: does the balance sheet balance, does the cash flow tie to the balance sheet, are there unintended circularities, and are the switches/scenarios wired consistently.
3. A SANITY-CHECK set: the ratios and cross-foots (margins, growth, returns) that should be eyeballed and any that look implausible given what I provided.
4. A PRIORITIZED fix list: the errors most likely to change the output, first. Do not assume a value I did not give you — flag it as unverified.

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.

How to run “Model integrity / error & formula-audit review”, step by step

The situation this prompt is built for: Before a model goes to a VP or IC, you want a structured audit for the errors that quietly corrupt outputs. Below is exactly what to feed it and what comes back — no model-specific tricks, it runs the same in any chat AI.

What the model hands back

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

1. STRUCTURAL risks: hardcodes inside formulas, broken/inconsistent references, sign errors, units/period mismatches, and inconsistent time axes.
2. LOGIC checks: does the balance sheet balance, does the cash flow tie to the balance sheet, are there unintended circularities, and are the switches/scenarios wired consistently.
3. A SANITY-CHECK set: the ratios and cross-foots (margins, growth, returns) that should be eyeballed and any that look implausible given what I provided.
4. A PRIORITIZED fix list: the errors most likely to change the output, first. Do not assume a value I did not give you — flag it as unverified.

Why this structure works

Model errors are precision theater — a confident output resting on a hardcode or a broken link; a structured integrity checklist plus balance/tie checks catches the corruptions that no amount of pretty formatting reveals.

On Pro, the audit checklist arrives ordered by your firm's most common model review findings from the profile you set once.

When to use it — and when not to

Reach for it when

• Before a model goes to a VP or IC, you want a structured audit for the errors that quietly corrupt outputs.
• 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.

Adapting today’s prompt for adjacent roles

“Model integrity / error & formula-audit review” sits in the Financial Analysis & Modeling lane of the finance pool. If your seat is one desk over, these are the same craft-move rebuilt for the neighbouring workflow — pulled from the same curated pool, each free in full at its permalink:

You are a deal-team member preparing for a management presentation / diligence session on [TARGET, sector, deal context]. Produce a QUESTION BANK organized by theme: 1.…

You are a trader building an EARNINGS reaction playbook for [TICKER, report date]. I will give the setup: consensus, whisper if known, implied move, key levels,…

You are an analyst interpreting a 13F filing for [MANAGER]. I will paste the holdings/changes. Produce: 1. The notable NEW positions, ADDS, TRIMS, and EXITS in a TABLE…

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: 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.
