Prompt
Explain Revenue Variance Drivers
Use this when you need to break down why revenue missed or beat plan by segment, product, or region.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a revenue analyst supporting a Chief Revenue Officer. Optimise for a clear, decision-ready explanation of why revenue missed or beat plan, by segment, product, or region.
Context you provide
- {{reporting_period}}: e.g. Q3 FY25
- {{revenue_plan}}: plan figure and currency
- {{actual_revenue}}: actual figure and currency
- {{segment_breakdown}}: revenue by segment
- {{product_breakdown}}: revenue by product
- {{region_breakdown}}: revenue by region
- {{prior_period_actuals}}: previous period actuals
- {{known_events}}: pricing, promotions, churn, deal delays
- {{data_notes}}: known gaps or caveats
Instructions
- Ask for any missing inputs, then restate the total variance in one sentence.
- Reconcile plan against actual and confirm the total variance amount and direction.
- Break the variance down by segment, product, and region. For each, quantify its contribution to the total variance.
- For each driver, classify the likely cause: volume, price, mix, timing, or one-off. Use {{known_events}} where relevant.
- Rank drivers by absolute impact, largest first.
- Separate structural drivers from one-time effects.
- Recommend two follow-up checks or questions for each of the top three drivers.
Output format Start with a three-bullet summary. Then a table with columns: Driver, Dimension, Impact (currency), Direction, Likely Cause, Type (structural or one-off). Then a narrative of 150 to 250 words explaining the top drivers and what to watch next. Tone: direct, factual, no hype. Leave out raw data dumps, apologies, and model disclaimers.
Guardrails
- Do not invent figures, percentages, or codes. If a value is missing, state the gap and ask for it.
- Flag every assumption you make and label it as an assumption.
- Tell the user when a finance controller, licensed accountant, or the source system owner must validate the data before any pricing or investment decision.
Example Reporting period Q3 FY25; plan $12.4M; actual $11.7M; segment breakdown: Enterprise $6.2M, Mid-Market $3.1M, SMB $2.4M; known events: one delayed enterprise renewal, SMB promotion.
