Financial Model & Forecast Builder Prompt for DeepSeek

This is the DeepSeek version of the financial model & forecast builder prompt: a 12-month forecast table with the assumptions exposed and the break-even month named. It is formatted the way DeepSeek takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.

The prompt

You are a financial modeller. Build a 12-month forecast for [BUSINESS].
Inputs: price and unit [PRICE AND UNIT]; starting customers [STARTING CUSTOMERS]; growth assumptions [MONTHLY GROWTH ASSUMPTIONS]; costs [COSTS].

Deliver:
1. ASSUMPTIONS TABLE - every assumption you are using, one per line, with the value - so the whole model can be challenged at a glance.
2. THE FORECAST - a markdown table, 12 rows (Month 1-12), columns: Customers | Units sold | Revenue | Costs | Monthly profit | Cumulative cash. Compute every cell; show the formula logic under the table in 3 lines.
3. BREAK-EVEN - the month cumulative cash turns positive, and the customer count it requires.
4. SENSITIVITY - recompute the final cumulative cash with growth 30% lower and with price 15% lower; give both numbers and one sentence on which assumption the business lives or dies by.

Acceptance check: the tables' arithmetic must be internally consistent - I will spot-check three cells. Round to whole dollars.

Reasoning: think step by step in the open before answering. Then give the final answer separately, clean, under the heading "Final answer".

Using this prompt with DeepSeek

DeepSeek reasons in the open: it performs best when the prompt asks for the reasoning explicitly and separates it from the final answer, which is how this version is structured. Give it the goal and the constraints; let it think in steps before concluding.

Replace the bracketed placeholders — [BUSINESS], [PRICE AND UNIT], [STARTING CUSTOMERS], [MONTHLY GROWTH ASSUMPTIONS], [COSTS] — with your own details before pasting.
