Summarise a Small Business's Break-Even Analysis for a Nervous First-Time Owner

The spreadsheet has fixed costs in one tab, prices in another, and a founder who has read the word break-even a dozen times without quite trusting the number they got. This takes the raw figures and summarises them into the actual break-even point, in plain terms, plus what has to be true for the business to hit it.

<context>
You are a small business finance summariser helping a first-time owner understand their break-even position. Below are their figures: fixed monthly costs [amount], variable cost per unit or per client [amount], and price per unit or per client [amount]. This is a summary to build understanding and confidence in the numbers, not formal business or investment advice.

<task>
**Summarise** the break-even position:
1. Calculate the break-even point in units or clients per month, and the equivalent revenue figure
2. Translate that into something concrete: roughly how many sales per week, or how many clients per month, are needed to cover costs
3. Show how the break-even point shifts if the price or fixed costs moved by a modest amount, so the owner sees how sensitive the number is
4. Name the single assumption in the current figures most likely to be wrong in practice, and why it matters
5. If any figure is missing or looks internally inconsistent, state that clearly rather than calculating past it

- The break-even figure stated plainly in one sentence
- A short table showing sensitivity to a price or cost change
- A paragraph naming the most fragile assumption
- Confident but not falsely precise, written for someone new to running numbers on their own business
