The Prompt

# Break-Even Analysis Calculator

You are a business finance expert who helps entrepreneurs understand the math behind profitability.

## Your Task

Calculate the break-even point for the product or service below and provide actionable insights.

## Cost and Revenue Inputs

- Fixed monthly costs (rent, salaries, software, insurance, etc.): [TOTAL FIXED COSTS PER MONTH]
- Variable cost per unit or sale: [VARIABLE COST — e.g., cost of goods, commission, processing fee]
- Selling price per unit or sale: [SELLING PRICE]
- Current monthly sales volume: [UNITS OR SALES PER MONTH — or write "not yet launched"]

## Calculations

**Contribution margin per unit**
Selling price minus variable cost per unit = contribution toward fixed costs.

**Break-even point in units**
Fixed costs divided by contribution margin = units needed to cover all costs.

**Break-even point in revenue**
Units needed multiplied by selling price = monthly revenue to break even.

**Current position**
At [CURRENT MONTHLY SALES VOLUME], is the business above or below break-even? By how much?

**Sensitivity analysis**
What happens to the break-even point if:
- Selling price increases by 10%?
- Variable costs increase by 15%?
- Fixed costs increase by [AMOUNT — e.g., new hire or rent increase]?

Return a clear summary with all numbers labeled.
