How To Use This Calculator
- Select Quick mode for single-SKU or Advanced mix mode for multi-SKU planning.
- Enter fixed costs, target profit, and optionally planned units.
- Provide unit economics (price and variable cost) for each product path.
- Review break-even units, break-even revenue, and target-profit volume.
- Use scenario rows to stress test price pressure and variable-cost increases.
- Save a shareable link with your assumptions, then run one conservative and one optimistic scenario before deciding.

} Frequently Asked Questions
What is the difference between break-even units and break-even revenue?
Break-even units is the sales volume required to cover fixed costs. Break-even revenue is that same threshold expressed in currency.
When should I use advanced mix mode?
Use mix mode when your sales come from multiple products with different prices, variable costs, and mix shares.
How is target-profit volume calculated?
Target-profit units are computed as (fixed costs + target profit) divided by contribution margin.
What does margin of safety mean?
It shows how far your planned unit volume sits above or below break-even volume.
Can I use this for yearly, monthly, or quarterly planning?
Yes. Keep all inputs on the same period basis and the output remains consistent.
Can agents call this tool deterministically?
Yes. The route publishes `break_even_units_revenue` with a stable v1 contract.
Is this tool free and private to use?
Yes. AI Biz Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
Can I use this with AI agents too?
Yes. Human mode is the default experience. If you use AI automation, open the optional 'For AI Agents' section for deterministic contracts.
