Stress-test a student business idea
Use your own small-test assumptions to see whether the unit economics are worth testing. The calculator does not estimate demand or guarantee profit.

Run a 14-day test before scaling
- Speak to five plausible buyers and record their exact problem, not just compliments.
- Offer the smallest paid version to a clear customer group.
- Track enquiries, paid sales, delivery time, variable cost and repeat interest.
- Continue, change the offer or stop based on observed evidence-not excitement alone.
What this calculator does not know
It cannot know whether people will buy, whether your numbers are realistic, or whether the work fits your studies and responsibilities. It only makes the arithmetic of your assumptions visible.
