test would need.

Explore one product or service over a single test period. Change the assumptions before committing more time or money.

All money values are USD. Use net selling price after discounts. Include payment fees, delivery costs and expected refunds in your costs; do not count a cost twice.

See the formulas and assumptions

Revenue = price × sales. Cash contribution = revenue − (per-sale cash cost × sales) − fixed cash costs. Contribution per hour = cash contribution ÷ total work hours. Break-even sales = fixed cash costs ÷ (price − per-sale cost), rounded up to a whole sale.

Break-even assumes constant price and costs. With a positive fixed cost and no positive contribution per sale, extra sales cannot cover that fixed cost. When fixed cost is zero, zero sales produce zero cash contribution; selling at a loss still makes the scenario worse.

Method reference: SBA break-even explanation. This tool is an educational estimate for one offer.
