When to use this calculator

• Before listing a new product so you know the minimum viable selling price.
• When ad costs or supplier quotes change and you need to protect margin quickly.
• When comparing product ideas and trying to avoid offers that only work on paper.

Worked example

A product costs $16 from the supplier, shipping adds $5, ads average $12 per sale, and payment or marketplace fees add another $3. To keep a 20 percent net margin, you need a selling price of roughly $45. That is the price check that tells you whether the idea still fits the market before you buy traffic.

Decision guide

The calculator is most useful when it helps you choose between launching, fixing the offer, or killing the idea early.

• If the price lands above the market ceiling, reject the product or renegotiate supplier and ad costs.
• If the price works but conversion is weak, improve creative or the offer before cutting price.
• If shipping or fees are volatile, keep a buffer and rerun the math before scaling spend.

What to do next

Use the price floor to decide whether the product belongs in your catalog, then validate the rest of the operating model around it.
