About

Ecommerce Profit Tool publishes free calculators and guides to help sellers estimate order-level profit, margins, and ad guardrails before scaling spend.

How we model profit

The core calculator uses a single order-level equation: subtract product cost, shipping, platform or payment fees (entered as commission or fixed amounts), optional ad spend, and other costs from selling price. Results are educational estimates — always reconcile with your statements, tax advisor, and platform reports.

Monetization & transparency

We may add affiliate links, sponsorships, or paid products in the future. When we do, we will label them clearly next to the recommendation. The calculator remains free to use at the point of calculation.
