Frequently Asked Questions about Dropshipping & E-Commerce Profit Calculator

How is the break-even selling price calculated?

Break-even price is: (COGS + Shipping + CAC + Import Tax) ÷ (1 − Platform Fee %). This is the minimum selling price at which you neither profit nor lose money before advertising.

Is my store financial data uploaded to any server?

No. All calculation logic runs 100% locally inside your browser. Nothing is uploaded or transmitted.

What is the difference between Profit Margin and ROI?

Profit Margin is Net Profit as a percentage of Selling Price (how much of each sale is profit). ROI is Net Profit as a percentage of Total Cost (how much return you get on your investment). Both metrics are shown — use Margin for pricing decisions, ROI for investment decisions.
