Margin & Price-Match Calculator for Shopify von OmMarginshield

Thinking about matching a competitor's price? Check it first. This free calculator shows Shopify and ecommerce sellers their real profit margin after fees, their safe floor price — the lowest they can go and still hit their target margin — and a clear should-I-match verdict.
Browsing a competitor's product page? Highlight their price, click the toolbar icon, and pull it straight in.
No signup. No data collected — everything is calculated locally in your browser. It's the free companion to OmMarginshield, the Shopify app that monitors competitor prices across your whole catalog with margin guardrails.
