Multi-product margin comparison
Add products, edit any two of cost / price / margin / markup, and see them ranked by margin. Import from CSV, export to CSV or PDF.
How it works
For each product, fill in any two of cost, price, margin %, or markup %. The other two compute automatically — same engine as the main calculator. The table ranks products by margin, so the highest-margin product gets the #1 badge. Your products save in your browser (no account needed) and persist across visits.
CSV format
Import any CSV with a header row containing some combination of these columns (case-insensitive): Product, Cost, Price, Margin %, Markup %. Extra columns are ignored. Missing values are fine — as long as each row has at least two of {cost, price, margin, markup}, it will compute.
Privacy
Everything stays on your device. Your product list saves to localStorage. We never see your data.
