Actual interface / Fictional sample data
Keep products, materials, labor, overhead and packaging together.
Compare order sizes, discounts, shipping charged and shipping cost.
Enter one combined percentage on pretax order revenue, plus a fixed fee.
Choose a net-margin target and rounding increment; unsupported combinations are flagged.
Export the comparison as CSV, print it, and retain full JSON workspace backups.
Enter produced and lost units, material quantities, labor time, overhead and per-unit packaging.
Compare retail with wholesale using your own fees, discount, shipping and order size.
Check the target suggestion against the actual scenario, then export a report and a separate JSON backup.
The sample makes 12 mugs with one unsellable unit. Materials of $25.20, labor of $60 and overhead of $12 are spread across 11 sellable mugs. Adding $1.25 packaging gives about $10.09 production cost per sellable mug, before the order's shipping and fees. These are example inputs, not recommended costs or prices.
Fictional worked example. Check the assumptions and boundaries against your own records.
Extract the ZIP and open tool.html in a current desktop browser. No account, installation or runtime internet connection is required. Chromium desktop and mobile viewport layouts were tested; extended data entry is best on desktop. This is a browser app, not an Excel or Google Sheets workbook.
One currency label; no conversion. The percentage fee uses one shared pretax revenue base including shipping charged. Mixed fee bases, tiered platform fees, taxes, returns and accounting integrations are outside scope. Fee rates are your inputs, not maintained platform data. Results depend on the costs you enter.
