How to analyse the Fee and Economics Preview

What the analyser reads
It recognises the MSKU or SKU, net units, net sales, fee totals, advertising, costs, currency and reported net proceeds wherever those columns exist. As a cross-check it computes net sales minus fees, advertising and costs, so you can compare the figure with the net proceeds Amazon reports. Missing columns are treated as zero or labelled absent. The page does not invent rates or recreate Amazon's fee schedule.
Amazon notes that this preview can contain estimates, so it is a planning tool and not an accounting record. Use your settlement reports for the final numbers, and check units and currencies before you compare one SKU with another.
Your seller data stays local
The analyser runs in your browser, inside an isolated frame on this page that has no network access. Your file is read and written back by your own device, so it is not uploaded to TNAADO or anyone else, and nothing is stored. The advertising on this page sits outside the frame and cannot see what you choose. Sales and fee data are commercially sensitive and are not uploaded, stored or transmitted.
- Limits: 15 MB, 50,000 data rows, 200 columns and 50,000 characters per field.
- Duplicate SKU rows are combined before totals are shown.
What the analyzer reads
It recognizes MSKU/SKU, net units, net sales, fee totals, ads, costs, currency and reported net proceeds when those fields exist. The check total is net sales − fees − ads − costs. Missing columns remain zero or are labelled absent; the page does not invent a rate or recreate Amazon’s fee schedule.
