Check Unit Sales Needed to Offset a Promotional Price Markdown
A ten-percent discount does not need ten percent more sales. Because every markdown comes straight out of gross margin, calculate the exact extra units each product line must sell just to keep total gross profit whole.

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the markdown margin chart: your product line | gross margin percent before discount | baseline unit sales stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: A 10 percent price cut on a 25 percent margin product requires 66.7 percent more unit volume just to stand still. After: the markdown margin chart shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Boundary and sources
Promotional break-even unit arithmetic on margins you supply. Not pricing or accounting advice; include payment fees, shipping subsidies and ad spend before approving a promotion.
- Method: Enter the percentage discount off the selling price; it must stay below the product’s gross margin percentage or every unit sold loses money.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.

Optional AI formatting, not calculation
For this markdown margin chart, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a markdown margin chart. Return plain rows only: product line | gross margin percent before discount | baseline unit sales. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: product line | gross margin percent before discount | baseline unit sales. No AI response is executed as code.
