What it does
Amazon's fees stack up: a referral fee on every sale, pick and pack by size, storage by volume, returns, disposal and the seller account. It is easy to price a product and find later that the profit is gone. A general Amazon profit calculator covers the basics. This version adds the sources' rules of thumb, such as a third to product, a third to fees and a third to profit with a 30 percent floor, and the cash you need to start. The fee numbers in the source are from the video's date and some are garbled, so the skill uses them only to show the method. It tells you to check current fees in Seller Central or Amazon's own calculator and to paste those in. The score is ours: it measures how well your numbers meet the sources' rules, and it shows the sum.
You give it
- Price, landed cost, size and weight
- Expected months in stock and share of sales in Q4
- Return rate and ad spend per sale
- Current fee figures from Seller Central (optional, but best)
- Spreadsheet (optional)
You get
- Profit per unit with every fee listed
- Break-even ad cost per sale, a start-up cash estimate and a price check
- A score out of 100 for how well the numbers meet the rules, with the sum shown
Use it when
- You have a product, a price and a supplier quote, and want the real profit per unit.
- You are checking whether a price rise would be safer than running out of stock.
- You need to know how much cash you need before the first order.
How to use it
- Start a chat with the skill. Open it if you added it to your AI, or copy it and paste it in.
- Get today's fee figures for your size and weight from Amazon's revenue calculator in Seller Central, and paste them in.
- Paste your price, landed cost, size, weight, months in stock, return rate and ad spend per sale.
- Read the profit per unit and the break-even ad cost. If the score is low, change the price or the cost and run it again.
