How do I use the Profit Calculator?

Updated Sep 26, 20261 min read

The Profit Calculator & Real Share panel works out your profit on a product.

What you enter

  • Cost Price is what you pay per unit. Plug Seller remembers it for that product in this browser.
  • Sale Price starts at the Buy Box price. Type another price to try it out.
  • Fulfilment Type is FBA or FBM.
  • Storage (Months) is for FBA only. It's how long you expect the stock to sit at Amazon, and it starts at 1 month.
  • Shipping to buyer is for FBM only. Check shipping price gets a live rate, or you can type your own.

What you get

FigureHow it's worked out
ProfitThe sale price minus total fees and your cost.
ROIProfit divided by your cost.
Maximum CostThe most you can pay and still meet your targets (how it's worked out).
Total FeesClick it to see each fee: referral, FBA, closing, storage, prep and misc.
Profit MarginProfit divided by the sale price.
Breakeven Sale PriceThe sale price at which your profit is $0.
Estimated Amz. PayoutThe sale price minus Total Fees, before your cost.

Profit, Maximum Cost and Estimated Amz. Payout also open a breakdown when you click them.

Until you enter a cost, Profit equals the payout and ROI shows ∞%.

The FBA / FBM switch at the top of Quick Info changes the fees for the whole page at once.
