How to use this tool

  • Pull fees from Seller Central

    Open the Amazon Revenue Calculator or your category fee schedule and note referral percent and FBA fulfillment for the size tier.

  • Enter price and landed cost

    Use the planned sale price and your true landed COGS, including duties where they apply.

  • Allocate optional costs

    Add inbound shipping, storage, advertising, and other costs on a per-unit basis for a realistic margin.

  • Review profit and break-even

    Check profit per unit, margin, and break-even sale price before you commit to a list price.

Assumptions and limits

  • Seller-provided fees

    Referral percent, FBA fulfillment, and other Amazon fees are estimates you enter. They are not fetched from Amazon and are not guaranteed current.

  • Per-unit model

    All inputs are treated as costs for a single unit sold. Volume discounts and monthly storage minimums are not modeled.

  • Referral on sale price

    Referral fee is calculated as a percent of sale price. Confirm whether your category uses a different basis in Seller Central.

  • Not tax advice

    Sales tax, VAT, and income tax are excluded. Use your accountant for filing decisions.

How to use the results

  • Negative profit

    Raise price, cut ads, or renegotiate COGS before sending more inventory to FBA.

  • Thin margin

    Leave room for returns, storage spikes, and PPC tests when margin is under 15%.

  • Fee changes

    Re-run the calculator whenever Amazon updates size tiers or referral rates for your category.
