What does target margin mean?

The net profit percentage you want left of the sale price after every fee and cost is deducted.

Where does the FBA fee come from?

It is derived from Amazon's published US card by weight and dimensions; you can also type the fee yourself.

Fulfilment fee

Unit system

Packed weight

Weight of the PACKED unit — box and dunnage included. ⚠️ Enter the dimensions too: Amazon also prices on DIMENSIONAL weight (L×W×H ÷ 139) and for large light items the billed weight is higher than the actual one. Without dimensions the size tier is only GUESSED from weight; measured, that guess runs 9–13% LOW, which flatters your profit.

Length

Width

Height · The OUTSIDE of the box. Leave all three at 0 and the size tier is guessed from weight alone — the screen then labels it a GUESS.

FBA fulfilment fee ($/unit) — manual

Used only when "I will type my own fee" is selected; if you sell FBM switch to manual and enter your own shipping cost.

ⓘ Rounding: money lines are rounded to the nearest cent, and the total on screen is the sum of the lines on screen. The marketplace's own rounding can differ by a cent per line; in tiered rate cards the direction of that difference is not guaranteed.

The problem

Don't price by feel — price to your target margin.

Treating price as profit means forgetting commission and fulfilment. Start from your target margin and solve backwards.

🎯

Pricing without a margin

You can't list without the price that covers cost and leaves your target profit.

🙈

Hidden fees

Ignoring commission and fulfilment makes your price come out too low.

🎲

Lost sales

The wrong price either bleeds margin or loses the customer.

Features

Enter cost + margin, get your price.
