Frequently asked questions

Does this support every Amazon marketplace?

The arithmetic is general, but you must enter fees and currency appropriate to the marketplace.

Is advertising included?

Not in the default fields. Subtract expected ad cost when evaluating true contribution profit.

Why can actual FBA fees differ?

Size tier, shipping weight, storage period, category, and program rules affect charges.
