Tariff impact on profit margin calculator

Automatic duty lookup is not available yet. Enter a duty rate or amount you have confirmed, for example with your customs broker, to get real results. The worked examples use example rates.

Start from your current shipment, then change the tariff, freight, supplier price or selling price. See what moves for each SKU: landed cost, contribution, margin points and the price that keeps your target margin.

This page uses the same shipment as the landed cost calculator. Your inputs stay in this browser.

Reading the comparison

The baseline is your shipment as entered. The scenario changes only the inputs you set; everything else stays the same, so each difference can be traced to its cause.

Tariff change adds percentage points to every SKU's duty. For a SKU with a broker amount or a lookup, the extra duty is the customs value times the added points, so it needs a customs value.
Duty included in the supplier price cannot be changed by points; model it as a supplier price change instead.
Freight and other costs can be replaced with new totals; they are split the same way as the baseline.
New selling price replaces the net price for that SKU. Landed cost stays the same; contribution and margin move.

A scenario is a what-if you choose. It is not a forecast of future tariffs, and it does not predict how sales would respond to a higher price.
