How this calculator helps

The cheapest headline price is not always the cheapest landed total. This calculator totals price after discount plus shipping for three offers.

Formulatotal = price×(1−discount/100)+shipping

Discount model

Each offer’s discount is applied to that offer’s item price before shipping is added. If your promotion applies differently, adjust inputs to match.
