Enter parcel weight and quantity to find your carrier weight tier and optimize shipping costs.
Enter the weight per unit and the number of units. The calculator shows total weight and how it maps to common carrier weight tiers or brackets so you can see how close you are to the next tier.
You see your current tier and distance to the next. Sometimes adding a small amount of weight pushes you into a better rate; other times it's better to stay under a threshold.
Using per-carton weight when the carrier tiers are per-shipment can mislead. Tier boundaries and rates vary by carrier and service—confirm with the carrier.
