At a glance

The blended average cost of a Shippo label plotted as a sparkline over the trailing 90 days. The single line that tells finance whether despatch spend per parcel is drifting up, holding flat, or coming down as carrier mix, zone mix and surcharges shift.

​
What it tracks

A single month’s average cost per parcel tells you little; the slope tells you everything. Cost Per Shipment Trend draws the blended label cost across 90 days so finance can see whether despatch is quietly getting more expensive. A rising line usually means one of a few things: a carrier general rate increase landed (USPS and UPS publish annual increases each January, plus peak surcharges from late October through December), your zone mix shifted toward distant destinations, your parcel mix got heavier or bulkier (dimensional-weight surcharges), or a cheapest-rate selection rule stopped firing. A falling line is the reward for renegotiated rates, a better carrier mix, or right-sized packaging. Read it next to Cost by Zone to attribute a rise to a zone shift, and High-Cost Shipment Outliers to find whether a spike is a few extreme parcels or a broad creep.

​
Reconciling against the source

Cross-check the period average against total spend in the Shippo dashboard Billing view divided by label count for the same 90 days. Voided and refunded labels settle on Shippo’s own cadence, so a very recent void may still sit in the trend until the next refresh; the dashboard and the card converge once billing finalises.
