Are these Shopify checkout rates?

No. The calculator returns retail benchmark estimates. Actual Shopify checkout, carrier account, negotiated, fuel surcharge, address, and fulfillment rates may differ.

Does the calculator call carrier APIs?

No. Phase 1 uses deterministic client-side constants for zones, dimensional weight, base rates, multipliers, and a handling buffer.

How the retail shipping estimate works

This calculator uses clear constants for route zones, dimensional weight, retail base rates, per-pound pricing, delivery-speed multipliers, order-value surcharges, and a small handling buffer. It is meant for planning and benchmarking before you quote a shopper or compare fulfillment options.

What to enter

Origin and destination: country plus postal or ZIP code for the shipping lane.
Weight and dimensions: carriers often charge the greater of actual and dimensional weight.
Order value: higher-value parcels may need more careful handling or included coverage.
Speed preference: compare lower-cost, balanced, and urgent retail benchmarks.
