Free Shipping Calculators for E-Commerce Sellers
Calculate DIM weight, FBA fees, USPS Cubic eligibility, box fit, carrier comparisons, and import duty estimates before a package or product eats your margin. Carrier and Cubic tools use US domestic services. Amazon tools use US marketplace FBA. Import duty estimates US entry fees for goods imported into the United States; destination VAT/GST is labeled separately.

Shipping Tools. Every Margin Decision Covered.
DIM Weight Calculator
→Are you being billed for more weight than your package actually weighs?
Overbilled DIM weight is the most common hidden shipping cost for ecommerce sellers.
Smart Box Finder
→What is the smallest box for your items and which carrier is cheapest?
The wrong box adds billable DIM weight before the package leaves your hands.
FBA Fee Calculator
→What is your true margin after Amazon takes every fee?
Most sellers calculate margin before storage, placement, and returns processing fees.
USPS Cubic Calculator
→Does your package qualify for USPS Cubic pricing instead of standard rates?
Qualifying for Cubic does not always beat standard Ground Advantage—compare both rates before you ship.
Carrier Savings Engine
→Which carrier is actually cheapest for your specific box dimensions and zone?
The cheapest carrier for your neighbor's product may not be the cheapest for yours.
Oversize Surcharge Calculator
→Which additional handling or oversize fees will this box trigger?
Those accessorials often appear weeks later on the invoice, not on the label.
Import Duty Calculator
→What will duty, VAT, and the new 2026 rules cost you per unit before your shipment clears customs?
Sellers who skip the duty calculation are pricing their margins wrong before the inventory arrives.
HTS Lookup
→Find likely US HTS codes by product, material, use, or digits before modeling import duty.
Misclassified HTS codes distort landed cost projections before inventory ever ships.
Changelog
→What rate-table changes have been recorded?
The changelog lists recorded updates. It does not prove every displayed rate was audited against a source document.
Total Landed Cost Calculator
→What does it actually cost to get your product from supplier to sold on Amazon?
Most sellers exclude duty, prep, placement, and storage from their landed cost. The margin surprise comes later.
FBA Prep Cost Calculator
→Is it cheaper to prep your FBA inventory yourself or use a third-party prep center?
Most sellers who self-prep underestimate the true cost by ignoring labor, supplies, and defect fee exposure.

How DimMath Rates Work
Published References
Some calculator cells reproduce published commercial tables (for example USPS Notice 123 Ground Advantage Cubic). Other outputs are DimMath estimates from stored tables or formulas. They are not live carrier quotes. Official pages listed below are references for checking those estimates, not proof that every number was audited.
Public Changelog
Recorded calculator and table updates appear in the public changelog. Not every entry cites a source document, and not every carrier change is logged.
View Changelog →What These Rates Are Not
DimMath shows published retail and commercial base rates. Negotiated account discounts, fuel surcharge adjustments, and accessorial fees vary by account and shipment. Always verify final label cost with your carrier or shipping platform before committing to a price.

Why Sellers Use DimMath
Avoid DIM Surprises
Find out before the carrier does whether your package bills at actual weight or dimensional weight. The difference can be $3 to $8 per shipment at volume.
Choose Smaller Boxes
Model the shipping cost impact of switching box sizes before ordering new packaging inventory. Every inch matters at volume.
Check FBA Margins
Know your true Amazon margin including fulfillment fees, storage, placement, and returns before you source a product. Not after.
Estimate Duties Before Ordering
Calculate import duty exposure on new product categories before committing to a supplier. Avoid landed cost surprises at customs clearance.
What DimMath Is and Is Not
DimMath is a free shipping calculator suite built on published carrier rate data. It is not a carrier, not a shipping platform, and not affiliated with USPS, UPS, FedEx, or Amazon. The calculators show published base rates for planning purposes. They do not show your negotiated account rates, real-time fuel surcharge levels, or shipment-specific accessorial fees. For actual label prices use your carrier account, Pirate Ship, Shippo, or another shipping platform that connects to live carrier APIs.
About DimMath
Nobody talks about the moment a shipment costs more than you expected. You priced the product. You calculated the fees. You hit ship. Then the charge came through and the margin you planned for was gone. Not because you made a bad decision. Because the number you used was wrong before you even started.
DimMath was built to close that gap. Enter dimensions and weight. Compare carriers for planning. Some math stays in the browser; DIM Weight and Carrier Savings also use DimMath's estimate API. Not live carrier quotes. Public changelog for recorded updates. No login. No subscription.
