Who We Serve
Freight brokers, shippers, 3PL and warehouse operators, logistics coordinators, procurement managers, supply chain analysts, and students.
How We Build
Server-rendered pages for speed and SEO, calculations that run instantly in your browser, and reference data sourced from NMFTA, carrier tariffs, and GLEC.
Why we built SupplyChain.tools
Supply chain teams spend hours every week on the same handful of calculations - freight class density, dimensional weight, pallet build-outs, safety stock, reorder points, landed cost. The math is well understood, but the tooling is scattered across spreadsheets, paywalled platforms, and outdated PDF references.
SupplyChain.tools brings those calculations and reference datasets into one fast, searchable site. Every formula is documented, every lookup is text-first and screen-reader friendly, and every page is built to be indexable by search engines and answerable by AI assistants.
We're independent, ad-light, and not trying to upsell a TMS, WMS, or freight brokerage. The platform exists because the people who keep goods moving deserve better tools than a folder of legacy XLS files.
What you get on SupplyChain.tools
Freight & transportation calculators
Freight class, dimensional weight, CBM, pallet build, container loading, fuel surcharge, TL vs LTL, and carbon emissions.
Browse calculators →Inventory & planning math
Inventory turnover, reorder point, safety stock, lead time, EOQ, ABC analysis, and landed cost.
See all tools →Lookup tools
Search SCAC carrier codes, NMFC commodity codes and freight classes, and USDOT / MC carrier records.
Open lookup tools →Supply chain glossary
Clear definitions for the terms that show up in RFPs, tariffs, and ERPs - searchable, categorized, and growing.
Open glossary →Our commitment to accuracy
Every calculator is built from industry-standard formulas and validated against authoritative sources. Results are estimates - always confirm with your carrier, broker, or supplier before contractual use.
- NMFTA density tables for freight class assignment.
- Carrier-published divisors (UPS, FedEx, USPS, DHL) for dimensional weight.
- GLEC Framework emission factors for transportation carbon estimates.
- APICS / CSCMP inventory management formulas for safety stock, ROP, EOQ, and turnover.
- CBP / WTO HS guidance referenced in landed-cost duty calculations.
Frequently asked questions
Is SupplyChain.tools really free?
Yes. Every core calculator, lookup tool, and glossary entry is free to use without an account. A free profile unlocks saved calculations and some advanced pro calculators. We may introduce optional paid features in the future, but the core reference tools will stay free.
Do you store the numbers I enter into a calculator?
No. Inputs run entirely in your browser. Nothing about your shipment, SKU counts, or pricing is transmitted unless you explicitly save a calculation to your own logged-in profile.
Can I link to or cite SupplyChain.tools?
Absolutely - linking, embedding screenshots in training materials, and citing definitions are all encouraged. Please don't scrape and republish the underlying datasets verbatim.
How do I request a new tool or glossary term?
Use the contact page. Requests from working practitioners with a real use case go to the top of our queue.
