About SupplyChainToolkit
Our Mission
SupplyChainToolkit exists to make supply chain knowledge accessible, practical, and actionable for everyone — whether you're a student, a supply chain professional, or someone making inventory decisions for your business.
Why We Built This
Supply chain management is complex. Textbooks are dense. Spreadsheets are error-prone. Professional tools are expensive. We believed there should be a free, trustworthy resource where you could calculate EOQ, safety stock, or inventory turnover without guessing or paying for enterprise software.
SupplyChainToolkit fills that gap. Our calculators are based on established formulas from ASCM, CSCMP, and academic research. Every calculation is tested. Every page is explained. Every assumption is documented.
What We Offer
Twenty-five supply chain calculators organized by category:
- Inventory: EOQ, Safety Stock, Reorder Point, ABC Analysis, Turnover, DIO, and more
- Forecasting: Moving averages, exponential smoothing, accuracy metrics (MAD, MAPE)
- Warehouse: Capacity utilization, space efficiency, picking productivity, storage density
- Procurement: Total cost of ownership, lead time analysis, MOQ optimization, supplier scoring
Our Standards
Every calculator on SupplyChainToolkit meets strict standards:
- Accuracy: Formulas validated against academic sources and industry standards
- Transparency: Every assumption and limitation is documented
- Clarity: Each calculator includes step-by-step examples and interpretation guidance
- Accessibility: Mobile-friendly, keyboard-navigable, WCAG AA compliant
Who's Behind This
SupplyChainToolkit is built and maintained with a focus on getting the fundamentals right: accurate formulas, honest documentation of assumptions and limitations, and tools that hold up to real scrutiny — not just polished presentation.
