Inventory is getting more expensive to hold but, paradoxically, more measurable to manage. Warehouse management software is forecast to reach $70.8 billion in 2024 while only 1.4% of total supply chain cost comes from inventory carrying costs, a gap that raises a practical question about where the real pressure sits. This post pulls together today’s key inventory statistics, from accuracy and cycle counts to ecommerce shares and inventory to sales ratios, so you can see how performance is built and where it breaks.
Key Takeaways
- 10.3% of global waste was recycled in 2018
- The global supply chain pressure index declined to 45.6 in 2024 (average)
- Global retail ecommerce sales reached $5.8 trillion in 2023
- In 2022, the average US inventory-to-sales ratio for grocery was 1.26
- US retail inventories were $809.6 billion in February 2024

With tighter inventory accuracy and visibility, companies are improving turns while software markets and ecommerce reshape demand.

Even though inventory carrying costs make up just 1.4% of total supply chain cost, a 25% improvement in inventory turns from cycle counting shows that small cost categories can still deliver big operational gains.
How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
