All benchmarks are anonymized aggregates. No individual user inputs are stored or shared. A minimum of 5 data points is required before any aggregate is shown.

Demand Variability (CV)

units
median EOQ
Micro-distributor (<$1M revenue)
25–100 units
SMB distributor ($1M–$20M)
50–500 units

How this data is collected
This benchmark dataset grows every time an operator uses our free tools. No sign-up required to contribute.
1
Operator runs a free calculation
Thousands of SMB operators use our free inventory tools each month — no account required.
2
Results are anonymized & aggregated
Only the numeric output (e.g. dead stock %, waste rate) is captured — never the input data or any user details.
3
Benchmarks update monthly
Aggregates refresh each month. We require at least 5 data points before showing any metric to prevent de-anonymization.
4
Industry baselines fill early gaps
Before our dataset matures, we show industry averages from CSCMP, APICS, and Gartner — clearly labeled as such.
