YOUR INPUTS
Complete every field. The result updates only when you choose Calculate.
Add SKU count, average units on hand per SKU, average daily sales rate per SKU, your days-of-supply threshold, and average unit cost.
Units on hand divided by daily sales rate gives actual days of supply, which is compared against your threshold to find excess days.
Excess days are converted into excess units and multiplied by unit cost to show the working capital tied up, alongside a 0–100 overstock-severity score.

No. OverstockIQ computes results only from the figures you enter — it does not connect to any live inventory management system, POS, or ERP. It is a planning calculator, not a live inventory feed.
Run this calculator per SKU or per SKU group with similar sales velocity, or use blended averages across a representative group entered as the SKU count.
Days of supply is units on hand divided by average daily sales rate — a standard inventory-planning measure of how long current stock will last at the current sell-through pace.
It scales how far your actual days of supply exceeds your threshold, capped at 100. A higher score means a larger share of your target buffer is being exceeded.
It is a genuine calculation (excess units × average unit cost) based on the numbers you provide, but it will only be as accurate as your inputs — verify with your own inventory records for decisions.
