Potato Market Intelligence
Potato Days of Supply
Potato days of supply estimates how long usable inventory will cover forecast demand or processor usage at a defined consumption rate. MassGain ties coverage to product, location, commitments, quality, lead times, alternate origins, and replacement prices so operationally thin positions are visible before the network total looks short.
Market Data
How to read this market
Potato days of supply estimates how long current usable inventory can cover forecast demand or processor usage at a defined consumption rate. The object should specify product, region, inventory scope, demand rate, delivery window, and whether commitments or unusable stock have been removed.
Use the measure to identify where coverage becomes operationally thin around crop transitions, promotions, plant allocations, or supplier disruptions. Pair days of supply with quality deterioration, lead times, alternate origins, contract nominations, and replacement prices so a nominal coverage number reflects the inventory that can actually serve the exposed market.

Analysis
Why this matters
Network-wide coverage can look adequate while one plant, region, or specification is already exposed. Days of supply also falls faster when quality deterioration removes inventory from the usable pool even if physical tonnes remain. The actionable signal is therefore product- and location-specific coverage measured against realistic replenishment lead time.

Potato market steady for now; Russia’s smaller crop is the salient risk
Spot prices are flat and USDA terminal reports read ‘market steady,’ but a renewed forecast for a smaller Russian harvest and recent regional harvest stress leave seasonal import timing and storage losses as the key uncertainty.

Overview
Who is this for?
This page is for procurement teams, processors, distributors, inventory planners, and finance leaders that need to calculate potato days of supply. Days of supply estimates how long current usable inventory will cover expected demand or processing usage at the prevailing consumption rate. MassGain helps users define the inventory, demand rate, region, product, specification, and period so the measure reflects actual exposure rather than a broad category average.
The metric becomes especially valuable around crop transitions, promotions, plant outages, and supplier allocations. A network may show adequate total coverage while one plant, package, variety, or distribution region has only a few weeks remaining. MassGain connects inventory with storage quality, contract commitments, demand forecasts, processor usage, supplier lead times, and regional replacement prices. Procurement can identify when to nominate or secure supplemental volume, distributors can target safety stock, and finance can estimate cash and cost exposure. The result is a forward-looking coverage measure based on usable inventory and realistic demand, with quality deterioration and sourcing lead time visible rather than ignored.
Use Case
A QSR appears to have 42 days of fry inventory nationally, but MassGain shows western distribution centers have only 19 days because the supplying plant faces an allocation. Procurement shifts approved product, advances nominations, and protects the exposed region without raising inventory everywhere.
FAQs
What is potato days of supply?
It estimates how long defined usable inventory will cover forecast demand or processing usage.
Why calculate days of supply by region or product?
Inventory, demand, quality, plants, suppliers, and lead times can differ across the network.
How does MassGain make coverage realistic?
It connects stocks with quality, commitments, demand, usage, lead times, prices, and replacement availability.
