How do you calculate days of supply for cannabis inventory?

Divide on-hand regulated inventory by expected daily release, then divide by your shelf-life and hold safety multiplier. For 1,200 units at 85 per day with a 1.1x multiplier, that is 1,200 / 85 = 14.12 raw days, divided by 1.1, for about 12.83 protected days.

What does the shelf-life and hold safety multiplier do?

It discounts your optimistic raw days-of-supply to account for product locked in compliance holds or approaching expiry. A 1.1x multiplier trims roughly 14.12 raw days down to 12.83 protected days, a deliberately conservative planning figure.

What is a good days-of-supply for perishable cannabis product?

There is no universal number, but it should sit comfortably below the product's remaining shelf life. If flower has 30 days of usable life and you carry 12.83 protected days of supply, you have healthy turnover; carrying 40 protected days against 30 days of shelf life guarantees write-offs.

Why use protected days instead of raw days?

Raw days assume every unit is releasable today, which is never true in a regulated operation. Quarantine, lab holds, and aging lots reduce what you can actually ship. The protected figure is the number you should plan and reorder against.

How does this guide production scheduling?

If protected days of supply falls below your replenishment lead time, you risk a stockout and should pull production forward. If it climbs well above remaining shelf life, you should slow production or discount to avoid expiry destruction costs.

Does this account for lot-specific expiry dates?

Not directly. The multiplier is a blended safety discount across the pool. For tight expiry management, run the calculation per lot or product family rather than on aggregate on-hand inventory.

Cannabis, Hemp & Controlled Agriculture Processing calculator

Shelf-life hold inventory Calculator

Shelf-life hold inventory tells a cannabis or hemp operator how many days of supply their on-hand regulated stock represents once you account for product that is tied up in compliance holds, testing quarantine, and finite shelf life. Cannabis is perishable: flower loses potency and develops moisture issues, edibles and tinctures carry firm expiration dates, and product sitting in a remediation or lab-hold cannot be released. Inventory planners and operations managers use this metric to decide when to pull forward production, when to discount aging stock, and when to avoid overbuilding inventory that will expire before it sells. The safety multiplier discounts raw days-of-supply to a more conservative protected figure that reflects real hold and expiry exposure.

What this calculator does

Estimate protected days of supply for finished goods, retained samples, or QA-held inventory so teams can judge release timing, aging risk, and service coverage.
Use it when shelf-life hold inventory in cannabis, hemp and controlled agriculture processing is being sized for a buffer or safety stock review.
It computes protected shelf-life days of supply by dividing on-hand inventory by daily usage and discounting by a shelf-life and hold safety multiplier.

Formula used

Unprotected days before safety multiplier = on-hand regulated inventory ÷ expected daily release or usage
Protected shelf-life days of supply = unprotected days ÷ shelf-life and hold safety multiplier

Inputs explained

On-hand regulated inventory:
Expected daily release or usage:
Shelf-life and hold safety multiplier:

How to use the result

Use it when deciding whether to pull production forward, discount aging lots, or pause buying to avoid expiry write-offs.
It assumes steady daily release; demand spikes, recalls, or lot-specific expiry dates can make actual coverage shorter than the protected figure suggests.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
