What it calculates

Use the result as a scenario, not a black box

The model converts bulk flower cost into a per-unit ingredient cost after an assumed process-loss percentage, then adds cone, packaging, direct labor and overhead. It is intended for cost accounting and pricing analysis in licensed operations, not instructions for illicit manufacturing or sales.

How the math works

Flower cost/gram = flower cost per pound ÷ 453.592. Gross flower required = target grams ÷ (1 − process-loss rate). Flower cost/unit = gross grams × cost/gram. Labor/unit = minutes ÷ 60 × wage. Total unit cost = flower + cone + packaging + labor + overhead.

Example

At $800 per pound, flower costs about $1.76 per gram. A 1 g unit with 5% process loss requires about 1.053 g of input, or roughly $1.86 of flower before cone, package, labor and overhead are added.

FAQ

Questions about this calculator

Why does process loss increase flower cost per unit?

Because more input material must be purchased to produce the target net fill when some material is lost during handling.

Can I use this for multi-packs?

Yes. Model the total grams and packaging cost for the multi-pack as one finished unit.

Does this calculate retail price?

No. Feed the resulting unit cost into the product pricing or wholesale margin calculator.
