COGS per Block Calculator

Cost of goods sold (COGS) per block is the all-in variable cost to produce one fruiting block: substrate, spawn, packaging, and the energy and labor of sterilization spread across a batch. This calculator builds COGS up from each component so you can see what is actually driving your cost — effectively a per-block cost calculator and price estimate calculator in one, itemizing the materials bill before you set a sale price — and it feeds directly into margin and profit.
