Cost per gram is the simplest unit‑economics metric: total cost divided by sellable grams. If you don’t know this, your pricing is guessing.
- Use sellable output (after QC), not harvested weight.
- Include variable costs first; add overhead second.
- Recalculate whenever your workflow or inputs change.
Decision path
- If you’re pricing below cost per gram, you’re paying to work—fix it.
- If overhead dominates, improve utilization before buying more gear.
- If costs jump, identify whether it’s materials, labor, or losses.
- Pick a time window (batch, month, quarter).
- Add variable costs: inputs, consumables, packaging tied to output.
- Add labor time cost (even if it’s your time).
- Add allocated overhead (rent, utilities, software) for that window.
- Divide total cost by sellable grams (after rejects).
- Compare to your real price per gram and set a margin target.
Cost per gram isn’t about being cheap. It’s about knowing what must be true for profit.
Quick example
Simple cost per gram breakdown:
| Component | Example cost | Notes |
|---|---|---|
| Variable inputs | $180 | Media, nutrients, consumables. |
| Packaging | $120 | Only what’s used for sellable units. |
| Labor (your time) | $200 | Example: 4 hrs × $50/hr. |
| Overhead allocation | $150 | Utilities/software share. |
| Sellable grams | 300 g | After QC rejects. |
Formula: (180+120+200+150) ÷ 300 = $2.17 per gram (example). Use your numbers.
- Dividing by wet/uncured weight instead of sellable grams.
- Leaving labor out because “it’s just me.”
- Treating overhead as zero until it hurts you.
- Not tracking rejects (rejects are costs).
- Using one good batch and pretending that’s the average.
FAQ
Do I need perfect numbers?
No. You need useful numbers. Start conservative and improve accuracy over time.
Should I include equipment purchases?
Treat big equipment as overhead over time, not as a one‑time variable cost.
How often should I update cost per gram?
Any time your inputs, process, or quality gate changes. Quarterly minimum.
