How to Use This Calculator

Enter flower input in grams and flower THC potency from lab testing.
Set decarboxylation efficiency (%) and infusion efficiency (%) for your process.
Enter servings per batch and your target mg THC per serving.
Review THC per Serving (mg), Total THC in Batch (mg), and Compliance Status.
For adult-use compliance, target ≤10 mg THC per serving and ≤100 mg per package.

How the result changes with Servings per batch

Flower input (g): Grams of cannabis flower to infuse (a quarter ounce = 7g).
Flower potency (% THC): THC/THCA potency from lab testing.
Decarb efficiency (%): Decarboxylation efficiency (typically 85-95% with proper technique).
Infusion efficiency (%): Percentage of decarbed THC that transfers into oil/butter (60-90%).
Servings per batch: Number of individual servings in the recipe batch.
Target mg/serving: Desired THC milligrams per serving (10mg is standard adult-use limit).

THC per serving (mg): Actual milligrams of THC in each serving.
Total THC in batch (mg): Total available THC across the entire batch.
THC per package (mg): Total THC per 10-serving package (regulatory metric).
Flower for target dose (g): Grams of flower needed to achieve your target mg/serving.
THCA in flower (mg): Total THCA present in input flower.
THC after decarb (mg): Active THC after decarboxylation.
THC after infusion (mg): THC that made it into the oil/butter.
Flower cost/serving: Estimated flower cost per serving (at $8/g).
Compliance (1-3): 1 = Adult-use compliant (≤10mg), 2 = Medical range (10-50mg), 3 = Exceeds most limits.

Identify Input Parameters
4 parameters
Flower input (g) = 7, Flower potency (% THC) = 20, Decarb efficiency (%) = 88, Infusion efficiency (%) = 75 = 6 input(s) provided
Calculate THC per serving
40.52 = 40.52
Calculate Total THC in batch
Total THC in batch = totalTHCAfterDecarb * (infusionEfficiencyPct / 100)
810.35 = 810.35
Calculate THC per package
THC per package = mgPerServing * servingsPerPackage
405.17 = 405.17
