Cannabis Flower Infusion Potency Calculator
A free infusion potency calculator for cannabis processors. Calculate how much distillate, live resin, live rosin, kief, or THCa to add to reach a target potency, or calculate the expected final potency of a wet, dry, or combined flower infusion. Both directions return the all-in material cost of the batch as you build it.
Built by the makers of the FX-8 Flower Infusion Machine, the calculator also runs an FX-8 check alongside the math. It converts your wet add into reservoir volume, returns the cycle count and batch time at the machine's rated flower load, and flags a batch that would need a mid-cycle refill.

Infusion Potency Calculator
Input flower
Wet add — distillate / live resin / rosin / HTE
Dry add — THCa isolate / bubble hash / kief / sift
Wet / dry split — by mass of added concentrate
Keep one cannabinoid basis. The mass balance is exact only when every potency is on the same basis (all THCa, or all total-THC). Decarbed wet oil reads as THC; raw flower & dry add read as THCa. Mixing bases? Convert first — THCa × 0.877 ≈ THC.
Running this by hand for every batch? The FX-8 automates wet & dry infusion at 8 lbs per 5-minute cycle.

Meet the FX-8 Flower Infusion Machine
This calculator runs the same wet-and-dry mass balance the FX-8 was engineered to execute at production scale. Instead of dialing in batches by hand, the FX-8 infuses up to 8 lbs of flower per 5-minute cycle with ultra-fine atomization — turning your target potency into pre-roll-ready ground flower and premium infused buds, batch after batch.
- ▸8 lbs per 5-minute cycle. Industrial throughput that replaces hours of manual labor.
- ▸Ultra-fine atomization. Even, inside-out coating with no oversaturation or clumping — feeds straight into pre-roll machines.
- ▸Wet & dry in one machine. Distillate, live resin, live rosin, kief, and THCa.
- ▸Enclosed, clean & safe. Three-stage air filtration — pre-filter, HEPA, and carbon — plus low-temp control protect terpenes and operators.
© 2026 Detroit Dispensing Solutions. The FX-8 Infusion Potency Calculator is a free planning aid. Results are estimates based on the values you enter and assume a consistent cannabinoid basis; actual potency varies with material composition, terpene cuts, decarboxylation, moisture, and process conditions. Always confirm final potency with accredited laboratory testing. Throughput figures vary by input material, environment, and operator experience. ROI and payback figures are simplified estimates based solely on the material, bag, sale, and operator figures you enter — they exclude energy, facility, packaging, taxes, and other operating costs, and are not a guarantee of financial performance.

It is a mass balance. Total cannabinoid mass divided by total batch mass gives the finished potency. Flower contributes its mass multiplied by its potency. Every concentrate you add contributes the same way, at its effective potency after any terpene cut. Add the contributions, divide by the combined weight of everything in the drum, and that is the number. Infusion does not raise potency by itself. The result always lands between the potency of the flower and the potency of what you added.
Concentrate needed equals flower mass multiplied by the gap between your target and the flower potency, divided by the gap between the concentrate's effective potency and your target. Using the calculator's defaults: 4 lb of 22% flower, distillate testing 92% with a 3% terpene cut, target 45%. That returns 943 g of concentrate, or 2.08 lb, for a finished batch of 2,757 g at 45.00%.
It changes the basis, not the cannabinoid count. THCa sheds a carboxyl group when heated and becomes THC, and THC is the lighter molecule. Multiply THCa by 0.877 to get THC. Raw flower, kief, hash, and THCa isolate report THCa. A decarbed distillate reports THC. Convert everything to one basis before running the balance. Running a THCa flower figure against a THC oil figure overstates the result.
A terpene cut dilutes the concentrate, so it lowers effective potency and raises the mass you need to hit the same target. Two conventions are in use and they do not return the same number. As a share of the final terped blend, effective potency is the lab number multiplied by one minus the cut. As a share added to the distillate's own weight, it is the lab number divided by one plus the cut. At 92% lab with a 3% cut the two land at 89.24% and 89.32%. At a 10% cut they land at 82.80% and 83.64%. Match the convention your supplier uses.
No. The relationship is not linear and it steepens fast. At 4 lb of 22% flower at 89.24% effective potency, a 30% target needs 245 g of concentrate, a 45% target needs 943 g, and a 60% target needs 2,358 g. Raising the target from 30% to 45% nearly quadruples the concentrate required. The ceiling is the effective potency of the concentrate itself. As the target approaches it the required mass climbs without limit, and above it there is no solution at any volume.
