Solventless business planning guide
Solventless ROI Calculator
Turn wash capacity, real recovery, labour and operating costs into a transparent production forecast—then pressure-test the assumptions before you buy equipment or scale a lab.
From napkin math to a usable model
A business case you can actually audit
Solventless economics are a chain. Working load sets throughput; cultivar and process determine hash recovery; press recovery determines sellable rosin; then material, labour, consumables and overhead determine whether revenue becomes estimated profit for the business.
The original calculator hid equipment cost and labour assumptions inside the model selector. This version puts every economic input on screen, supports downside and upside cases, follows the site currency and produces a summary you can carry into a planning conversation.

Methodology
How the calculator works
The model uses simple, traceable arithmetic so it can be rebuilt in a spreadsheet or reviewed line by line with finance and production teams.
working load × washes/day × days/month
= monthly WPFF processedmonthly WPFF × hash yield × press yield

What is a specification—and what is an assumption
Equipment data is based on the current Hashtek catalogue. Yield, selling price and operating-cost defaults are editable planning scenarios, not guarantees or claims about your market.

BubbleTek 30 gallon
7.5 kg WPFFThe calculator uses a 7.5 kg working load per batch.

20 kg WPFF per batchThe calculator now starts the 85T at 20 kg per batch, within its 25 kg theoretical maximum.
Second production path
Model dry-sift throughput separately
Dry-sift throughput depends on machine count, shifts, runs, working load and recovery. Keep this production estimate separate from the ice-water ROI model so material basis and end-product economics do not get mixed.

The current Tumbler specification recommends 8–25 lb (3.6–11.3 kg) of dry material per run, depending on density. Runs per shift and recovery are editable planning assumptions; validate them with your material and screen selection.
Before you approve a project
Three checks that make the forecast stronger
- 01
Validate the cultivar
Wash representative material, track fresh-frozen input by lot, and record hash recovery by micron before relying on a yield.
- 02
Use installed cost
Include the equipment configuration, collection, pumps, cold water, freeze drying, electrical, freight and commissioning that your room actually needs.
- 03
Stress the schedule
Production days are rarely the same as calendar days. Leave room for sanitation, maintenance, crop timing, staffing and sales demand.
Questions, answered
Solventless ROI calculator FAQ
What does WPFF mean in the calculator?
WPFF means whole-plant fresh frozen. The calculator treats the working load and biomass cost as fresh-frozen input unless you replace those assumptions with your own material basis.
How is the net rosin yield calculated?
The tool multiplies the fresh-frozen-to-hash recovery by the hash-to-rosin press recovery. A 4% hash yield and 80% press yield produce a 3.2% net WPFF-to-rosin yield.
Are the yield and selling-price presets guaranteed?
No. The three scenarios are sensitivity-testing presets, not promises or market averages. Cultivar, resin maturity, handling, wash parameters, micron selection, drying, pressing and sales mix can materially change the result.
Does the ROI estimate include every project cost?
No. It includes only the values entered. Taxes, financing, depreciation, facility construction, utilities beyond the per-wash input, compliance, testing and any unentered cost are excluded.
Can I use the model for dried material?
Yes, but replace the working-load and material-cost assumptions with your dried-material figures. The old rule of dividing WPFF by about 4.5 is only a rough moisture conversion and should not replace your measured incoming and dried weights.
