Formula Used
Dry raw mass = wet raw mass × (1 − raw moisture ÷ 100).
Dry extract mass = wet extract mass × (1 − extract moisture ÷ 100).
Wet yield = wet extract mass ÷ wet raw mass × 100.
Dry yield = dry extract mass ÷ dry raw mass × 100.
Drug extract ratio = raw material mass ÷ extract mass.
Marker recovery = marker in extract ÷ marker in raw × 100.
Solvent recovery = recovered solvent ÷ used solvent × 100.
Total batch cost = raw cost + solvent loss cost + processing cost.
How to Use This Calculator
Enter the wet raw material mass and choose its unit. Add the raw material moisture percentage. Then enter the final extract mass, its unit, and its moisture percentage. Add solvent use, recovered solvent, marker strength, target marker strength, and cost values. Press the calculate button. The result appears above the form. Use the CSV or PDF buttons to save the same batch report.
Extract Calculator Guide
What This Tool Measures
An extract calculator helps compare input material with final extract output. It is useful for herbal, food, cosmetic, laboratory, and production batches. The tool converts all mass values into kilograms. Then it adjusts each mass for moisture. This gives a cleaner view of real solids. Wet results are helpful for packing and shipping. Dry results are better for technical comparison.
Why Dry Yield Matters
Moisture can hide true production performance. A batch may look strong by wet weight. Yet it may contain more water than expected. Dry yield removes that confusion. It shows how much dry extract came from dry raw material. This helps teams compare different suppliers, seasons, and process settings.
Understanding Extract Ratio
The extract ratio is often called DER. It tells how many parts of raw material created one part of extract. A 10:1 ratio means ten kilograms of raw material made one kilogram of extract. The dry ratio is usually more accurate. It removes water from both sides of the comparison.
Marker and Standardization Checks
Many extracts are judged by a marker compound. This may be caffeine, polyphenols, curcuminoids, or another measured compound. The calculator compares marker strength in raw material and extract. It also estimates marker recovery. A high recovery suggests good transfer. A low recovery may show poor extraction, heat loss, filtration loss, or weak raw material.
Cost and Profit Planning
The calculator also estimates batch cost. It includes raw material cost, solvent loss cost, and processing cost. It then compares cost with expected sale price. This shows cost per wet kilogram, cost per dry kilogram, gross profit, and margin. These numbers support pricing, quoting, and production planning. They also help identify waste before scaling up a process.
Best Practice
Use verified moisture values and lab-tested marker values. Record solvent recovery after each batch. Keep raw material units consistent across production records. Export each calculation for traceability. Review dry yield, marker recovery, and cost together. One number alone rarely tells the full story.
FAQs
1. What is an extract calculator?
It estimates extract yield, extract ratio, marker recovery, solvent recovery, and batch cost from production or lab data.
2. What does DER mean?
DER means drug extract ratio. It shows how much raw material was needed to produce one part of extract.
3. Why does the calculator use dry mass?
Dry mass removes water from the comparison. This gives a fairer view of yield, strength, and process efficiency.
4. Can I use this for herbal extracts?
Yes. It works well for herbal extracts, botanical powders, food extracts, cosmetic extracts, and similar production batches.
5. What is marker recovery?
Marker recovery estimates how much of the active marker moved from raw material into the final dry extract.
6. What if my marker is below target?
The calculator shows the concentration factor needed. You may need more concentration, blending, or a stronger raw material source.
7. Does solvent recovery affect cost?
Yes. Lower recovery increases solvent loss. That raises batch cost and may reduce the final production margin.
8. Are CSV and PDF reports included?
Yes. Submit the form with either export button to download a CSV spreadsheet or a simple PDF report.
