How do I calculate solvent loss during compounding and how much it costs?

Solvent Loss estimates evaporative and handling losses from open transfers, heated blending, and headspace, then multiplies the lost mass by solvent cost. Volatile carriers like ethanol can lose a few percent per open operation. The calculator shows whether closing a transfer, cooling the blend, or reducing hold time recovers enough solvent to matter, which on high-volume dilutions can be a meaningful line item across a year of batches.

How do I work out a dilution ratio and the resulting batch yield?

Start from your target concentration and the assay of your concentrate, then solve for the mass of carrier needed. Batch Blend Yield accounts for the combined charge minus process losses so your finished quantity reflects reality, not the paper formula. If you dilute a 100 percent concentrate to 10 percent, you need nine parts carrier per part concentrate, and the calculator adjusts expected output for any solvent loss during blending.

How much does odor changeover between batches cost my fill line?

Odor Changeover Time estimates the cleaning, flushing, and verification time needed when a strong material precedes a delicate one, and Cleaning Cost prices the labor, solvent, and lost production. Running compatible odors back to back and sequencing light before heavy cuts total changeover time. The calculators together show whether reordering the schedule or dedicating a kettle beats repeated deep cleans between clashing fragrances.

How do I keep fill give-away under control on fragrance oils?

Packaging Fill Accuracy compares your target fill, actual mean, and standard deviation to show give-away in grams and dollars per unit. With expensive fragrance oils, filling even 1.5 percent over target across thousands of units is real money. The calculator identifies how much tightening the fill distribution or lowering the mean toward the label claim, while staying legal, recovers on each production run.

How much lab and QC time will a run of samples and releases require?

Sample Lab Load estimates analyst hours from the number of samples, tests per sample, and time per test, while QA Release Time captures the full hold from submission to disposition. Together they show whether your lab can clear a spike in customer samples and lot releases without becoming the bottleneck, and where adding a shift or automating a GC method would shorten release cycles.

How do I price a custom compound and still protect margin?

Quote Margin builds up from ingredient cost, Batch Blend Yield, Solvent Loss, changeover and cleaning, Regulatory Documentation effort, and Waste Disposal Cost, then compares that loaded cost to your quoted price. Ingredient Cost Sensitivity lets you stress the aroma chemicals most likely to move. This shows whether a quote survives a swing in a key material or an unexpected extra QC cycle before you commit to a price.
