Eleven calculators, all free, all running entirely in your browser. They use the same constants as the rest of Trebalm, so a number you get from a tool will agree with the number in the article that explains it.
Start with the wax ratio calculator to get a starting percentage, take that into the batch calculator to turn it into grams, and check the oil phase with the blend stability calculator before you buy anything. Then make 25 grams and see what actually happens.
Every one of these gives a range rather than a single figure wherever the underlying evidence is genuinely uncertain, and says so on the page. That is not hedging. Published measurements of wax structuring power disagree by a factor of two or more depending on which oil the wax is in, and a calculator that hid that behind one confident number would be worse than no calculator at all.
Formulating
Deciding what goes in and how much.
- Wax ratio and firmness calculator
Set a product, container, wax and climate. Get a starting wax percentage and a firmness estimate.
- Wax substitution calculator
Convert beeswax into plant waxes, with honest ranges rather than a false single multiplier.
- Oil blend stability calculator
Blend carrier oils and see the fatty acid profile, oxidation risk and realistic shelf life.
- Essential oil dilution calculator for balms
Percentages, grams and drops for essential oils, checked against sensible limits by product type.
- Infusion calculator: herb to oil ratios, real yield and losses
Herb to oil ratios, absorption losses and the oil you actually recover from an infusion.
Making and selling
Turning a formula into a batch, and a batch into a price.
- Batch and container fill calculator
Turn a container count into a batch weight with overage, then into grams per ingredient.
- Formula converter: parts, cups and ounces into weight percent
Convert parts, cups, spoons and ounces into weight percent, and resolve ambiguous folk recipes.
- Balm shelf life estimator
Estimate a realistic best before date, and see which factor is actually limiting your shelf life.
- Cost per unit calculator for balms
What a balm really costs to make, including packaging, wastage and your own time.
- INCI list builder: put your ingredients in legal label order
Turn a formula into a label-ready ingredient list, in the right order, with the 1% rule applied.
- Batch code generator: traceable codes and honest best before dates
Build a traceable batch code and set a best before or PAO date you can actually defend.
