The full wax melt mould calculator guide
Work out your batch, fragrance, yield + real cost — for wax melt makers who are tired of guessing.
This is the complete companion to the quick calculation guide. It walks you through every step in full — from what your mould really holds, to two common fragrance-percentage methods, to the difference between expected and actual yield — and finishes with a reusable worksheet you can run before every pour.
Inside this guide
- 1.What your mould really holds — weigh the finished pieces of one full mould rather than estimating from mould size; if you sell a clamshell, snap bar or gift box, weigh the format you actually sell.
- 2.Calculate the full batch size — one mould weight × number of moulds = planned finished batch. Example: 96g × 10 moulds = 960g. Record real wastage instead of guessing a percentage.
- 3.Two fragrance-percentage methods explained — finished-product method vs. wax-only method. Use whichever your wax supplier or recipe specifies, keep it consistent, and always stay within the IFRA limit.
- 4.Expected yield vs actual yield — track planned batch weight, expected units, actual saleable units, leftovers and damaged pieces. This is what reveals your real cost per melt over time.
- 5.A reusable worksheet — mould name, cavities, weights, fragrance %, oil and wax amounts, expected vs actual units and notes. Keep each batch's numbers so future calculations get more accurate.
Start with the quick calculation overview, then come back for the full method.
Calculate it once. Record what actually happened. Make the next batch easier.

Tip: keep the worksheet numbers from every batch in the Pour & Track app — your calculations get more accurate the more you record.
