About this calculator
Fragrance load is expressed as a percentage of the total wax weight, so fragrance oil to add = wax weight × fragrance load%. Most wax suppliers publish a recommended range for their specific wax — commonly around 6-10% for soy wax — and that ceiling is also bounded by IFRA (International Fragrance Association) usage limits for the specific fragrance oil, since some fragrance compounds are restricted to lower percentages for safety.
Hobbyist and small-batch candle makers use this to hit a consistent scent throw across every batch instead of eyeballing fragrance oil by pour, and chandlers running a small candle business use the same math to keep formulations repeatable and within their wax manufacturer's and IFRA's recommended limits batch after batch.
