Batch Scaling Calculator

Scaling a candle recipe from small test batches to larger production runs can be difficult without accurate calculations. Even small mistakes in scaling can affect fragrance load, wax ratios, and candle performance. This batch scaling calculator helps candlemakers convert small formulas into larger batches while maintaining the correct ingredient ratios. Whether you're increasing production for wholesale orders or preparing larger manufacturing batches, this tool ensures your candle formula remains consistent at any scale.

Fragrance load is calculated as a percentage of the total pour weight (wax + fragrance), matching the convention used by most container wax suppliers. Cure time scales with batch size in production but not formulation — plan accordingly.

Recommended Supplies for Scaling

Scaling gets easier when you stick with consistent material systems. You can browse candle wax options, compare virgin coconut soy wax, or shop performance cotton wicks when preparing larger production batches.
