Candle Making Calculator - Free Online Calculator Tool

Quick Answer

A candle making calculator precisely determines wax quantities, fragrance oil loads (typically 6-10% of wax weight), and batch sizes to ensure even burning, strong scent throw, and no waste[1][5]. Enter your wax weight, container count, and fragrance percentage for instant, accurate results—ideal for beginners and pros avoiding costly errors like wick clogging[1][2].

Why You Need This

Candle making without precise calculations leads to failed batches, wasted materials, and inconsistent quality, as improper ratios cause issues like poor scent throw or structural weaknesses[1][5]. Most waxes safely hold up to 12% fragrance oil, but experts recommend 6-10% (about 1.6 fluid ounces per pound of wax) to prevent burn problems and comply with IFRA standards[1][5]. Production costs average $5-5.50 per candle, making accurate tools essential for small business owners tracking inventory and achieving $7.50 gross profit per unit with proper scaling[2][4]. Beginners avoid trial-and-error, while experienced makers scale recipes efficiently for wholesale success[1][2][3].

How It Works

Input the number of candles, container size in ounces, and fragrance load percentage (e.g., 6-10%) based on your wax type[1][2]. The calculator outputs exact wax weight (in pounds or grams) and fragrance oil amount, using the total content method for vessel candles to match volume precisely[1][3]. Works for soy, paraffin, or blends, handling single candles or bulk batches seamlessly[1][2].

Tips for Best Results

• Always measure wax by weight (grams or pounds), not volume, for accuracy[1][5].
• Stay under 10% fragrance load and check supplier/IFRA limits to avoid sweating or irritation[5].
• Test small batches first, then scale outputs for full recipes and track costs in tools like inventory software for 3x markup pricing (e.g., $5 cost to $15 retail)[3][4].
• Verify results with burn tests for optimal scent throw and safety, refining within 6-10% limits[1][5].
