Your next candle batch, weighed out
Plan different container sizes in one recipe. Get the wax and fragrance weights, then see how far your ingredients will go.
For 6 candles · 1,080 g prepared mixture

Starting values are examples. Use the measured wax + fragrance mass of a successful test pour, excluding the vessel. A jar’s fluid-ounce label is not its finished fill weight.
1 · The shared recipe
8% means 8 g oil for every 100 g wax.
Use the percentage and limits specified for your wax and fragrance. The calculator does not choose a safe load, wick or curing time.
2 · Containers to fill
Each group shares the same recipe. Different fragrances or wax blends need separate plans.
Group 1
Up to 8 groups. Each pour target includes wax and oil; extra mixture is held separately.
3 · Ingredients you have optional
Weigh for this batch
1,080 g to prepare = 1,080 g to fill containers + 0 g extra mixture.
Same recipe in both conventions: 8% of wax = 7.407% of finished mixture. These are ingredient ratios, not recommended fragrance levels.
Every pour, at a glance
Teal: wax · Gold: fragrance. Fill height represents mass per candle, not physical liquid level. Select a pour to edit it.
Pour list
Test candles · 6 containers
180 g finished mixture eachPer container: 166.667 g wax + 13.333 g oil.
Group fill: 1,080 g.
Mix the batch before dividing it among the containers. Per-container ingredients explain the ratio; the extra allowance is separate. Display rounded to 0.001 g; use a suitable scale. Arithmetic does not guarantee the physical fill level or burn performance.
Your ingredient stock
Shortage for one planned batch: Unknown wax · Unknown oil.
Enter both available quantities to calculate complete batches. For unscented candles, only wax is needed.
Measuring fill mass and reading the plan
Weigh a successful test candle and subtract the empty vessel, lid and other non-mixture parts. Use the net wax-and-fragrance target for the same recipe and fill line. Changing the wax, fragrance or ratio may change the fill level; verify with a test pour. This tool does not infer a universal density from jar volume.
The pour list excludes the extra allowance. Ingredient totals include it. For stock planning, one complete batch repeats every group and the allowance; it does not choose which individual candles to omit. Stock leftovers are after all complete batches, not after buying the shortage for one batch.
Formula and numerical limits
Finished fill = sum of each container count × its fill mass. Prepared mixture = fill × (1 + extra/100). If fragrance is p% of wax, wax = prepared mixture ÷ (1 + p/100), and oil is the remainder. If fragrance is p% of total mixture, oil = prepared mixture × p/100, and wax is the remainder.
Complete batches = the smaller of available wax ÷ required wax and available oil ÷ required oil, rounded down. Unscented recipes need no oil. Unknown stock remains unknown. Exact input fractions determine the whole-batch count; displayed masses are rounded and are not measurement guarantees.
Software limits: 1–8 groups, 1–10,000 containers per group, 0.001–100,000 g finished mass per container, 0–100% extra mixture, and 0–1,000,000,000 g of each ingredient in stock. Percentage limits are 0–100% of wax or the equivalent 0–50% of total. These are arithmetic limits, not recommended or safe fragrance loads. Decimal input accepts a dot or comma, up to six decimal places. 1 oz = 28.349523125 g.
