Candle Wax Quantity Calculator

Work out candle wax quantity instantly with clear inputs, formula shown and shareable results.

About Candle Wax Quantity Calculator

Containers are filled to about 90% of capacity, mass is that volume times wax density, and the fragrance load is expressed as a percentage of the wax weight so the total is split accordingly. Fragrance load above about 10% will not bind into most waxes and seeps out, which is why the percentage is calculated on wax weight rather than total weight.

Formulas

Poured mass

grams = container ml x 0.9 x wax density x candles

Wax and fragrance split

wax = total / (1 + fragrance load); fragrance = total - wax

Worked example

With the default values below, Candle Wax Quantity Calculator returns Wax needed of 1,125.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Candle Wax Quantity figure worked out?

grams = container ml x 0.9 x wax density x candles. Containers are filled to about 90% of capacity, mass is that volume times wax density, and the fragrance load is expressed as a percentage of the wax weight so the total is split accordingly.

Why does this matter?

Fragrance load above about 10% will not bind into most waxes and seeps out, which is why the percentage is calculated on wax weight rather than total weight.

What do I need to enter?

Enter container volume, number of candles, wax density, fragrance load. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
