Use the calculator

Pick What You're Making

Choose your project type, enter the size and your preferred strength, and see exactly how much wax/base and fragrance you need. No mental maths.

Candle Calculator

Enter the total weight of wax your jar holds (water-fill method - or pick a PCS jar below) and your preferred fragrance loading.

Your inputs

Tare jar on scales, fill with water to ~1cm from rim, weight = grams of wax needed.

Fragrance load

Most container waxes max at 8%. PB75 Gel caps at 5%. Above 12% can cause sweating.

You'll need

Per candle

Wax 262g
Fragrance oil 23g
Total 285g

Rounded to the nearest gram. Multiply by your batch size to scale up.

How the maths works: total weight × load percentage = fragrance. Total weight − fragrance = wax to melt.
