Pricing Model: Dimensional (Volume)

The Dimensional (Volume) pricing model is for liquids and other materials you buy by volume and use in measured amounts. You enter the total volume and purchase price; CrafterBy calculates cost per unit of volume (mL, L, fl oz, etc.), which is applied when you specify how much a product uses.

When to use it

Use Dimensional when:

• You buy the material in a container with a defined volume
• You measure out a specific volume to use per product

Good examples:

• Fragrance oil — 500 mL bottle for €18.00
• Soy wax flakes (by volume rather than weight) — 1,000 mL bag
• UV resin — 250 mL bottle for €22.00
• Alcohol ink — 30 mL bottle for €5.50
• Wood glue — 500 mL bottle for €7.00
• Epoxy resin (part A or part B separately)

Setting up a Dimensional material

1. Follow the steps in Adding a Material.
2. Select Dimensional (Volume) as the pricing model.
3. Choose the Volume Unit (mL is recommended for most craft liquids; L for larger containers).
4. Enter the Total Volume of the container.
5. Enter the Purchase Price for that container.
6. CrafterBy calculates: Cost per mL = Purchase Price / Total Volume.

Adding it to a product

When you add a Dimensional material to a product, enter the volume used per product in the same unit. CrafterBy multiplies by the cost per unit of volume.

Worked example

You buy a 500 mL bottle of fragrance oil for €18.00.

• Unit: mL
• Total volume: 500 mL
• Purchase price: €18.00
• Cost per mL: €18.00 / 500 = €0.036/mL

Each candle uses 30 mL of fragrance oil.

• Material cost: 30 × €0.036 = €1.08

A larger pillar candle uses 50 mL.

• Material cost: 50 × €0.036 = €1.80

Two-part materials

For two-part materials like epoxy resin (resin + hardener), create a separate material entry for each part, with its own volume and price. Add both to the product at the appropriate ratio (e.g., 2:1 resin to hardener). This gives you accurate cost tracking if the two parts have different prices or come in different bottle sizes.
