How much does resin cost per piece?

A small resin coaster (100 ml) typically costs £1.50-3.00 in materials. Larger pieces like chopping boards or river tables cost significantly more. The main cost is the resin itself, followed by pigments and moulds.

How do I amortise mould cost?

Divide the mould price by the number of times you expect to use it. Good quality silicone moulds last 50-100+ uses. A £10 mould used 50 times costs only £0.20 per piece.

What sundries should I include?

Sundries include mixing cups, stir sticks, gloves, sandpaper, polishing compound, and wax paper. These typically add £0.20-0.50 per piece. For commercial production, include labels and packaging too.

How do I price resin pieces for sale?

Material cost should be 20-30% of your selling price for handmade items. So if materials cost £3, aim to sell for £10-15. Factor in your time, overheads, and platform fees. Use the Selling Price Calculator for detailed pricing.

How We Calculate This

How the Calculation Works

Resin cost is calculated by converting volume to weight (volume x 1.1 g/ml density), then multiplying by the price per kilogram.

Mould cost is amortised across the expected number of uses. Pigment and sundries costs are added per piece. The formula is:

Cost per piece = resin cost + pigment + (mould cost / uses) + sundries
