The method
- Add up your monthly overheads: software, website, tool replacement, insurance, workspace and so on.
- Estimate how many items you realistically make in a month.
- Divide.
Overhead per item = monthly overheads ÷ items per month
Same overheads, different makers
Both makers have £120 a month of overheads.
- Candle maker pouring 200 candles a month: £120 ÷ 200 = £0.60 per candle.
- Jewellery maker making 40 pieces a month: £120 ÷ 40 = £3.00 per piece.
Lower-volume makers need to carry more overhead per item, which is one reason one-off pieces usually need higher prices.
Use a realistic volume
If you base the share on your busiest month, quieter months won't cover your overheads. A cautious average is safer.
