A WORKBENCH GUIDE · UPDATED OCTOBER 9, 2026
Price stained glass with your materials and time in view.
A piece-count shortcut can miss expensive glass and hours at the bench. Start with the costs you can measure.
Build your project cost
- Add the glass, foil or came, solder, and other materials allocated to the piece.
- Multiply your labor hours by the hourly rate you choose.
- Add overhead as a percentage of materials plus labor.
- Choose a markup or a target margin, keeping the two distinct.
The app does not choose a market rate, tax treatment or wage for you. Use your own costs and compare the resulting estimate with the work and selling conditions.
A worked example
These are fictional amounts in one consistent currency, not recommended prices.
| Input | Amount |
|---|---|
| Glass | 50 |
| Foil or came | 10 |
| Solder | 5 |
| Other materials | 5 |
| Labor: 2 hours × 15 | 30 |
| Overhead for this example | 0% |
| Break-even project cost | 100 |
Markup is different from margin
A 20% markup adds 20% of cost: 100 × 1.20 = 120. Profit of 20 divided by the price of 120 gives a margin of about 16.7%.
A 20% target margin instead uses cost / (1 − margin): 100 / 0.80 = 125. Profit of 25 divided by 125 is 20%.
With 10% overhead on materials plus labor, the same cost base becomes 110. Then a 20% markup gives 132 and a 20% target margin gives 137.50.
Don't lose the assumptions
Record the materials allocated, hourly rate, hours, overhead and adjustment mode alongside the estimate. Consider packing, selling fees, delivery and rework where relevant; include them deliberately in your cost assumptions rather than assuming the app knows them.
Material quantities are also estimates. Read the glass, foil, came and solder guide before quoting from rough inputs.
