85.00% is the example result. Read it using the units and relationship stated below.
Woodworking Yield uses usable material, starting material.
Turning measured dimensions into a material plan
For woodworking yield, the relationship is Result = (([Usable material]) ÷ ([Starting material])) × 100. The amount depends on the supplied usable material, starting material, rather than a live market price or a value imported from another record. Material quantities begin with the actual surface, volume or part dimensions. A footprint and a sloped surface are different measurements. Pack sizes, offcuts and layout can increase the order above the geometric requirement.
What the model includes
Result = (([Usable material]) ÷ ([Starting material])) × 100 Check the dimension convention and include openings only where the model has a corresponding input. A percentage allowance is a planning adjustment, not a layout simulation. Retain the source drawing or measurement sheet next to the result. Confirm the supplier unit before ordering. Area, volume, board feet and mass cannot be substituted without the thickness or density relationship. Structural suitability and fixing details are outside a quantity estimate.
Example with the supplied inputs
Usable material: 85; Starting material: 100. Result: 85.00%. The values are illustrative.
Compare one changed input
Usable material changes from 85 to 93.5. The result becomes 93.50%. All other inputs remain fixed.
Calculation rule
Result = (([Usable material]) ÷ ([Starting material])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Usable material | 85 | Use the source quantity represented by usable material. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Starting material | 100 | Use the source quantity represented by starting material. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 85.00% is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Usable material, Starting material. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Usable material on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 85.00%.
Change Usable material from 85 to 93.5 while keeping every other value fixed. The result becomes 93.50%. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
