How to use
- Choose a filled rectangular joint or a right-triangular corner bead. Enter total length, width and depth in the indicated units.
- Enter the cartridge or sausage volume from the product label. Select US or Imperial fluid ounces deliberately when applicable.
- Set a chosen allowance and optional price per complete package.
- Review theoretical volume, required volume, full packages and coverage per package. Use separate calculations when joint sections differ.
Calculation method
Rectangular section area = width × depth; a right-triangular section uses half that area. With length in metres and section dimensions in millimetres, volume in mL = length × section area in mm². Add the allowance and round required volume up to complete packages. Coverage with allowance is package volume / section area / (1 + allowance / 100). Cost applies to the entire bought package count.
Worked example
A 10 m rectangular joint, 10 mm wide and 6 mm deep, has a theoretical volume of 600 mL. A 10% allowance gives 660 mL. Three 300 mL cartridges supply 900 mL, leaving 240 mL of purchase-rounding excess. At 12 USD each the cost is 36 USD. The same dimensions as a right-triangular section give 300 mL before allowance and require two cartridges after the 10% addition.
Assumptions and limits
The section is a simplified filled shape. The tool does not choose joint proportions, movement capability, backer rod, product suitability, application loss or curing conditions. A US fluid ounce differs from an Imperial fluid ounce. For different sections of the same product, combine target volumes before rounding a pooled order; summing independently rounded cartridges may overstate it.

Copy, download or print a valid result to keep the inputs with the estimate. Currency selections label your prices; they do not apply an exchange rate. Product-dependent examples should be replaced with data for the material or equipment you actually use.
